August 2008 Real Search Market Share per Quantcast

SEO digest

Disclaimer: SEO Theory is not associated with Quantcast.com and the SEO Theory real search market share report is an estimate based on data provided by Quantcast.com for free through its Web site. Quantcast.com has not endorsed this report. These traffic estimates may not represent actual unique visitor data.

Real search market share is measured in terms of estimated unique visitors rather than number of queries performed. Because of automated rank-checking tools (and manual rank checking), Google’s estimated search market share based on queries performed is heavily inflated and therefore an unreliable indicator of potential search traffic.

The following tables are based on Quantcast’s estimated unique U.S. visitors for the selected domains. Most of the domains listed here were included in the July 2008 Real Search Market Share report because Quantcast estimated a minimum of 100,000 visitors for each. Excite, Hotbot, Lycos, Mamma, and Netscape should have appeared on previous reports but were accidentally overlooked. In late July the July Data was adjusted to include several of the omitted search services. Gigablast has yet to qualify for inclusion in this report.

Beginning this month, percentage of market share is being included for Algorithmic search. The percentages are derived from the total estimated visitors included in the report and do not reflect actual market share (which would include many more search services that receive fewer than 100,000 visitors per month). The July percentages should not be compared to the August percentages because the July estimates do not include all the listed search services.

The report is divided into three tables: Algorithmic Search, Directory Search, and Blog Search.
