Biggest opportunity: Swap “compress” and “image” for “resizer” and “360”. “compress” isn't earning its slot: you're not in the first 24 results for its own search. “resizer” sits at #4 untagged, close enough for a declared tag to move it up. “image” isn't earning its slot: you're not in the first 24 results for its own search. “360” sits at #18 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

0.7%

of downloads still active

At least 1K of 139.6K 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 8 releases 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.

Reviewer account pattern

from wp.org reviewer profiles

18 of the last 28 four- and five-star reviews came from accounts created within a month of posting the review.

Registering a wp.org account just to leave a review is common and often entirely legitimate. The share here is unusually high for the sample, so it's worth keeping in mind while reading the reviews.
