I have a client we have been doing PPC for and while the Brand is working so the account looks like it is doing well, but it is not. The other non brand and shopping are not performing. This site has a barrier to entry in that you have to have an edu/gov email address to even be able to buy (they are ecommerce selling office supplies and stuff that military bases and schools would use). I have tried targeting areas around military bases, education sector and a few other audiences. I do also have a competitor campaign going with little success. Any ideas on how to "get in" with this specific group.
