Google advertiser quality update

Our latest statistics on the quality of Google’s advertisers may indicate a slight downward trend. Of 20247 Google AdWords advertiser domains seen in the last 60 days, we see the following ratings.

Sites Percent Rating
1964 9.7% Site ownership and business identity verified. No significant issues found.
7729 38.2% Site ownership identified but not verified.
3715 18.3% No information available.
6839 33.8% Site ownership unknown or questionable, or significant negative information about the business was found.

Most notably, the percentage of sites in the highest category, those where the identity of the business behind the site was verified by a trusted third party, has decreased.

Our sample size has increased substantially, which has some effect on the data. This data comes from users of our AdRater plug-in, and the number of AdRater users has increased substantially in the last month. When we rate an ad for a user, we accumulate data about advertiser behavior. We don’t collect data about what users are doing; just advertisers.

This data includes only ads served by Google’s US-based ad servers.

We will be reporting this data periodically.
