Why us

Be the business the AI recommends

Search is moving into AI answers

More searches now end inside an AI-generated answer than on a traditional results page. The tool reads the question, then names a few businesses it trusts rather than showing ten blue links.

That changes the game. If the AI does not know and trust your business, you are invisible at the exact moment a customer is choosing, however well you rank in classic search.

Authority and clarity win

AI engines recommend the businesses they understand and trust. That comes from authority, citations from other sites, clear structured information and genuinely useful content.

So that is what we build. We make your business legible and credible to the AI engines, so they can find you, understand what you do and feel confident putting you forward.

Honest about a new field

AI search is new and changing fast. Nobody controls how ChatGPT or AI Overviews choose what to say, so anyone promising guaranteed placement is not being straight with you.

We work differently. You get realistic expectations, measurement of how your AI visibility actually changes, with flexible terms rather than a guarantee nobody can keep.

What we do

Four areas, one programme

01

AI visibility audit and strategy

Know where you stand. We check whether you appear across ChatGPT, Google AI Overviews, Gemini and Perplexity, then build a clear plan to improve it.

02

Authority and citations

Earn the trust. AI engines lean on authority and citations from credible sources. We build the brand mentions, references and signals that make them confident in your business.

03

Content and structured data

Be understood. We give your site the depth, clarity and structured data the AI engines need to read what you do, who you serve and why you can be recommended.

04

Measurement

Track real visibility. We measure how often and how well the AI engines surface your business, so progress is visible rather than guessed at, with the work staying accountable.

How it works

A clear, four-step process with no mystery and no jargon.

01

Free AI visibility audit

Frequently asked

Generative engine optimisation questions

What is generative engine optimisation?
Generative engine optimisation (GEO) is the work of getting your business found, cited and recommended inside the answers that AI search tools generate. When someone asks ChatGPT, Google AI Overviews, Gemini or Perplexity for a recommendation, those tools pull together an answer from sources they trust, rather than showing a list of links. GEO is about becoming one of the businesses they trust and name. It draws on authority, citations, structured data, content depth and clear, credible information, so the AI engines understand what you do and feel confident putting you forward. It overlaps with SEO but is not the same, because the goal is being included in a generated answer rather than ranking in a list of blue links.
How is GEO different from SEO?
Traditional SEO aims to rank your pages in a list of search results, where the user then clicks through. GEO aims to get your business named and cited inside an AI-generated answer, where there may be no list to click at all. The underlying signals overlap, since authority, useful content and structured data help with both, though the target is different. With SEO you want position one on the page. With GEO you want to be the business the AI recommends when it writes its answer. The two work best together: strong SEO foundations support GEO, while GEO captures the growing share of searches that now end inside an AI answer rather than on a results page.
How much does GEO cost?
We offer three monthly packages: Starter at £350, Growth at £750 and Full at £1550 a month, so you can pick the level that fits your business and how competitive your market is. A smaller business in a quieter niche usually starts on Starter, while a business in a competitive national market needs the Full package. We keep terms flexible with no long tie-in, then start with a free AI visibility audit so you can see where you currently appear across the AI engines and which package fits before you commit. If your needs sit between tiers or you want something tailored, we can shape a plan around them. GEO is an investment that compounds as the AI engines learn to trust your business.
How long until GEO works?
Usually a few months rather than weeks, with the effect building gradually. AI engines need time to find, trust and start citing your business, which depends on the authority and signals you build over the period. Most businesses see meaningful progress over three to six months of consistent work, with results becoming more durable the longer it runs. AI search is also new and changing quickly, so part of the work is keeping pace as the engines evolve. We are honest about this up front: nobody can guarantee that a specific tool will recommend you by a specific date, so we focus on steady, sustainable progress measured against your visibility in AI answers.
Can you guarantee my business appears in ChatGPT or AI Overviews?
No, you should be cautious of anyone who does. We do not control ChatGPT, Google AI Overviews, Gemini or Perplexity, while how they generate answers changes constantly, so guaranteed placement is not something any honest agency can promise. What we can do is build the authority, citations, structured data and credible content that genuinely improve your chances of being found and recommended, then measure how your visibility changes over time. That is a far more honest and durable approach than a guarantee that cannot be kept. The aim is steady, measurable improvement in how often the AI engines surface your business, not a promise nobody can stand behind.
