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.

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

At the current install trend, crossing 80+ in roughly 81 days.

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.

   Everything is fine, but it causes a WordPress error The PHP session was created by calling the function session_start(). This prevents the REST API and loopback requests from working. The session must be closed by the function session_write_close()before making any HTTP requests. This topic was modified 5 months, 2 weeks ago by dimail.

   Full disclosure: I am the developer. I originally built this plugin for my own projects because I needed a simple and effective way to stop spam. One year after publishing it, I’m leaving this review to confirm it’s still running flawlessly on all my sites. It has completely eliminated spam on my forms. It’s a “set it and forget it” solution that just works.
