What is category filtering?

Category filtering allows you to block ads from certain categories from appearing on your site. Our system classifies ads automatically and we don't rely on advertiser-provided categorization. Right now, we're only able to support category filtering for English, French, German, and Spanish. 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.
You can block ads from up to five of the following categories:

• Cosmetic procedures and surgery: Includes lifts, suctions, lasers, hair removal and restoration, tattoos and body modification.
• Dating: Includes dating services and online dating communities.
• Drugs and supplements: Includes pharmaceuticals, vitamins, supplements and related retailers; does not include resources providing information about drugs.
• Get rich quick: Schemes promising fast earning.
• Politics: Includes politics or controversial social issues; does not include ads for news organisations that are not generally associated with a partisan viewpoint on issues.
• Religion: Includes religious ads and ads advocating for or against religious views; does not include astrology or non-denominational spirituality.
• Ringtones and downloadables: Mobile add-ons including ringtones and other downloadable goodies such as screensavers and wallpapers for desktop PCs and profile layouts and graphics for social networks.
• Sexual and reproductive health: Includes sexual function and fertility ads; does not include normal pregnancy resources.
• Sexually suggestive: Provocative pictures and text.
• Video games (casual and online): Includes video games, online games and downloadable games; does not include video game consoles.
• Weight loss: Includes weight loss, dieting and related products and programmes; doesn't include healthy eating or general fitness ads.
