Biggest opportunity: Add “japanese calendar” to your wp.org tags. You rank #10 for it without listing it, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 4 listed it's a slot worth spending.

How it's measured →3.5%
of downloads still active
At least 200 of 5.8K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,765 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized 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 1 release 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 |
|---|---|---|---|
| gengo your tag | #1 | #2 | 0 |
| wareki | #1 | #1 | 0 |
| japanese calendar | #10 | #18 | — |
| i18n your tag | #12 | #15 | 0 |
| date your tag | Not in the top 24 | ||
| japanese your tag | Not in the top 24 | ||
5 searches this plugin appeared in over the last 90 days, 4 listed. 1 left out as unrelated or noise (years, numbers, stray words). 2 of its tags aren't in the top 24 for their own search.
What to do about it
- Add “japanese calendar” to your wp.org tags. You rank #10 for it without listing it, close enough for a declared tag to move you up. WordPress.org counts only your first five tags, so with 4 listed it's a slot worth spending.
- One page off on “i18n”. #12 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.
