LLM SEO (large language model SEO, also called ChatGPT SEO) is the discipline of getting your business cited by name inside AI chatbot answers. When someone asks ChatGPT "who is the best AI SEO agency in London?" we want your name in the response. From £999/mo, Transformation Junction builds the technical access, corroboration stack and citation-ready content that makes that happen.
Named in answers
Cited as a source
Recommended by name
LLM SEO - also called ChatGPT SEO - is the practice of optimising your business to be cited inside the answers that large language models (LLMs) generate. ChatGPT, Perplexity, Claude, Gemini and Copilot all pull from web content, brand signals and indexed data to decide which businesses to name when users ask for recommendations. LLM SEO builds the specific signals each platform requires.
ChatGPT (in search mode) pulls from Bing's index. A business needs: (1) pages indexed by Bing via Bingbot, (2) OAI-SearchBot crawler access, (3) factual, well-structured content with clear entity signals, (4) corroborated brand facts across multiple independent sources. Without all four, you are invisible to ChatGPT search regardless of your Google ranking.
Perplexity indexes content via PerplexityBot, with strong weighting on Bing indexation, topical authority and the factual density of pages. It pulls sources by name - "according to [brand]" - which means businesses with clear, factual, well-attributed content get named while vague content gets paraphrased without credit.
Claude (in search mode) and Gemini pull from their own crawlers and, in some modes, from Google's index. High topical authority, clear entity signals in structured data and consistent brand information across the web are the common factors across all LLMs.
A user asking ChatGPT "who should I hire for AI SEO in London?" is not browsing - they are ready to buy. They have skipped the research phase. The business ChatGPT names in that moment earns the enquiry at a much higher close rate than a cold Google click. LLM SEO targets this highest-intent moment directly.
Five technical and content disciplines that together build citation across ChatGPT, Perplexity, Claude and Gemini.
We verify OAI-SearchBot, PerplexityBot, Claude-User and Bingbot can reach your site, and whitelist their IP ranges at the CDN/firewall level where needed.
We submit your sitemap to Bing Webmaster Tools, set up BingSiteAuth, use IndexNow for fast crawl triggering and verify key pages appear in Bing's index - the shared index ChatGPT and Perplexity pull from.
We align your brand name, address, description, credentials and founder details across GBP, LinkedIn, Bing, Clutch, sector directories and on-site schema - the multi-source validation LLMs need to trust a business.
We build a hub-and-spoke content cluster covering every question buyers ask AI tools about your service - so LLMs recognise you as the authoritative source on your topic, not a one-page website.
We write content with specific, citable facts about your service, credentials, results and process - the precise type LLMs extract and attribute rather than paraphrase without credit.

LLM SEO (large language model SEO, often called ChatGPT SEO) is the practice of optimising a business to appear in the answers generated by AI tools like ChatGPT, Perplexity, Claude and Gemini. It focuses on Bing indexation, AI crawler access, entity corroboration and topical authority - the signals LLMs use to decide who to cite.
Yes. LLMs do not weight citations by business size - they weight by content quality, entity consistency and topical authority. A focused small business with strong LLM SEO foundations can appear in ChatGPT answers ahead of large competitors with unstructured content. The slot is available now, before most small businesses know it exists.
Partially. Google rankings are not directly used by ChatGPT - it pulls from Bing's index. However, the content quality, topical authority and schema that drive Google rankings also signal trust to LLMs, so good SEO and LLM SEO overlap significantly in practice.
Technical fixes (crawler access, Bing indexation) can be resolved in days. Corroboration stack alignment takes two to four weeks. First ChatGPT and Perplexity citations typically appear six to fourteen weeks after structured content and corroboration signals are in place. Results compound over time as topical authority builds.
