Stu, some friendly advice. Lose the adverts. You arent going to get enough traffic for a few months to make it worthwhile, and quite frankly at this stage you're just going to put people off.
If you want to pull in users, make it advert free and then get in a few later, once plenty are attracted to the service.
I thought you worked in online marketing once?
