Database Collation Fix

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 · 100% 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.

Reviewers say it does one job and does it well, fixing illegal mix of collations errors on old or messy databases in a couple of clicks, and the newest review from 2026 is just as happy as the older ones.

   Fixed up so many odd and random issues. Hard to believe that DB collation could be/was related to some of the oddball issues I was having… but I was certainly surprised & thrilled to see things working properly again!
