Tips for maintaining an AdSense-friendly site with user-generated content

These days, user-generated content is everywhere, from the comments below newspaper articles, to the photos and videos shared on social networks. So it's no surprise that many publishers are monetizing this type of content with AdSense ads. But, while you're familiar with types of content which are compliant with the AdSense program policies, your users might not be. We understand that it's not always easy to monitor hundreds of new comments, posts, user profiles, videos, or photos every day, so here are a few ideas on how to maintain an advertiser-friendly environment on your pages.

As a quick note before we head into the tips, remember that inappropriate content can come in many forms -- images, forum posts, comments, links, and so on. For example, adult content isn't only limited to pornographic images; it can also be sexually explicit forum posts or spam bot comments with links to adult sites, which aren't permitted by our policies. We recommend reviewing our previous Inside AdSense post on this topic for further clarification and a few tests you can try on your content.

Now for the tips, which we've divided in two sections - 'Prevention' and 'Monitoring'.

Prevention

Here are some recommendations for ways to prevent your ads from appearing alongside user-generated content that isn't compliant with our policies:

1. Publish clear content guidelines and policies that your users will have to accept and adhere to in order to sign up and use your site's services.
   
   
2. If you own a photo or video sharing site where users are permitted to upload adult or other non-compliant content, clearly structure your content to avoid placing your ad code in sections/categories containing this type of content. The same idea could also be easily applied to online stores with adult sections or to classifieds sites which offer adult dating classifieds.
   
   
3. Ask users to tag their inappropriate content (e.g. sexually suggestive pictures or videos) as being non family-safe. This can help you perform human evaluations of potentially inappropriate content for AdSense ads. You can also try installing keyword filters for content related to adult topics, violence, or drugs, for instance. While we're unable to provide you with details about setting up these filters for your site, we recommend searching for terms such as "keyword filtering" or "content filtering" on Google.com.
   
   
4. Implement spambot protection for your comment forms, forums, and guest books. If you need more information on this topic, try a Google search for "spambot protection".
   

Monitoring

We suggest these tips to ensure that your existing user-generated content pages remain compliant with our policies:

1. Set up ways for your community to monitor itself. For example, try adding a "Report inappropriate content" link to your pages, to allow users to flag content for you to review.
   
   
2. Proactively review pages, videos, photos, etc. with high pageviews on a regular basis.
   
   
3. Spot-check content based on keywords, content search, or related user accounts. For example, try entering keywords related to inappropriate content in your own search engine and checking the results. Alternatively, you can search on Google.com using the following parameter, replacing 'example.com' with your own site's URL and 'keyword' with a specific word or phrase: "site:example.com keyword".
   
   
4. Create editorial policies and exercise moderator control in your comments, forums, and guestbook sections.
   

We hope you find these tips helpful. You can also read related information and suggestions from our Search Quality Team in a recent post on the Webmaster Central Blog. If you have any other ideas, or if you've already implemented similar measures on your sites with user-generated content, please feel free to leave a comment below and share your experience.

Updates to the program policies page

If you've checked the AdSense program policies page today, you've probably noticed that we've just made a few small updates. We'd like to take a moment to clarify what's been changed.

The first thing you might notice when you visit the program policies page is that we've revamped the look. Based on your feedback, we've reorganized the content and updated the layout to make it easier to read and navigate. We've highlighted some key information for each policy, and added expandable 'Learn more' sections that you can click for more detailed information. Also, we've grouped together policies that are specific to only AdSense for content or AdSense for search.

There are also a few updates to the content of the program policies, which we've outlined below:

• Google brand violations: This policy has always existed in our Terms and Conditions, but we've now brought it directly to the 'Ad Placement' section of the program policies page so that it's easier to find. According to this policy, we don't allow ads or search boxes to be placed on pages which misuse Google logos, trademarks, or other brand features in the page content or URL, and which could mislead users into thinking the page is associated with Google.
  
  
• Deceptive implementations: We've clarified this policy a bit in the 'Encouraging Clicks' section of the program policies - ads may not be formatted in a way that makes them indistinguishable from other content on the page where they appear. This includes, for instance, formatting content to mimic ads, aligning images with ads, and placing ads under a misleading heading.
  
  
• Ad placement in emails and email programs: This updated policy clarifies that Google ads , search boxes, and search results may not be placed in emails, as well as alongside emails.
  
  
• Other Google products' policies: With this new policy, publishers aren't permitted to place ads, search boxes, or search results on, within, or alongside other Google products in a way that violates the policies of that other product or service. For instance, this would include placing ads on sites which allow users to download YouTube videos, which isn't permitted by the YouTube Terms of Service.
  

Finally, we've added more information to the 'Webmaster Guidelines' section and created a new 'Traffic Sources' section. Whether you regularly review the program policies or haven't reviewed them since you signed up for AdSense, we encourage you to visit the program policies page and check out the updates.

(Post has been updated to provide additional clarification.)

My content, your content, other people's content

Sometimes we receive reports about AdSense code appearing on websites that may contain content copied from other websites. We understand that many of our publishers are concerned about this issue, so we'd like to give you some information about the procedures and tools you can use to protect your content.

For example, let's suppose you own a movie blog, where you recently posted an article about your favorite actor. After publishing it, you notice that another website has copied and published your article without your permission. The owner of the other website doesn't respond to your requests to remove the content, and it is monetizing their pages with AdSense.

In a situation like this, where you believe that a site containing AdSense code is illegally copying your site's content, you can let us know by following the process described in our Help Center. It's our policy to respond to notices of alleged infringement that comply with the Digital Millennium Copyright Act and other applicable intellectual property laws.

The notice should be sent directly from the owner of the copyrighted materials allegedly being infringed (in the example above, that's you), as we are unable to accept third-party copyright complaints. Also keep in mind that we are unable to process copyright complaints received through the AdSense policy violation report form. Once we've received a notice of infringement, we will take appropriate action. If you'd like more information about our DMCA process, please visit http://www.google.com/adsense_dmca.html.

Additionally, if you find a site that is scraping (misappropriating and republishing) your content, you can report it for a potential violation of the Google Webmaster Guidelines. To do this, fill out the form at https://www.google.com/webmasters/tools/spamreport (you must be logged into your Google Account to access this form).

Is it right to search on your own site?

If you've added an AdSense for search box to your page, you're probably aware of the relevant search results it provides your users. That being said, a few publishers have asked us if it’s a violation of our program policies to perform searches in their own AdSense for search boxes. The short answer is no, this activity is not explicitly prohibited by our program policies.

However, we strongly advise against using your own AdSense for search box for a couple of reasons. First, it can increase the chance of accidental or invalid clicks on the ads that appear on the search results pages. Second, this will inflate the number of queries in your reports, giving you an inaccurate picture of the activity on your site.

If you’d like to use Google search, we recommend visiting Google.com or installing the Google Toolbar. And if you're using Google Chrome, don't forget that you can type search queries directly into your address bar.

Defining invalid clicks and click fraud

We often receive questions from new publishers about what these two terms mean, and we'd like to help you understand the difference.

Invalid clicks are clicks for which we decide not to charge our AdWords advertisers, since they may artificially drive up advertiser cost or publisher revenue. These include extraneous clicks without any value to the advertiser, such as the second click of a double-click. They also include many other types of clicks that we've determined aren't motivated by genuine user interest.

"Invalid clicks" are often confused with "clicking on your own ads". However, we'd like to stress that invalid clicks are generally any clicks that artificially inflate advertiser cost or publisher revenue, regardless of their source.

Click fraud is a subset of invalid clicks that are generated with malicious or fraudulent intent -- in other words, clicks that are intended to drive up advertiser cost or publisher revenue artificially. Sources for these clicks include, but are not limited to:

A publisher clicking on his own ads, or encouraging clicks on his ads

Users or family members clicking to support the site / publisher

Third-party programs with user incentives, such as paid-to-click services and click-exchanges

Automated clicking tools, robots, or other deceptive software

The same principles above apply to ad impressions and conversions as well. Some sources of invalid impressions include, but are not limited to:

Excessive page refreshes, generated either manually or automatically

Third-party programs with user incentives, such as paid-to-surf or auto-surf programs

Third-party programs for purchasing fixed amounts of traffic, e.g. "$10 for 1,000 page views"

As a reminder, any method that artificially generates clicks, impressions, or conversions is strictly prohibited by our program policies. You can also find more information about these topics in our Invalid Clicks FAQ and our Ad Traffic Quality Resource Center.

Sharing your ad space

A number of publishers have asked us if it's acceptable to place multiple publishers' ad code on the same page or site. Often they'll run into this issue when two AdSense publishers manage a site together and both want to display their ads, or if a site owner hosts content and ads from other publishers on the same page as their own.

The answer is that yes, we do allow this. But before you place your ad code on the same page or site as another publisher, here are a few important points to keep in mind:

• The maximum number of products per page will remain the same.
  
• If you don't own the site, you'll need to receive permission from the site owner to display your ads on their pages.
  
• We're unable to divide earnings between accounts, so any revenue generated will be credited to the account associated with the ad unit that was clicked or viewed.
  
• Any shared site that displays Google ads must also comply with our program policies.
  
• You're responsible for the content of any page where your ad code appears. Before placing your ad code on another publisher's site, we recommend reviewing the site for any policy violations.
  

And one final tip before giving your code to another publisher -- try using our Allowed Sites feature to monitor where your ads are appearing and keep your account in good standing.

Promoting your referrals -- properly

Some of our publishers have asked us about the policies surrounding promotion for referral units, and so we'd like to address two of the most frequent areas of confusion. While the policies are generally the same for referrals as for standard AdSense for content ad units, there are a few minor differences.

Recommending products vs. encouraging clicks

We previously addressed this topic, but we'd like to remind you of the policy and provide some additional clarification. You can endorse or recommend products you've chosen to refer on your sites, but we ask that you only make recommendations when you're familiar with the specific product and you've decided not to use the 'Pick best performing ads' feature for that ad unit. For example, if you're familiar with a specific travel agency you're referring, you may use language such as "I use this agency and recommend it to book your next vacation." By being honest with product recommendations, you can help build user loyalty and trust, which will benefit your site in the long run.

You may be wondering why we allow publishers to call attention to referral units but not standard ad units. This is because there are significant differences between these two types of ads, the most important being that advertisers only pay for traffic from referral units if the user performs a specific action the advertiser has designated (such as making a purchase from the site or signing up for a newsletter). Please keep in mind that there is a fine line between recommending a product and encouraging your users to click on a referral button for personal profit. Publishers may not ask users to click on the referrals to help them earn money, and may not refer themselves to their own referral products. In addition, publishers may not draw unnatural attention to their referral units with arrows pointing to the units or other similar methods.

Using online advertising

As is true for all sites displaying AdSense ad units, referral units, or search boxes, your site must comply with Google's Landing Page Quality Guidelines (LPQ) if you'd like to use online advertising of any kind as a traffic source. The term 'online advertising' refers to a range of methods, from advertising programs such as AdWords to posting your site within a link exchange or in a forum. However, if the primary purpose of your site is to generate conversions from referral ads, you'll need to go one step further before advertising your site. You'll need to first receive permission from the advertisers whose products you're referring before advertising your site or their products. Please note that Google has made the decision to not allow publishers to use online advertising for any of the Google products or those of our Google Pack partners.

Another look at optimizations

We've given you many optimization tips over the years, and, as you know, it's important to consider how your ad implementations affect not only your click-through rate, but your users' and advertisers' experience as well. To support this, we'd like to remind you of the following two guidelines when optimizing your site.

1. Ads shouldn't be placed under a title or section heading in a way that implies that the ads are not ads.
For example, ads shouldn't be placed under titles such as “Dallas Business Opportunities” or “Today's Hot Deals”. Placing ads directly below titles such as these implies to your users that the links in the ads are publisher-created content. The example below shows a placement that does not follow this guideline.


2. Ads should be easily distinguishable from surrounding content.
Similarly, you should not place an ad unit by a group of links that has identical colors and line spacing. Doing so may cause users to think the ad unit is content created by you. In this situation, we recommend using a different color for the ad titles or indenting the ad unit to help distinguish the ads from your own content. This screenshot shows an implementation that does not follow this guideline:

As you can imagine, users who click on ads that they think are publisher-created content may lose trust in your site and decide not to return in the future. It's important to keep their interests in mind, as well as your own.

Also, advertisers can tell which sites have a high conversion rate for them using Placement Performance reports. A conversion occurs when a click on an ad leads directly to user behavior that the advertiser deems valuable, such as a purchase, sign-up, page view, or lead. Advertisers have the option to exclude your site from their campaigns and may do so if it is not leading to conversions.

We believe these guidelines invest in the long-term health of the relationship between AdSense publishers, AdWords advertisers, and your sites' visitors, and that they will help ensure your continued success in the AdSense program.

Engaging users with policy-compliant images and video

As it's becoming easier and easier to embed videos and pictures on websites, many publishers are now enhancing their current text content with relevant videos and photos. We wholeheartedly support adding these different forms of content to improve the user experience on your site -- hey, we like watching entertaining YouTube videos too! But here's a friendly reminder about keeping our program policies in mind when you choose video and image content for your site.

Before posting videos or pictures on a page with Google ads, put yourself in an advertiser's position and consider whether you would want to have your ad displayed on the page. If your content might potentially be seen as offensive or disturbing, an advertiser may not be comfortable running their ads on that page. Here are a few specific types of content that you can check for:

• Adult or mature: Includes, but is not limited to, images and videos containing sexual activity, full nudity, and lewd poses. Please review this recent post to determine whether your content might fall into this category.
  
• Violent or gory: Can include images and videos of street-fighting, people hurting each other, or gruesome accidents and their victims.
  
• Culturally insensitive or hate speech: Includes content promoting racial intolerance or advocating against a specific individual, group, or organization.
  

Also, keep in mind that publishers may not place AdSense ads on pages involved in the unauthorized distribution of copyrighted materials. Unauthorized copyrighted materials include music, movies, images, or any other copyrighted material that the publisher does not own or license from the copyright owner.

The list above is by no means exhaustive, since there are always some borderline cases which will feature content that may be tame to one person but offensive to another. If you're uncertain about specific pictures or videos, we recommend that you err on the side of caution and refrain from placing this content on pages containing Google ads. In addition, if you host a site with user-generated content, we ask that you continually monitor your network to ensure that ads don't appear alongside the types of content described here.

Posted by Dan Zilic - AdSense Publisher Support

Play it safe, family-safe

Many of our publishers regularly ask what is exactly considered adult or mature content by AdSense policies. It's a lot easier to understand when we speak about family-safe content. As you may already know, only ads classified as family-safe will be displayed on AdSense publisher websites.

Our policy regarding adult or mature content may include any material that is not appropriate for all audiences. While this obviously includes full nudity or sexual activity, it may also include textually explicit sexual content, image or video content containing lewd or provocative poses, strategically covered nudity, see-through or sheer clothing, and close-ups of anatomy that would be inappropriate if shown nude. Additionally, topics such as sexual health and sex tips may be held to a higher standard of professionalism than content that isn't bordering on mature.

While it's not a sure test, we sometimes suggest that publishers ask themselves the following questions to determine if content is family-safe: Would I be comfortable viewing this content with my parents or children in the same room? Would I feel comfortable viewing this content if my boss walked up behind me while I had this content on my screen? If the answer to either of these questions is no, then it is likely that some advertisers would not be comfortable showing their ads on such content and we might consider it mature.

Policy updates -- and it's not even Thursday!

After our many weeks of policy posts on Thursdays, you're probably intimately familiar with all of our program policies. So we can imagine your surprise when you woke up today, got your morning coffee, and settled in for your daily re-read of the policies -- only to find they were different! To help lessen the shock, we've highlighted the two notable changes below:

We're now requiring AdSense publishers to comply with the spirit of our Page Quality Guidelines. If you're an AdWords advertiser, you might already be familiar with these guidelines, which are intended to provide a better experience for users, advertisers, and publishers alike. If you use any kind of online advertising, know that these guidelines encourage publishers to, among other things, create sites with simple navigation and substantial, useful content.

This new policy requirement doesn't mean that you can't use online advertising; it simply means that if you do, you need to be sure that the way you advertise meets with the guidelines, whether it's through AdWords or through any other advertising program. However you advertise your site, it can always benefit from significant and relevant content, clear navigation, and the other points in our quality guidelines.

The other noteworthy update: now you can place up to three link units on a page. As we've noted in the past, link units are a great way to provide relevant, user-friendly ads in hard-to-fit locations on your site. With the new opportunity to place three link units -- and the plethora of link unit formats -- we hope you'll find great ways of incorporating this unique ad format on your site.

Accidents happen

As most of you know, our program policies state that publishers are not permitted to click on their own ads for any reason. For this reason, we've received many emails from publishers letting us know that they've accidentally clicked on their own ads. If you're one of these publishers, we truly appreciate the efforts you've made to monitor your account and keep it in good standing. However, we do understand that an accidental click may occur from time to time, so there's no need to contact us each instance this occurs.

Because we closely monitor all account activity using engineering systems and thorough human analysis, chances are we've already detected your clicks on your ads and discounted them. While these clicks still show in your reports, we filter out their associated earnings so that advertisers aren't charged. However, please keep in mind that we don't ignore the clicks completely; if it appears to us that a publisher has been clicking on his own ads to inflate his earnings or an advertiser's costs, we may disable the account to protect our advertisers' interests.

If you've been clicking your ads out of interest or to see who was advertising on your site, we strongly recommend using the AdSense preview tool as an alternative. This tool will allow you to check the destination of ads on your page without the risk of generating invalid clicks. You can also find more ways to view the URLs of your Google ads by visiting our Help Center.

Clicks for charity?

In this week's 'Policy Thursday' post, we'd like to follow up on one of Mike's previous posts to highlight a more specific example of encouraging clicks that we often receive emails about. Many publishers have asked if they can place text on their sites which states that all or a portion of the earnings generated through AdSense will be donated to charity or another third party.

While we do appreciate your charitable efforts, this practice is not permitted by our program policies. We want users to click on ads because they are interested in the products or services offered by the advertiser, not because they are interested in supporting a site or a charity. Using this type of language can draw undue attention to the ads, and we aren't able to verify whether earnings are actually donated to the third-party mentioned on each site. As a result, we don't allow publishers to offer these types of incentives.

However, please know that once you've received your payments, you're still welcome to use them however you wish - whether it's donating them to a charity, paying your hosting bills, or treating yourself to a night out on the town. We just ask that you avoid using any language on your site that would directly or indirectly encourage users to click on your ads.

A clarification on accidental clicks

We understand that there's been some confusion surrounding our recent post about accidental clicks. Specifically, many of our publishers feel that we've been sending mixed messages about placing ads near navigation controls, particularly where site optimization is concerned.

For those of you concerned about our optimization tips, we still recommend integrating your ad units and link units with your page content or navigation, in order to offer your users relevant ads in addition to the content they normally see. Here are a few examples of acceptable implementations:



However, in some instances we've found that publishers have placed their ad units so close to interactive (clickable) content that users accidentally click on the ads instead of the site content. While this type of ad placement may not inherently violate our program policies, it could increase the risk of invalid clicks being generated on the ads, which would be in violation of our policies.

You can understand that increasing the possibility of accidental clicks on your sites is not in the best interest of users or advertisers, and we wanted to make you aware of this risk. This is why we ask that you maintain sufficient distance between your ads and any elements of your page on which users may often click. Because every site is different, we can't provide you with the exact amount of space to put between these page elements. However, we hope you understand our reasoning, and we ask you to use your best judgment so as to avoid possible accidental clicks in the future.

To help you, here's an example of an ad placement that could have a high risk of generating accidental clicks, and which we'd recommend avoiding:

Don't run the risk of click and miss

As you may know, our tips and guidelines mention that "users should only click on Google ads if they're interested in the services being advertised". While there are many precautions a publisher can take to avoid encouraging clicks on their ads, we've found that some implementations of the ad code can lead to accidental clicks that the publisher may not have been able to predict. Some implementations that could lead to accidental clicks include placing your ads:

- In close proximity to Macromedia Flash games
- Under pop-ups or download prompts
- Near site navigation controls on your pages, such as drop-downs or menu links

Generally, we ask that you not place your ads near features of your site that your users may interact with by clicking. If your site contains elements that increase the number of ad clicks without increasing business results for the advertiser, we may consider these clicks to be invalid. "Business results" can range from an online sale to a page view. If we detect enough of these clicks and determine that the risk to our advertisers is too great, we may disable the account. To maintain compliance with our program policies and ensure that your users don't inadvertently click on the ads on your site, we strongly recommend that you move any ad units that are in close proximity to interactive site features.

As always, thanks in advance for your cooperation!

Encouraging clicks

Many of you may remember our December post on the placement of images near ads. In that spirit, we'd like to remind you of a general policy issue: encouraging clicks.

As many of you know, our program policies prohibit any means of encouraging users to click on Google ads or bringing excessive attention to ad units. For example, sites may not contain phrases such as "click the ads," "support our sponsors," "visit these recommended links," or other similar language that could apply to the Google ads on your site. In addition, publishers are not permitted to label the Google ads with text other than "sponsored links" or "advertisements."

In light of this policy, you may be wondering if you're allowed to recommend your referral products to your users. As explained in Dan's post from February, unlike with AdSense for content ads, you can endorse your referral products by calling attention to the button or text link. If you believe in the quality of the product that you're referring, feel free to let your users know.

Generally, visitors should only click on Google ads if they're interested in the services being advertised. Encouraging them to click on your Google ads, either directly or indirectly, can lead to inflated advertiser costs -- and can cause an account to be disabled.

If you'd like to improve the performance of your ad units and attract more interested users, check out our Help Center's optimization tips to take full advantage of what AdSense has to offer.

If it ain't broke...

We know how important it is to maintain the quality of your site and the experience your users have there, and we often receive email from publishers asking about specific ad implementations. While we encourage you to tailor your ads to fit the look and feel of your sites, we'd like to remind you to only use the options provided within the AdSense Setup tab of your account. As you may know, our program policies strictly prohibit altering the layout, behavior, targeting, or delivery of Google ads or AdSense for search boxes for any reason. Some examples of these modifications include:

- Implementing the AdSense ad code in a "floating box script"
- Manipulating the ad targeting using hidden keywords or IFRAMEs
- Altering the height or width of an ad unit
- Pre-populating the AdSense for search box with specific queries
- Creating direct links to AdSense for search results

Once you've generated the ad code in your account's AdSense Setup tab, we ask that you incorporate it into your pages exactly as it was generated, without altering any portion of the code. Doing so will also help ensure that you're properly credited for valid clicks and impressions.

A note on traffic exchange programs

We understand that our publishers are always looking for ways to attract interested users to their sites. But using third-party tools or services to increase your site traffic may lead to invalid clicks or impressions and result in your account being disabled. For this reason, we'd like to provide you with some guidance about this.

As many of you already know, our program policies strictly prohibit any means of artificially generating ad impressions or clicks, including third-party services such as paid-to-click, paid-to-surf, auto-surf, and click-exchange programs. These programs offer incentives for users to view web pages or click on ads, resulting in activity that is harmful to our advertisers.

We occasionally receive questions from publishers interested in using traffic exchanges to bring traffic to their site. While these services may help advertise your site, we don't recommend using them, as they may also result in similar invalid activity. We realize that you may have questions about a specific traffic service and whether it could potentially create invalid impressions or clicks. However, please understand that we're unable to comment on any particular third-party service.

As a parting note, we encourage you to read through our tips and guidelines and Webmaster Guidelines to help keep your account in good standing. These guidelines advise publishers to "Provide unique and relevant content that gives users a reason to visit your site first," and we feel this is ultimately the best way to attract more visitors to your site and build a truly loyal audience.

Must-read policy Thursdays

Flossing. Wearing sunscreen. Eating leafy greens. Intellectually, we know we're supposed to do these things, but it can be hard to actually buckle down and do them. The same thing is true for the AdSense program policies. You probably know the policies exist, and you know you ought to be complying with them. Still, making sure that your site stays squeaky clean policy-wise can sometimes take a little more mental effort than most of us might be willing to spare.

That's why we're beginning a weekly series of posts to help bring AdSense policies to the front of your minds -- and your sites. On coming Thursdays, you can look forward to information about:

- steering clear of possible invalid clicks
- nurturing harmonious relationships between ads and images
- why asking visitors to click your ads is a bad idea, even if you say please

We believe every publisher has the potential to be a model publisher. It's our aim to get you on the right track with some helpful tips and explanations.

After we begin our series, you might want to talk AdSense policy with your fellow publishers. So we'll be starting threads for each post in the AdSense Help Forum -- head on over after reading each post to share your thoughts.

Referral policies - clarified

We've noticed some confusion over the program policies associated with referrals. Specifically, some publishers tell us they don't understand why we allow "explicit endorsement" for referral ads, but do not allow the same type of "unnatural attention" for our AdSense for content and AdSense for search ads. We thought we'd clarify our referrals program's policies and explain why we do not allow the same treatment for other Google ads.

First, referral ads are credited on a cost per action (CPA) basis. This means that there is a specific action such as an install for Google Pack that your visitors must complete before you generate earnings. The advertiser places a certain value on that action being completed, and is willing to pay you a percentage of that value. If you highlight the referral ad and encourage more people to complete the action, the value that the advertiser places on that action does not diminish.

For example, Google is willing to pay up to $2 for each new user who downloads and installs Google Pack. If you encourage people to download and install Pack on your site and the conversion rate goes up, we're happy to pay the additional cost, because it directly translates to more Pack users for us.

However, this isn't the case for most AdSense for content and AdSense for search ads, which are served on a cost per click (CPC) or cost per thousand impression (CPM) basis. It's generally harder for an advertiser to decide on a CPC/CPM value than it is to decide on a CPA value because multiple factors go into deciding the value of a click or impression. Encouraging clicks on these ads not only drives lower quality traffic to an advertiser’s site but provides poor data for an advertiser to make an appropriate bid on the click. This results in a poor experience for visitors and advertisers, which isn’t good for you as a publisher.

Additionally, you can endorse referral ads because you know the exact ad you are displaying on your site. You are offering your visitors genuine advice based on the products and services you think they'll like. However, with CPC ads you don't know which ads will show up -- it would be disingenuous for you to recommend the products or services in your ads in this case, which could result in visitors being misled.

Of course, publishers may never encourage people to click on any ad, including referrals, for deceptive purposes. For example, you can't ask visitors to click on a referral ad to make you money. Any endorsement or attention drawn to a referral ad must be done in a way that supports the intended use of the product or service associated with it.

In short, our policies on endorsing ads are based on our concern for the visitor, the advertiser, and the publisher. We strive to make AdSense work best for all our partners.
