Cross-checked against Google Play
Google Play stayed within its normal range in Poland that day, at 3% of its keywords against 8% for that day of the week. Apple and Google rank apps through independent systems, so a shift on one that leaves the other steady is specific to the App Store.

Frequently asked questions
What happened to App Store rankings on September 18, 2026?
In Poland, 17% of keywords moved by 10 places or more in a single day, about 2.8 times what this market normally does. The typical keyword moved 1 places, against 0.0 on an ordinary day in the weeks before, and 4% of the positions measured fell out of the top 100 entirely.
Did Apple or Google announce this?
No. Neither store announces search algorithm updates. They are only visible by measuring thousands of keyword ranks every day and looking for days that break the pattern, which is what this page does.
Was it just this country?
No other market moved at this scale that day, which points to a change specific to Poland rather than a global rollout.
What should I do after an update like this?
Nothing on day one. If the drop is store-wide, rewriting your metadata changes your indexing for no reason and destroys your ability to read what happened. Wait two or three days, confirm the new level, then decide.
Was your app caught in this?
Applyra tracks your keyword ranks every day on both stores, so the next time the store moves you will know exactly which of your keywords went with it.
