Biggest opportunity: “credit card”, “e commerce” and “payment” 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.

How it's measured →1.9%
of downloads still active
At least 100 of 5.3K lifetime downloads are still running, above its category: the median Payments plugin keeps 1.0%, across 1,043 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Payments plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

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 |
|---|---|---|---|
| credit card your tag | Not in the top 24 | ||
| e commerce your tag | Not in the top 24 | ||
| payment your tag | Not in the top 24 | ||
| payment request your tag | Not in the top 24 | ||
| shopping your tag | Not in the top 24 | ||
3 searches this plugin appeared in over the last 90 days, 0 listed. 3 left out as unrelated or noise (years, numbers, stray words). 5 of its tags aren't in the top 24 for their own search.

Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.
Release cadence
No release in a yearHow often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.
