To choose a Generative Engine Optimization (GEO) agency in 2026, look for one that can measure how AI engines describe you, applies a real GEO method rather than the SEO playbook with a new label, and runs content, structured data, digital PR, and reputation as one program. The decisive test is simple: can they show you how AI engines currently describe your brand, and track how that changes over time?
GEO is new enough that most buyers cannot yet tell a real specialist from an SEO agency that added the word GEO to its homepage. The category is filling with both, and the language they use sounds almost identical. This guide gives you a practical way to tell them apart: what actually matters, the warning signs, and the questions that reveal whether an agency can really influence how AI engines answer questions about you.
First, what a GEO agency is actually for
More and more people research brands by asking an AI assistant a question and reading a single synthesised answer, rather than scanning a page of links. Generative Engine Optimization (GEO) is the work of making sure that when engines like ChatGPT, Gemini, Claude, Perplexity, and Copilot answer questions in your category, your brand is part of the answer, described accurately and favourably. That is a different goal from traditional SEO, which is about ranking your own pages. The two overlap, but a GEO agency is judged on whether you get cited inside the answer, not on where a page sits in a list.
The criteria that actually matter
Score any agency you are considering against these seven. A genuine GEO specialist clears all of them; an SEO agency with a GEO page tends to stumble on the first two.
1. It measures AI citations, not just rankings. This is the dividing line. A real GEO agency tracks how often and how accurately AI engines mention you across a defined set of queries and several engines, using measures like citation frequency, share of voice, and sentiment. If the only numbers on offer are Google rankings and traffic, you are looking at SEO.
2. It can show your current AI visibility. The strongest signal of real capability is concrete evidence. A capable agency can show you, in a clear report, how the major engines describe your brand right now: where you are cited, where you are absent, and how those mentions change over time. Current, measured evidence beats a theoretical pitch.
3. A real GEO method, not the SEO playbook with a new label. GEO overlaps with SEO but works differently, built on entity clarity, passage-level content, structured data, citation ecosystems, and the PR and reputation signals that earn citations. Ask how their GEO process actually differs from standard SEO. “The same playbook, plus some schema” is not really GEO.
4. It runs content, structured data, digital PR, and reputation as one program. AI engines cite sources they trust, and trust is built from several signals at once: authoritative third-party coverage, clean structured data, clear entity definitions, and positive sentiment. An agency that does only one of these will underperform. The integrated, GEO-first approach is what compounds.
5. It builds authority and entity signals, not just on-page schema. Adding FAQ markup to your site is a small part of the job. The harder, higher-impact work is earning the independent coverage and entity signals, through digital PR, that make engines confident enough to cite you. Schema without authority rarely moves citations.
6. It is reputation-aware. AI answers synthesise sentiment, so a GEO program that ignores reputation can end up amplifying the wrong narrative. This matters most in regulated or sensitive sectors such as finance, health, and legal, where how you are described carries real consequences.
7. It gives you a baseline and transparent, query-level reporting. A serious agency shows you where you stand before the work starts, through an AI-visibility audit, then reports citation movement at the query level each month, across engines and, if you operate internationally, across your key languages. It commits to realistic timelines, not guaranteed AI rankings.
How to tell a real GEO agency from an SEO agency with a GEO page
If you only remember one thing from this guide, make it the table below. It is the fastest way to read which kind of agency you are talking to.
| What to compare | A real GEO agency | An SEO agency with a GEO page |
| Primary metric | AI citation frequency, share of voice, and sentiment | Google rankings and clicks |
| What they look at | How AI engines currently describe you, across engines and queries | Where your pages rank in Google |
| Core method | Entity clarity, passage-level content, citation ecosystems, digital PR, reputation | Keywords, backlinks, and on-page tweaks |
| What you receive | Reports on your AI citations and how they change over time | Rank and traffic reports |
| What they promise | Measurable influence over time | Guaranteed rankings or AI placements |
Red flags to walk away from
Some signals are reliable enough to end the conversation on their own:
- Guaranteed AI rankings or citations. No one controls what AI engines say. A promise to make you the top answer in ChatGPT or to guarantee a citation usually means either overpromising or methods that will not hold up.
- GEO that means “we will add some FAQ schema.” Schema helps, but on its own it is not GEO. If there is no citation measurement behind it, it is window dressing.
- Only Google-rank metrics. If an agency cannot describe how it measures AI citations, it is not really doing GEO, whatever the homepage says.
- No baseline. If they cannot show your current AI visibility before you start, they cannot prove any progress later.
- Vague about engines and queries. A real program names the engines and the specific queries it will track for you. Hand-waving here is a tell.
- Ignores reputation and sentiment. An agency that treats GEO as purely technical will miss the sentiment signals that shape how AI describes you.
- Magic claims about training the models. Be wary of anyone who says they can directly train or hard-code the major AI engines to favour you. The real work is influencing the sources and signals those engines draw on.
Questions to ask on a discovery call
Bring these to any agency you are evaluating. The quality of the answers tells you most of what you need to know:
- How do you measure AI visibility, and which metrics do you report (citation frequency, share of voice, sentiment)?
- Can you show me a report of how the major engines currently describe our brand and where we are cited?
- How does your GEO process actually differ from standard SEO?
- How do you combine content, structured data, digital PR, and reputation in one program?
- Which AI engines and which specific queries will you track for us, and how often will you report?
- What will you show me about our current AI visibility before we start?
- What realistic timeline and outcomes have you delivered, and what do you change when citations stall?
- How do you handle our sector’s sensitivities and the languages or markets we operate in?
A simple way to read the answers: only Google-rank metrics, a guarantee of AI rankings, or an inability to show how the engines currently describe you are each enough to stop. An agency that measures citations, reports them honestly over time, and runs content, data, PR, and reputation together belongs on your shortlist.
How Buzz Dealer measures up
We will not claim to be right for every brand, because that is the kind of blanket promise this guide warns against. Here is how Buzz Dealer maps to the criteria above, so you can judge for yourself.
We built GEO as a distinct discipline on top of 15+ years of SEO and online reputation work, now evolved for the AI era through our GEO-first framework. Every engagement starts with an AI visibility and presence audit: we test how engines like ChatGPT, Gemini, Claude, Perplexity, and Copilot currently describe you, then map which sources and entities those models already trust. From there we work to earn accurate citations, and we report progress through citation frequency, share of voice, and sentiment rather than rankings alone.
Because we run content, structured data, digital PR, reputation, and SEO under one roof, improving your GEO strengthens the other channels at the same time, which is the whole point of a GEO-first program. We work across multiple languages and markets, and we treat reputation as part of the job rather than an afterthought, which matters in the regulated and sensitive sectors we know well. What we will not do is promise to control what the engines say, because no one can. We measure it, we move it, and we show you the evidence.
If you want to see where you stand, the most useful first step is an AI visibility audit of how the major engines currently describe your brand, and where the highest-impact gaps are.
