Image Optimizer, Resizer and CDN – Sirv

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 68% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Modeled within the band wp.org reports; tightens as we track daily.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from.

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.
