Biggest opportunity: Swap “pregnancy calculator” for “pregnancy”. “pregnancy calculator” isn't earning its slot: it only gets you to #11. “pregnancy” sits at #12 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 100 of 5.7K 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.

What to do about it
- Swap “pregnancy calculator” for “pregnancy”. “pregnancy calculator” isn't earning its slot: it only gets you to #11. “pregnancy” sits at #12 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “pregnancy calculator”. #11 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.
