Contextual advertising
Advertising on the Internet that is determined by content on the page the ad is being shown. The advertising company achieves this by using a spider or other script to scan the webpage for keywords based on the keywords available on that site and the advertisers available determines what ad is displayed on the page. Contextual advertising is more effective than generic advertising because it relates to what the visitor is reading instead of just randomly displaying an advertisement.
Computer Hope uses Google AdSense for its contextual advertising on its site, and it's likely that the advertisements shown on this page relate to Internet advertising.
