Identify usability issues, improve the structure of your information, and generate more conversions.
A focus group is not a user test, and cannot identify usability issues.
For example, What does this organization do? or What does this product do? Additionally, because there is no interaction with the tester, test a lot of people at the same time.
Ask yourself, What is the problem? and base your research question on that.
Use eye tracking to help understand which element the user is talking about.
Record their desktop and webcam feed to capture facial expressions.
This can be great if the context of the experience is important. Guerrilla user testing is basically going to coffee shops or other public places and soliciting people to user test your product on the spot.
Evaluate the findability of topics on your website, and use this information to build better information flows.
For example, ask only simple, easy questions that are clear in the first 5 seconds, such as, What’s this company’s name? or What’s the price of this service?
