Present in the index, invisible in results.
WHAT THIS MEANS
Being indexed means eligible to rank. It does not mean ranking.
Most pages on most sites rank for nothing, which is normal.
THE LIKELY CAUSES
The query is too competitive for your site's authority The content does not match search intent The content is thinner or less useful than what ranks The site is new and has little authority Nobody links to the page The page is buried and rarely crawled
DIAGNOSING
Search the query yourself and look at what ranks. Is your page genuinely better? Is it even the same kind of page?
Check Search Console for that page: does it get impressions at all? Impressions with no clicks means you rank somewhere, just not visibly.
WHAT TO DO
Target less competitive queries where you can realistically be the best answer Improve the page substantially rather than adjusting it Link to it from other pages on your site Earn a link or two
WHAT NOT TO DO
Keep adjusting keywords on a page that is fundamentally less useful than the competition.
