Search Console Triage
Export your Search Console performance data, drop it here, and get the three things worth acting on: what is close to page one, what is ranking well but losing the click, and where the biggest recoverable clicks are.
Your file never leaves your browser. Parsing and analysis run entirely on this page. Nothing is uploaded, stored, or sent anywhere.
Drop
Queries.csv or the export ZIP
Search Console › Performance › Export › CSV.
Pages.csv works too.
Striking distance
Ranking 11 to 20, with enough impressions to be worth a push. These are already relevant to Google. They just are not on page one yet.
Losing the click
Page one already, but the click-through rate sits well under what this site normally earns at that position. That is usually a title and meta description problem, not a ranking problem.
