And what we deliberately do not sell." url: https://picobit.ai/en/technical-implementation language: en updated: 2026-09-25 --- *GEO optimization* # Technical implementation So that ChatGPT, Google, Perplexity, Gemini, Copilot and Claude can reach, read and cite your website. We check, implement and document every change. [Request a check](https://picobit.ai/en/contact) A reply within one working day, from the person who measures. ## Machines read differently from people. And from Google. Many websites block AI crawlers without knowing it. In most answers ChatGPT reads only the title and a snippet around the main heading. Anything rendered by JavaScript does not exist for it. - **40%** of landing pages effectively lock out well-behaved AI crawlers. (Source: [Zyte, 11,100 landing pages, September 2026](https://www.zyte.com/blog/robots-txt-ai-crawlers/)) - **9 in 10** ChatGPT answers in default mode open no page at all. (Source: [Resoneo, 682 ChatGPT answers in default mode, July to August 2026](https://think.resoneo.com/chatgpt-retrieval/)) - **~80%** of AI crawler traffic serves training. (Source: [Cloudflare, AI crawler traffic across its network, July 2025](https://blog.cloudflare.com/ai-crawler-traffic-by-purpose-and-industry/)) ## Six checks Each with a measurable before and after. ### Crawler access Which bots reach you and whether a block is intended. Search and training decided separately. - One rule per bot, with a reason - Verified in the server log ### Readability without JavaScript Is the content in the HTML, or does it only appear in the browser? - Raw HTML against rendered page - Page weight within limits ### The first characters The heading and what surrounds it are often all that gets read. - Heading answers the question - Paragraphs extractable on their own ### Internal linking Crawlers find pages through links, not the sitemap. - Find orphaned pages - Link from pages already read ### Company data Name, location, services: identical everywhere. Contradictions produce false statements. - Reconcile all your own sources - Structured data for entity clarity ### Measurability Make AI visits and fetches visible in your own tools. - AI assistant channel in your analytics - Crawler analysis from the log ## What we implement, what we don't ### We implement - Crawler access per bot - Content in the delivered HTML - Clear first characters on every page - Internal linking - Consistent company data - Sourced figures and citations in your own text ### We don't sell - llms.txt as a lever: Google calls it unnecessary, Ahrefs found it almost never fetched - Schema markup as a citation lever: no effect in an Ahrefs controlled study - Keyword stuffing "for the AI": worse than nothing in the KDD study - Mass AI-generated pages - Bought mentions and directory listings ## The crawlers that matter - **OAI-SearchBot**: The search index behind ChatGPT. Blocked: invisible in ChatGPT answers with web search. - **GPTBot**: Training data for OpenAI. Blocked: no effect on search visibility. - **ChatGPT-User**: Real-time fetch on a user question. OpenAI documents that robots.txt does not always apply. - **PerplexityBot, Perplexity-User**: Index and real-time fetch for Perplexity. Blocked: no citation there. - **ClaudeBot, Claude-SearchBot**: Training and search for Claude. Decided separately. - **Google-Extended**: Training of Google's models only. No effect on AI Overviews. - **Googlebot**: The search index, and with it AI Overviews and AI Mode. Blocked: invisible on Google. Terms such as crawler, entity and structured data are explained in [AI visibility, explained](https://picobit.ai/en/ai-visibility#terms). ## Two things first ### Google and the others are not the same Google's guide says its AI features need no special files and no special markup ([Google Search Central, May 2026](https://developers.google.com/search/docs/fundamentals/ai-optimization-guide)). True for Google. ChatGPT has its own index; Perplexity fetches sources live. We say for every measure which engine it is meant for. Where GEO goes beyond SEO is set out under [GEO compared with SEO](https://picobit.ai/en/ai-visibility#geo-seo). ### Part of the effect lies outside your website The strongest measured correlations concern mentions elsewhere: trade media, review platforms, forums. We do not offer that work. We show you which third-party sources the engines cite and where you are missing. More under [AI visibility](https://picobit.ai/en/ai-visibility). ### How we work In your system, with your people. We need access to the CMS and the server logs. Every change is dated so it can be matched to a reading. How we measure is described in our [measurement methodology](https://picobit.ai/en/methodology). ## Can machines read your website? Give us your address. We check which crawlers reach you and what an engine finds first.
