High removal-risk signals
63/100Maintenance 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 10+ years — the top precursor to removal once a vulnerability is found.
- Reviews souring. Recent reviews read meaningfully worse than older ones, an early sign of decline.
- No tested-up-to version. The listing declares no "Tested up to" version.

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 loved having this plugin, but I had to delete it because there’s no support. The free books never update, and the link is usually broken.

I love the idea behind this plug-in. Nice way to generate some extra income while providing your visitors with a useful service. Easy to set up and works great.

Very easy to install and use – it does what it says. New free kindle books are updated automatically in your sidebar everyday with your amazon affiliate code attached to them so you can generate extra income.
