I've been given the wonderful job of setting up multiple pages and now i'm told they need to have sub id tracking. Here's my problem... I've got 4-5 directories with a single index php page with a redirect to the homepage as soon as someone goes to one of these pages. The purpose of the these pages (originally) were to track hits with g analytics to see what ad's worked best. NOW, they tell me they need to track these pages with sub id's. I have no idea what or how to do this. So it goes from being domain.com/ad1 to domain.com/ad1?=subid I can actually goto my site with the ?=subid but i'm not sure if it's working or not. Any help would be greatly appreciated.
