GEO consultant or GEO agency: who to hire so AI names your brand

When a company decides it wants to show up in ChatGPT, Perplexity, or Gemini answers, the first question isn't technical: it's who to call. There are independent GEO consultants, agencies that added GEO to their SEO service, and the option of training someone on your team. All three work, but not for the same company or at the same stage.

The short answer: a consultant is for diagnosing and handing you a plan; an agency is for executing that plan every month. The most expensive mistake is hiring the other way around — paying an agency to tell you what to do, or a consultant to write twenty articles.

Key takeaways

• +A GEO consultant pays off in the diagnosis: audit, baseline measurement across the models, and a prioritized plan. It's the cheapest way to find out where you stand.
• +A GEO agency pays off in ongoing execution: content, structured data, third-party mentions, and monthly measurement. It needs enough work volume to justify itself.
• +Doing it in-house works if you already have someone who writes and publishes regularly; GEO can be learned, consistency can't be improvised.
• +Working with a Latin American team, a consultant's audit runs USD 800–2,000 and an agency retainer starts around USD 500 a month.
• +The combination most small businesses use: a consultant or audit to start, in-house or agency execution after, and an outside review every quarter.

What a GEO consultant does

A GEO consultant is one person — sometimes with one or two collaborators — who reviews your site and brand from the point of view of generative engines and delivers a diagnosis. The typical work includes running a set of real questions from your industry through each model to see whether you appear and who gets cited instead, reviewing the technical foundation (crawling, speed, AI crawler access), auditing your structured data and the consistency of your brand as an entity, and leaving a 90-day plan ranked by impact.

What a consultant usually does not do is the heavy lifting: writing content month after month, earning mentions in media or directories, or implementing changes on your site. Some offer it by the hour, but then they lose their price advantage over an agency.

When a consultant makes sense

• +You don't know whether GEO is worth it for you and want a data-backed answer before committing to a monthly budget.
• +You have your own marketing team or a developer, and what's missing is the judgment to prioritize.
• +You already work with an SEO agency and want a second opinion on whether their work covers the AI side.

What a GEO agency does

An agency starts with the same diagnosis, but its value is in what comes next: executing every month. That means producing content written to be cited, keeping structured data current as the site changes, building the brand's presence in the sources the models draw on, and re-running the question set every month to show progress.

The upside is continuity and having several disciplines under one roof — writing, development, technical SEO. The downside is the fixed cost and the risk of paying for a generic plan if the agency doesn't understand your business. That's why it pays to ask the same questions you'd ask any GEO provider before signing.

When an agency makes sense

• +You sell something customers research before buying, and competitors already show up in AI answers.
• +Nobody in-house can publish content on a regular schedule.
• +You need someone to touch the site: schema, speed, new pages. A consultant tells you what to change; the agency changes it.

The third option: doing it in-house

GEO isn't a black box. A good part of the work — putting clear answers at the top of each page, keeping company details identical everywhere, asking ChatGPT the same questions once a month and logging the result — can be done by someone on your team with a guide. The hard part isn't the knowledge: it's sustaining it for six months without it slipping behind day-to-day emergencies.

If you have that person, the most efficient setup is usually paying for an outside audit to start with the right plan and keeping execution in-house. If you don't, hiring someone just for this rarely pencils out for a small business.

Quick comparison

• +Cost: consultant, USD 800–2,000 per one-off audit · agency, from USD 500 a month · in-house, team hours plus an initial outside audit.
• +What you get: consultant, diagnosis and plan · agency, diagnosis, execution, and monthly measurement · in-house, whatever the team can sustain.
• +Time to start: consultant, two to three weeks · agency, a month of setup · in-house, depends on the learning curve.
• +Main risk: consultant, the plan ends up in a drawer · agency, paying for months of generic work · in-house, it gets dropped by month three.

The useful question isn't «consultant or agency?» but «who's going to execute the plan every month?». If the answer is someone on your team, you need a consultant. If the answer is nobody, you need an agency.

What to get in writing, whoever you hire

• +The list of questions that will be measured across the models, and the baseline result before work starts.
• +Which concrete deliverables arrive each month — not «ongoing optimization».
• +What stays in your name if the engagement ends: content, schema, documentation, and access.
• +How a month with no movement will be explained, because there will be one.

At loco22 we work both ways: the audit on its own, for teams that prefer to execute in-house, or the audit plus a monthly retainer. If you're not sure which fits, tell us what you sell and who publishes content at your company today, and we'll tell you which one makes sense — even if the answer is that you don't need either yet.
