A keyword is not one market. The same phrase can be crowded in the US, reachable in Canada, ignored in Brazil, and irrelevant in Germany.
Country comparison keeps ASO from becoming US-only by accident. If your app can serve users in more than one country, the best first opportunity may not be the biggest storefront. It may be the storefront where demand, competition, language, and conversion fit line up.
Compare demand and difficulty together
A country is not attractive just because difficulty is low. It also needs enough demand, a relevant audience, and a product page that can convert that market.
Use four labels instead of one score: demand, difficulty, relevance, and readiness. Demand asks whether the keyword is worth caring about. Difficulty asks whether the current winners are beatable. Relevance asks whether the searcher wants your product. Readiness asks whether your listing is prepared for that country.
A country with medium demand and low difficulty can be better than a country with high demand and brutal competition. A country with low difficulty but no localized page may need prep before it deserves a metadata update.
Look at the actual top apps
Country comparison should include the apps ranking now, their ratings, metadata, screenshots, localization quality, and whether the result feels stale.
Do not only compare your own rank. Compare the result page. Are the top apps local brands? Are they global category leaders? Are their subtitles translated well? Do screenshots show local currency, local examples, local units, or local language? Are ratings concentrated in that country or carried by global volume?
Check whether the keyword means the same thing
The same English word can have different intent by market, and translated phrases can split into multiple local terms. Before localizing metadata, search the phrase and inspect what Apple returns. If the top results solve a different problem, the phrase is not the right target.
This is especially important for health, finance, education, travel, and utility apps where local language and regulation can shape intent.
Layer in your own analytics
If App Store Connect already shows impressions, product page views, downloads, or revenue from a country, use that as a reality check. Existing weak conversion can mean the listing needs local proof. Existing downloads with no localization can mean the market already understands the product.
If there is no country signal at all, country keyword scans can still be useful, but treat them as exploration. Do not overinvest before you see signs of demand.
Use country scans to sequence localization
Start where the keyword is reachable and the product promise makes sense. That may mean localizing metadata first, screenshots first, pricing first, or not localizing yet.
A practical sequence is: compare five to ten countries for one important keyword, shortlist the two or three with the best demand/difficulty fit, inspect competitors manually, then choose one localized experiment. Keep the first experiment small enough that you can measure it.
What to write down
For each candidate country, write one sentence: “This country is worth testing because...” The answer should include search demand, current competition, product fit, and the first localization action. If the sentence is vague, the country is not ready.
