How Many Site Hits? Depends Who's Counting

How many people visited Style.com, the online home of Vogue and W
magazines, last month? Was it 421,000, or, more optimistically,
497,000? Or was the real number more than three times higher, perhaps
1.8 million?
The answer — which may be any, or none, of the above — is a critical
one for Condé Nast, which owns the site, and for companies like Ralph
Lauren, which pay to advertise there. Condé Nast's internal count (1.8
million) was much higher than the tally by ComScore (421,000) or
Nielsen/NetRatings (497,000), whose numbers are used to help set
advertising rates, and the discrepancies have created a good deal of
friction.
