Biggest opportunity: “cache”, “memcached” and “object” 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 →0.2%
of downloads still active
At least 10 of 4.6K 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 |
|---|---|---|---|
| memcache your tag | #7 | #20 | up 9 |
| spider | #7 | #19 | 0 |
| cache your tag | Not in the top 24 | ||
| memcached your tag | Not in the top 24 | ||
| object your tag | Not in the top 24 | ||
| output your tag | Not in the top 24 | ||
7 searches this plugin appeared in over the last 90 days, 2 listed. 5 left out as unrelated or noise (years, numbers, stray words). 4 of its tags aren't in the top 24 for their own search.
What to do about it
- “cache”, “memcached” and “object” 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.

Health trend
Composite health score, snapshotted daily
Update activity
Downloads in the last 30 days for every 1,000 active sites.
Not enough installs to measure. This needs at least 100 active sites; below that, a handful of downloads reads as tens of thousands.
Release cadence

Estimated active installs
The public count shows “10+”. Our estimate pins where the real number sits.
Crossed into this band 2 months ago and a band this size takes about a year or more to cross, so the real count is still just under 20.

When Memcache module is not loaded with PHP I get a fatal error instead of an explaination. I use PHP 7.1 and my host doesn’t offer Memcache, only Memcached. Also files must be copied manually to wp-content.

This plugin has no settings. Zero. It Just Works. Running it on my eCommerce website and not a single problem. Faster admin, just as fast front-end as running W3 Total Cache, and I don’t need to tweak settings. Thanks @jjj!
