What is an AI SEO audit?
An AI SEO audit checks whether AI assistants can reach, read and trust your pages. It covers robots.txt rules for AI crawlers, llms.txt, schema markup, page speed and crawl blockers, the technical layer that decides whether ChatGPT, Perplexity or Google AI can use your content at all.
Is an LLM SEO audit the same thing?
Yes. "LLM SEO audit", "AI SEO audit" and "ChatGPT SEO audit" all describe the same check: can large language models crawl and understand your site. This page runs it. To see what those models actually say about your brand, run an AI visibility audit as well.
Can ChatGPT do an SEO audit?
ChatGPT can review a page you paste in, but it can't crawl your whole site, test your robots.txt against each AI bot or measure Core Web Vitals. A dedicated audit does that across every page, then hands the findings back as fixes you can work through.
What is an AI crawlability audit?
It checks which AI crawlers can get into your site. GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot, Google-Extended and the rest each follow their own robots.txt rules, and blocking the wrong one can keep you out of ChatGPT Search or Gemini answers. This audit checks 23 of them, plus Googlebot and Bingbot.
How is an AI SEO audit different from a technical SEO audit?
A technical SEO audit is built for Google rankings. An AI SEO audit keeps those checks and adds the ones AI search depends on: AI crawler access, llms.txt, and structured data that assistants use to understand who you are and what you sell.
Which tools audit robots.txt, llms.txt and schema together?
The page audit checks all three for any URL, from Agent Mode, the MCP server or the API, at 1 credit per page. For a quick look, the free robots.txt AI checker and llms.txt generator cover the first two, and the free AEO checker gives a one-page readiness score.
What metrics do you measure?
Google Lighthouse, run through PageSpeed Insights, gives the Performance, Accessibility, SEO and Best Practices scores plus lab timings: LCP, CLS, Total Blocking Time, First Contentful Paint and server response time. Where Chrome has enough real-user data, the audit adds the field Core Web Vitals: LCP, INP and CLS. Each metric includes detailed breakdowns and actionable recommendations. Technical SEO checks use no credits; a Lighthouse audit costs 1 credit per page.
How does this differ from Google Lighthouse?
We use Lighthouse under the hood but add AI-specific analysis, historical tracking, competitor comparisons, and prioritized recommendations tailored for AI search visibility. Our audits focus on factors that influence whether AI systems cite and recommend your content, not just traditional search rankings.
Can I audit competitor websites?
Yes! Audit any public website to benchmark against competitors. See how your technical SEO compares to industry leaders and identify opportunities to outperform them. Great for competitive analysis and understanding what makes top-ranking sites successful.
How often should I run audits?
We recommend running Lighthouse audits after major site changes and at least monthly to catch new issues. Technical SEO checks use no credits and come with Starter or the trial, up to a daily limit; Lighthouse audits draw on your monthly credits. Regular monitoring helps you maintain optimal performance and catch issues before they impact rankings.
How does SEO affect AI visibility?
AI systems like ChatGPT and Perplexity prioritize well-structured, fast-loading, accessible pages with proper schema markup. Good technical SEO improves your chances of being cited and recommended by AI platforms. Core Web Vitals, mobile-friendliness, and structured data are especially important for AI visibility.
What's included in issue reports?
Each issue includes a clear description, severity level (critical/high/medium/low), estimated impact on performance, affected pages, and specific step-by-step instructions to fix it. Issues are automatically prioritized by importance so you can focus on high-impact fixes first.
How long does an SEO audit take?
Technical SEO checks complete in 30 to 60 seconds. Lighthouse audits take 1-2 minutes per page as they perform comprehensive performance analysis. Results are displayed in real-time with progress indicators so you know exactly what's being analyzed.
Can I export audit results?
Yes! Export audit results as PDF reports or CSV data for sharing with your team or clients. White-label branding for those exports is included on the Agency and Agency Plus plans.
What if my site blocks crawlers or sits behind a WAF?
The scanner detects pages blocked by firewalls or bot protection and automatically retries them through a proxy fallback, so you get complete results instead of a wall of false "unreachable" errors. Pages that other audit tools give up on still get scored.
What happens with the issues the audit finds?
They land on your Tasks board as suggested tasks, prioritized with impact and effort estimates. Accept the ones you want, fix them, and the next scan verifies.
