Yahoo! Dominates -- Excite Falters; WebSideStory's StatMarket.com Reports Top Ten List for Search Engine Referrals.

SAN DIEGO--(BUSINESS WIRE)--Sept. 1, 1999--

WebSideStory(R) (http://www.websidestory.com), the leader in Internet tracking and traffic analysis, today reported that Yahoo! (NASDAQ: YHOO) accounts for 43.55% of all search engine referrals. This marks a 7% increase since January 1999. Conversely, market share is down 60% for Excite in the same period and it now accounts for less than 10% of referrals. This information and more is published at WebSideStory's StatMarket.com (http://www.statmarket.com), the industry's most accurate source of data on Internet user trends.

StatMarket.com information is gathered in real time from more than 35,000,000 unique daily visitors to more than 130,000 Web sites using WebSideStory's HitBOX(R) Web traffic analysis technology.

Excite search engine referrals fell from approximately 24% in Q1 1999 to 9.85% on August 29, 1999. The decline of Excite-based search referrals may be linked to the June 14th agreement between America Online (NASDAQ: AOL) and Inktomi (NASDAQ: INKT), which replaced Excite-powered Netfind searches with the Inktomi search engine.

"This kind of market information is only available at StatMarket.com," said Blaise Barrelet, president and CEO of WebSideStory. "Only by tracking traffic to so many sites all over the Web can you accurately measure referring search engines."

The top ten referring search engines on August 29, 1999 were: -0-
