# AEOCheck - Full Content > Free AI search readiness audit tools. Start with a free AEO scan, then choose > a $19 Fix Pack or $99 human-reviewed audit when you need implementation help. ## LLMs.txt Checker Check whether your site has a valid LLMs.txt file, accessible AI-readable links, LLMs-full.txt, sitemap, and AI crawler access. The checker validates: - LLMs.txt file existence and HTTP status - Link structure and formatting in your LLMs.txt - LLMs-full.txt availability - Sitemap.xml accessibility - Robots.txt with AI crawler rules for OpenAI, Anthropic, Perplexity, Google, Common Crawl, Apple, and Meta crawlers ## LLMs.txt Generator Generate a clean LLMs.txt file for your website from your sitemap or manual inputs. The generator creates properly formatted Markdown with your site structure, key pages, and descriptions that AI systems can parse efficiently. ## AEO Checker Run a technical AEO audit covering seven dimensions: 1. Crawlability - HTTP status, title, meta description, canonical URL, meta robots 2. AI Search Files - LLMs.txt, LLMs-full.txt, sitemap, robots.txt with per-crawler access analysis 3. Structured Data - JSON-LD detection, schema type enumeration, parse error reporting 4. Answer-Ready Content - Heading hierarchy, FAQ sections, question-format headings, list usage, short answer paragraphs 5. Entity Clarity - Brand name inference, og:site_name, Organization schema, brand mention count 6. Trust Signals - Author attribution, published/modified dates, About/Contact/Privacy links, external references ## Query Fan-Out Tool Simulate how AI search engines expand a query into sub-queries, intents, and content gaps. Enter a query to see potential fan-out patterns that help you plan comprehensive, answer-ready content. ## High-intent AI Search Readiness Pages The site now exposes focused entry points for searchers who already have a specific SEO, AEO, or GEO problem: - AI Crawler Checker: https://aeocheck.xyz/tools/ai-crawler-checker - Robots.txt AI Crawler Checker: https://aeocheck.xyz/tools/robots-txt-ai-crawler-checker - GEO Audit Tool: https://aeocheck.xyz/tools/geo-audit - AI Overview Readiness Checker: https://aeocheck.xyz/tools/ai-overview-readiness-checker - ChatGPT Citation Readiness Checker: https://aeocheck.xyz/tools/chatgpt-citation-readiness-checker - Sample AEO Report: https://aeocheck.xyz/sample-aeo-report - AI Search Readiness Checklist: https://aeocheck.xyz/guides/ai-search-readiness-checklist - Is the AI Search Readiness Report Worth It?: https://aeocheck.xyz/compare/ai-search-readiness-report-worth-it These pages route visitors toward the free AEO Checker, the optional $19 AI Search Readiness Fix Pack, and the $99 Manual AI Search Readiness Audit.
