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. In June 1999, GoTo launched a tool set "direct traffic centre" (dtc) to enable advertisers access to keywords and real time bidding.
