AI Search Visibility

Is your business invisible
to AI search?

Right now, potential customers are asking ChatGPT who to call for your services. If your business isn't appearing in those answers, you're losing enquiries to competitors who are. Submit your domain and we'll run a free preliminary check. We'll identify what's blocking AI from seeing you and give you an honest view on whether a full audit would deliver a return.

Understanding the Change

Search has been reinvented.
Your strategy hasn't.

The era of ten blue links is ending. AI now synthesises answers from 2–7 trusted sources. If you're not one of them, your competitor is.

One Synthesised Answer

AI reads the web, selects the most authoritative sources, and delivers a single answer with citations.

"For home appliances in the UK, AO.com is widely regarded as the most trusted specialist retailer[1], while Currys offers the broadest range across electronics and appliances[2]. John Lewis provides premium options with a price-match guarantee[3]."
ao.com — cited for trust signals & reviews
currys.co.uk — cited for product range data
johnlewis.com — cited for pricing policy

User gets one answer. If you're not cited, you don't exist.

What We Do

Traditional SEO gets you ranked.
AEO gets you featured.
GEO gets you cited by AI.

Three disciplines. One audit. You need all three working together to be visible in the places your customers are increasingly searching.

01
SEO

Search Engine Optimisation

The technical foundation. We audit crawlability, structured data, page speed, mobile experience, and content architecture — the signals that search engines and AI systems both depend on.

  • Technical crawl audit & Core Web Vitals
  • Structured data & schema deployment
  • Content architecture & internal linking
  • Mobile-first optimisation
  • Competitive benchmarking (44-item rubric)
02
AEO

Answer Engine Optimisation

Be the answer, not just a result. We structure your content for featured snippets, AI Overviews, voice search, and knowledge panels. AI Overviews already appear in 18% of Google searches — and those visitors convert at 4.4x the organic rate.

  • Answer-first content restructuring
  • FAQPage & HowTo schema
  • Featured snippet capture strategy
  • E-E-A-T signal implementation
  • Voice search optimisation
03
GEO

Generative Engine Optimisation

Get cited by ChatGPT, Perplexity, and Gemini. We make sure AI platforms can read your site, understand what you do, and choose you as their recommended source.

  • AI crawler access & robots.txt configuration
  • llms.txt deployment
  • Citation-optimised content strategy
  • Entity graph & knowledge panel building
  • AI citation monitoring & tracking
The Evidence

This isn't speculation.
It's data.

Every number is sourced. Every claim is verifiable. This is the landscape your business operates in today.

How It Works

A rigorous, auditable methodology.

Not opinions. Not guesswork. 44 pass/fail checks you can verify yourself, applied to you and four competitors.

01 — Audit

44-Item Checklist

We score your website across 5 dimensions: Technical Foundation, Structured Data, Content Depth, On-Page Optimisation, and AI Visibility. Every item is binary, every score is auditable.

02 — Benchmark

Competitive Analysis

The same 44-item audit runs on 4 of your real competitors. We calculate per-dimension deltas so you see exactly where you lead and where you trail.

03 — Test

AI Citation Testing

We query ChatGPT, Perplexity, and Gemini with real customer questions. We record who gets cited — you or your competitor. Empirical evidence, not theory.

04 — Deliver

Actionable Roadmap

A branded report with spider charts, severity-rated findings, phased roadmap with owners and costs, revenue modelling with disclosed inputs, and complete technical appendices.

See where your business stands — before your competitors do. Flat £300.

What We Find

The most common issues
hiding in plain sight.

Across our audits, the same problems appear repeatedly. Most businesses don't know they're invisible to AI — because their Google rankings look fine.

No structured data for AI extraction. Most sites have basic Organization schema for Google, but lack the entity graphs, FAQPage markup, and Review schema that AI systems use to select which sources to cite. The content exists — it's just not machine-readable.
Structured data dimension — 8 checklist items
No llms.txt, no AI crawler directives. robots.txt files typically reference Googlebot and Bingbot but make no mention of GPTBot, PerplexityBot, or ClaudeBot. Without explicit Allow directives, AI platforms have no signal that the site wants to be included in AI-generated answers.
AI Visibility dimension — 10 checklist items
The Cost of Waiting

AI citation authority compounds.
Every month you wait, the gap widens.

Evidence suggests that once an AI system begins citing a source for a given topic, it tends to favour that source across related queries. Early optimisation builds a position that is harder to displace.

3 Months

A competitor fixes their AI access first

They accumulate 3 months of citation authority you can't recover. Based on 527% year-on-year growth in AI referral traffic (Semrush, H1 2025), the compounding effect is real and measurable.

6 Months

AI shopping features go mainstream

ChatGPT Instant Checkout and Google AI Mode become primary discovery channels. Your product catalogue is invisible because AI crawlers still can't read it. Competitors are being recommended by default.

12 Months

The window closes

Rivals have 12 months of citation history, optimised content, and established AI platform trust. The cost of achieving the same competitive position is substantially higher (Visibll projection).

"AI-referred sessions grew 527% year-on-year. This is not a trend you can afford to observe from the sidelines."

If you've ever typed a question into ChatGPT or Perplexity and seen a competitor's name appear in the answer while yours didn't, you've experienced the problem directly. It's not random. It's the result of specific, fixable gaps that most UK businesses don't know they have, and that their web agencies aren't looking for.

How does AI citation actually work?

AI platforms like ChatGPT, Perplexity, and Google's AI Overviews draw on a combination of their training data and, for newer systems, real-time retrieval from indexed sources. In both cases, the same principle applies: if an AI platform can't read your site, you don't exist in its world.

The crawlers AI platforms use are entirely separate to Googlebot. A site can rank on page one of Google and be completely invisible to AI search, because the two systems are configured independently. Most businesses, and most web agencies, don't realise this distinction exists until it shows up in a competitor being recommended instead of them.

Why are most UK businesses invisible to AI search?

Across our audits, the same categories of issue appear repeatedly. They are not obscure technical problems: they are configuration and content gaps that accumulate quietly while a business focuses on its Google presence. The most common is a security configuration that was never intended to affect AI, but does.

What makes these gaps commercially significant is not their technical complexity — most are fixable in days. It's that they are invisible from the outside. Traffic looks normal. Google rankings look fine. There's no warning that an entire search channel is returning nothing for your business.

How is AI visibility different from SEO?

Your existing SEO investment is not wasted. Strong technical foundations, fast load times, and established domain authority all carry over. But AI citation requires an additional layer that standard SEO work doesn't cover, and that most SEO tools don't measure. Research from Princeton and IIT Delhi (ACM SIGKDD 2024) found that content optimised for AI citation achieves 30–40% higher visibility in AI-generated responses.

What does the free domain check tell you?

Before you commit to anything, we run a free check against your domain. We look at whether AI platforms can access your site at all — the single most common failure point — and send you the findings directly. Pass or fail, with the specific issue identified if there is one. It takes us a few working days and costs you nothing.

If the free check surfaces a problem, that finding alone is worth having. You can take it to your web team and act on it without ever commissioning a full audit. If the check comes back clean, we'll give you an honest assessment of whether the full audit would move the needle for your business.

The full AI visibility audit is a flat £300. No retainer. No upsell. A report with competitor benchmarks, severity-rated findings, and an implementation roadmap. Understand the gap first, then decide what to fix.

Common Questions

Frequently asked.

What is Generative Engine Optimisation (GEO)?

GEO is the practice of making your business the source that ChatGPT, Perplexity, and Gemini cite when users ask questions in your space. It involves making your content readable by AI platforms, structuring it so AI can extract clear answers, and building the trust signals that make AI choose you over competitors. Research from Princeton and IIT Delhi (ACM SIGKDD 2024) found that optimised content achieves 30–40% higher visibility in AI responses.

What is Answer Engine Optimisation (AEO)?

AEO structures your content so that AI-powered answer systems — Google AI Overviews, featured snippets, voice assistants, and knowledge panels — select your content as their cited source. In practice, this means writing content that directly answers the question a searcher is asking, with structured data that helps AI identify your answer. AI Overviews now appear in approximately 18% of Google searches (Similarweb, 2025), and AI-referred visitors convert at 4.4x the rate of organic search visitors (Semrush, 2025).

Why is AI search visibility important?

Over 800 million people use ChatGPT weekly (OpenAI, March 2025), and AI-referred sessions grew 527% year-on-year (Semrush, H1 2025). AI-referred visitors convert at 4.4x the rate of organic search visitors, with ChatGPT referrals converting at 15.9% versus 1.76% for Google organic (Seer Interactive, 2025). If AI crawlers cannot read your website, you are invisible to this fastest-growing search channel.

How does the Visibll audit work?

We score your website on 44 pass/fail checks across five areas: technical foundations, structured data, content quality, on-page SEO, and AI visibility. The same audit runs on 4 of your real competitors so you can see exactly where you lead and trail. We also test AI citations empirically — querying ChatGPT, Perplexity, and Gemini with real customer questions to record who gets cited.

What is llms.txt?

llms.txt is an emerging convention — a file placed at the root of your website (similar to robots.txt) that provides AI systems with a curated, machine-readable index of your most important content. It tells AI platforms which pages matter most, what your business does, and how to accurately represent your brand. While adoption is early, it is a low-cost signal that positions sites for AI discovery.
