Biggest opportunity: Swap “meta”, “seo” and “meta description” for “modification”, “google webmaster tools” and “webmaster tools”. “meta” isn't earning its slot: you're not in the first 24 results for its own search. “modification” sits at #8 untagged, close enough for a declared tag to move it up. “seo” isn't earning its slot: it only gets you to #19. “google webmaster tools” sits at #9 untagged, close enough for a declared tag to move it up. “meta description” isn't earning its slot: it only gets you to #15. “webmaster tools” sits at #10 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 10K of 202K 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.
