Bid simulator and more transparency in Google's ad auction
As part of our continuing effort to give advertisers more transparency about Google's advertising system and how our ad auction works, we're launching a cool new feature in our AdWords system called the bid simulator.
The bid simulator gives advertisers more information about the potential impact of their bid on their advertising results, allowing them to make more informed bidding decisions. For each potential cost per click that an advertiser could bid, the bid simulator estimates the likely number of ad impressions, how many clicks an ad could have gotten for those impressions, and how much those clicks could have cost the advertiser.
