If you are adsense publisher sometime you might have noticed totally unrelated ads appearing in your pages. For example site related to vacation might display an irrelevant advertisement related to dental surgery. To filter and control, adsense has introduced a new feature in the Ad Review Center called Category Filtering. With this feature, publishers will have control over the ads appearing on their sites and have ability to block ads that fall into specific categories such as dating, drugs & supplements, and politics.
Also, adsense will show the percentage of recent revenue that ads in each category generate. This feature is in beta to a small group of publishers to collect initial feedback about the feature.
