Everyone optimizing for the US App Store is fighting a wall built out of hundreds of ratings. Most of the map is not walled at all.
The number
Across the 19 storefronts in our measurement set, we looked at the median rating count of whichever app currently sits in first place for a tracked keyword. In 13 of the 19, that median is exactly zero.
Not "low." Zero. The app in first place, for a real search term, in that storefront, on the day we measured, had no ratings at all.
Norway, Taiwan, Russia, Mexico, Malaysia, Japan, Vietnam, Israel, Ukraine, Australia, South Korea, Indonesia, Thailand — thirteen storefronts where showing up with zero social proof is not a disadvantage, it's the norm at the top.
Why this matters more than it sounds
The standard playbook for a new app is: win your home market first, then localize outward. That plan implicitly assumes review count is a cost you pay once and reuse — build the wall at home, then go compete somewhere the wall is lower.
This data flips the ordering. If your home storefront is one of the six with a real wall (US, UK, and a handful of others), you're spending your most expensive months first and reaching your cheapest wins last — or never, if you run out of runway before you get there.
The inverse plan — launch broad across the zero-median storefronts before investing anywhere near the size of the US wall — is not intuitive, but it's what the actual distribution of competition supports.
What a single "difficulty" score hides
A tool that gives you one global difficulty number for a keyword is compressing 19 different competitive realities into one. In 6 of them that number is meaningfully high. In 13, it should functionally be close to zero, and isn't.
That compression is not a rounding error, it's a category-wide simplification that this specific dataset makes visible. The full per-storefront table, and the method behind it, is here: how many reviews it actually takes to rank, by country.
We publish this kind of country-level breakdown because it's the thing a single blended score can never show you. If you're deciding where to launch next, check the storefront before you check the keyword — Storelift tracks rank per storefront, not as a global average.
