WP Simple Booking Calendar

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

Share of active installs on each version of this plugin · 94% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Modeled within the band wp.org reports; tightens as we track daily.

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.

   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.
