What is the best "invisible" counter
 

Anyone know what is the best page stats counter that is invisible to page surfers?

I don't know about the best, simply because I haven't compared it around. But I use Stat Counter on my blog, and it is doing a decent job.

Is it for a blog, or non blog?

If it's for a blog, I love MyBlog log.. only $3 per month or $25 for the year..

I get clickable refering urls, which is good to land on the SE page that sent the traffic, to see where I rank for that keyword,.. it gives the query string, etc

It also ranks the outgoing links which tells me what the surfers like to click on, & it tells me how many clicks I send to who, etc...

Pretty fucking neat.. you can try the free version, but you only get the full features for 3 days..

extremetracking is invisible if you pay 5$ for it :)

Your server log.

Server Stats?

Yeah you can just look at your raw logs, or set up webalizer or something.
