I'm working with a client that has Flash banner ads going on many publciations. We've got the generic click tag embedded into the banner for tracking purposes, no problem.
All the banners direct someone to a landing page. On that page, there are then three links to other sites this customer has.
We can obviously measure those click through with simple analytics and document referrer info.
However, what they liked to know, is when someone gets to one of the three final destination sites, which Flash banner did they originally click to get to the landing page. I don't think this can be done can it? My understanding is Flash banners can't carry any header info, etc.
Or, it seems like some kind of scripting the Online Media company would have to add, so something like a cookie would be attached to the user clicking through??? Any thoughts?
