Biggest opportunity: “avif”, “cache” and “redis” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active
At least 10 of 1.4K 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.

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.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| apcu | #14 | #12 | down 1 |
| sqlite | #18 | #15 | down 4 |
| avif your tag | Not in the top 24 | ||
| cache your tag | Not in the top 24 | ||
| redis your tag | Not in the top 24 | ||
| varnish your tag | Not in the top 24 | ||
| webp your tag | Not in the top 24 | ||

Directory rank
Ranked about #30,100 to #45,000, alongside the other plugins at 10+ installs. Plugins with the same install count swap places between wp.org requests, so this is where most of them sit. Checked monthly, last on 21 Oct 2026.
Update activity
Downloads in the last 30 days for every 1,000 active sites.
Not enough installs to measure. This needs at least 100 active sites; below that, a handful of downloads reads as tens of thousands.
Estimated active installs
The public count shows “10+”. Our estimate pins where the real number sits.
Crossed into this band 15 days ago and a band this size takes about a year or more to cross, so the real count is still just under 20.
