Usability Testing
A foundational UX research method systematically popularized by Jakob Nielsen and others in the 1990s. Its core approach involves having real users independently complete tasks while observers record points of confusion and failure. Research indicates that testing five users is sufficient to expose approximately 85% of usability problems.

Having users use the product in person exposes friction points that appear only as "churn" in backend logs; a scale of 5 people is enough to surface most common problems early, without waiting for dozens of users before acting.
The author argues that in usability testing, page views and signup conversions are both proxy metrics and cannot replace direct evidence that 'the AI representative produced a useful answer' or that 'the visitor successfully reached the owner'.
The author suggests stratifying the statistics of test results by depth of behavior: the comprehension layer (whether visitors understand the purpose of the AI representative), the accuracy layer (whether answers are faithful to baseline facts), the reachability layer (whether visitors can bypass the AI to reach a human), and the trust layer (whether freelancers are willing to proactively share it with clients).
Paid testing is essentially an extension of usability testing from the product interface to the documentation level.
Usability Testing is a classic UX methodology that was systematically popularized by Jakob Nielsen and others in the 1990s.
The basic principle of usability testing is to have real users independently complete tasks in front of an observer, with the observer providing no guidance or explanation and only recording points of confusion and failure.
