Free AEO Checker — Answer Engine Optimization Audit
Answer Engine Optimization (AEO) is the practice of optimizing your website to be discovered, understood, and cited by AI-powered search engines like ChatGPT, Perplexity, Google AI Overviews, and Claude. As more users turn to AI for answers instead of traditional search, AEO is becoming essential for online visibility.
What does the AEO Checker analyze?
Our tool evaluates your website across 5 key categories: Technical Foundations (HTTPS, robots.txt, llms.txt, page speed), Meta & Structured Data (title, description, OpenGraph, JSON-LD, FAQPage schema), Content Quality (headings, word count, FAQ sections, citations), AI-Specific Signals (llms.txt quality, answer blocks, speakable markup, author signals), and Cloudflare & Access (challenge pages, bot blocking).
What is llms.txt?
llms.txt is a proposed standard file (similar to robots.txt) that helps AI crawlers understand what your website does. Placing a descriptive llms.txt file at your site root gives AI engines context about your content, services, and expertise — making them more likely to recommend your site in their responses.
How is the AEO score calculated?
Your site is scored out of 100 points across 5 categories. A grade of A (85-100) means excellent AI readiness, B (70-84) is good with minor gaps, C (55-69) needs significant work, D (40-54) is poor, and F (below 40) means your site is nearly invisible to AI engines. Each check includes actionable recommendations.
