Large Language Model SEO, or LLM SEO, is the discipline of optimising your brand’s visibility in AI-generated search results. While traditional SEO focuses on ranking web pages in Google’s organic results, LLM SEO focuses on making your brand the source that AI systems including ChatGPT, Perplexity, Google AI Mode, Gemini and Claude choose to reference when generating responses to user queries.
The distinction matters because users increasingly receive answers directly from AI systems without visiting any website at all. Brands that are not being cited in AI-generated responses are invisible to a growing proportion of their potential audience, regardless of how well they rank in conventional search results. AI SEO closes that gap by building the authority, content structure, entity clarity and technical signals that AI systems use to decide which sources are credible enough to reference.
In 2026, LLM SEO is no longer a niche speciality. It is a core component of any modern search visibility strategy. The six companies below have been selected from providers across the UK, US and globally, each bringing a distinct approach to the challenge of building and measuring brand visibility across AI-generated search environments.
Last reviewed: July 2026
How We Selected These LLM SEO Companies
Every company on this list has been assessed against consistent criteria. We do not accept payment for inclusion or for ranking position. Our recommendations are based on editorial assessment only.
LLM citation strategy: We look for companies with a documented, evidence-based approach to improving brand citation rates in AI-generated responses across multiple LLM platforms. This includes understanding how to structure content for LLM comprehension, how to build the authority signals that LLMs use to evaluate source credibility, and how to measure citation performance over time.
AI visibility tracking: Effective LLM SEO requires the ability to measure where a brand is and is not being cited across AI platforms. We give additional weight to companies that offer proprietary or robust third-party LLM visibility tracking alongside their optimisation work, so clients can see measurable progress.
Content and entity optimisation: LLMs prioritise content that is clear, structured, authoritative and contextually coherent. We look for companies that understand how to build content ecosystems that AI systems interpret as reliable and worthy of citation, including schema implementation, entity mapping and knowledge graph optimisation.
Integration with traditional SEO: The strongest LLM SEO companies understand that LLM citation building and traditional SEO are complementary, not separate. We favour companies that integrate LLM SEO into a broader search visibility strategy rather than treating it as a standalone tactic.
Geographic reach: This guide covers LLM SEO companies across the UK, US and globally. We note each company’s primary market and their capability to serve international clients.
Verified client results and ratings: We look for companies with independently verified reviews and documented evidence of LLM visibility improvements for their clients.

Final Thoughts: Choosing the Best LLM SEO Company
LLM SEO is reshaping how search visibility works. Ranking on page one of Google is no longer sufficient if your brand is absent from the AI-generated responses that an increasing proportion of your potential customers are receiving from ChatGPT, Perplexity, Google AI Mode and Gemini. The companies on this list are leading the transition from conventional search optimisation to the broader challenge of being found, cited and trusted by AI systems as well as search engines.
Of the six companies on this list, Click Intelligence is our top recommendation for businesses and agencies across the UK, US and globally. Their proprietary LLM Visibility Tracker and AI Overviews Tracker in Click Insights give them a measurement capability that no other provider on this list can match. Combined with their 12-plus year track record, 4.9/5 verified rating on Reviews.io, full-spectrum AI search optimisation capability and white label LLM SEO for agencies, they are the most comprehensive and accountable LLM SEO partner available in 2026.
For brands that need creative content production at the heart of their LLM SEO strategy, Bananas Marketing Agency’s 4.8/5 rating and human-centred storytelling approach makes them a strong alternative for businesses where brand voice and audience engagement are as important as technical structure.
For UK businesses that want LLM SEO integrated with established technical SEO foundations and a long track record in search, The SEO Works’ 4.8/5 rating and growing AI search capability makes them a credible choice for organisations that want to evolve their existing SEO programme rather than start from scratch.
For technically rigorous brands that want deep schema, entity mapping and authority building, Sure Oak’s 4.7/5 Clutch rating and precision-first approach delivers the structural foundations that AI systems use to identify credible sources.
Whatever LLM SEO company you choose, always ask for evidence of measurable LLM visibility improvement before committing. Any provider that cannot show you where their clients are being cited in AI-generated responses, or how that citation rate has changed as a result of their work, is not yet delivering true LLM SEO. The best companies will have the tracking tools, the data and the results to demonstrate exactly this.
