In 1998, two Stanford students, Sergey Brin and Larry Page believed that they could create a search engine that based its results on the relationships between Websites relevant to what the user is searching for. This was an improvement over existing methods at the time. The number of times the keywords appeared on the Web page was the over-riding factor. Another factor, however, was any back links the Web page had which was a system known as Backrub.
Google Adwords came in to light in 2000. It was their advertising model. They offered to establish and maintain and advertising campaign for their client for a monthly fee. Adwords has the ability to estimate the cost per click for a particular keyword. The fact that the adverts are text-based give the page a clean look makes the page load quickly without having to download any fancy graphics. It also created a loyal following with those who use the search engine.

They do admit that the algorithms they use are based around back links.
