I saw a very similar article by 'Dr David Smith' who effectively stated that nobody used traditional search engines while everybody used overture. ie that if you wanted a result you had to pay to be at the top of overture.

I use any search engine I can get onto and can compare results from same search terms used to find the same page on both Google and Overture. Eg, for a three word 'business' search term I am 6th place on Google, Overture 1st place).

Over the course of this year I have had almost 200 times the visitors through Google.com as I have had from overture! And that excludes the regional Google and Yahoo searches!

Incidentally, msn.com yealds about 100 times more responses than overture for that search term.

Where the term is more generic, the ratio declines, however comparing all visitors between Google and overture I show a 200 to one comparison.
