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

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. 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.

   I am a property photographer and I also do floor plans and some video. Tried out the free version which is good but doesn’t allow certain things including accepting card payments. Purchased Business Medium and it adds much more functionality and customization options. The get the best out of it helps to know a bit about HTML and CSS as you need to dig in to the Advanced Mode and configure things “manually” to get it to look and work just right. My knowledge of HTML and CSS is quite basic and I struggled a but but the support is unbelievably good and fast. They helped me configure things and provided me with some code to copy and paste. I still had to figure some of it out on my own but the help form support is top notch and they respond quickly. I tried out some other booking forms but I settled on this one as it has extensive options and flexibility and a good back end where it is easy to keep track on bookings, availability, etc. Would highly recommend this plugin – at least try the free version to start with as that will help you make up your mind if it is right for you.

   I recently took on the challenge of developing my own website for my vacation rental. A key feature of the website was the booking calendar for my customers. After reviewing various plugins and weighing the pros and cons of each, I decided that WP Booking Calendar would be the best choice. Since I had never worked with a booking calendar before, I was entering uncharted territory. WP Booking Calendar offers extensive documentation and videos on configuring the calendar, but there were specific nuances related to my business that I struggled to navigate. At times, I felt lost regarding how to implement my desired modifications. I reached out to WP Booking Calendar Support multiple times, and they provided prompt guidance on making the necessary changes, including assistance with my shortcodes. Thank you, WP Booking Calendar Support! You helped me get my website up and running promptly.
