Generative Engine Optimization
Your buyer asks a machine for a shortlist of three suppliers. This is the work that decides whether your name is one of them.
— 01 The shift
The answer replaced the results page.
Generative Engine Optimization (GEO) is the work of making a company readable, understandable, and citable by the systems that now answer buyers directly: ChatGPT, Perplexity, Google AI Overviews, and Copilot.
A results page shows ten links and lets the buyer choose. An answer shows three names and does the choosing. That is the whole change, and it moves the competition upstream: from being the best option among ten, to being one of the three a machine is confident enough to name.
Confidence is the operative word. An engine does not skip a company for being bad. It skips it for being unverifiable. Capabilities locked inside a PDF, certifications as a scanned image, a spec sheet that exists only as a design: none of it can be asserted, and what cannot be asserted does not get cited.
— 02 The work
Four things, in this order.
Make the site machine-readable
Rendering parity so an AI crawler sees what a browser sees, structured data on the pages that carry real specifications, and a robots policy that decides deliberately which AI crawlers are welcome rather than leaving it to a default nobody chose.
Write what can be cited
A direct answer in the first sentence, a question as the heading, and evidence instead of adjectives. Numbers with a date and a source, certifications with their validity, sectors actually served. A page of superlatives is a page an engine has no safe way to quote.
Take a dated baseline
A fixed list of the prompts your buyer would really type, run against each engine, recorded with the date, the answer, and which source was cited. Without that first snapshot there is no honest way to claim later that anything improved.
Measure the crawlers, not just the rankings
GPTBot, ClaudeBot, PerplexityBot, OAI-SearchBot and ChatGPT-User leave a trace in the server logs. That trace is the difference between believing you are visible to AI and having the evidence. It also separates a training crawl from a live retrieval triggered by a real person mid-conversation.
— 03 The limit
What nobody can promise you.
No agency can guarantee a position inside a generative engine. These systems are not deterministic: the same question asked twice can return different names, and the model behind the answer changes without notice.
What can be promised is the work and the measurement: a baseline with a date, the technical and editorial changes that make a company citable, and a repeat measurement against the same prompts. If a proposal promises you a fixed spot in ChatGPT, the problem is not the price. It is that the thing being sold does not exist.

Frequently asked questions
What is Generative Engine Optimization (GEO)?
GEO is the work of structuring a company’s content, data, and technical signals so that generative systems like ChatGPT, Perplexity, Google AI Overviews, and Copilot can find it, understand it, and cite it inside an answer. It sits alongside SEO rather than replacing it: SEO earns a click on a results page, GEO earns a mention inside an answer that may never show a link at all.
Is GEO the same as AEO or LLMO?
They describe the same underlying work. The industry has not settled on one term: GEO (Generative Engine Optimization), AEO (Answer Engine Optimization), and LLMO (Large Language Model Optimization) all mean structuring content so a machine can extract a direct answer and attribute it to your brand.
Can an agency guarantee my company appears in ChatGPT?
No, and anyone who promises it is promising something the system does not offer. Generative engines are not deterministic: the same question asked twice can return different names. What can be done is to measure where you stand today with a dated record, work on what moves it, and measure again against the same prompts.
How is GEO measured if there are no rankings?
By running a fixed list of buyer-intent prompts against each engine on a schedule and recording, with a date, whether your brand is named, how it is described, and which source was cited. Server logs add the other half: crawlers such as GPTBot, ClaudeBot, PerplexityBot, and OAI-SearchBot leave a record of what they read and when.
How long does GEO take to show results?
Faster than traditional SEO in some cases, because generative engines depend less on domain age and more on whether content is citable, but also more volatile. A realistic frame is weeks to see crawler activity change, and three to six months before citation frequency moves in a way that holds.
Find out where you stand today.
The first step is a dated baseline: the prompts your buyers actually use, run against the engines, with the answers on record. It is the only starting point that lets you prove progress later.
