Frequently asked questions
What is an AEO checker?
An AEO checker audits your website against the signals that AI answer engines like ChatGPT, Claude, and Perplexity use to decide what content to cite. It checks schema markup, llms.txt, crawl access, content structure, and citability.
What is AEO and how is it different from SEO?
AEO (Answer Engine Optimization) is the practice of making your content easy for AI systems to find, understand, and cite. While SEO targets search engine ranking pages, AEO targets AI-generated answers that increasingly appear above those results.
What is llms.txt and do I need one?
llms.txt is a plain-text file at your domain root — similar to robots.txt — that tells large language models what content is available and how to access it. Having one signals to AI crawlers that your site is AI-ready.
Why would an AI engine not cite my site?
Common reasons: blocking AI crawlers in robots.txt, missing or invalid JSON-LD schema, thin or poorly structured content, no clear author or organization signals, and content that does not directly answer specific questions.
How do I fix a low AEO score?
Start with the failing checks in your report. The highest-impact fixes are usually: adding JSON-LD schema (Organization + FAQPage), unblocking AI crawlers in robots.txt, adding an llms.txt file, and structuring content with clear headings and direct answers.
How often should I run an AEO audit?
Run an audit whenever you make significant changes to your site. For actively managed sites, a monthly check is a good baseline — AI engine behaviour and crawling patterns are still evolving quickly.
