Biggest opportunity: Swap “minify css”, “minify javascript” and “unused css” for “assets”, “booster” and “clean”. “minify css” isn't earning its slot: it only gets you to #14. “assets” sits at #4 untagged, close enough for a declared tag to move it up. “minify javascript” isn't earning its slot: it only gets you to #13. “booster” sits at #9 untagged, close enough for a declared tag to move it up. “unused css” isn't earning its slot: it only gets you to #12. “clean” sits at #9 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 100K of 5.1M lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,104 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 3 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 “minify css”, “minify javascript” and “unused css” for “assets”, “booster” and “clean”. “minify css” isn't earning its slot: it only gets you to #14. “assets” sits at #4 untagged, close enough for a declared tag to move it up. “minify javascript” isn't earning its slot: it only gets you to #13. “booster” sits at #9 untagged, close enough for a declared tag to move it up. “unused css” isn't earning its slot: it only gets you to #12. “clean” sits at #9 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- Slipping on “unused css”. Down 6 places since 2026-09-18, now #12. Check what shipped around then, and what moved above you.
- One page off on “minify css”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.
- One page off on “minify javascript”. #13 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

It does where I was looking for.
Read on wp.org ↗ - ★★★★★ Mary Bouldin6mo ago
I’ve been working on my own site instead of client work lately, and I am highly unreasonable. I add too many complex codes and plugins, and have made a ridiculous game out of my website. The Divi 4 WordPress pages and items in the builder and the library all stopped saving after edits, and the only way I could go back to my preferred level of insanity was to shut down unnecessary stuff on pages across the site. <3

i have been using it for roughly 3 months now and it has helped with my performance tweak for my sites. plus the learning curve is simple if well you put in the time. Overall a good complementary plugin for Performance optimization

While it does have lots of options and can be intimidating it is just that powerful. If you know what you are doing this plugin can really speed your website up considerably.
