AdSense advertiser quality report

Sites Percent Rating
695 13.9% Site ownership and business identity verified. No significant issues found.
1975 39.5% Site ownership identified but not verified.
543 10.9% No information available.
1790 35.8% Site ownership unknown or questionable, or significant negative information about the business was found.

A rather high fraction of Google AdSense advertisers are rated as “site ownership unknown or questionable, or significant negative information about the business was found.” These are the ones for which we could not find the business behind the web site. We suggest dealing with such sites with caution. Users with AdRater installed will see the Red do-not enter icon displayed atop ads for such sites.
