What does a generative engine optimization agency do?

A GEO agency makes your business the source AI assistants cite when buyers ask, then proves it with a number. In practice that means shipping the inputs that earn citations, citable page copy, schema markup, and an llms.txt summary, confirming AI crawlers can reach your pages, and building consistent brand-entity signals across the web. The part that separates a real GEO agency from a rebranded SEO shop is measurement: it tracks your citation rate across ChatGPT, Perplexity, and Google AI Overviews over time and against named competitors, not just where you rank in Google's blue links. The output you are buying is presence inside AI answers.

How is a GEO agency different from an SEO agency?

They share groundwork and aim at different targets. Both want a fast, crawlable, well-structured site, so the technical base overlaps. The difference is the surface each one optimizes and the metric each one reports. An SEO agency works to rank your page in Google's ten blue links and reports position and clicks. A GEO agency works to get your brand cited inside AI answers and reports citation rate across engines. The trap is an SEO agency that added GEO to its pitch but still only measures rankings. If the reporting is all positions and no citations, you are buying SEO with a new label.

How much does a GEO agency cost?

It depends on scope, so treat any flat number with suspicion. Cost scales with how many pages need rewriting for citation, how many languages you operate in, how competitive your buyer questions are, and whether you need a one-time foundation or ongoing monthly tracking. A small foundational engagement is very different from a multilingual retainer with monthly citation reporting across engines and competitors. The honest answer any good agency gives is that it prices after a scoping conversation, and commits the number in writing before you sign. Ask for that, not a sticker price.

What questions should I ask a GEO agency before hiring?

Ask five things. One, how do you measure success, and will I see citation rate across more than one AI engine, not just Google rank? Two, what exactly do you ship, meaning schema, llms.txt, and citable copy, and who writes it? Three, how do you handle AI-crawler access and rendering? Four, can you show your own results, since an agency that cannot make itself cited is a warning. Five, what does reporting look like month to month, and is it tracked against named competitors? Clear answers to these separate a real practice from a rebranded one.

Can I do GEO myself instead of hiring an agency?

Yes, especially if your site is small. You can ship citable passages, schema, and an llms.txt file yourself, then check citations by asking ChatGPT and Perplexity your top buyer questions and noting whether you are named. That manual loop is free and teaches you what an agency automates. An agency earns its cost once the work needs real, sustained investment, when you have many pages, more than one language, or need citation rate tracked across engines and competitors every month. Size the gap first, then decide whether to hire.

How to Choose a Generative Engine Optimization (GEO) Agency

A buyer's guide to hiring a GEO agency: what one actually does, five things to verify, the questions to ask, and the red flags that mean it is an SEO agency in disguise.

TL;DR

Choosing a generative engine optimization (GEO) agency, one that structures your site so AI assistants cite it, comes down to one test: does it measure whether ChatGPT, Perplexity, and Google AI Overviews cite you, or does it just report Google rankings with a GEO label? A real GEO agency ships the inputs that earn citations, citable copy, schema, and an llms.txt summary, confirms AI crawlers can reach you, and tracks citation rate over time, across engines, and against named competitors. Before hiring, verify five things, ask five questions on the first call, and watch for the biggest red flag: an SEO shop that added GEO to its pitch but still only measures rank. This guide gives you the buyer's checklist, the questions, and the red flags, so you can grade any agency, including the one you are reading now, and decide whether an agency, a tool, or doing it yourself fits your stage.

What a generative engine optimization agency actually does

A generative engine optimization (GEO) agency structures your site so AI assistants cite it when buyers ask a question. That is a different job from ranking a page in Google, and the difference is the whole reason the category exists.

The confusion is understandable, because the groundwork overlaps. A fast, crawlable, well-structured site helps both traditional search and AI citations, so much of the technical work looks the same. What separates a GEO agency is what it optimizes for and what it puts on the monthly report.

What a GEO agency does vs a traditional SEO agency. A traditional SEO agency works to place your page in Google's ten blue links, and it reports keyword positions, backlinks, and traffic. A generative engine optimization agency works to get your brand named inside AI answers, and it reports citation rate: whether ChatGPT, Perplexity, and Google AI Overviews cite you, in what context, and against which competitors. The inputs overlap, because a schema-rich, crawlable, well-linked site feeds both surfaces, but the metric diverges. SEO measures the ranking and the click; GEO measures the citation inside a generated answer. The two can even move apart, as when a page holds a strong position while an AI Overview answers the question above it and takes the attention. If an agency's reporting shows only rankings, it is measuring the surface you were not worried about.

Five things to verify before you hire a GEO agency

Skip the pitch deck and check five concrete things. They predict whether an agency will move your citation rate or just bill you.

Five criteria for choosing a GEO agency. Verify these before you sign. One, it measures citation rate across AI engines, not just Google rank, because that is the surface GEO is meant to win. Two, it covers more than one engine, since ChatGPT, Perplexity, Gemini, and Google AI Overviews answer differently and one of them is a partial view. Three, it ships the inputs that earn citations, meaning citable page copy, schema markup, and an llms.txt summary, and it writes them rather than outsourcing the thinking. Four, it reports honestly, with share of voice against named competitors and stated variance instead of a vanity score. Five, it can show its own results, because an agency that has not made itself cited by AI is selling a method it has not proven. An agency that passes all five is rare; most fail on multi-engine measurement or on showing their own work.

Treat any agency that cannot speak to all five as a maybe, not a yes.

Questions to ask on the first call

Bring these to the discovery call. Vague answers are an answer.

How do you measure success? You want citation rate across more than one AI engine, not only a Google ranking report.
What exactly do you ship, and who writes it? Schema, llms.txt, and citable copy should be named, and the writing should not be quietly outsourced.
How do you handle AI-crawler access? They should talk about GPTBot, ClaudeBot, PerplexityBot, robots rules, and rendering without prompting.
Can you show your own results? Ask where AI assistants cite them today.
What does month-to-month reporting look like? It should track your citation rate against named competitors, not just log activity.

Red flags: the SEO agency wearing a GEO badge

The most common trap is not a bad agency. It is a competent SEO agency that added the word GEO to its homepage and changed nothing underneath.

Red flags when hiring a GEO agency. Four signals mean an agency is selling SEO with a new label. First, the reporting is all rankings and clicks, with no citation-rate metric anywhere, so you never learn whether AI names you. Second, it measures only Google, ignoring ChatGPT, Perplexity, and Gemini as if AI search were a single surface. Third, it promises "guaranteed AI Overview placement" or a specific citation count, which no one can honestly guarantee given how much AI answers vary run to run. Fourth, it cannot show its own AI citations, or dodges the question, which means it is selling a practice it has not run on itself. A fifth, softer flag: the proposal is a spec sheet of deliverables with no metric attached to any of them. If success is not defined as a number you will watch, there is nothing to hold the agency to.

Agency vs tool vs DIY: which fits your stage

Hiring an agency is not always the right first move, and a good agency will tell you so.

If your site is small, start by hand. Ship an llms.txt, add schema, rewrite your top pages into citable answers, and check citations yourself. A tool becomes worth it when manual tracking breaks down across many pages or engines, which is the trade-off our guide on the best generative engine optimization tools walks through. If you want the whole DIY loop, our step-by-step GEO guide is the playbook.

An agency earns its cost a step later, when the inputs need real, sustained investment and have to stay shipped. Schema, llms.txt, citable copy, and off-site entity signals all need to move together and be maintained, not set once and forgotten.

How W2B runs GEO

We built our own generative engine optimization service to pass the five checks above. Every engagement opens with a scored AI-visibility audit, ships the inputs, then tracks citation rate across ChatGPT, Perplexity, and Gemini month over month, against your named competitors. We work bilingually in English and Spanish, with the same person handling both languages, which matters if your buyers search in more than one.

You do not have to take our word for it. Run our free AI Visibility Checker to see where AI cites you today, and grade us by the same checklist we just handed you. If we fail a check, do not hire us. If we pass, let us prove it on your site.
