Biggest opportunity: Swap “optimization”, “performance” and “cleanup” for “delete”, “duplicate posts” and “duplicate”. “optimization” isn't earning its slot: you're not in the first 24 results for its own search. “delete” sits at #4 untagged, close enough for a declared tag to move it up. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “duplicate posts” sits at #4 untagged, close enough for a declared tag to move it up. “cleanup” isn't earning its slot: it only gets you to #24. “duplicate” sits at #7 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →1.1%
of downloads still active
At least 10K of 919.6K lifetime downloads are still running, in line with its category: the median Performance plugin keeps 1.4%, across 1,103 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 5 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

What to do about it
- Swap “optimization”, “performance” and “cleanup” for “delete”, “duplicate posts” and “duplicate”. “optimization” isn't earning its slot: you're not in the first 24 results for its own search. “delete” sits at #4 untagged, close enough for a declared tag to move it up. “performance” isn't earning its slot: you're not in the first 24 results for its own search. “duplicate posts” sits at #4 untagged, close enough for a declared tag to move it up. “cleanup” isn't earning its slot: it only gets you to #24. “duplicate” sits at #7 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- Slipping on “cleanup”. Down 7 places since 2026-09-19, now #24. Check what shipped around then, and what moved above you.

I can’t remember if I have already left a review, but even a duplicate review (hope it does get deleted if exists) is worth it. Does what it promises, very quickly, for free at least for my demands. Good plugin, good work, thank you
