Biggest opportunity: Swap “appointment” for “calendly”. “appointment” isn't earning its slot: you're not in the first 24 results for its own search. “calendly” sits at #13 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 →13%
of downloads still active
At least 2K of 15.4K lifetime downloads are still running, above its category: the median Booking & Events plugin keeps 0.8%, across 940 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 3 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.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.
| Keyword | wp.org | On merit | wp.org move, 90 days |

This hasn’t been tested for WordPress version 6.9 and it didn’t work when I installed it. I just got “Error Code: 404. Call Link seems to be wrong.” and couldn’t resolve the issue. I suggest trying another solution. This topic was modified 6 months, 2 weeks ago by kptguven.

If you haven’t heard of Cal.com, they’re a killer open-source alternative to Calendly (cal.com is a much better product design and UX wise, imo). They just launched a WP plugin for easy integration on your WordPress site. It definitely rocks and you should be using this plugin + product right away.
