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

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 · 73% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

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.

Reviewers call it simple and quick to set up with no configuration needed, and the only gripe is a syntax highlighter that's sometimes off without breaking anything.

   Works perfectly. The syntax highlighter is sometimes incorrect, but it doesn’t affect functionality. Thanks to the developers.
