Biggest opportunity: Swap “appointment booking”, “appointments” and “booking” for “time slots”, “time slot booking” and “barbershop”. “appointment booking” isn't earning its slot: you're not in the first 24 results for its own search. “time slots” sits at #4 untagged, close enough for a declared tag to move it up. “appointments” isn't earning its slot: you're not in the first 24 results for its own search. “time slot booking” sits at #5 untagged, close enough for a declared tag to move it up. “booking” isn't earning its slot: you're not in the first 24 results for its own search. “barbershop” sits at #10 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →0.5%
of downloads still active
At least 100 of 19.4K lifetime downloads are still running, below its category: the median Booking & Events plugin keeps 0.8%, across 944 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Booking & Events plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 15 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

This plug-in simplified booking appointments and I couldn’t imagine a better one out there. It was easy to set up and for a great price too. Setting up payments was easy and there was documentation that explained anything I wanted to know more about!
Read on wp.org ↗ - ★★★★★ vthierry1.3y ago
Among half a dozen of booking plugins, times-lot has been evaluated as the best choice for our small online+face-to-face company activity, and we enjoy using it: + Doing well the job with all essential features, as advertised, easy to configure. + An excellent clear and sound documentation for non expert installation. + A rather cheap and clear price (no complex price “scarfolding”). + The plugin internal php code is really well written up to our best expertise. +++ The development team is really kind and super reactive and effectively helping.Merci beaucoup 🙂 This topic was modified 11 months, 3 weeks ago by vthierry.
