Contextual Advertising

published by on 28th February 2004 under Performance Media

Contextual advertising places in real time an ad on a page based on the specific content of that individual page. For example a publisher may have a sports channel and has traditionally sold this placement option with the same ad displayed on all pages in the sports channel. With contextual advertising an ad for tennis shoes would appear on pages about tennis events while an ad for golf clubs would appear on a page about golf events. With a news site this becomes even more powerful due the wide range of ever changing stories and topics covered by each page of the site.

Contexual advertising technologies have been around for a number of years but Googles AdSense program has made a real impact and is set to really shack up the online advertising industry now that AdSense can support image banners in addition to the traditional Google AdWords (text ads).

The Google AdSense program also places ads not only based on context but also on popularity of the ad (click through rate). This means that publishers maximize the return from there inventory by eliminating ads that perform badly and only presenting ads that are relevant to the content and popular with visitors. Advertisers are charged on a cost per click basis.

Overture also offers a contextual advertising technology called “Content Match”
