Biggest opportunity: “cache” and “object cache” 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 9K of 1M lifetime downloads are still running, below its category: the median Performance plugin keeps 1.4%, across 1,103 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance 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.
| Keyword | wp.org | On merit | wp.org move, 90 days |
|---|---|---|---|
| redis your tag | #3 | #5 | down 1 |
| apc | #5 | #4 | down 1 |
| redis cache | #6 | #7 | 0 |
| persistent object cache | #14 | #11 | up 1 |
| cache your tag | Not in the top 24 | ||
| object cache your tag | Not in the top 24 | ||
17 searches this plugin appeared in over the last 90 days, 4 listed. 13 left out as unrelated or noise (years, numbers, stray words). 2 of its tags aren't in the top 24 for their own search.

Great free Redis plugin which even does not need to be kept installed. Just install and copy object-cache.php to wp-content. Then add a wp-config setting (after installing redis on your server) and you are good to go. Check with WP health on dashboard. Thanks to the developers!

Great plugin. I’m evaluating it now as a backend Redis cache. However, installation was not straightforward or clear. I wish it was automatic. However, the manual install requires copying a file manually. If you run multiple WordPress sites on a self-hosted install, you must also make sure to edit the object-cache.php file and add a cache salt key or you will get errors. Once these are resolved, it seems to be functioning well. 4 stars for the excellent plugin.-1 for the difficult installation. I wish it were more straightforward.

Well maintained, free and open source plugin which only job is to implement a redis-based object cache, which does it well.

It is working great!, How does this plugin differs with “Redis Object Cache” since you don’t offer premium subscription for the plugin? drop-in based, no need to activate the plugin, just follow the GIT Instruction. Currently on my staging environment for testing.

If you have a specific environment then put aside a day, if you’re not comfortable with ssh then don’t do it.
