It used to be that alexa was the only free ranking system in town. Unfortunately alexa is skewed and manipulated beyond belief. I found a new service called compete.com a few months ago and it has changed a lot since then. In the last little while it has got super useful as they have added things like number of unique visitors to the site per month, average pageviews and average session time.
Compete.com currently only tracks traffic in the USA.
|Unique||Pageviews/session||Avg Session time|
To see for your self check out compete.com you can also click on the pageviews tab to get a trend of pageviews over the last year or session time.
I have asked them to dig a little deeper into the data and give a break down of monthly logins of dating sites. This is something the industry desperately needs a ranking based on USER ACTIVITY and we all know how much the useless “unique visitors” number from comscore, nielson and others are quoted.
I will post the numbers when they send them to me next week. No doubt compete numbers will be extensively quoted in the media :). Ranking sites based on user activity will certinately spark a PR war.
