I need to ask users just one question on our website - namely "Did you find what you were looking for?" as an exit question.
This is just one question that requires a high confidence level of data i.e. 90% of users agreed that there are enough products on the site, 10% couldn't find what they were looking for etc.
How can I best ask this question to users to get a good response rate? Twitter? Qualaroo? (Expensive)? Build own questionnaire pop-up when users leave the site? What Users Do?
more information The website is an ecommerce site that sells a particular product. We believe that the lack of product range on the site is restrictive for users buying. Longer time spent on category pages and, indeed, switching from category to category certainly suggest this. But what we're asking for here is a little bit in-quantifiable. Don't you agree? (I could re-phrase the question to be more "how do I determine whether there is enough product range on my site" rather than provide an answer)
