comScore Ranks August’s Top 50 Web Sites

Media analysis firm comScore has released its site rankings for August, with Yahoo, Google, Time Warner, and Microsoft nabbing the top four slots.

Media analysis firm comScore has released its Web site traffic figures for August 2007, and finds that, in terms of U.S. consumers, sites run by Yahoo, Google, Time Warner (e.g. AOL), and Microsoft occupied the top four positions during the month, scoring the largest numbers of unique visitors.

Although comScore’s rankings for August don’t reflect any changes from previous months, the company noted several seasonal variations in Web traffic, including upticks of traffic to education-related sites like college resource site FastWeb, the College Board, and education-related information sites like Dictionary.com and Answers.com. The start of fall sports (and football season) also drove traffic to sports-related sites, a large number of lottery jackpots propelled lottery traffic, and Viacom’s Comedy Central’s “Indecision 2008″ coverage apparently propelled traffic to a broad range of comedy sites.

In terms of “ad focus,” comScore finds advertising.com is still the top ad networking, reaching 89 percent of an estimated 181 million online Americans. ValuClck, Yahoo, Google Ad Network, and Tribal Fusion rounded out the top five ad focus scores, although there’s not a tremendous variation in the reach of the second-ranked site compared to the fifth, and they all trail advertising.com significantly.
