Google AdWords Traffic Estimator is Very Buggy

[pratishtha]

There are at least two instances where the Google AdWords Traffic Estimator provided estimates that could not possibly be correct, and were off by a very significant amount.

In one case bidding 0.05 resulting in a top 1-3 position, keeping everything else the same and raising the bid amount to 0.10 resulting in a 5-6 position.

In another instance restricting the geographic area to a 30 mile radius of Los Gatos California (thus defining Silicon Valley) derived the same cost per day as an unrestricted global whole Earth coverage.
