Free SEO Audit for Your Website

What is an AI SEO audit?

Classic technical SEO audits rest on one assumption: a crawler fetches your HTML, an index stores it, and a ranking algorithm orders the results. AI answer engines break that chain in two places. They crawl with their own user agents, which your robots.txt may quietly be blocking. And they don't return a ranked list of ten links — they synthesise a single answer and credit a handful of sources. A site can clear every Core Web Vitals threshold and still be invisible to all of them.

What an AI SEO audit checks

• AI crawler access. Whether GPTBot, ClaudeBot, PerplexityBot and Google-Extended are actually allowed through, in robots.txt and at the server level. Blocking them is usually accidental — inherited from a template or a CDN rule nobody revisited. Check yours with the free AI Crawler Access Checker.
• llms.txt coverage. Whether you publish an llms.txt file telling AI systems which pages matter and how to describe them — the emerging equivalent of robots.txt for answer engines. Generate one here.
• Rendering without JavaScript. Most AI crawlers don't execute JS. If your copy only appears after hydration, they see an empty shell where your content should be. See what they see.
• Citation-ready structured data. Whether your schema markup hands an answer engine the facts it needs to quote you accurately. FAQPage and HowTo map almost directly onto how AI answers are formatted, so they carry outsized weight. Score your markup.
• An AI Readiness score. All of the above rolled into one number you can track over time and put in front of a client.

Every free SearchVitals audit runs these checks alongside the traditional technical, on-page and performance ones, so a single report covers search engines and answer engines instead of stitching two tools together. If you want the strategy behind them first, our complete guide to generative engine optimization (GEO) explains how AI systems discover and cite content, and what to change on your site.
