Free SEO Audit for Any Website

How to do an SEO audit, step by step

You can run a full audit here in one click, but it helps to know what a thorough SEO audit actually involves — the process is the same whether you do it by hand or let a tool do the heavy lifting:

1. Crawl the site the way a search engine does. Start at the homepage, follow internal links to map every reachable page, and note status codes, redirects, and anything blocked in robots.txt.
2. Check the technical foundation. Confirm HTTPS, a valid XML sitemap, and clean canonical tags, and make sure important pages are actually indexable — not accidentally set to noindex or buried behind redirect chains.
3. Review on-page content. Go through title tags, meta descriptions, heading structure, and thin or duplicate content, page by page.
4. Measure performance and Core Web Vitals. Test loading, interactivity, and layout stability against real-user (field) data, not just a lab score.
5. Assess trust and security. Check security headers, mixed content, and the E-E-A-T signals that both search engines and AI models weigh.
6. Check AI-era readiness. See what AI crawlers actually render, whether your answers are extractable, and whether your structured data and semantic HTML make the site machine-readable.
7. Prioritise by impact. Rank every issue by how much it affects rankings and fix the critical ones first.

This tool does all seven automatically and hands you the prioritised list — but the steps are worth knowing so you can act on the results with confidence.

How to read your report

Your audit opens on a dashboard with an overall grade (A–F) and a score for each category. Every issue is labeled critical, warning, or notice, with a plain-English explanation and a recommended fix. Start with the critical issues — they have the biggest impact on rankings — then work down. You can export the full report as a designed PDF or a multi-tab Excel workbook to share with your team.

Why AI-era SEO (AEO, GEO, AIO) matters

Search is no longer just blue links. Answer engines pull concise answers, and generative AI tools cite sources directly. Our audit checks whether your pages are structured for featured snippets (AEO), trustworthy enough to be cited by AI (GEO), and machine-readable for large language models (AIO) — factors most traditional SEO tools ignore. You can also spot-check individual signals with our AI Bot Access Checker, AI Model Recall Checker and llms.txt Generator, or read the SEO audit guide.

How often should you run an SEO audit?

For most sites, a full audit every quarter is enough to catch drift — broken links, new redirect chains, pages that slipped out of the index, or content that has gone stale. Run one sooner if you’ve launched a redesign, migrated to a new domain or CMS, changed your URL structure, or seen traffic drop in Google Search Console. Because the audit is free and takes only minutes, you can re-run it after every significant change and watch the grade move. If you’d rather not remember to check, our free AI-Readiness Monitor tracks your pages on a schedule and emails you when something changes.
