An SEO audit is a structured check of one page or site against the signals search engines actually use: indexability, metadata, headings, links, speed, and structured data. This guide explains what an audit covers, how to read the results, and what to fix first.
What an SEO audit checks
A quality on-page audit covers HTTP status and redirects, indexability and robots directives, title and description quality, heading structure, canonical tags, structured data, image alt text, internal and broken links, HTTPS, and page weight. You get a score plus a prioritized issue list.
How to read an audit score
Treat the score as triage, not a grade to chase to 100. A page scoring in the 40s with a missing title and no canonical has clear high-impact work; the difference between 82 and 91 is minor polish. Fix every high-priority issue first, re-run to confirm, then work down the list.
The fix order that works
Indexability blockers first — a page search engines cannot reach cannot rank. Then titles, descriptions, and headings, which shape relevance and clicks. Then technical items: canonicals, structured data, image compression, and link health. Verify each fix against live HTML.
From audit to rankings
An audit finds problems; it does not fix rankings by itself. Rankings move when fixes go live and pages get recrawled, typically days to weeks later. Track the audited pages in Google Search Console to confirm the improvements registered.
Site audit versus page audit
Page audits answer: what is wrong with this URL. Site audits answer: what is wrong with this domain — duplicate content patterns, broken internal link networks, crawl-depth imbalance, index bloat. Run page audits on your money pages quarterly, and a full crawl at least twice a year using the bulk checkers that cover status codes, canonicals, and sitemaps together.
Reading issue severity honestly
Audit tools assign severity, but severity is not the same as impact for your specific site. A missing alt text on a decorative icon matters less than a canonical conflict on your top landing page. Use the priority scorer to map audit findings against the pages that actually drive traffic, and fix issues on revenue pages first — even when the tool rates them medium.
Building a fix workflow
The audit-fix-verify loop is where most teams fail. The fix: every issue gets an owner, a deadline, and a verification method. After deployment, re-run the same audit and confirm the specific issue cleared. An audit that is not re-run after fixes is a spreadsheet exercise, not an SEO process.

Frequently asked questions
How is a page audit different from a site crawl?
A page audit analyzes one URL in seconds. A site crawl inspects the entire domain for duplicates, broken links, and structural patterns across all URLs.
What is a good audit score?
Above 80 with zero high-priority issues is healthy. Below 60 almost always means fixable on-page problems are holding the page back.
How often should I re-audit?
After publishing, after template or CMS changes, and quarterly for pages that drive revenue — silent regressions are common.
