How ads are targeted to your site
Google automatically delivers ads that are targeted to your content or audience. We do this in several ways:
- Contextual targeting
Our technology uses such factors as keyword analysis, word frequency, font size and the overall link structure of the web in order to determine what a web page is about and precisely match Google ads to each page.
- Placement targeting
With placement targeting, advertisers choose specific ad placements or subsections of publisher websites, on which to run their ads. Ads that are placement-targeted may not be precisely related to the content of a page, but are hand-picked by advertisers who've determined a match between what your users are interested in and what they have to offer.
- Personalised targeting
Personalised advertising enables advertisers to reach users based on their interests, demographics (e.g. "sports enthusiasts") and other criteria. To opt out of personalised advertising, users can change their controls in Ads Settings.Personalised targeting type reports may include contextual targeting when user data, such as cookie ID, isn’t available. If you’ve selected “Non-personalised ads” in your EU user control settings, you might still see ads under the "Personalised" targeting type even though user data isn’t being used.
- Run of Network targeting
Run of Network lets advertisers target all sites in the AdSense network, except explicitly excluded sites, according to available inventory.
