Biggest opportunity: “classes” isn't earning a slot. You list it, but you're not in the first 24 results for that search. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active
At least 2K of 28.2K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,770 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
High removal-risk signals
63/100Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.
- Long abandoned. No update in 8+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 4.8.34, well behind 6.8.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
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 |
|---|---|---|---|
| classes your tag | Not in the top 24 | ||
1 search this plugin appeared in over the last 90 days, 0 listed. 1 left out as unrelated or noise (years, numbers, stray words). 1 of its tags isn't in the top 24 for their own search.
What to do about it
- “classes” isn't earning a slot. You list it, but you're not in the first 24 results for that search. WordPress.org counts only your first five tags, so free the slot for a search you can win.

Release cadence
