Local review site Yelp is not going to sit around and let competitor CitySearch have even a day to celebrate their new beta launch.

CEO Jeremy Stopellman, noticing our Comscore comparison of the services – “According to comScore, Citysearch brought in 14.6 million unique visitors in the U.S in October, compared to 143 million uniques across its ad network. (Yelp, by the way, did 6 million uniques)” – emailed us with some of their internal traffic numbers and stats.

Yelp’s Google Analytics stats for the past thirty days show 15.8 million unique visitors, way above the six million Comscore records. And Yelp also shows other interesting stats in the chart below: 4 million reviews, with 34% restaurants, 23% shopping, 8% beauty and fitness, etc. Users are 51% male and 49% female, and 65% have a college degree.

Not bad for a company that was born just four years ago.
