Site and Ad Behavior

Sites showing Google ads should be easy for users to navigate and should not contain excessive pop-ups. AdSense code may not be altered, nor may standard ad behavior be manipulated in any way that is not explicitly permitted by Google.

* Sites showing Google ads may not contain pop-ups or pop-unders that interfere with site navigation, change user preferences, or initiate downloads.
* Any AdSense code must be pasted directly into webpages without modification. AdSense participants are not allowed to alter any portion of the code or change the behavior, targeting, or delivery of ads. For instance, clicks on Google ads may not result in a new browser window being launched.
* A site or third party cannot display our ads, search box, search results, or referral buttons as a result of the actions of any software application such as a toolbar.
* No AdSense code may be integrated into a software application.
* Webpages containing AdSense code may not be loaded by any software that can trigger pop-ups, redirect users to unwanted websites, modify browser settings, or otherwise interfere with site navigation. It is your responsibility to ensure that no ad network or affiliate uses such methods to direct traffic to pages that contain your AdSense code.
* Referral offerings must be made without any obligation or requirement to end users. Publishers may not solicit email addresses from users in conjunction with AdSense referral units.
