A bid adjustment of -90% reduces the bid by 90%, to 10% of the original bid. Likewise, +900% increases the location bid to ten times the original amount. For example, suppose your ad group bid is $2.00, and the targeted location has a bid adjustment of +200%. The bid used for that location will be $6.00.
