General question, what other PPC company's use an ID like the way Google uses their pub-xxxxxxxx number to identify accounts ?
I don't understand exactly what you're asking for? ASE Adnet has a variable for account (var userid=xxx, but most networks have something like that.
I want to expand, my site share4gain so it can host many advertisers, provide they allow such methods. For instants google uses a pub-id number, and it covers all ads placed on a page, where as adbrite uses a zone code for each individual ad, so thats no use. The company @Aron Schatz mentioned, I never heard of it, so I'll assume very few have... so thats no use. I dont know about yahoo or msn as I cant sign up for those been in Europe. Anyway its not important just now.. I just thought all you PPC pros, would know of a few ad networks that operate like google.
