AOL, Yahoo! and Google rule comScore

comScore has released its TOP 50 Web rankings for October 2007, and Time Warner Inc. (NYSE: TWX) still has an impressive place there.

This gives the following breakdown for total unique visitors out of an estimated 182,206,000 users in the United States:

Yahoo Inc. (NASDAQ: YHOO): 136,775,000
Google Inc. (NASDAQ: GOOG): 131,639,000
Time Warner Network: 121,130,000
Microsoft Corporation (NASDAQ: MSFT) Network: 120,502,000

But there is one phenomenal property here: AOL's Advertising.com platform showed an entire reach of 159,204,000. That is roughly an 87% reach of the estimated 182+ million users in the U.S. measured by comScore.

The thing to watch is that ALL ratings and measurement companies give different data. comScore's data is based on a global cross-section of more than 2 million consumers who have given comScore permission to confidentially capture their browsing and transaction behavior. That means there can always be some slippage and mis-measurements, but this still gives a decent ballpark figure of web usage and web reach.

If you look at the data, this also bodes well for Jim Cramer & Co. over at TheStreet.com, Inc. (NASDAQ: TSCM). The financial web site owner showed a 125% gain in unique visitors with a 125% gain to more than 8.9 million unique visitors.
