Do local and English searches show the same top 10 apps?

The Jaccard index divides the number of apps in both top-10 lists by the number of apps in either list. Identical lists score 1.0 and lists with no app in common score 0. A score of 0.26 means that, on average, roughly a quarter of the apps seen across the two lists appear in both. Pairs with 0.5 or more were 93 of 753 (12.4%), counted from the CSV.

The 41 non-English storefronts fall into four bands of mean overlap (each storefront has 15 to 19 pairs).

The lowest overlap was in Greece, Malaysia and Bulgaria, and the highest in Germany, Spain and Italy. Zero-overlap pairs were concentrated in a few places: 8 of 19 pairs in both Greece and Bulgaria, and 5 each in Sweden, Norway and Slovakia, against 1 each in France, Italy, Spain and Japan and none in Germany, Austria or Switzerland.

The local phrases are candidate translations that no native speaker checked. If a candidate phrase is awkward, apps may not use it, and the search can drift to loosely related results; that would lower overlap without saying anything about real users. The reverse is also possible: a very natural phrase can match a different set of apps than a translated-literally English one because people use each language differently. The data cannot separate these explanations.

Overlap also depends on how global the leading apps are, which this data does not measure. The study of non-Latin app names shows how often app names there use local script.

If the two lists overlap by about a quarter, a keyword you rank for in English may not describe the same competition in the local language. That is a reason to check the local phrase's top 10 yourself rather than inherit your English results. It is not evidence that translating always improves rank. The related local-language versus English comparison shows what happened to volume. For the process, see the guide on translating or transcreating keywords. Volume and difficulty are LocalASO estimates from rating counts, not Apple search counts.

Overlap uses the app IDs of the top 10 results for each phrase, one snapshot per phrase on 2026-11-01. Results vary by device, account and time. See the methodology page.

LocalASO checks keywords in 52 storefronts, each in its local language, and shows volume and difficulty for every keyword you track there. It is a one-time $29 Mac app and needs a license key to run. See pricing.
