A free on-page audit tool from Backlinko that scores any URL on a 100-point scale across titles, meta descriptions, H1s, canonical tags, internal linking, and content health. The fix list comes prioritized, which saves time over running a generic crawl tool that returns everything at once.
How to use it
Open the On-Page SEO Checker and paste the URL you want to audit.
Submit and wait for the audit to complete. It typically takes under thirty seconds.
Review the overall score out of 100 with category breakdowns.
Walk through the prioritized fix list, starting with critical and high-impact issues.
Make the fixes in your CMS, then rerun the audit to confirm the score moves.
Repeat for your top ten priority pages until each crosses 80+.
Best-fit use cases
