While there may be some dispute about the origins of the saying: “there are three kinds of lies, lies, damned lies and statistics” there is little disagreement about its general truthfulness. It seems particularly appropriate in regard to Yelp’s unique visitors.
Yesterday Yelp.com announced at SMX East that they had 38 million uniques on the desktop and it picqued my curiosity. Yelp.com has done a great job of generating reviews and adding value around them and I have been following them over the years as both a user and a professional, watching thier efforts to move from a niche restaurant site in the major markets to a broad based general site. Have they moved out of the niche and into the mainstream? Certainly 38 million uniques would indicate so.
But I was curious for some verification of Yelp’s numbers so I went to Quantcast, Compete and Comscore to see if I could independantly confrim them. The results, far from enlightening, illustrate the many ways that unique visitors can be counted.
