According to PC Data Online, Blue Mountain Arts showed a 25 percent increase in traffic for October, rising to 21st place from 29th place, with 9.7 million unique users.
As previously reported, Excite@Home paid about $780 million to buy Blue Mountain, largely to boost traffic. And AmericanGreetings.com and Egreetings Networks are planning to go public. Hurdles remain, however--notably making the sites' profitable. In addition, competition is becoming more intense.
"As a category leader, [Blue Mountain's] unique user numbers give us a good indication of what the total market size is and how it's growing," Sean Wargo, Internet analyst for PC Data, said in a statement.
Online sweepstakes sites also are showing strong traffic growth, the survey said.
The top five sites, in order, were: Yahoo, Microsoft Network, America Online, Geocities, and Microsoft.
PC Data compiles its information by tracking "unique visitors" and "unique buyers" on each Web site. Every visitor is counted once, no matter how many times he or she visits or buys from the site. PC Data said its survey included 80,000 Internet users.
