Delete Duplicate Posts

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 · 36% 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 declining trend compresses what a buyer would pay.

Reviewers say it does exactly one job and does it fast, with several calling it simple and well suited to large sites.

   I can’t remember if I have already left a review, but even a duplicate review (hope it does get deleted if exists) is worth it. Does what it promises, very quickly, for free at least for my demands. Good plugin, good work, thank you
