Both bid amount and ad quality will determine an ad's rank in search results the week commencing July 23rd, 2007.

This will replace the current method, in which ads are ranked by bid amount only (bid-to-position).

This is designed to allow you to focus less on competitive bidding practices and more on the quality of your ads.

By improving the quality of your ads and making them more relevant to users, you may be rewarded with a better ranking and/or a lower cost for your ads.
