Indexly's AI Readiness Audit is a Generative Engine Optimization (GEO) tool that evaluates your website's accessibility to AI crawlers — including GPTBot (OpenAI), ClaudeBot (Anthropic), PerplexityBot, and ChatGPT-User. Get comprehensive crawlability reports, generate llms.txt files, audit your robots.txt for AI bot access, and receive a scored readiness report with actionable technical fixes to maximize your content's discoverability across AI search platforms.
Real-time optimization insights
Indexly's AI Readiness Audit evaluates your website across six dimensions of AI crawler optimization — from robots.txt configuration for GPTBot and ClaudeBot to llms.txt generation and structured data validation — providing a scored report with prioritized action items.
LLM crawlability analysis is a comprehensive evaluation of how accessible your website is to AI-specific crawlers. Indexly checks your robots.txt rules for GPTBot, ClaudeBot, ChatGPT-User, and PerplexityBot; measures page load speed; tests AI bot accessibility; and identifies technical barriers preventing AI content discovery and indexing.
An llms.txt file is a structured text file that helps large language models understand your website's purpose, authority, and key content areas. Indexly automatically generates optimized llms.txt files by analyzing your content structure, identifying authoritative pages, and creating descriptions that improve how AI systems represent your brand in their responses.
AI content optimization involves structuring your pages so language models can accurately extract and cite your information. Indexly provides recommendations for semantic keyword usage, Schema.org markup implementation, heading hierarchy, and content accessibility — all factors that determine whether AI platforms select and accurately represent your content.
AI bot detection identifies which AI crawlers are accessing your website and how they interact with your content. Indexly monitors GPTBot, ClaudeBot, ChatGPT-User, PerplexityBot, and Google-Extended crawling patterns, providing detailed access logs and identifying pages that are being blocked or underperforming in AI discovery.
Technical SEO for AI crawlers focuses on the infrastructure requirements that AI bots prioritize when selecting content. This includes server response times, mobile rendering, structured data completeness (JSON-LD, Schema.org), SSL configuration, canonical URL setup, and content accessibility — factors that differ from traditional Googlebot requirements.
The AI Readiness Score is a composite metric that rates each page's optimization level for AI crawler access on a 0–100 scale. Indexly scores pages across crawlability, structured data, content quality, technical performance, and llms.txt coverage — with prioritized action items showing which fixes deliver the highest impact for AI visibility.

Learn how Indexly's AI Readiness Audit optimizes your website for AI crawler discovery, llms.txt generation, and content representation across ChatGPT, Claude, Gemini, and Perplexity.
An AI Readiness Audit is a systematic evaluation of how well your website can be discovered, crawled, and understood by AI systems like ChatGPT (OpenAI), Claude (Anthropic), Gemini (Google), and Perplexity. Unlike traditional SEO audits that focus on Google ranking factors, an AI Readiness Audit evaluates AI-specific factors: robots.txt rules for GPTBot and ClaudeBot, llms.txt file presence, structured data for entity extraction, and content formatting for LLM comprehension. As AI platforms become primary sources of information for millions of users, ensuring your content is optimized for AI discovery is essential for maintaining brand visibility and accurate representation.
Indexly's AI Readiness Audit analyzes compatibility with all major AI crawlers: GPTBot and ChatGPT-User (OpenAI), ClaudeBot (Anthropic), PerplexityBot (Perplexity AI), Google-Extended (Google Gemini), and CCBot (Common Crawl, used by many AI training pipelines). For each crawler, the audit checks your robots.txt configuration, verifies crawling permissions, tests page accessibility, and identifies content that may be inadvertently blocked from AI discovery.
An llms.txt file is a structured text document placed at the root of your website (e.g., yoursite.com/llms.txt) that provides large language models with context about your site's purpose, authority, and key content areas. Benefits include: more accurate brand representation in AI-generated responses, better contextual understanding by language models when citing your content, increased likelihood of being referenced as a credible source, and clearer communication of your expertise areas to AI systems. Think of it as a business card optimized for AI — it tells ChatGPT, Claude, and Perplexity what your site is about and which pages matter most.
The key technical factors that AI crawlers evaluate include: robots.txt configuration with AI-specific user agent rules, page load speed (AI crawlers have timeout thresholds), mobile responsiveness and rendering, structured data markup (JSON-LD using Schema.org vocabulary), SSL/TLS certificate validity, HTTP response codes and redirect chains, canonical URL configuration, sitemap.xml completeness, and content accessibility (no JavaScript-only rendering that blocks crawlers). AI crawlers like GPTBot and ClaudeBot have different requirements than traditional Googlebot, making specialized auditing essential.
For active websites, Indexly recommends running AI Readiness Audits monthly, since AI crawler behavior and platform requirements evolve rapidly. Additional audits should be triggered by major site redesigns, CMS migrations, content restructuring, robots.txt changes, or new page templates. Indexly's automated monitoring continuously tracks AI crawler access patterns and alerts you to changes in crawlability, so you can address issues before they impact your AI visibility.
Generative Engine Optimization (GEO) is the practice of optimizing website content to be discovered, understood, and cited by AI-powered search engines and language models — including ChatGPT, Claude, Gemini, and Perplexity. While traditional SEO focuses on ranking in Google's search results, GEO focuses on being accurately represented and cited in AI-generated responses. Key GEO techniques include creating llms.txt files, adding comprehensive structured data, writing definition-style content that AI can extract cleanly, and ensuring AI crawlers have full access to your pages. Indexly's AI Readiness Audit is a foundational tool for implementing a GEO strategy.
Traditional SEO audits focus on Google and Bing ranking factors: backlinks, keyword density, meta tags, Core Web Vitals, and internal linking. An AI Readiness Audit evaluates a different set of factors specific to AI platforms: robots.txt rules for GPTBot, ClaudeBot, and PerplexityBot; llms.txt file presence and quality; content structure for LLM comprehension (definition paragraphs, comparison tables, FAQ sections); Schema.org structured data for entity extraction; and overall content accessibility for AI training and retrieval-augmented generation (RAG) pipelines. Both audits are complementary — modern visibility requires optimizing for both traditional search and AI discovery.
