Quickly and inexpensively get workers at Amazon’s Mechanical Turk to provide written answers to questions about what they think about your site. It costs $10 for 10 reviews.
You could go to Mechanical Turk (mturk.com) directly and save a little money but FeedbackArmy is easier and still very inexpensive. The quality of responses varies dramatically, so you won’t necessarily get 10 helpful reviews for your $10. The advantage here is that you can get a higher quantity of responses — look for repetitive feedback. This is a bit more quantitative approach than watching a video of each user where you might find problems that even the user doesn’t realize they are uncovering. FeedbackArmy has two similar competitors, EasyUsability.com and 3rdPartyFeedback.com.
