AdSense is an online advertising program that is operated by Google.
The program is designed to be used by publishers in the Google Network of content sites in order to serve automatic text, image, video, or other forms of media in the form of adverts.
The idea is to target audiences based on the site content. The adverts themselves are administered, sorted, and maintained by Google and are capable of generating revenue on a per-click or per-impression basis.
The program is available for publishers in the Google Display Network who display advertising based on their keyword lists. This results in advertising relevant to the publishers’ website.
How does AdSense work?
First released in March 2003 under the name of Content Targeting Advertising, Google applied the name AdSense as a way of following up Applied Semantics from 1998, which was a rival offering.
The name was taken over when Google acquired Applied Semantics in 2003.
AdSense operates by a user inserting a specific AdSense Java Script into a webpage. Web cookies ensure that the website remembers particular key information which will be associated with the adverts.
