The New GEO & AI Checks
Chatbots are increasingly replacing traditional search engines!
Search behavior is changing fast .. today people no longer use only search engines, they also turn to AI systems to find information and do research. Tools like ChatGPT, Claude, Google Gemini and Perplexity are replacing search engines. To get mentioned there, you have to follow new rules. Optimizing for them is called GEO (Generative Engine Optimization) or AIO (AI Overview Optimization). SEORCH is a free SEO tool that puts your website through its paces for these AI search engines and autonomous agents!
All checks in detail
Here is an overview of all the checks SEORCH runs fully automatically in the background for your website:
| Check / Criterion | Area | Meaning & how it works |
|---|---|---|
| 1. robots.txt Openness | AI / LLM | Checks whether your robots.txt allows, blocks or accidentally locks out the search crawlers of LLMs such as ChatGPT (GPTBot), Claude (ClaudeBot) or Applebot. |
| 2. XML Sitemap Detection | Technical | Makes sure AI crawlers can quickly find your sitemap.xml so that your latest pages get indexed in no time. |
| 3. llms.txt Integration | AI / LLM | Looks for a standardized /llms.txt file in the root directory, which gives AI systems a concise, machine-readable summary of what you offer. |
| 4. ai.txt Configuration | AI / LLM | Checks for a standardized /.well-known/ai.txt that tells AI crawlers in detail how they may use your data for training. |
| 5. HTTP Link Header (RFC 8288) | Technical | Validates whether your server responses include structured Link headers, so that AI agents can discover your interfaces automatically. |
| 6. Markdown for AI Agents | AI / LLM | Analyzes whether your website offers an optimized text version (content negotiation) to AI systems that prefer to process structured Markdown content. |
| 7. Content Signals (robots.txt) | AI / LLM | Looks for modern, AI-specific directives such as ai-train=no in your robots.txt to protect your copyright against AI models. |
| 8. API Catalog (RFC 9727) | Technical | Looks for a standardized API catalog interface at /.well-known/api-catalog that autonomous agents can use to interact with your services. |
| 9. MCP Server Card (SEP-1649) | Technical | Detects whether you offer Model Context Protocol (MCP) Server Cards, which give AI models direct contextual access to your databases. |
| 10. Agent Skills Index | Technical | Checks for a standardized skills index (/.well-known/agent-skills/index.json) that provides AI agents with predefined tools for solving problems. |
| 11. WebMCP Browser API | Technical | Detects interfaces for the direct exchange of data and context between the user's browser and AI models. |
| 12. Universal Commerce Protocol (UCP) | Technical | Detects decentralized cart and shop interfaces (e.g. Shopify-compatible JSON configurations) that let AI agents read products directly. |
| 13. Agentic Commerce Protocol (ACP) | Technical | Checks for autonomous checkout and ordering interfaces at /.well-known/acp.json for direct transactions by AI agents. |
| 14. Authorship & E-E-A-T | GEO | Analyzes author boxes and structured person data (Schema.org), because AIs strongly prioritize trustworthy content from real experts (E-E-A-T). |
| 15. Cloudflare CDN & WAF Protection | Technical | Checks whether your Cloudflare CDN or web application firewall is accidentally blocking useful AI services such as ChatGPT Search. |
| 16. Structured Data (Schema.org) | GEO | Looks for valid JSON-LD (WebSite, Product, Article, FAQ) so that AIs can structure and cite your content, prices and FAQs without errors. |
| 17. Heading Structure (H1-H6) | GEO | Analyzes the semantic and hierarchical order of your headings, so that language models can follow the logical thread of your page perfectly. |
| 18. Content Quality | GEO | Checks the text length, information density and whether there is a search-engine-optimized meta description. |
| 19. Rendering Type (SSR vs. CSR) | Technical | Analyzes whether your page uses server-side rendering (SSR). AIs prefer SSR, as pure client-side rendering (CSR) is often not rendered correctly. |
| 20. Server & Hosting Integrity | Technical | Checks PTR records, server headers and the TCP/IP response status for requests from AI user agents to uncover hidden server-side blocks. |
| 21. Common Crawl Index Coverage | AI / LLM | Checks in real time whether your website is included in the Common Crawl index, to make sure your content is taken into account in upcoming AI model training. |
| 22. AI Text Probability | AI / LLM | Uses Google Gemini 3.5 to analyze your main text for typical language patterns and stock phrases, to assess how strongly the text sounds AI-generated. |
