Biggest opportunity: Swap “image optimization” and “media library” for “image converter” and “imagick”. “image optimization” isn't earning its slot: you're not in the first 24 results for its own search. “image converter” sits at #13 untagged, close enough for a declared tag to move it up. “media library” isn't earning its slot: you're not in the first 24 results for its own search. “imagick” sits at #23 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 100 of 68K lifetime downloads are still running, below 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 6 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.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

What to do about it
- Swap “image optimization” and “media library” for “image converter” and “imagick”. “image optimization” isn't earning its slot: you're not in the first 24 results for its own search. “image converter” sits at #13 untagged, close enough for a declared tag to move it up. “media library” isn't earning its slot: you're not in the first 24 results for its own search. “imagick” sits at #23 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “webp converter”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

I was looking for a way to inside optimize the size of images on my website (.png to .webp) and found this plugin. Quick installation, easy to use. Just a link next to the media file. The bulk conversion didn’t work, so I wrote to the developer. He helped and fixed the problem quickly. Richard handled my problem with understanding and support, so I only get 5*. Thank you!
