SiteTruth.net posted results for the past 60-days of his AdRater extension, which looks at "advertiser legitimacy for text ads on web pages."
The report collected 11,355 domains over the past 60-days and showed that about 55% of those were either questionable domains or unknown domains. The break down is as follows:
- Verified Site 11.60%
- Identified But Not Verified 30.70%
- Not Rated Site 21.60%
- Questionable Site 36.20%
He said:
12% of sites get our highest rating, down from 14% in 2008. 36% of the ads rate our “site unknown or questionable” rating. This percentage has held constant since we first did this analysis in 2008. 21% of sites are not rated. These are typically blogs, or sites where we don’t see commercial activity or ads. This is twice what we saw three years ago.
Overall, since the last time they ran this study, he said the landscape for these advertisers have no changed much.
I am not sure how valid this study is, but I figured I put it out there.
