I occasionally run into charts of search engine market share from Nielsen, like this one, or from other expensive services like Comscore.
Is it just me, or are these charts a bit goofy? Does Yahoo really still have 23% of the search market? Is Google at less than half the search market?
I don't believe it. Any webmaster will tell you that Google represents almost ALL of the search engine traffic. Yahoo is nowhere near 23%. Just read the blogs, here, here, here and here and on countless other blogs.
So I decided to poke around Alexa's stats and generate my own search engine market share graph. According to my calcs, Google is at almost 85% market share. Yahoo is at 9%. This seems to mirror what I expected.
I'm not sure why the premier (read: expensive) services don't match what everybody sees in their logs...
What do you see in your logs?
Some notes about my calculations:
I am counting reach, not pageviews. I didn't count any international domains like yahoo.co.jp or google.de, etc. For Google I only counted google.com and none of the subdomains like mail.google.com and images.google.com. For Yahoo I only counted search.yahoo.com. For MSN I only counted search.msn.com. For ask I only counted ask.com and search.ask.com. For AOL I only counted search.aol.com. For MyWay I only counted mysearch.myway.com and search.myway.com.
