A free, AI-powered SEO checker that analyzes your site across 26 factors in about 60 seconds — then tells you exactly what to fix first.
What is an SEO audit?
An SEO audit is a health check of your website’s ability to rank in search engines. It looks at the technical foundation, the content on each page, how fast and secure the site is, and — increasingly — how well your pages are understood by AI and answer engines. A good audit doesn’t just list problems; it ranks them by impact so you know what to fix first.

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 Visibility Checker and llms.txt Generator, or read the SEO audit guide.
