High removal-risk signals

63/100

Maintenance and integrity signals that tend to precede a WordPress.org removal. Not an official status, a heads-up to act.

  • Long abandoned. No update in 15+ years — the top precursor to removal once a vulnerability is found.
  • Compatibility drift. Tested only up to WordPress 3.0.5, well behind 6.8.

Update activity

How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Estimated value

What this plugin might earn a year, and what it might sell for. Modeled from public signals; we don't see anyone's books.

Est. annual revenue

Est. acquisition value

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.

    Adds fields for header and footer inserts below the page content of individual pages. Perfect!

    This plugin works very well. I just think it is too bad it do’est allow to choose a default head/header injection and that it is only on a per-post system.

    Was a little put off with the “This plugin has not been updates in 2 years” thing but have no fear! I am using 3.8 and it works perfectly. Such an amazingly useful plugin! LOVE IT!!!!

    Still works like a charm. Don’t be fooled by “This plugin hasn’t been updated in over 2 years….”

    Tested to work in WordPress 3.5.1 with Headway 3.4.8. If you use CloudFlare with your site and discover that injected JavaScript does not seem to work, add data-cfasync=”false” to the opening script tag: http://stackoverflow.com/a/10611827
