While the question you are asking is somewhat vague, I think I may be able to help.
When you want to store hits across your entire application in ASP.NET, you should use an application level variable. These work the same way as session variables except (you guessed it) they don't expire at the end of a session. They WILL however reset when the application is restarted/terminated.
If you do not care if the numbers reset upon an application restart, then use an application level variable. Attach an event handler to the click event of the linkbutton, button, or whatever button you choose to use that will increment the application variable by one. Here is a tutorial on application level variables:

If you DO care if the numbers reset upon an application restart (or if your application is going to be running on multiple servers) then you should take the same approach as previously mentioned but instead of using application state to store your value, use a database system to push/pull the variables.
Hope this helps
