Google has this hidden feature. Go to Google Search Console, connect your site to it. Go to performance, toggle on average position.
Scroll down to queries. Go to filter position greater than 7. Now you can see searches that your site shows at the bottom of page 1 of Google for or page 2.
Stick to searches between positions 7 and 20. Sort by impressions.
These are searches that you are already ranking for that you can get a lot more clicks for. Either rewrite your page title to target the search better, add something to the page title so it stands out more. Or even take the search term and include a specific H2 section for it on your page.
Then you can show higher for these searches that you are already ranking for so you get more clicks.
