Counters are popular among web developers. They are used to count the number of visitors (or hits) for a particular page or for an overall web site. We can create an attractive graphical counter like the one below or a hidden one with the value being sent to the owner by email. A judicious use of counter in different pages will help the designer to improve the site.
If more visitors are visiting the help section then some more details are to be provided in pages for the visitors. Which is the most popular section in your site? How much you should charge for an advertisement in your page? An answer to all this and many more is to use counters.
