Hello, I have noticed that adsense show ads which aren't reltaed to my website , I wonder if that could happen if the template include sth related to these ads ... and that only happen in the main page see http://www.languagewiki.info/ it is a language community , although the ads not related meanwhile you entered any page you will see the proper ads to the keywords of the site Any one has clues
Google will show ads based on what they crawl. So look at your site from a crawl bot perspective. Seed keywords that will help them determine your content. Google will also show less relevant ads on sites where there are few advertisers. And Google will show less relevant ads on sites that are not very authoritative. Finally the ads you see are NOT the same as the ads your visitors will see because Google uses both cookie and IP tracking.
thank you so much, your reply is really informative to me ,,, But it shows related ads in the other pages that's why I am wondering
