Biggest opportunity: Swap “custom css” and “footer codes” for “codes” and “highlighter”. “custom css” isn't earning its slot: you're not in the first 24 results for its own search. “codes” sits at #5 untagged, close enough for a declared tag to move it up. “footer codes” isn't earning its slot: it only gets you to #12. “highlighter” sits at #11 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →4.8%
of downloads still active
At least 1K of 20.9K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,778 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.
This plugin shipped 1 release 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
- Swap “custom css” and “footer codes” for “codes” and “highlighter”. “custom css” isn't earning its slot: you're not in the first 24 results for its own search. “codes” sits at #5 untagged, close enough for a declared tag to move it up. “footer codes” isn't earning its slot: it only gets you to #12. “highlighter” sits at #11 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “footer codes”. #12 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.
