In my quest to create an MVP, I have created a one page landing page to validate an idea for a web application I had for a while, as well as gather input and leads from potential customers.
This was a quick and dirty job. I used Unbounce.com to get up and running, registered the domain and created two page variants myself in a few hours. All of the design was done by me (I'm a programmer, not the world's best designer). After putting it online I set up an AdWords campaign with some medium to low bids on very specific keywords.
And then, nothing. I have gotten quite a few page views, but only three leads that filled in the beta sign in form.
Now my question is, how far do I continue with this idea? I think it might be a good idea, and I'm not sure if the lack of interest is due to marketing not being so good or there actually not being a market for it. Should I abandon it completely and try something different, or should I follow my gut and try and work on the landing page more, do more A/B testing and maybe invest more money in the AdWords campaign?
At what point in this MVP business does one consider an idea to be 'invalidated' and abandon it?
