Did the App Store move today?

Apple never announces an algorithm change. So every morning we compare every tracked keyword and every top-100 chart we hold with the day before, and count the share that moved ten places or more. A calm day means what changed is yours; a shaken day means wait before you touch anything.

App Store: every tracked keyword and every top-100 chart, against the day before.

By storefront

The same reading per country. A shaken storefront on a calm day is a local change, often a category re-ranking.

Shaken days

None yet. When a morning crosses 30% it gets its own dated page here, with who climbed and who fell.

What to do on a shaken day

  1. 1. Do not touch the listing. A change you make today gets credited or blamed for Apple's move.
  2. 2. Open My keywords: the yesterday column shows which of yours moved, and whether the whole store moved with them.
  3. 3. Wait a morning. Half of the shaken days settle back the next day.

How the reading is made

Two samples, every morning at 07:20 UTC
Every keyword tracked on aso.best, position today against yesterday in the same store. And every top-100 chart we snapshot: 22 storefronts, free, paid and grossing, every category for the largest stores.
What counts as moved
Ten places or more, or leaving a list from a position that was not already at its edge. Small moves happen every day and are ignored.
Calm, moderate, shaken
Under 15% moved is a normal day. 30% and over is shaken and gets a dated page. The keyword sample is ignored on days with fewer than 20 comparable positions, so a thin sample cannot swing the reading.
