I am in need of a links-clicked tracker. I cannot find an existing module that does that specifically. I don't need to track ads, all I need is to log relevant data every time a user clicks on a link within my site.

Since I cannot find a module (please share if you know of one) I am developing my own module. I will use AJAX and Javascript to communicate from the client side.

The module does not need a block and I am not sure which hook to use in the .module when calling the function:
drupal_add_js( ... );

Any ideas?

Cheers and thanks much!
