Question about estimated impression in new google keyword tool

It's about new keywords tool.

Don't know whether people noticed it or not, but there is a big difference between local monthly search volume (exact match) and estimated impresions.

I assume estimated impression is daily, but even I mutiple it by 30, they still have significant difference.

I tried to search answer through Google and adwords help forum, but no luck.

Would anybody lets me know what's the difference between them? I would guess monthly search volume is calculated based on all google network and estimated impression is purely for google search.

Estimated impression seems to be more accurate to me, as monthly search volume often gives me the inaccurate figures (I ran keywords to test)

Above on the right side, there is a link that says "About this data"

Estimated Statistics - Impressions, CTR, Clicks, Avg. CPC, Cost, Ad Position

If you enter a Max CPC and Daily Budget under Advanced Options, AdWords will estimate performance for your ad for the associated keywords. If you don't supply a Max CPC and Daily Budget for these estimates, AdWords will estimate your performance using a CPC that is predicted to always place your ad in positions 1-3 with an unlimited budget to capture all available impressions.


This still does not answer your question about discrepancy, but it does shed some (basic) light onto what's what.

Hi smallcompany.

I've read "about this data" for several times before I wrote this post.

But unfortunately, I don't really know the difference between them. (from their definitions)

Have you tried contacting Google and asking them?
