Biggest opportunity: “image compression”, “image optimizer” and “seo” aren't earning a slot. You list them, but you're not in the first 24 results for those searches. WordPress.org counts only your first five tags, so free the slot for a search you can win.

of downloads still active
At least 20 of 811 lifetime downloads are still running, above its category: the median SEO plugin keeps 1.2%, across 1,193 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other SEO plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.

How it's tracked →Directory searches this plugin turns up in, and which way each one is moving. WordPress.org publishes no history of search positions, so this starts the day we first tracked a keyword and never backfills.
Not enough tracked days yet to call a direction. Momentum needs at least three keywords measured a week or more apart.
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 |
|---|---|---|---|
| auto alt your tag | #22 | #23 | 0 |

| image compression your tag | Not in the top 24 | ||
