Biggest opportunity: Swap “cache” for “super cache”. “cache” isn't earning its slot: you're not in the first 24 results for its own search. “super cache” sits at #16 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 →7.0%
of downloads still active
At least 1K of 14.3K lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,099 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.

We recently switched to WP Compress and the cache would stay stale even after content updates. This plugin helped change that!!!

Especially after the update to allow a custom version string, either through a GUI setting or programmatic hook, this plugin fixes a persistent problem when doing site updates. Too often we have browsers holding onto cached CSS/etc after doing an update. We want them cached, but wanted a way to invalidate those when changes are made. This now allows us to use the version as a “point in time” refresh point. Caching will happen until we tell it a new version is installed. It works perfect for us. Thanks so much to Mwale for sharing this freely!
