I own http://www.stupiddrivers.net/ and have adsense on it. The ads are usually good, but 20-30% of the time they are on the wrong topic. Is there a way to for adsense to focus on only specific ads?
last time there was a way from adsense to drive more specific ads on your site by insert some code. but last few months, i heard adsense already changed the way of ad delivery. seems it is based on your visitors, not the site content.
Inorder to get relevant ads, you could try- 1. Section Targeting - This method is to place special keywords between the most relevant content on a webpage. Google then, will use this content specificall to deliver more targeted ads. 2. Competitive URL filtering - to filter out urls from which ads are displaying in your site.
You can use Adsense Ads preview tool to do this. See HERE. It also gives you the facility to check which Ads will be shown to a user coming from different countries.
