I am about to do a customer development survey, which will be promoted either via AdWords or via an email campaign (maybe both).
I did a few tests with AdWords ads and it seems like responses level is below what I anticipated. I am assuming this is because when people click link to the survey, they do not see what's in it for them to answer my 10 questions.
But because this is only a customer development survey with a goal to establish that my product has market potential, and because I am on a budget, I can't offer people who click anything in return immediately.
I said that if they reply, and leave their email, they will receive an alert once (if) the product is about to hit the retailers, to get it at a low promo price. But this seems to be too indefinite. And it really is, because there is no guarantee that survey will prove that the product can be marketed, and that it will ever be manufactured.
Also I was thinking I might use some cause to encourage participation, e.g. "help the community of whatever by participating in this survey" but this sounds even more weak and not real.
I would appreciate any constructive ideas.
