Bidding
Bidding means placing a bid price that you are willing to pay as an advertiser on a pay-per-click search engine. The highest bid for a given keyword achieves the top spot in the PPC search results. In Overture, the top three bids are "featured" on Overture's partners' sites, including AOL, Altavista, Infospace, and others. The minimum bid amount on Overture is 5 cents per clickthrough.
