What is LLM Optimisation (LLMO)?
LLMO (Large Language Model Optimisation) is a new discipline that optimises a website and content so that AI search engines (ChatGPT, Perplexity, Google AI Overviews, Bing Copilot) display your brand and content as a trusted source.
Traditional SEO optimises the Google search results page. LLMO optimises AI-generated answers — different algorithms, different signals and different strategies. In 2026, already ~30% of searches happen through AI platforms.
What does LLMO implementation cover?
llms.txt file creation
llms.txt is the new robots.txt for the AI era. The file tells AI crawlers how to understand your site and which content to cite. A standardised format accepted by all major AI engines.
Structured data optimisation
Schema.org markup, JSON-LD structure and FAQ format help AI systems understand and cite your content as a reliable answer to user questions.
Passage-level citability
Structuring content so that individual paragraphs can be cited in AI answers. H2/H3 structure, "answer formats" and concise statements increase the probability of being cited.
Brand mention monitoring in AI
Monitoring whether ChatGPT, Perplexity and Google AI mention your brand when answering relevant questions. Gap identification and content creation for missing topics.
AI crawler accessibility audit
Technical audit: whether AI crawlers (GPTBot, PerplexityBot, Google-Extended) can access your content. robots.txt configuration, page speed and JavaScript rendering.
E-E-A-T signal strengthening
Author credentials, company information structure, expert claims and citation building — the signals AI systems use to assess source trustworthiness.
