This is a interesting list of services for user testing. I was surprised at how cheap and quick they sound; it made me think “Why wouldn’t you do this on every client project?”.
“Usability and user experience testing is vital to creating a successful website, and only more so if it’s an e-commerce website, a complex app or another website for which there’s a definite ROI. And running your own user tests to find out how users are interacting with your website and where problems might arise is completely possible.
But using one of the many existing tools and services for user testing is a lot easier than creating your own. Free, freemium and premium tools are out there, with options for most budgets. The important thing is to find a tool or service that works for your website and then use it to gather real-world data on what works and what doesn’t, rather than relying purely on instinct or abstract theories.”
