Since they have visibility into the overall keyword bidding environment, Google could take advantage of expected bid vs. actual cpc relationships for different positions in ways that no external optimization system could, but such a system would not serve to maximize their own revenue. Does Google provide transparency into the actual bids they are pushing up? Brava_seo, why did you decide to turn it off so quickly?
I've looked through the docs, and was hoping to get some insight from someone who's tested this.
