LLM SEO is the practice of making your website easy for answer engines to retrieve, understand, trust, and cite. A classic SEO audit tells you whether a page can rank. An LLM SEO audit goes one step further and asks whether a model can actually reuse your page inside an answer for ChatGPT, Perplexity, Gemini, or Google AI Overviews. That is a different standard. The strongest pages are not just indexed. They are extractable, specific, well-structured, and clearly tied to a credible brand.
That is why an AI visibility checker matters for modern content and growth teams. If the opening answer is vague, the page lacks schema, or your strongest evidence is buried too deep, the model can skip your site even when Google rankings look healthy. Good ChatGPT SEO depends on clean headings, answer-first formatting, trust signals, freshness, and strong internal links between educational and commercial pages. A free SEO audit AI workflow helps you spot that gap quickly. Instead of guessing why your website is missing from AI answers, you get a practical score, a six-factor breakdown, and a direct path to the fixes most likely to improve AI visibility and conversion.
