How do Companies Find Stats on Your Site?

I tried to sign up for some big name companies in CJ, but I got shot down because they say my site is not popular enough.

Walmart on LinkShare is another example. They said I don't get enough traffic. How do they find this info out and is there a way for me to cheat this.

I need some more affiliates for my niche site.

have a look at compete*com and or alexa*com should give you information about your traffic... to be honest i dont see why its such a big deal for them not to let you post there ads surely some comission is better then now for them??

The place I use to find stats on peoples sites that are way beyond Alexa is...

Once you use it on a competitor of yours, it will be your new best friend.

I especially like the feature of it showing you all the other domains that are hosting on the same server as the domain you entered in.

Great for competitive intelligence.
