What is the difference between All Hits and Unique Visits?
When you sign up (or edit your settings), you have the choice to have your counter increment on “All Hits” or “Unique Visits Only”. All hits counts every single hit the counter gets. So if a user comes back in 5 minutes, or keeps reloading your page, it will keep counting each hit. When you set it to Unique Visits Only, it will not count sequential hits from the same IP address. (An IP address is a unique identifier of a computer on the Internet.) So, if it is set on Unique Visits Only, the counter will only increment once if someone keeps reloading your page or visits multiple pages of your site that have the same counter installed. This user will not be counted again until someone else visits the site before their next return visit. (i.e. If someone returns to the site the next day or week, likely someone will have visited in between, so they will be counted again for that visit.) With typical traffic, the counter set to Unique Visits Only provides a good approximation of the number
