Google, Yahoo, Microsoft Market Share Report, September 2007

google yahoo microsoft paid search share september 2007 Across our client base, paid search market share across the Big Three Engines held relatively stable in September. (Click on the graph to left to enlarge.) Yahoo picked up one point of share from Google. It has been about five months since Yahoo showed an increase in share. Of course, such a small one-month up-tick could be random noise. It will be interesting to see how Yahoo performs in October. And the real story, of course, is coming shortly as we enter the all-critical holiday period. Our firm has been growing year-to-date, so total client ad spend under management is up in absolute dollars. These share numbers reflect the proportions of those dollars going to G, Y, and M. As mentioned before, nearly all of our clients tell us to run their paid search campaigns to economic target. None of our clients set a priori budget levels by engine. Our portfolio bidding technology optimizes ad spend, buying the highest quality clicks first. Thus, an increase in ad spend on one engine, relative to the others, reflects an increase in click quality relative to the others.
