Overture's Search Term Suggestion Tool gives you the number of searches performed on specific search terms on Overture and their partners. But how to figure this for Google? Google's AdWords estimates don't give you this answer.
Google says they do a total of 200 million searches per day. If Overture and partners did about the same, then we could just figure that the numbers from the Overture Search Term Suggestion Tool would also be a good indication of how many searches were done on Google.
Anyone know how many total searches per day on Overture and their partners?
Here's one way to figure out how many searches on a particular term on Google.
Google says they do 200 million searches per day.
Overture (according to SE Watch) does 167 million searches per day.
So use the Overture Search Suggestion Tool to see how many searches are performed on Overture for a particular term and add 20% to get your Google number.
That should be pretty close.
So, for your AdWords search terms, add 20% to Overture's Search Term Suggestion Tool numbers and add 50% for regular search results listings.
These are ballpark figures of course. And yes, this is all based on numbers that Google and Overture are providing, so they both may inflate their numbers for promotional purposes. But, maybe they both inflate at about the same rate, so Google may be 20% or 50% more than Overture, but actual numbers for both may be lower.
My gut feeling is that Google still provides a much higher number of searches than does Over - certainly more than 17% as indicated by the published search numbers above.
For the correct Spanish name of our region (used by all language searchers) we had a combined total of 10 CT on 115 searches in 1st place. For this term in AdWords in average 3rd place we had 20 CT on 1267 searches.
Now it gets interesting. For the English translation of our region on Overture (3rd place) we had 12 CT on 667 searches. For this term in AdWords (between 2 & 3) we had 12 CT on 264 searches.
Don't know how to explain it. Not that I wouldn't guess that the English term wouldn't get a lot less inquiries than the Spanish one. But how does Over get 3 times more searches than Google for this term? Hmmmmm..
