Well, a mockup would have been my next step, if I had received a more positive response at this stage. However it became obvious right away, that my feature set was wrong and I had miss judged how big the market was. I think the ad-words are a good idea though. I'll have to keep this idea in mind for future projects. How 'obvious' do you think I should be on my landing page, that there is actually no product though? Do I just land to a big 'coming soon' sign, with a field for people to enter their e-mails? Or should I try and create a fully functional site and just say on the purchase page that the product is coming soon and allow people to leave their e-mail.
