how can i find unique visitors visiting to my site?

i'm looking for such tools to get the information how many unique visitors are visiting my site this day

 

Check your stats in your cpanel or install google analytics.

 

hat depends on how your site records 'unique' visitors. Most likely it is via a cookie, and if you are using Internet Explorer, you would go to tools, internet options, and find the 'delete cookies' button (varies depending on the version of Internet Explorer).

Your site could also be seeing the IP address, the MAC code of the network card, possibly a combination of any of these.

Try deleting the cookies first. It is most likely to be the way the site recognizes you.
