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.
Release cadence
Actively maintainedHow 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.

I’m getting ready to launch a new blog and was looking to add an extra layer of protection from bots and scrapers harvesting info from my site. I downloaded the free version of this plugin to try it out and quickly made the decision to upgrade to the Pro version. It’s been worth every penny. I’m very knew to blogging, but the setup for this plugin was very clear and easy to follow. I like that I don’t have to be fluent in code to customize the settings. It’s already blocked at least 8 suspicious ip addresses that were trying to access my site. I love how easy the dashboard is to navigate and see my daily reports. I had a little bit of a learning curve figuring out which settings to turn on, but WhoKnew’s tech support and knowledge base helped me every step of the way. Who Knew Shield is a hidden gem here in the plugin store.
