App-store rank & review monitoring (ASO)
App Store and Google Play rankings, search suggestions and even review ordering differ per country and per storefront. ASO teams tracking keywords across 20 markets need per-country IPs — a single-geo crawler reports charts nobody in the target market actually sees.

How to set up — step by step
1. One country = one storefront = one geo pin
Google Play localises by IP and account country; the App Store by storefront. To read the charts a user in Japan sees, request through a Japanese residential IP with the right store parameters — mixing geos mid-crawl silently corrupts a whole tracking run.
2. Track suggestions, not just ranks
Search-suggestion order is the cheapest ASO intel there is: it shifts days before chart positions move. A daily suggestion snapshot per keyword per market through the same geo-pinned setup costs a few MB and often pays for the whole pipeline.
3. Reviews need pagination discipline
Review feeds are paginated and rate-limited harder than charts. Pull deltas only (newest since last crawl), space the requests, and rotate per storefront rather than per page — burning one IP across 40 review pages of one app is the classic ban pattern here.
⚡ Store quirks worth knowing (checked 11.07.2026)
Google Play serves different results for the same query depending on device profile embedded in the request headers — keep a consistent mobile UA per run or ranks jitter. The App Store's charts endpoint regionalises by storefront ID first and IP second, so a mismatched pair (US IP + JP storefront) returns a blend that matches neither market. Both stores throttle datacenter ASNs on review feeds well before charts — residential matters most on the review leg.
