I found a site which is pretty correct...my page views were aprroximately correct, so was my revenue, idk abt the worth tho, cuz no tool can calculate the worth... Here it is: http://www.valuatemysite.com
I have 8 sites. I tried 2 of them. One that makes 350$ a month was worth 569$. The other one makes 100$ a month and it was worth 1500$. *aHem*
Like i said guys, Worth can never be estimated by bots... as for the other things, like impressions and revenue, its almost correct so you can use that to check other sites...
You should really guide for these sites. It's always much better to do the evaluation yourself or get a professional to do it.
