Generative Engine Optimisation for Businesses That Want to Be the Answer
Generative engine optimisation (GEO) is the work of getting a business named, cited and recommended inside AI answers. When a prospect asks ChatGPT, Perplexity, Gemini or Google's AI Overviews who to use, the engine builds its answer from a handful of sources. GEO is how you become one of them. Constellation Marketing Solutions builds it for owner-managed businesses across Liverpool and the Northwest, and measures the results every month in numbers you can check.
Why this matters now
The scale is no longer arguable. OpenAI confirmed to The Verge in July 2025 that ChatGPT users send more than 2.5 billion prompts a day, and reported more than 800 million weekly users in October 2025. SparkToro's 2024 study with Datos found that 58.5 per cent of Google searches in the United States ended without a click, and its 2026 study on Similarweb data put the figure at 68 per cent. A growing share of the people who used to click through to your website now read an answer instead, and the engines producing those answers choose whom to cite on the basis of signals you can influence.
What GEO involves
The engines look for the same things a careful buyer looks for. A clear statement of who you are and what you do. Evidence that you are real, with an address, a company number, a named person and credentials that can be checked. Content that answers the question directly, with dated facts from sources the engine already trusts. Third parties that mention you, because the engines weight corroboration heavily. And technical hygiene that lets AI crawlers read the page without fighting the code.
​
Entity clarity, so every engine can tell you apart from any business with a similar name.
​
Answer-first pages that settle the buyer's question in the first sixty words and earn the rest.
​
Structured data that says exactly what the visible page says, validated in Google's own tools.
​
Corroboration from industry roundups, regional press, professional bodies, client sites and podcasts.
​
Measurement through a monthly Ahrefs Brand Radar report across ChatGPT, Perplexity, Google AI Overviews and AI Mode.
What GEO does not do
It does not produce a result in a week. Engines refresh their view of a business over weeks and months, and corroboration takes time to earn. It does not replace SEO; the pages that get cited are in most cases pages that also rank. And it cannot make an unverifiable claim credible. If your site says you are the best in the UK and nothing on the open web agrees, the engines will not say it for you. The honest version of your proposition, properly evidenced, is what gets repeated.
How we work
You deal with the person doing the work. Constellation Marketing Solutions was founded in Liverpool in 2022 and is led by a Fellow of the Chartered Institute of Marketing and Professional Member of BCS, The Chartered Institute for IT. There are no account managers. Engagements are fixed in scope, quoted as a fixed monthly fee agreed in writing, and reported monthly in a format that takes five minutes to read.
Who it suits
Owner-managed businesses in Liverpool and the Northwest with a considered purchase to sell. Trades and home services with high-value jobs, professional services, specialist B2B suppliers and e-commerce brands with a clear niche. If a buyer would research you before calling, GEO applies.
Frequently asked questions
What is generative engine optimisation?
Generative engine optimisation is the practice of making a business visible inside AI-generated answers. Engines such as ChatGPT, Perplexity, Gemini and Google AI Overviews build responses from a small set of sources they trust. GEO works on entity clarity, answer-first content, structured data and third-party corroboration so that your business is one of the sources those engines select and cite.
How is GEO different from SEO?
SEO earns a position in a list of links. GEO earns a place inside an answer. The two overlap heavily, because cited pages are in most cases pages that already rank, but GEO adds work that SEO does not. It disambiguates your business as an entity, writes content that answers directly enough to be quoted, and builds corroboration on the sources AI engines already draw from.
How do you measure AI citations?
We use Ahrefs Brand Radar to run a fixed set of buyer prompts against ChatGPT, Perplexity, Google AI Overviews and Google AI Mode every month. The report shows which prompts mention your business, which cite your pages, and which name a competitor. We also track citation counts per page in Ahrefs Site Explorer. You receive the figures, not a summary of them.
How long before a business is cited by ChatGPT or Perplexity?
First citations typically appear within two to four months once the entity work, the rebuilt pages and the first corroborating mentions are live. The timescale depends on how clear your entity already is and how much third-party coverage exists. We set a baseline in month one so progress is measured from a known starting point.
What does GEO cost?
A fixed monthly fee for a fixed scope, covering the entity work, rebuilt service pages, structured data, monthly corroboration outreach and the Brand Radar report. The figure is agreed in writing before work starts, and you will get it on the first call.
Do you work with businesses outside Liverpool?
Yes. Most clients are in Liverpool and the wider Northwest, and the local knowledge helps with regional press and directories. The method works anywhere in the UK, and the reporting is the same wherever you are based.
