If you have pages and pages of articles on a certain topic, such as "Internet Marketing" then the ads shown will be all be related to that topic.
Your webpages should contain keyword related to internet marketing such as "email marketing", "Adsense", "ebooks", "web traffic", "affiliate programs" etc…
Therefore the visitor on your website will likely click on the ads since they have an interest in them. Otherwise they wouldn't be reading your article in the first place.
