just registered onto woopra' site ... so what i need is only their code?

Yeah. Once they give your site the a code, just enter it in the settings, and you should off and running. :)

How does this measure up to Google Analytics?

OK, so i'm waiting ... :D

Data that is gathered is complied live compared to Google Analytics and Quantcast where you have to wait after a certain time to see your results. You can't also actively track to see where users are going in your site (forum in our case) in and out and their patterns.

When I am logged in I can watch one user go from the main page, reply to a post, read a thread and go off to another site, then come right back and do something else. It's really something else. Once I get a code for another one of my sites, it's going to help a lot because the site is so huge I want to be able to see how people navigate around the site, as most of them are visitors.

Like my Ex GF says: 'Answer me the question!' :P

Who's better, Google Analytics or Woopra?

I can't say. That's a personal option. I have never used Google Analytics.

I saw this, and I feel in love because I love the details. I contacted the dev team right after my initial creation and they were like... "Send our way now! Thanks!". Now I got them in my Google Talk contacts. Originally this was designed to be used on a WordPress installation. Course.. it's designed for any site. All you really have to do is add the code, and this plugin, makes it simple to do that. :)

does it spider your site,too ? like google ? i mean, is it good for more traffic and search engine hits ?

I don't think so. It gathers data based off them visiting the site. I can really care less where the spiders go. I haven't seen any popup, so I doubt they are being tracked.

interesting :D
