Did you added analytics code to your site..? If so.. just sign into your account and click 'View stats'.
Sign into google analytics, get the code and paste it in your site and start tracking your site. Alternatively statcounter is available to check your site traffic.
Thanks everybody ,,,dumb question ,,, will it pick from when my site was published or just when it was installed?
You need to sign on for Google analytics and add the code to your site. You can also used the stats that comes with your web hosting package. You can used it from your hosting control panel. Cheers
Like everybody says, google analytic or stat counter. If your using wordpress, there are some plugins you could use like wassup or statpress.
cPanel hosts comewith AWstats I think. You can check your stats with detail there. It's very accurate.
First of add create a profile for domain name then add the code at the end of each of your webpage before body tag then check the stats.
