GEO consultant: choosing a provider to get visible in generative engines

You are a B2B marketing or SEO manager and you are considering outside help to get cited by ChatGPT, Perplexity, Gemini and Google's AI Overviews. This page helps you choose a GEO consultant, an agency or a platform to get visible in generative engines: what a provider must deliver, the questions to ask before you sign and how to judge their work over time.

Generative Engine Optimization (GEO) aims to make a brand visible and cited in the answers of generative engines. For the discipline itself, start with the complete guide to GEO.

When to bring in a GEO provider

In generative engines, visibility is not limited to ranking: the engine selects sources, summarises them and may name a brand without sending traffic to its website. A GEO provider makes this presence observable, then improves it without undermining your existing SEO foundations. GEO complements SEO; it does not replace it.

Outside support becomes a priority in a few typical B2B situations:

• A buying cycle built on reassurance: security, compliance, method and ROI weigh on the shortlist.
• Expert topics: definitions, sources and last-updated dates determine whether your content gets reused.
• Multiple domains or multiple languages: brand consistency gets lost from one site to the next.
• Fragmented production: marketing, product and PR each publish their own version of the offer.

What a GEO consultant does, mission by mission

A GEO consultant works on your site and on the ecosystem of sources that feeds generated answers: media, communities, reviews, third-party pages. Their objective is to increase the probability that your brand is named or your domain is cited. In B2B, accuracy matters as much as presence: a citation that distorts your offer hurts conversion.

The following table describes the six missions of a complete engagement and how to judge each one:

The scope: your site and the sources that talk about you

Part of the work happens on your pages, the rest on mentions, reviews and third-party pages. A provider who only talks about your site covers half the subject. To be cited, content must be:

• Indexed and accessible: open to AI crawlers (GPTBot, PerplexityBot, Google-Extended, ClaudeBot).
• Structured: hierarchical headings, lists, tables, direct answers, FAQs.
• Up to date and attributable: visible date, author, entity, sources.
• Consistent across the web: the same facts in mentions, reviews and third-party pages.

The deliverables to get in writing

A serious engagement produces documents your teams can reuse without the provider. By the end of the first month, you should have:

• A baseline: the question set and the initial snapshot of citations and mentions.
• A combined GEO & SEO audit: priority pages, entity confusion, pages to rewrite.
• A prioritised roadmap: impact, effort, dependencies and owners.
• Editorial rules: extractable structure, sources, dates, approval.

Measuring and iterating on a fixed cadence

Answers vary from one model to another and from one session to the next. The provider therefore measures on a fixed, repeated question set and records, for each question, whether the brand is named, the domain is cited, the domain appears as a source or it is absent. The value of an engagement shows in this repeated loop, not in a one-off audit.

Consultant, agency or platform: which model to choose

This is not about finding the "best supplier", but about choosing a governance model that fits your resources. A consultant frames and trains, an agency executes at volume, a platform equips your teams. The three can be combined: a consultant can steer the method while a platform carries measurement and production.

Here is what each model gives you and what it leaves with you:

Choosing based on your internal maturity

Four internal questions guide the choice more reliably than comparing offers:

• Your resources: who writes, who approves, who publishes?
• Your technical debt: template structure, page rendering, AI crawler access.
• Your approval constraints: legal, compliance, subject-matter experts.
• Your cadence: monthly, fortnightly or quarterly.

If your approvals are lengthy, favour a model that documents decisions and standardises formats. For multi-country set-ups, check the ability to maintain a question set per market and consistent entities from one language to another.

Who writes and who owns the content

Ownership comes up as soon as you receive the quote. Briefs, pages, the question set and the history of snapshots must belong to you at the end of the contract. Without this, changing provider means starting again with no "before", and so no way to judge what follows. Also ask what is done in-house and what is subcontracted.

The skills of a good GEO consultant

A good GEO consultant combines solid SEO foundations with skills specific to generative engines. They understand how an engine selects its sources, know how to structure a page so that a passage is extractable and can measure despite answer variability. Finally, they connect their recommendations to business outcomes: shortlist, leads, CAC.

The following table shows what to look for during the conversation and the risk if the skill is missing:

Certifications: what really matters

At the time of writing, there is no GEO certification recognised as a standard. An AI-related label does not prove operational capability. What matters is a written method, detailed deliverables and results presented as before / after on presence, citations or traffic from AI engines.

Teaching and coordination

In B2B, the problem is rarely knowing what to do; it is getting it approved and maintained. The consultant trains your teams, works with the internal experts who hold the evidence and coordinates content, technical and PR. The aim is shared habits, not dependency.

The questions to ask before you sign

A single scoping meeting is enough to tell a method from a pitch. Answers must be precise, written down and included in the proposal.

On method and measurement

Start with how the provider observes your presence:

• Which question set: how many questions, built for which personas, frozen at what point?
• Which engines: ChatGPT, Perplexity, Gemini, Copilot, Le Chat, AI Overviews and AI Mode?
• How do you measure: which states are recorded, how often, with how many repetitions?
• How do you read change: each page compared with itself, as correlation?

AI Overviews and AI Mode have been available in France since summer 2026. Search Console counts their impressions and clicks in the Performance report without separating them: a provider who claims to split them in that tool is mistaken.

On production and ownership

Then ask the provider how the work is made and what stays with you:

• Who writes: writers, experts, supervised generation, and who reviews?
• Who validates the facts: what approval route for product, legal and compliance?
• Who owns the content: briefs, pages, question set and snapshot history?
• Who works on authority: which third-party sources, chosen how?

On this last point, domain authority weighs in AI answers: mentions and links from sites that the engines cite count as much as your own pages.

Red flags

Some promises are enough to rule out a provider. Generative engines publish no ranking, and their answers vary from one session to the next: no serious offer can guarantee a result in a model it does not control.

Reject any proposal that shows one of these signals:

• A promised "position" in ChatGPT: the notion does not exist in a generated answer.
• Guaranteed results: assured citations, firm deadlines, announced percentage gains.
• No question set: without a fixed list, there is no before and no after.
• Unnamed tools: a measurement whose source stays secret cannot be checked.
• A city page: a "GEO" offer that talks about areas and maps confuses it with local search.
• A price before diagnosis: a price set without a presence audit rests on nothing.

Be wary too of "best consultants" or "best agencies" rankings: they reflect popularity or networks more than method. At best, use them to build a list, then put each name through the filter of deliverables and measurement.

Judging a provider at 3, 6 and 12 months

Action comes before measurement: a provider first produces citable content, then instruments its tracking. Judgement is therefore built in stages, each with its own evidence.

What to check at each milestone

The following table shows what to check at each milestone and the decision that follows:

Reading results without over-interpreting

Each page is compared with itself before / after publication, and the link between an action and a citation remains a correlation over time, never causation. A question that was not tracked before the engagement has no "before": it goes into the "no baseline" category. For traffic, Google Analytics 4 isolates sessions coming from chatgpt.com or perplexity.ai.

How much a GEO engagement costs

The median budget for an engagement that includes GEO is €5,000 excl. VAT (La Fabrique du Net, 2026). This benchmark does not replace a quote based on a written scope: number of pages, size of the question set, engines tracked and deliverables. To compare billing models and market ranges, see our page on choosing an SEO agency.

Depending on your situation

Depending on where you are, the next read is not the same:

• You are preparing a budget and an organisation: the page on GEO for business details roles, roadmap and ROI.
• You want to do part of the work in-house: follow the step-by-step GEO referencing method, then compare it with the proposal you received.
• You need to judge a provider already in place: use the indicators and attribution framework of the GEO KPIs.
• You have no baseline yet: start with a GEO audit of your presence in AI engines.

Before consulting providers, you can have your own baseline: the Incremys platform emulates your personas in AI engines, reads what they ask and who gets cited, and turns it into a unified brief; its 360° GEO & SEO audit records the AI presence of each keyword. To compare this model with a consultant or an agency, read our page GEO & SEO agency: what Incremys does instead.

FAQ about GEO consultants

What is a GEO consultant?

A GEO consultant is a specialist who helps a brand get named and cited in the answers of generative engines. They work on the site (structure, content, evidence) and on the third-party sources these engines reuse. They measure presence on a fixed question set, alongside SEO indicators.

How is a GEO consultant different from an SEO consultant?

An SEO consultant targets rankings in search results pages and the click; a GEO consultant targets presence inside a generated answer, sometimes without a click. The indicators differ: citations per question, AI share of voice, traffic from AI engines. GEO builds on SEO fundamentals; it does not replace them.

GEO consultant, agency or platform?

The right model depends on your internal resources. A consultant brings method, measurement and training to a team that produces its own content. An agency takes on execution when the team lacks capacity. A platform equips your teams so that they stay in control of data, content and cadence.

How do you judge a GEO provider?

You judge a GEO provider on their written method and on before / after results. Check that they freeze a question set per persona, measure each engine separately and end every report with decisions. At three months, look at the method; at six and twelve months, at how citations have changed.

How much does a GEO engagement cost?

The median budget for an engagement that includes GEO is €5,000 excl. VAT (La Fabrique du Net, 2026). The real cost depends on the number of pages, the size of the question set, the engines tracked and how much production is included. A serious quote follows a diagnosis and describes this scope in writing.

Can anyone guarantee a citation in ChatGPT?

No, nobody can guarantee a citation in ChatGPT or in any other generative engine. Answers vary from one model to another and from one session to the next, and no provider controls source selection. You can only make content more citable, then measure its presence before / after on a fixed question set.

Which deliverables should you require in the first month?

The first month must deliver a baseline: the question set and the initial snapshot of citations and mentions. Add to that a combined GEO & SEO audit of priority pages, a roadmap with its dependencies and reusable editorial rules. Without these documents, you will not be able to judge the rest of the engagement.
