GEO Agency: what it actually delivers and how to hold it accountable for results
A GEO (Generative Engine Optimization) agency works to get a company cited in the answers produced by AI systems such as ChatGPT, Gemini, Claude, Perplexity and Google's AI Overviews. The service combines search intent mapping, content structured for citation, structured data, off-site authority and AI mention monitoring. GEO does not replace SEO: it builds on it.
The market realized GEO sells, and a good share of SEO agencies simply swapped the sign on the door. Same deliverables, new proposal, a 2026 acronym on the cover.
If you are reviewing proposals right now, this guide shows what a serious GEO operation delivers every month and which warning signs should kill a proposal before you sign it.
What a GEO agency is
A GEO (Generative Engine Optimization) agency works to get your company cited in the answers produced by AI systems such as ChatGPT, Gemini, Claude, Perplexity, Copilot and Google's AI Overviews and AI Mode. The scope includes mapping the intents these AI systems answer about your market, producing citable content, structuring data and entity, building off-site authority and measuring AI share of voice by intent.
In practice, GEO work starts with a simple question: when someone asks an AI for a recommendation in your segment, who shows up in the answer?
If the answer does not include your brand, there is technical and editorial work to be done. And that work has a name, a method and measurable deliverables.
What changes compared to a traditional SEO agency
An SEO agency optimizes for ranking: position, click, traffic. A GEO agency optimizes for the citation: showing up inside the answer the AI assembles, even when there is no click at all.
The detail many proposals hide: GEO builds on SEO. AI systems query search indexes, read crawlable pages and prioritize sources with authority. A technically weak site does not become a cited source, no matter how good the content is.
The deliverables that define the service
A serious GEO scope includes, at minimum:
- AI mention audit: how each model describes your brand today, and where it does not show up at all.
- Intent mapping: the real questions buyers ask AI systems about your market.
- Direct-answer content: pages that answer in a format models can extract and cite.
- Structured data and entity: schema, consistency of name, address and description across every source.
- Off-site authority: press, mentions and references models use as proof.
- AI share of voice report by intent, with a defined collection frequency, alongside traffic coming from LLMs.
If the proposal covers only one or two of these points, it is a different service with a new label.
Signs your company needs GEO now
The problem rarely shows up under that name. It arrives disguised as a strange report, and most marketing teams take months to connect the dots.
Run the test against these four symptoms:
- Stable impressions, falling clicks in Search Console. Your page still shows up, but the user reads the AI-generated answer at the top and does not click. If that gap widened over the past few months, part of your funnel is already being answered before your site.
- The competitor is cited in ChatGPT and you are not. Ask the AI systems what a buyer would ask: "best supplier of X for a mid-sized company", "how to choose Y". If another brand is named and yours does not exist in the answer, you lost the comparison before you even entered it.
- Referral traffic from chat.openai.com and perplexity.ai in GA4 with nobody watching. That traffic already reaches your site, usually with high intent, because the person clicked after reading an answer. If nobody segments that source, you are deciding budget without seeing an entire channel.
- The AI describes your company incorrectly. Outdated positioning, a service you no longer offer, headquarters in the wrong city. Each of those answers is an uninformed salesperson talking to your prospect at scale.
Any one of these signs on its own deserves attention. Two or more together mean the purchase decision in your market started happening somewhere your brand has no measured presence, and revenue that disappears without leaving a trace in the funnel usually comes from exactly there.
How much a GEO agency costs and what is inside the price
Investment ranges in the Brazilian market
As an industry reference, GEO projects in Brazil usually run between R$ 4,000 and R$ 15,000 per month when integrated into an SEO contract. Enterprise scopes, with multiple brands or languages, go beyond that. The pricing logic is similar to what we detail in how much an SEO agency costs: the price follows the scope, not the name of the service.
Be wary of GEO sold as a cheap standalone item. If the proposal fits in R$ 1,500 per month, it is probably just a monitoring tool with an agency logo on it.
What drives the cost up: entity, content and off-site authority
Three fronts push the investment higher. First, entity work: structured data, brand consistency and presence in the sources AI systems query. Second, producing citable content, which demands technical depth and expert review, not volume. Third, off-site authority: press, mentions and link building, which is where most budgets get squeezed first and should not.
The more competitive the market, the heavier the third front weighs. In a B2B niche with few strong players, content solves it faster.
Billing models and what to avoid in the contract
A monthly fee with a defined scope is the healthy standard. Avoid three things: a contract promising a ChatGPT citation in 30 days, billing based on "AI position" (the metric is not stable enough for that yet) and a report that only shows Google traffic. If the monthly deliverable does not include AI share of voice by intent, the GEO in that proposal is decorative.
How to choose the right GEO agency
The commercial proposal reveals almost everything. Those who actually execute answer hard questions without dodging. Those who just swapped the SEO sign for GEO stall on the second question.
Questions that separate doers from talkers
Take these five into the meeting:
- Which AI systems do you monitor and how often? Expect names: ChatGPT, Gemini, Claude, Perplexity, AI Overviews and AI Mode.
- How is a citation measured? Ask to see the tool's screen, not a slide.
- What is the relationship between GEO and SEO in the contract? GEO builds on SEO. Anyone promising one without the other has not understood how AI systems choose sources.
- What lands on my desk every month? Published content, earned mentions, structured data implemented. Deliverables, not plans.
- Can you show me a citation obtained for another client? Those who have it show it on the spot.
How the agency should measure and report
Demand three metrics in the report: AI share of voice by intent (in how many answers about your market you appear), a list of citations with screenshot and date, and LLM traffic segmented in GA4. A live dashboard, available 24 hours a day, with a formal execution guarantee in the contract. The methodology Netlinks applies in GEO projects follows that logic.
Red flags in the proposal
Be wary of promises to show up in ChatGPT in 30 days, of a tool presented with no method behind it and of a report that only shows traffic. Traffic is a consequence. Citation by intent is what you are hiring.
Where to start this week
That report with stable impressions and falling clicks now has a name. Part of your buyer already decides by reading the AI's answer, and the question is no longer whether this affects your funnel. The question is who gets cited when ChatGPT or AI Mode talk about your market.
If you take three things away from this guide, make them these:
- GEO builds on SEO. A fast site, content that answers and authority outside your domain feed both Google and the AI systems. Anyone selling GEO in isolation is selling half the job.
- Citations are measured, not promised. Require named monitoring (which AI systems, how often) and share of voice by intent in the monthly report.
- The proposal exposes the agency. A promise to show up in ChatGPT in 30 days, a tool without a method and a traffic-only report are reasons to walk away from the table.
The practical step for tomorrow: take the 10 questions your buyer would ask an AI, run them in ChatGPT, Gemini and Perplexity and write down who gets cited. That survey becomes your yardstick for assessing any proposal.
At Netlinks, GEO runs inside SEO and GEO 360, with citation monitoring across dozens of AI systems through the Netlinks App and the same SEO agency discipline we have applied since 2017 across more than 200 companies.
Those who build real authority show up on both screens, in search and in the generated answer. Want to know where your brand stands on that map today? Talk to an Expert and get a diagnosis of your case, with no strings attached.
Frequently asked questions
What does a GEO agency do?
It works to get your company cited in the answers produced by AI systems such as ChatGPT, Gemini, Claude, Perplexity and Google's AI Overviews and AI Mode. The scope includes mapping the intents these AI systems answer about your market, producing direct and citable content, structuring data and entity, building off-site authority and reporting AI share of voice by intent, with citation evidence.
What is the difference between GEO and SEO?
SEO positions pages in traditional search. GEO works to get the brand cited inside AI-generated answers. The two disciplines support each other: AI systems draw from the same index, the same authority and the same content SEO builds. In practice, GEO without an SEO foundation has no raw material. That is why the best contracts treat both as a single front.
How much does a GEO agency cost in Brazil?
As an industry reference, GEO projects integrated into an SEO contract usually run between R$ 4,000 and R$ 15,000 per month. Enterprise scopes, with multiple brands, countries or languages, go beyond that. What defines the price is the scope: how many AI systems are monitored, volume of content produced, off-site authority work and depth of the monthly report.
How long does it take to show up in ChatGPT?
It depends on the authority the brand already has. Companies with a solid SEO base and external mentions can see citations within a few months. Brands starting from zero take longer. Be wary of anyone promising ChatGPT presence in 30 days: nobody controls what the models cite, what exists is a method to increase the probability of citation, intent by intent.
How do I know if my company already appears in AI answers?
Ask the questions your buyer would ask in ChatGPT, Gemini and Perplexity and see who gets cited. For scale, you need recurring monitoring: answers vary by day, by how the question is phrased and by model. An indirect signal in Search Console: stable impressions with falling clicks suggests the user is reading the AI answer and not clicking.
Does GEO replace SEO?
No. GEO depends on SEO to work. AI systems more frequently cite brands that already have indexable content, structured data, domain authority and press mentions, exactly what good SEO work delivers. Anyone selling GEO as a replacement is selling the same thing with a new sign, or selling something without a foundation.
What should a GEO agency deliver every month?
At minimum: an AI share of voice report by mapped intent, with screenshots or records of the citations obtained, a list of the AI systems monitored and the checking frequency, content published in the period, external authority actions (mentions, press, links) and prioritized next steps. A report that only shows Google traffic is an SEO report under another name.
