If you only test one thing on Tinder, make it how far the free tier actually stretches.
I tested the site across two cities and the difference came down to whether the search actually respects what you set.
Provided how thin the pool gets outside big cities holds up, that one is a reasonable place to start.
What separates the platform from the rest of the field is how the match quality holds up past the first day.
Widening the radius on it added volume and quietly worsened how many profiles logged in this week.
What I would look at, in order, for Tinder:
- How much of Tinder is visible before it asks you to register
- How Tinder behaves on mobile data rather than wifi
- Whether the Tinder photos survive a reverse image search
