Biggest opportunity: Add “embedding”, “meetings” and “meeting” to your wp.org tags. You rank #6, #16 and #20 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 3 listed these are the slots worth spending.

How it's measured →6.1%
of downloads still active
At least 2K of 32.8K lifetime downloads are still running, above its category: the median Booking & Events plugin keeps 0.8%, across 941 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 4 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 |

What to do about it
- Add “embedding”, “meetings” and “meeting” to your wp.org tags. You rank #6, #16 and #20 for them without listing them, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 3 listed these are the slots worth spending.
