LLM SEO (SEO for large language models) is the work of getting your brand mentioned, recommended and cited when people ask AI assistants such as ChatGPT, Gemini, Claude and Perplexity for advice. Assistants answer from two sources: what the model learned in training, and what it finds by searching the web in real time. You influence both by being accessible to AI crawlers, publishing clear and specific pages, keeping your brand details consistent everywhere, earning mentions on trusted sites, and tracking a fixed set of buyer questions every month.
How AI assistants decide which brands to mention
Two paths into an AI answer, training and live retrieval, meeting at an answer that names 3 to 5 brands. 3 levels, top to bottom:
- Path 1, training: slow to change; the web, books and other text, model training, general knowledge of brands
- Path 2, live retrieval: changes quickly; the buyer’s question, web search by the assistant, pages it can read and trust, sources cited in the answer
- the answer names 3 to 5 brands
Training knowledge reflects how often and how consistently your brand appears across the web: news, industry sites, directories, reviews, forums and your own site. It updates when models are retrained.
Live retrieval happens when the assistant searches the web to answer. It reads pages it can access, prefers clear, current and authoritative sources, and often links to them. This is where most quick wins come from.
LLM SEO, step by step
- Let AI crawlers in. Check robots.txt, your CDN and security rules for GPTBot, OAI-SearchBot, ClaudeBot, PerplexityBot and others. Blocking them removes you from live answers.
- Make content readable without JavaScript. Key text, prices or price ranges, and service details should be in the page HTML.
- Answer buyer questions on your own pages. Service, industry and location pages should say clearly what you do, for whom, where, how much it roughly costs and why you are different, with a direct answer near the top.
- Publish comparison and "best for" content. Assistants are often asked "which is best for". Honest comparison pages and clear positioning help you appear in those answers.
- Keep your brand entity consistent. The same name, description, services, locations and contact details on your site, Google Business Profile, LinkedIn, directories and review sites.
- Earn mentions on trusted sites. Industry publications, associations, partner pages, podcasts, award lists and review platforms. Assistants weigh what others say about you.
- Collect reviews. Reviews on Google and industry platforms shape how assistants describe service businesses.
- Track and iterate. Run the same 50 to 100 buyer questions monthly across assistants, record mentions, citations and accuracy, and fix the gaps.
LLM SEO for service businesses
For agencies, clinics, law firms, consultancies, schools and other service businesses, the questions are local and specific: "best orthopedic hospital in Pune", "SEO agency for hospitals in India". Assistants lean on location pages, Google Business Profiles, reviews and directory listings. A complete, consistent local footprint matters as much as content.
LLM SEO tools: what to look for
A useful LLM SEO tool runs a fixed set of prompts across several assistants on a schedule, records which brands are mentioned and cited, tracks accuracy, compares you with named competitors, and shows trends over time. One-off checks are not enough, because answers vary between runs.

Common mistakes
- Blocking AI bots through a security plugin or CDN rule without knowing it.
- Vague service pages that never say what you do, for whom and where.
- Inconsistent profiles that give assistants conflicting facts.
- Chasing a single prompt instead of tracking a question set.
- Expecting instant changes in training data. Live retrieval moves faster; training knowledge takes months.
