How can I encourage participation in a survey?

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.

Surveys suck and nobody really likes to answer them, not even you.

If the "goal to establish that my product has market potential" then you might also need to consider other avenues to reach that critical objective. I imagine the reason you're wondering if there's a market for your product is that there's nothing on the market that looks like your product? If your product is a B2B offering, how difficult would it be to find 10 potential future buyers and sit down with them for 15-20 minutes? And if it's for consumers, how difficult would it be to find 30 random people to talk to by just walking into a Starbucks? Instead of focusing on quantity with a large-scale online survey, focus on the quality of the feedback: talk to a few people, in person. Tech is for what people can't do better. Good luck.

Free gifts always work in surveys , or use content locker for this purpose. User always do it.

Agree totally with frenchie Survey Sucks and Nobody Likes Them.

But I think you can give some user a prize and attract them to fill the survey. While promoting your product ad a line "Daily a lucky winner will get movie ticket( or any cheap prize)". For sure the response will improve. No one hates the free stuff.

Also I would suggest get some live user if your product is developed. Show them the product ask them to use it and take the live feedback. Talk to them directly.

But believe me that prize stuff will definitely work. Just put the keywords in the proper place and check it.

Offer free gift to some people who does the survey.

I think you really need to give us some more details if you want an effective answer.

Since you are putting a survey behind a Google ad, I will assume that you are interested in learning more about a particular segment of the world that is already searching for something. Since you are apparently not satisfied knowing just that they have clicked on the ad (validating that demand exists), I assume you want to know more details about who are the people who clicked on the ad. The people who clicked on the ad, presumably wanting a thing or service, are not interested in taking a survey.

I would propose, based on my assumptions, that you continue down the adwords campaign, but direct customers to a special landing page advertising the apparent product or service, offering a quote or pamphlet to potential customers who supply their phone number or email address, a common scenario in b2b SW sales. Having hopefully obtained some responses by having a more clear "what's in it for me" for the customer to leave some information, you can directly call these people to interview them and understand whatever it is you wanted to learn.

You should, by the way, have some sort of a pamphlet/offering to back this up. These people may become your earlyvangelists, and you don't want to violate their trust and alienate them this early in the process! During or after your interview, disclose the fact that your product is not ready to launch, and you can give them a pamphlet describing your current plans and intentions and ask them for feedback. If they ask you how soon they can buy it then you know you've got a winner.

Why don't you try Amazon Mechanical Turk? It's very often used for surveys. Here's are some links of people using it for surveys.
