I have frankly come to believe that the landing page only approach is a non-solution to validating the idea. In a landing page, you are testing how well you can convince visitors to contact you, signup or download a whitepaper. Real relationship with a customer start when he actually gets to try out the service you are offering. That is the real reason why trial -> paid conversions are usually low. In a landing page MVP, you are not validating your idea, you are validating your ability to convince for a particular idea. It is quite easy to get false positive or false negatives here. Rather, what I prefer is to get hold of people and email/call them to actually hear about their pain points. Old school but works like a charm.
