I haven't done much with CPA, but I'm a member of a network and just applied to a specific merchant. Under their terms and conditions it says, "Search and PPC are not allowed." I understand that for some reason they don't want you to use PPC. But what do they mean by "search?" If you aren't going to use some kind of search engine optimization and you can't use PPC, how else can you promote the offer? They allow certain kinds of email marketing, so could they mean this is the only permitted way to promote their offer? This would seem strange, but I'm not familiar with these offers. I'm just wondering if they mean something else by "search."
