SEO Page Auditor

Give it a page on your own site; it measures what is wrong on the page itself — title, headings, description, alt text, thin copy — and tells you what to fix first.

Checks one page's HTML. It cannot see your rankings, traffic, backlinks or Search Console, and it does not crawl the rest of the site. Every defect it reports is measured, so you can re-run it after fixing and watch the row disappear.
