What is an SEO audit?

SEO audit, explained

Good audits start with Google's own data, not a crawler's score. Search Console's Page indexing report shows which pages Google left out and why. The Performance report shows which pages and queries already get impressions. Manual actions and Security issues rule out the rare serious problems. Then a site crawl fills in what Google doesn't show: status codes, redirect chains, canonicals, titles, headings, internal links and orphan pages.

A practical order: first, can Google reach and index the pages that matter (status codes, robots rules, noindex, canonicals, rendering, sitemap)? Second, is each important page clearly about one thing and good at it (titles, headings, content depth, duplicates, cannibalization)? Third, is the site structured so pages are found and connected (hubs, depth, internal links)? Fourth, is it fast and usable on mobile (Core Web Vitals, HTTPS)? Links and authority come after the site itself is sound.

The output should be a short, prioritized list, not a 200-row spreadsheet. Automated tools flag hundreds of issues, most harmless: missing alt text on decorative icons, meta descriptions a few characters long, H1 warnings. Rank by impact on pages that matter, fix the handful that affect indexing or many pages at once, and ignore the rest.

Re-audit after big changes like migrations, redesigns or large content batches, and do a light check monthly in Search Console. On a new domain, the first audit is really a setup checklist.

Why it matters for founders

Founders often get sold audits full of noise. Knowing what a useful one looks like helps you fix the few things that matter and skip the rest.

Example

Your audit finds a sitewide canonical bug, 300 thin tag pages and slow LCP on the homepage. You fix the canonical first, noindex the tag pages second, and leave 90 minor warnings alone.

Common mistakes

• Starting with a crawler score instead of Search Console data.
• Treating every warning as equally important.
• Auditing once and never checking again.
• Fixing cosmetic issues before indexing problems.
