Encouraging clicks In Google Adsense

In order to ensure a good experience for users and advertisers, publishers may not request that users click the ads on their sites or rely on deceptive implementation methods to obtain clicks. Publishers participating in the AdSense program:
May not encourage users to click the Google ads by using phrases such as "click the ads," "support us," "visit these links," or other similar language
May not direct user attention to the ads via arrows or other graphical gimmicks
May not place misleading images alongside individual ads
May not promote sites displaying ads through unsolicited mass emails or unwanted advertisements on third-party websites
May not compensate users for viewing ads or performing searches, or promise compensation to a third party for such behavior
May not place misleading labels above Google ad units - for instance, ads may be labeled "Sponsored Links" but not "Favorite Sites"
