Avoiding accidental clicks Pt. 1: Keeping the right distance

In the past, we've talked about ad placements that are prone to generate invalid clicks. In a past post, for example, Mike noted that publishers should be careful about placing ads too close to navigational controls or other clickable page elements.

It's in the best interest of the user, advertiser, and publisher to avoid implementations that lead to invalid click activity. As you can imagine, users aren't very happy if they accidentally click an ad instead of a link on your page and are directed away from your site. Advertisers also don’t want to be charged for a click that a user made accidentally (though of course we do not charge advertisers for invalid clicks that we detect). And why should publishers care? Well, if we see that most of the clicks coming from your pages are invalid, we may need to disable your account to protect our advertisers.

One type of site we wanted to talk about are Flash-based game sites. Playing games on these sites, you'll notice that ads are often placed very close to the Flash player where the game is played. Publishers may reason that they're providing maximum value to advertisers by placing their ads very close to the area where their users are focused. However, many of these Flash games are played with a mouse, and the action in the games can lead users to do a lot of rapid cursor movements and clicking. We've seen many cases where ads were placed too closely to where the action was taking place, generating many accidental clicks.

Since each game and site are unique, we can't advise publishers on an exact distance between ads and games, but we do recommend a minimum distance of 150 pixels between the Flash player and ads.

We've worked with publishers on these issues in the past and noticed that increasing the distance between Flash player and ads has had, on average, a positive long-term effect on CPCs. The reason for this is smart pricing. As you may know, the revenue you receive is based on the amount an AdWords advertiser pays for each click on their Google ad. The amount the advertiser pays varies per ad and from website to website, based on the likelihood that a click will result in a conversion for the advertiser. If we determine that clicks on a site are less likely to lead to business results for an advertiser (e.g., an online sale or registration), we reduce the price that an advertiser will pay for those clicks.

So, in short: Moving the ads further away from Flash games decreases the likelihood of accidental clicks and increases the number of clicks leading to business results for advertisers. A good deal for all involved.

AdSense Facts & Fiction Part IV: Program policies

Fiction: AdSense disables accounts and issues warnings at random.

Fact: We rely upon a detailed set of guidelines when looking at policy violations, and these policies are published in our Help Center. Our intent is to keep Google's content and search networks safe and clean for our advertisers, users and publishers. We seek to be as transparent and consistent with our decision making.

Part of our job of monitoring the AdSense network involves working with publishers to identify and address potential issues. We understand that there are a lot of policies to take into account, and so for minor policy violations our first step will be to issue a warning. The reasons a publisher might receive a warning will vary, but in general they tend to be for violations that can be fixed fairly easily. Examples of these violations range from deceptively labeling ads “Today’s hot deals” to having a minimal amount of adult-content comment spam in a forum. Publishers, after receiving a warning, are given three days to fix their violations. If changes are not made in that time, ad serving will be disabled to the violating site.

There are some situations when we would need to disable ad serving to a site without first sending a warning. We usually reserve this action for egregious violations like adult content, copyright infringement, as well as cases of extreme violence and gore. We may also disable ads to a site when we find a violation that we’ve already contacted a publisher about in the past.

The final and most severe action that our teams can take is to close down an account completely. This normally only happens when we find that a publisher’s entire network consists of violating sites or for repeat policy offenders. If you have received a policy notification from the AdSense team, please visit this help center entry for additional information.

We want to point out that notifications that result from the previously mentioned policy violations are different from notifications sent because of issues with invalid click activity, which are monitored by Google's Ad Traffic Quality Team. Invalid click activity consists of any clicks or impressions that may artificially inflate an advertiser's costs or a publisher's earnings, and for which we decide not to charge the advertiser. For more information about invalid clicks and impressions, please refer to this page, which includes a link to our FAQ page for accounts disabled due to invalid activity.

Lastly, we highly recommend reviewing these guidelines to help avoid policy violations, and to help keep your AdSense account in good standing.

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.
