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.
