How would you validate a Busan cheap-meal map with hostels and students?

I’m running a six-week Busan-first experiment for Fooglemap, a live map of affordable local meals.

One current example is 10 handmade dumplings for KRW 4,000 in Sasang-gu. The listing includes map/directions value and was last checked on 2026-04-29. Coverage is still thin and prices can change, so I’m not treating pin count as success.

I’m trying to learn which distribution loop would produce real use: hostel or guesthouse referrals, university international communities, small travel creators, or restaurant corrections.

If you had to validate one channel first, what behavior would you measure: map opens, directions clicks, corrections, shares, or repeat visits?
