AdWords

AdWords is Google's branded P4P service. This offering classifies Google as part Pay per click (PPC) Search engine. The service places relevant text-based ads both within Google, termed "sponsored links", and on external sites willing to host Google ads, termed "Ads By Google." These external sites are those that use AdSense, the other side of the Google advertising model. Companies wishing to promote their products or services can enroll in this program. The biggest competitors are Espotting, and Overture owned by Yahoo!.

The service has generated lawsuits in the area of trademark law. Several lawsuits [1] are apparently pending over trademark infringement.

Interacting With Adwords

On the Google site, the Ads are pure text, and thus difficult to block. However, on external sites, they are hosted within an IFRAME tag, making them easy to remove with advertisement blockers like the Mozilla extension Adblock.
