I believe I have a great idea, and want to test the market before I create a site for it. However, I'm having some difficulty with Google AdWords - I'm a total beginner with SEO/SEM.
When I plug in keywords into AdWords tool, I get no results at all, globally, unless I put it some very very broad keyword that aren't really related to my idea. I guess this means no one is searching for it? That very well can be. However, due to the unique nature of my idea, I believe people aren't searching for it because they don't know they can do something like that yet.
I know you definitely can do something like that - I just finished a proof of concept, so it's a valid idea that solves an actual problem. But, what to do if no one is searching for it? Once I make the site, how do I get visitors to it? Is organic link building my only road to success?
