Black Bar

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 · 35% 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.

   This plugin allowed me to pinpoint performance issues, not only within my code, but also in used plugins that were not optimised enough.

   Was wondering why my wordpress installation was unbearably slow. This plugin helped me discover the massive amount of SQL queries generated by 2 conflicting plugin settings. Problem solved!

   This plugin can make life easier when a quick debug is needed. I use it specially to inspect what my $_GET, $_POST, $_SESSION, $_COOKIES variables look like.
