Definition
LLM SEO (Large Language Model SEO) is the practice of optimising a website, its content, and its digital presence so that large language models — including ChatGPT, Perplexity, Claude, Gemini, and others — discover, understand, and cite the business in their responses. Unlike traditional SEO which targets Google's ranking algorithm, LLM SEO targets the training data, retrieval systems, and citation logic of AI models. A business that is well-optimised for LLMs appears in AI-generated answers, comparisons, and recommendations — representing a new category of organic visibility.
The problem
LLMs cannot cite businesses they cannot clearly identify as entities — vague "About" pages fail this test
AI systems prefer to cite sources with structured, extractable, factually clear content — most websites have none
Without schema markup, LLMs cannot understand what services you offer or who you serve
AI systems cite well-linked, well-mentioned businesses — obscure digital footprints get ignored
Generic marketing copy is not citeable — LLMs need specific, authoritative, answer-style paragraphs
Most businesses are not tracked in AI model training data or retrieval indexes at all
The solution
We audit your current LLM visibility by querying ChatGPT, Perplexity, Claude, and Gemini for your core target queries. We identify exactly why you are not appearing and build a structured programme to fix it: entity optimisation, content restructuring, schema implementation, digital footprint expansion, and citation acquisition.
