Keyword snapshot

A keyword snapshot is a stored capture of one keyword's search results on a single day, for a specific store, country, and language: the ordered list of the top apps the store returned for that term, in that market, at that moment. Each unique combination of keyword, store, country, and language has its own snapshot, saved every day you track it.

That granularity matters because the same keyword does not rank the same everywhere. Each country is a separate storefront with its own catalogue of available apps, its own popularity signals, and its own demand, so the leaders for a term in the United States can be unknown in Japan. Language changes the results again: people search in their own words, and a localised listing only competes for the terms it is actually translated for, so "budget" in English and "Haushaltsbuch" in German surface different apps. The Apple App Store and Google Play rank with different algorithms on top of all that. A single global number would blur it together, so every snapshot stays pinned to one store, one country, and one language.

Snapshots are what make ranking history possible. By saving the results every day, you can look back and see exactly where your app stood, who ranked above and below it, and when a competitor first appeared or overtook you, even though the live store only ever shows today's results.

On AppTracker, a daily snapshot captures the top 20 apps for each keyword in each store, country, and language you track, so both your position and the competitive field around you are preserved for every day.
