AI SEO Agency London
Your competitors are already showing up in ChatGPT and Google AI Overviews. You're not. That's the gap we close.
SuperSize Digital is a London-based AI SEO agency specialising in optimising brands for AI search platforms including ChatGPT, Google Gemini, Perplexity, and Google AI Overviews. Founded by Stephen Tasker with over 15 years in search engine marketing, the agency delivers AI search optimisation alongside traditional SEO for B2B, SaaS, legal, fintech, healthcare, and ecommerce businesses. Based at 399–405 Oxford Street, Mayfair, London.
The search landscape has shifted. AI-driven search is no longer a novelty — it's a primary discovery channel. Around three in four Americans now use AI tools to search weekly (Mango Thrive, March 2026), and AI referral traffic to websites grew 527% year-on-year in the first half of 2025 (Previsible AI Traffic Report, 2025). Decision-makers are using AI platforms to research vendors, compare solutions, and shortlist providers before they ever visit your website.
If your brand isn't being cited in those AI-generated answers, you're losing deals before you know they exist. AI search optimisation is the discipline that fixes that — and it's what we do.
What Is AI SEO?
AI SEO is the practice of optimising your content, technical setup, and brand signals so that AI platforms — including ChatGPT, Google Gemini, Google AI Overviews, Perplexity, Microsoft Copilot, and Claude — cite, recommend, or mention your business when answering user queries.
Unlike traditional search engine optimisation, where the goal is to rank in a list of links, AI SEO focuses on getting your brand included in the synthesised answers AI systems generate. When a marketing director asks ChatGPT "what are the best B2B SEO agencies in London?" — the brands that appear in that response have been optimised for AI search, whether they realise it or not.
What Does GEO Stand For?
GEO stands for generative engine optimisation. It describes the same discipline as AI SEO — structuring content so that generative AI systems retrieve and cite it when assembling answers. The term was formalised by researchers at Princeton University, whose study found that targeted optimisation techniques can improve visibility in AI-generated responses by up to 40%.
What Is AEO?
AEO stands for answer engine optimisation. Originally associated with voice search and featured snippets, AEO is now largely subsumed by GEO and AI SEO, since most voice queries route through the same AI systems that power generative search. In practice, AI SEO, GEO, and AEO all describe the same goal: getting your brand into AI-generated answers.
How Is AI Search Different from a Google Search?
AI search engines don't rank pages in a list. They break a query into sub-queries, search the web for relevant passages, retrieve the best-matching content chunks, and synthesise them into a single response with citations. Your content needs to be structured for extraction — self-contained, factually dense, and easy for an AI model to understand in isolation — not just optimised for keywords and backlinks.
Why Does AI Search Optimisation Matter?
AI search is no longer an experiment. ChatGPT alone processes over 2 billion queries daily and has surpassed 883 million monthly users as of January 2026. Google AI Overviews now appear in approximately 25% of all searches. When those AI Overviews appear, click-through rates on traditional organic results drop from 15% to 8%.
Visibility Where Decisions Are Made
AI search is increasingly where B2B decision-makers begin their research. Being cited in a ChatGPT or Perplexity response carries an implicit endorsement that no traditional organic listing can match. Visitors arriving from AI search convert at approximately 4.4 times the rate of traditional organic visitors, because they arrive further along the decision-making process.
Competitive Advantage While It's Still Available
Most businesses — including most SEO agencies — haven't optimised for AI search yet. Only 22% of marketers are actively tracking AI visibility. The brands that invest now build citation authority that compounds over time, just as domain authority did in the early days of traditional SEO. This window won't stay open.
Protect Your Existing Organic Traffic
AI Overviews are appearing above traditional search results for a growing number of queries. If you're ranking on page one but not being cited in the AI Overview above it, your click-through rate is already declining. Research from Ahrefs found that AI Overviews reduce clicks to the top-ranking page by 58%.
How Do AI Search Engines Decide What to Cite?
Understanding how AI engines select sources is the difference between an AI SEO strategy that works and one that's just guesswork.
When someone asks an AI tool a question, the system doesn't simply search for matching keywords. It uses a process called retrieval-augmented generation. The AI breaks the query into sub-queries, searches the web for relevant passages, retrieves the best-matching content chunks, and then synthesises those passages into a coherent answer — citing the sources it drew from.
This means AI platforms aren't reading your whole page. They're extracting specific passages. The content that gets cited tends to share specific characteristics: it's factually dense rather than vague, self-contained rather than reliant on surrounding context, well-structured with clear headings and definitions, recently updated rather than stale, and published by a source with strong entity signals — meaning the AI can verify who wrote it and why they're credible.
What doesn't get cited: marketing fluff with no specific claims. Content that opens with "in today's fast-paced world" and never gets to a concrete point. Pages that haven't been updated in over three months. Sites that block AI crawlers — which includes many sites using Cloudflare's default settings, which changed in 2025 to block AI bots automatically.
The critical difference from traditional SEO: AI search results value factual density over keyword density, structured data over backlink volume, and content freshness over domain age. Traditional search engine optimisation builds the foundation — but AI search optimisation adds specific requirements that traditional SEO alone doesn't address.
What Does Our AI SEO Service Include?
Every AI SEO campaign we run follows a structured process. We don't bolt AI optimisation onto an existing SEO strategy as an afterthought — we build it in from the start.
AI Search Audit
We assess your current visibility across ChatGPT, Gemini, Perplexity, and Google AI Overviews. Where are your competitors being cited and you're not? We review your robots.txt for AI crawler blocks, audit your schema markup, assess content structure for AI extractability, and check for Cloudflare or server-level bot restrictions. You get a clear report showing exactly where you stand and what to fix first.
Content Optimisation for AI Citation
We restructure your existing content for AI extraction: self-contained paragraphs that make sense when pulled out of context, question-format headings that mirror actual search queries, factual density in every section, and definition-lead architecture that gives AI models a clean passage to cite.
Technical SEO for AI Crawlers
AI bots need to be able to crawl and understand your site — and the bar is higher than for Google. We check for Cloudflare blocks, robots.txt exclusions, and JavaScript rendering issues. We implement llms.txt files and deploy schema stacking — Organization, FAQPage, Article, and Service markup — so AI platforms can categorise and extract your content accurately.
Digital PR & Citation Building
AI models don't just read your website. They pull from industry publications, directories, comparison sites, Reddit, LinkedIn, and news sources. Our digital PR and citation building focuses on earning brand mentions in the specific sources AI platforms reference most. This isn't just link building — it's building the third-party consensus that makes AI engines trust your brand enough to cite it.
Monitoring & Reporting
We track AI citation frequency, brand mention sentiment, and share of voice across AI platforms — alongside traditional SEO metrics like rankings, traffic, and conversions. Monthly reporting shows you exactly where you're being cited, how often, and what's changing. You'll see which AI platforms mention you, which queries trigger citations, and where the gaps remain.
How Is AI SEO Different from Traditional SEO?
Traditional SEO
Focuses on keywords, backlinks, technical health, and ranking positions in a list of links.
Asks: "Does this page rank?"
Optimises for ranking positions on Google's search results pages.
AI SEO
Focuses on factual density, self-contained passages, schema markup, third-party brand mentions, content freshness, and entity authority.
Asks: "Would an AI model cite this passage as a credible source?"
Optimises for inclusion and citation in AI-generated answers.
Strong traditional SEO is the foundation AI visibility is built on. Content that ranks well on Google is more likely to be referenced by AI models — research from Ahrefs found that over 76% of URLs cited in AI Overviews also rank in Google's top 10. The smartest approach combines both — and that's how every campaign we run is built.

AI SEO Frequently Asked Questions
What does an AI SEO agency do?
An AI SEO agency optimises your content, technical setup, and brand signals so that AI search platforms like ChatGPT, Gemini, and Perplexity cite your business in their responses. This includes content restructuring, schema markup, technical SEO for AI crawlers, and digital PR for citation building.
Is AI SEO the same as GEO?
Yes. GEO (generative engine optimisation) and AI SEO describe the same discipline — optimising for inclusion in AI-generated search results rather than traditional search engine rankings. AEO (answer engine optimisation) covers the same goal.
Do I still need traditional SEO if I invest in AI SEO?
Yes. Traditional search engine optimisation is the foundation AI visibility is built on. Content that ranks well on Google is significantly more likely to be cited by AI models. The most effective SEO strategies combine both traditional and AI-focused optimisation.
How do you measure AI SEO performance?
We track AI citation frequency, brand mention sentiment, share of voice across AI platforms, and referral traffic from AI sources — reported alongside traditional SEO service metrics like rankings, organic traffic, and conversions.
How long does AI SEO take to show results?
AI search platforms refresh their citation sources frequently. Well-optimised content can begin appearing in AI responses within weeks. Building sustained citation authority typically takes two to four months of consistent work — faster than traditional SEO, but it requires ongoing content freshness and monitoring.
