Keep the evidence with your decisions

The result tables preserve the observations behind each finding. Filter rows to focus your review, add notes to the main table and export a CSV. Use the text report to keep the method and limitations alongside the data.

A local diagnostic answers a bounded question about the input you provide. It does not prove how a search engine crawled, indexed or ranked your site. Follow up with a live check or the relevant first-party report when the decision depends on that evidence.
