Goto.com was an Idealab spin off and was the first company to successfully provide a pay-for-placement search service.[1][2][3]
In February 1998, GoTo offered advertisers the option of bidding on how much they would be willing to pay to appear at the top of results in response to specific searches. The bid amount was paid by the advertiser to Goto every time a searcher clicked on a link to the advertiser's website. By July 1998, advertisers were paying anything up to a dollar per click.

GoTo's business model was based on the idea that its paid listings would make it more relevant than other services, especially for general searches, and web sites that pay more are probably better sites. A similar service had been offered by Open Text in 1996, but this precipitated outcries and bad publicity because searchers at the time did not want the search process more commercialized.

In contrast, GoTo's pay-for-placement model was very successful. Commentors theorised that the web had matured in the intervening two years, and these type of economic models were more acceptable since the web was no longer just a place for academic research, but also a place for buying products. GoTo founder Bill Gross speculated at the launch that GoTo would succeed because, as a relatively new service, it had no reputation to taint with paid listings, unlike Open Text.

On October 8, 2001, Goto.com, Inc. renamed itself Overture Services, Inc.[4] GoTo's chief operating officer Jaynie Studenmund said "We also felt it was a sophisticated enough name, in case our products expand."

Through partnerships, Overture enabled portals such as MSN and Yahoo! to monetize the hundreds of millions of web searches made each day on their sites. Indeed, these partnerships proved highly lucrative, and in a period otherwise marked by dot-com failures, Overture became a substantial profit driver for portals like Yahoo![5]

This success enabled Overture to acquire web sites such as AltaVista and AlltheWeb.[6]
