Google announced it has expanded its sensitive category blocking feature for AdSense to Japanese, Chinese, Polish, and Portuguese. The goal is to expand it worldwide eventually.

The feature is already available in English, French, German, Spanish, Italian, Dutch, and Arabic (with testing being done for Russian).

With the feature, users can prevent ads from up to 11 categories from appearing on their pages. "Ads in these categories will be blocked if they’re in any of the supported languages, regardless of how they’ve been targeted to your pages," says Google’s Katrina Kurnit.

Setting category blocking can be done from the Ad Review Center in your AdSense account. This can be found in the AdSense Setup tab.

"Once you click ‘change,’ you’ll be able to view the full list of categories you can block," says Kurnit. "In addition, to help you understand the impact of applying these filters, we’ll show you the percentage of revenue and ad impressions you’ve been receiving from each category in the last 30 days."

Categories that can be blocked include: cosmetic procedures and surgeries, dating, drugs and supplements, get rich quick, politics, religion, ringtones and downloadables, sexual and reproductive health, sexually suggestive, video games (casual or online), and weight loss.
