Theme Check

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. 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. The recent download trend is too spiky to read.

   I heard good things about this plugin until I used it. It says my theme name and text domain/slug do not match. They do so why is it flagging a non-existent error?

   One of the best plugins for theme developers. Really a very good job! Have you never thought to create a similar plugin to check plugins? Plugins developers would also need a so helpful tool.

   This is a great plugin for everyone that really likes to develop a WordPress theme and make successfully tests for the basic WordPress standards. The errors separated in ‘Required’, ‘Warning’, ‘Recommended’ and ‘info’. Also provide the basic information of this error and makes you understand where the problem is.
