Redirect link PhP

Hello community!
I am new around here, I am seeking assistance with php help.. I know diddly squat about PhP but would love to learn on making something simple but affect for my community.

I sell products on many sites, however I would love to make a redirect link instead of just my normal web address "example.com" to something like this "example.com/redirect-AD.php"
What this will do is store the amount of clicks that link has had within that php file or somewhere else.

Example of what I am looking for:
Potential customer on X site views my product, clicks link from an image "example.com/redirect-AD.php"
> I can then see somewhere within that .php script that that persific address has got any clicks, with this information I can see if it is worth advertising there again.

Hope I explained it right!
Thanks in advance. :)
