As more people turn to AI tools like ChatGPT for answers, recommendations, and even shopping decisions, the way brands are discovered online is shifting fundamentally. This isn’t just another search trend you can afford to monitor from the sidelines – it’s a complete transformation of how customers find and evaluate products and services. When someone asks ChatGPT “what’s the best CRM for small businesses?” or “where should I buy running shoes in London?”, there’s often just one brand mentioned in the response. If that’s not you, you’ve lost the opportunity entirely, with no “position #2” to fall back on.
This isn’t about traditional rankings anymore – it’s about being part of the conversation inside AI platforms. And here’s the reality most businesses are missing: the brands securing these AI citations today are building authority that compounds over time. AI systems learn which sources to trust and cite based on patterns that reinforce – early movers are establishing themselves as the default recommendations in their categories while competitors are still debating whether AI search matters.
That’s where ChatGPT and AI search optimisation comes in. By tailoring your content, data, and technical setup for large language models (LLMs), your business can be cited, recommended, and surfaced in generative responses. To help you get started, we’ve rounded up the 7 top UK agencies leading the charge in ChatGPT & AI search optimisation for 2026 – specialists who’ve already cracked the code on securing AI citations while most agencies are still figuring out the basics.

How ChatGPT Decides Which Brands to Recommend (and How to Influence It)
Understanding how AI systems like ChatGPT select which brands to cite is crucial for effective optimisation. Unlike traditional search engines that primarily rely on backlinks and keyword matching, large language models make recommendations based on the patterns they’ve learned from their training data and the structure of information available online. They favour sources that provide clear, comprehensive answers in conversational formats, have strong entity recognition (meaning the AI clearly understands what your brand represents), and demonstrate authority signals through consistent mentions across reputable sources. This means traditional SEO tactics like keyword density are far less important than creating content that directly answers questions in formats AI can easily parse and synthesise.
The practical implications are significant. To increase your chances of being cited by ChatGPT, you need structured content that mirrors how people actually ask questions – not just optimised blog posts but genuine Q&A formats, comprehensive guides that cover topics thoroughly rather than superficially, and clear entity markup that helps AI systems understand your business relationships and expertise areas. You also need consistent NAP (name, address, phone) information across the web, authoritative mentions in contexts where AI models learn about your industry, and content that demonstrates genuine expertise rather than just targeting keywords. Agencies like ClickSlice have developed systematic approaches to ChatGPT optimisation that address all these factors – they’re not just hoping for citations, they’re engineering content and technical structures specifically designed to make your brand the obvious choice when AI systems generate recommendations in your category.
FAQs
What is ChatGPT optimisation?
ChatGPT optimisation ensures your content is discoverable and cited within AI-generated answers. It focuses on conversational intent, structured content, and visibility inside large language models.
Why does ChatGPT optimisation matter for businesses?
AI tools like ChatGPT are increasingly used for product recommendations, local searches, and service comparisons. If your business isn’t represented, you’re losing customers to competitors who are.
How is ChatGPT optimisation different from SEO?
Traditional SEO targets Google SERPs, while ChatGPT optimisation ensures your brand is surfaced in generative answers. It often requires different formats – like FAQs, conversational content, and structured data.
Do all industries need ChatGPT optimisation?
Industries where users seek recommendations – such as eCommerce, SaaS, and services – benefit the most. But as AI adoption grows, nearly all businesses will need to prepare for this shift.
How long does it take to see results?
Timelines vary, but many brands notice increased mentions in generative answers within 3–6 months. Ongoing optimisation is key, as AI models are constantly evolving.
What’s the typical cost of ChatGPT optimisation in the UK?
Most agencies charge from £1,500/month upwards, depending on complexity and scale. Enterprise-level projects with content overhauls or multi-language support will cost more.

Choosing the right partner comes down to proven capability in securing ChatGPT citations and AI recommendations, not just general AI awareness. Ask potential agencies for specific examples of clients being cited in ChatGPT responses, case studies showing increased brand mentions in AI-generated answers, and their systematic approach to content formatting, entity optimisation, and structured data for AI consumption. The best agencies will show you concrete proof they’re delivering results today, including before-and-after examples of AI citation frequency for their clients.
ChatGPT optimisation isn’t optional for businesses that want to remain visible as search continues its rapid evolution. The brands that will dominate their categories in the next 2-3 years are the ones investing in AI search optimisation now, building the authority and technical infrastructure that makes them the default recommendations when millions of people ask AI systems for advice every day. Choose an agency that treats ChatGPT optimisation as a core expertise rather than an experimental add-on, operates with full transparency about AI citation performance, and has the technical and strategic depth to keep evolving strategies as AI search continues its rapid development. When you find that partner, you’ll be positioned to win the AI search revolution while your competitors are still optimising for the old world of blue links and keyword rankings.
