Biggest opportunity: Swap “add style” and “custom css” for “d3” and “codemirror”. “add style” isn't earning its slot: you're not in the first 24 results for its own search. “d3” sits at #8 untagged, close enough for a declared tag to move it up. “custom css” isn't earning its slot: you're not in the first 24 results for its own search. “codemirror” sits at #22 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 1.7K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,772 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.

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 |
|---|---|---|---|
| codemirror | #22 | #23 | down 3 |
| add style your tag | Not in the top 24 | ||
| custom css your tag | Not in the top 24 | ||
| custom javascript your tag | Not in the top 24 | ||
| custom js your tag | Not in the top 24 | ||
| customize theme your tag | Not in the top 24 | ||
3 searches this plugin appeared in over the last 90 days, 1 listed. 2 left out as unrelated or noise (years, numbers, stray words). 5 of its tags aren't in the top 24 for their own search.
What to do about it
- Swap “add style” and “custom css” for “d3” and “codemirror”. “add style” isn't earning its slot: you're not in the first 24 results for its own search. “d3” sits at #8 untagged, close enough for a declared tag to move it up. “custom css” isn't earning its slot: you're not in the first 24 results for its own search. “codemirror” sits at #22 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
