Biggest opportunity: Swap “performance” and “optimize” for “emoji” and “fast”. “performance” isn't earning its slot: it only gets you to #22. “emoji” sits at #4 untagged, close enough for a declared tag to move it up. “optimize” isn't earning its slot: it only gets you to #20. “fast” sits at #4 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 →1.5%
of downloads still active
At least 1M of 68.5M lifetime downloads are still running, in line with 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 12 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.

The plugin does exactly what it’s supposed to. Settings are easy to configure; there are no unnecessary bells and whistles. And if you have any questions, the support team is very responsive and provides helpful solutions.

I had a really specific problem with my license because of my self-hosted website. They replied immediately to my request and found an amazing solution. For me it was very important, because it’s my familyblog and speed matters. This plugin accelerated my Site to an absolute next Level. I would give more stars, but there are only 5 possible. For me it would be 15: 5 for the speed 5 for the simple setup and gui 5 for the support Best paid plugin I ever used.
