Biggest opportunity: Swap “bookings” and “calendar” for “jquery calendar” and “airbnb”. “bookings” isn't earning its slot: it only gets you to #24. “jquery calendar” sits at #4 untagged, close enough for a declared tag to move it up. “calendar” isn't earning its slot: it only gets you to #12. “airbnb” sits at #5 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 10K of 499.7K lifetime downloads are still running, above its category: the median Booking & Events plugin keeps 0.8%, across 944 plugins.

What to do about it
- Swap “bookings” and “calendar” for “jquery calendar” and “airbnb”. “bookings” isn't earning its slot: it only gets you to #24. “jquery calendar” sits at #4 untagged, close enough for a declared tag to move it up. “calendar” isn't earning its slot: it only gets you to #12. “airbnb” sits at #5 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- Slipping on “bookings”. Down 12 places since 2026-09-19, now #24. Check what shipped around then, and what moved above you.
- One page off on “calendar”. #12 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

It’s a good product but its pro licencing doesn’t allow for staged websites, which means we have to go through deregistering and regegistering everytime we promote an update from staged to the live website. We have since been contacted by support who kindly extended the website limit, and we can now test and promote to our live website. With that we are happy to extend our star award for both product and its support. This topic was modified 1 month, 3 weeks ago by eddiebt. This topic was modified 1 month, 3 weeks ago by eddiebt.

I’ve been using WP Simple Booking Calendar for over 5 years, and it’s been a game-changer for managing reservations. When I hit a snag with migration and accented characters, Roland from Veribo resolved it quickly and professionally. The plugin is stable, the support is excellent, and I couldn’t ask for more. Highly recommended!

Have been using the plugin for many years and recently had an issue with a ics feed not importing. Their support was prompt and noticed Cloudflare was blocking the connection. I was able to resolve the issue with some custom code after their help identifying the problem

If you have one item to rent, the free version is sufficient as you can keep things up to date manually. We need it for several calendars and decided for the pro version, also to synch with other calendars. Synching works very well. With the great help of support/developer and their additional code we were able to use ACF fields to dynamically retrieve the respective booking calendars inside the Elementor single post templates. One template to rule all the properties. So that “simple” does not mean limited. True WordPress spirit!

The name says it all: a simple booking calendar. Very clear, it’s not bloated and easy to set up. Worth paying for pro version.

An excellent tool for reservations. And excellent support. Roland implemented an update with the new calendar functionality at our request in less than 12 hours. Thanks to him.
