Smart Custom 404 Error Page

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 · 91% 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.

Reviewers call it simple to set up and say it just works, with one older complaint that it altered a theme's stylesheet.

   Followed instructions, got the page built and configured it to go to the page when a 404 error occurred. However it wrecks the Divi theme by changing the CSS. I have switched to something else which does not affect the theme. This plugin was easy to set up, so no problem with that. Shame it is affecting the style sheet settings.

   Simple to install and configure, and it does just what it says it would.. What more can I ask for.
