Keyword swap (ASO)
A keyword swap means replacing one keyword in your metadata with a better one. In LocalASO the Swap verdict marks the clearest case: you rank in the top 10 for a term, but almost nobody searches it. The ranking exists, but it brings no traffic.
Updated
Why swap
Metadata space is limited. The keyword field holds 100 bytes. A top-10 position for a term with no searchers feels good and delivers nothing, so the bytes work harder somewhere else.
Steps
- Find terms with the Swap verdict, or a dead keyword.
- List replacement candidates from your keyword gap work.
- Choose one with higher search volume and acceptable keyword difficulty.
- Replace it, keeping commas and no spaces.
- Wait for the update, which may take up to 24 hours to appear, and re-check ranks.
Example
A hypothetical habit tracker has habit,routine,streaks,habitual,planner (the habitual entry is 8 bytes plus a comma). It ranks #6 for "habitual" and the volume estimate is near zero. Swapping it for journal (7 bytes plus a comma) keeps the field inside its budget:
Before: habit,routine,streaks,habitual,planner = 38 bytes
After: habit,routine,streaks,journal,planner = 37 bytes
The replacement should still describe the app. Irrelevant terms are not allowed.
What to watch
- LocalASO's volume is an estimate from rating counts and not an Apple count. Confirm a swap on terms where the estimate surprises you.
- Do a metadata update in one locale first if you want a clean comparison.
- Do not remove a term that lives in the name or subtitle. Those fields carry other jobs.
