There are a few web-tracking companies out there, most of them don't exactly agree on which sites are ranked highest or how many visitors they get. Indeed, you only have to look at compete's claim that imeem was the most popular internet music site to see the complaints from other sites on the list pointing at other sites to question imeem's claim to the top spot. Jed Carlson from Reverbnation posted to Wired's music blog pointing out that Quantcast's network tracking showed his site had almost 20 million users - roughly the total of compete's measure of imeem and yahoo together. Of course, some other smart bod pointed out that Quantcast's network score for imeem was almost 40million users.
Regardless I wondered what each of these tracking sites would say about each other, on Alexa you can't ask for stats on Alexa, but compete and quantcast have now such limits.
Compere shows Quantcast in first place and alexa in last.
Alexa shows both compete and quantcast have about 2/3 of their visits from the US, and again Quantcast is the more popular of the two ranking #1134 vs compete's rank of #3691.
But Quantcast is the site that offers the greatest riches in terms of audience details.
Alexa.com (Rank 3,460) is a top 5,000 site that reaches over 745K U.S. monthly uniques. The site attracts a slightly male slanted crowd. The typical visitor reads Techcrunch and watches Al Jazeera.
Compete.com (Rank 9,101) Compete.com is a top 10,000 site that reaches over 263K U.S. monthly uniques. The site appeals to a slightly male slanted crowd.The typical visitor reads Techcrunch and buys from notebookreview.com.
Quantcast.com (Rank 899) Neatly removes any demographic information, nothing to see here, move along.
All 3 sites point to quantcast having the biggest audience, but quantcast and compete both disagree as to which site is in second place.
There are other sites which do this, but many of them provide only limited data to free users, Hitwise, Comscore, Nielsen etc I can't get data from these sites but here's what quantcast says....
comscore.com (Rank 146,251) This site reaches approximately 10,512 U.S. monthly uniques. The site caters to a slightly female slanted, more educated audience.The typical visitor reads Business Week.
hitwise.com (Rank 101,681) This site reaches approximately 16,467 U.S. monthly uniques. The site appeals to a more educated, very slightly male biased following.The typical visitor reads thinkprogress.org and uses ultimatefares.com.
Apparently conservatives prefer comscore while liberal minded people prefer hitwise.
