Whether to improve relevancy with their content or to keep competitors from advertising on their pages, publishers want control over the types of ads that can run on their sites. Google announced Tuesday that it is expanding the capability for publishers to opt out of certain ad categories and has increased the number of categories and subcategories from 250 to 470. More detailed subcategories give publishers greater refinement in blocking ads on their sites. For example, instead of blocking the category “Apparel,” you can now pick any of the new subcategories, “Sunglasses,” “Handbags” or “Watches.” The feature is now available in all AdSense markets and supports Chinese (simplified), Dutch, Polish, Russian and Turkish, in addition to English.
