Biggest opportunity: “css”, “javascript” and “page” 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 400 of 27.1K 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.
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 14+ years — the top precursor to removal once a vulnerability is found.
- Compatibility drift. Tested only up to WordPress 3.4.2, 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 |
|---|---|---|---|
| css your tag | Not in the top 24 | ||
| javascript your tag | Not in the top 24 | ||
| page your tag | Not in the top 24 | ||
| post your tag | Not in the top 24 | ||

All reviews on wp.org ↗- ★★★★★ Josh Davenport12.4y ago
This plugin is working even though it hasn’t been updated for a long time. Just bear in mind that when you save your changes from your post, the save button doesn’t actually give any feedback. After you have clicked save, click out of the lightbox and update the post. The changes will be saved and appear on the frontend. With that little UX issue resolved this plugin is worth 5 stars and it’s wonderfully simple for getting CSS/JS into specific posts/pages.

Hi. I want to insert javascript not on a single page but on all the pages. What changes do I need to make in the plugin code so that I can do that ? Thanks.

I insert the Javascript code and the page seems to work fine for awhile, then the code disappears and I have to re-insert it and re-save. This has happened several times and is quite annoying. Do not use this plugin.

Worked fine for me and a great option to add css to a single post or page which is exactly what I needed it to do! I’d prefer to have the javascript and css functionality separate but that’s simply because I don’t need the javascript bit. Thanks for developing. The other thing was I couldn’t immediately see the icon as was expecting a custom css box below the page edit area and instead it’s a small icon just below the page title – that’s the only thing I would change and that way you can see the css immediately.
