Biggest opportunity: Swap “avif” for “possibly”. “avif” isn't earning its slot: you're not in the first 24 results for its own search. “possibly” sits at #12 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 20 of 2K lifetime downloads are still running, below 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 26 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

Great plugin for a WooCommerce store with lots of product images. Running a sports clothing webshop (msportsofficial.com) means a lot of product photos, like jerseys, caps, hoodies across multiple categories and clubs. Image file sizes were adding up fast and slowing things down.Shrinkwell handled the bulk optimization smoothly. The 5-image test run before going all-in was a smart touch. Exactly what you want before touching a full product media library. Backups were kept automatically, so there was no risk involved. WebP versions were generated and the delivery test confirmed they were actually being served on the frontend.No external API, no account, no monthly fee. Everything runs on the server itself. For a WooCommerce store where product images directly affect conversions, faster load times matter, and Shrinkwell delivered that without any hassle. Solid plugin, actively updated, and does exactly what it promises.
