What this category is really about

Automated tests confirm the product does what you built. Usability testing tells you whether what you built makes sense, which is a different and usually more expensive question to get wrong.

Two modes. Moderated sessions are live interviews — high signal, roughly an hour each, best for exploratory questions. Unmoderated tests send a task to a panel and return recordings within hours — cheaper, scalable, best for comparative questions where you already know what to ask.

Panel quality is what you are really buying at the top of this market. Recruiting eight cardiologists is a genuinely hard problem; recruiting eight people who own a smartphone is not, and the price difference reflects that.

What to evaluate

Panel reach and screening

Can they find your actual users? Screener quality determines whether findings generalise.

Moderated vs. unmoderated

Most teams need both. Check whether the plan covers both or charges separately.

Analysis tooling

Transcripts, tagging, highlight reels. Without them, twelve hours of video never gets watched.

Incentive handling

Whether participant payment is included or a separate operational burden on you.

Common mistakes

Testing with five people who all work at your company.
Leading tasks that tell the participant what to do, so you measure instruction-following.
Collecting recordings nobody watches. Budget analysis time equal to session time.
Running a usability test to settle an argument that a five-minute A/B test would answer.
