WebSub (FKA. PubSubHubbub)

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 · 51% 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.

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 declining trend compresses what a buyer would pay.

   Just learnt more on the benefits of using WebSub a.k.a PubSubHubbub and love that this plugin did the necessary code to the feed instantly. I can see it worked as a newly published blog was discovered instantly by Googlebot after publish using the marked up feed url that I had submitted to search console sitemaps.

   I needed pubsubhubbub, whatever that is, as part of my WordPress install and this plugin made it brain dead easy to add that capability to my online magazine. So thanks! Now I have to work on figuring out what it does beyond handling behind the scenes notifications of new content through Superfeedr. 😎
