The #1 reason people will sign up for a service is curiousity. That is what sucked me into quantcast. There business model is interesting… they give you low score for your site… then you can “quantify” your statistics by adding there code to your site.
Here is the thing though…. There code has been hanging pages on my site for months randomly. I also notice it on other sites. Well it doesn’t even matter cause i looked at “quantified” numbers for my site today:
ok 6800 uniq per month? what? Its not like its alexa and you guys have some tool bar estimator. I have your code on my website.
Oh ya I also have another companies code on my site called google analytics and it reported a little more accurately:
Hmm google says last month (sept) this site had 180,000 absolute unique visitors.
Anyway the quantcast numbers never changed since I installed the code.
