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.
