[...] im going to keep this page print out to see if they are accurate in their guesitmates.
and in reply:
[...] these are just estimates. The tool has no way of knowing how good/bad your ad is.
Both of LucidSW's points here are absolutely key. To expand on each one just a bit:
* You are getting traffic estimates designed to help you set things up so that you can then see what really happens when the ads run in the real world - in which things can change from one second to the next. As an active account manager, you would want to watch what happens and make appropriate adjustments - early and often.
* To truly estimate how many clicks you will get would require that the tool would know things that it can not possibly know - and which have not even happened yet - such as how well targeted your ads are to the kewyord for which you are getting an estimate. And, as LucidSW says, how well written the ad is.
On one hand, a perfectly targeted ad/keyword combination tied to a perfectly written and compelling ad will likely beat the estimate.
On the other hand a poorly targeted ad/kewyord combination tied to a poorly written and off-putting ad will likely come no where near the estimate.
The estimator can know none of these things - nor even have the slightest sense of them - because the ads have not even been written yet.
