How to Choose a GEO Agency: What to Check Before You Sign

What does a good GEO agency selection process look like?

Five steps: about three to six weeks to reach a preferred agency (steps 1–4), then a paid pilot of two to three months (step 5) before any long retainer:

1. Write down your own questions first: 15–30 buyer questions you want to be recommended for, the engines your buyers use, and your budget. Without this you will judge agencies on their pitch.
2. Build a longlist of five to eight agencies from referrals, practitioners whose published work you respect, and directories.
3. Send the same question set to each, covering definition, measurement, work, reporting and terms, and compare the written answers side by side.
4. Review evidence: sample reports, case studies and references for the two or three strongest.
5. Run a short paid pilot with your preferred agency, such as an audit and baseline on your own questions, before a long retainer.

How do you tell whether an agency is doing new work or relabelling SEO?

Much of good GEO overlaps with good SEO, and that is fine. The problem is an agency that changes the name but not the work. Signs of real GEO work:

• It measures AI answers directly, by engine and question, over repeated runs, not only rankings and traffic.
• It looks at what engines cite, and plans outreach and content around those sources.
• It checks accuracy, meaning what engines say about you, and fixes wrong facts at their source.
• It works off-site, on the lists, directories, reviews and publications engines rely on, not just your own pages.
• It checks access for AI crawlers, not only Googlebot.

Signs of relabelling: reports that are all rankings, traffic and backlinks with an "AI" section of screenshots; deliverables identical to the agency's SEO package; no answers from engines other than Google. A test for audits in particular is in what a GEO audit template should include.

What should you ask about the agency's definition and measurement of GEO?

Ask each agency to answer in writing:

• "How do you define GEO, and how is it different from what you do for SEO?"
• "What is the main metric you will report, and exactly how is it calculated?"
• "How do you separate being mentioned, being cited and being recommended?"
• "How do you handle the fact that answers change between runs?"
• "What would you consider a good result for us in six months, and how would we see it?"

Good answers are specific: "We report recommendation rate per question and engine, from five runs per question per month, with the raw answers linked." Weak answers stay general: "We improve your AI visibility score across all major platforms."

What should you ask about testing buyer questions across AI engines?

If an agency says it tracks your visibility across five engines, find out what that means:

1. Which engines and modes: ChatGPT with search, Google AI Overviews and AI Mode, Gemini, Perplexity, Claude, Copilot?
2. Whose questions: yours, from sales and support evidence, or a generated set?
3. How many runs per question per engine, and how often?
4. From which location and language, and in clean sessions?
5. Is it done through a tool, by hand, or both, and can you see every answer?
6. How are brand names detected, including your products and misspellings?

An agency that tests a handful of generic prompts once a month in one engine is not measuring what it claims.

How do you evaluate an agency by citations, explanations and cross-engine measurement?

Three things separate strong agencies:

• Citations: they can show which pages engines cite for your questions, which of those mention you, and a plan for the rest.
• Explanations: for each question where you lose, they can explain why, using the cited sources and answers, not general theory.
• Cross-engine measurement: they report each engine separately, because engines cite different sources and a single average hides where you are missing.

Ask them to demonstrate on one of your questions during the pitch. A capable agency can run it, read the sources and give a credible explanation in under an hour.

How do you evaluate an agency's results, methods, tools and case studies?

A trustworthy GEO case study includes:

Be wary of case studies built on single screenshots of ChatGPT naming the client, percentages without sample sizes, or proprietary scores. On tools, ask which ones the agency uses and whether you get direct access to the underlying data; if you leave, you should keep it.

Should one agency handle both traditional SEO and AI search?

Often yes, because the work overlaps: crawlability, clear pages that answer questions, and strong third-party presence help both. An integrated agency avoids two teams changing the same pages with different goals. Check three things:

• that the AI search work has its own measurement and deliverables, not just an extra line in the SEO report;
• that someone on the team owns AI visibility, with time allocated to it;
• that off-site work, such as lists, reviews and publications, is included, since it is often more important for AI answers than for rankings.

If your existing SEO agency is strong but new to GEO, a separate GEO specialist for audit and strategy, working with the SEO agency on delivery, can be a good middle path. See also whether to do GEO yourself, hire a freelancer or hire an agency.

How do you find and shortlist GEO agencies in the US?

There is no reliable ranking of GEO agencies yet: published "best GEO agency" lists are mostly self-published or sponsored, as how to compare AI visibility agencies explains. Build your shortlist from:

• referrals from peers in your industry who have seen results;
• practitioners' published work: agencies that publish their methods, data and failures, not just service pages;
• agency directories and reviews, read for detail rather than star ratings;
• industry fit: regulated fields such as healthcare, finance and legal need an agency that knows the advertising and privacy rules that apply, such as FINRA's rules on communications for broker-dealers or HIPAA for health information;
• practical fit: time zone, team size and whether the people who pitch will do the work.

Ask each shortlisted agency for two references from clients with similar size and industry, and speak to them.

What contract terms should you look for?

Beyond price, check that the contract covers a baseline before work starts, named monthly deliverables, access to all data and answers, ownership of content and accounts, and a short initial term or a clear exit. Pricing ranges and more before-signing questions are in what GEO and AEO agencies charge per month.

What do people ask about choosing a GEO agency?

How long should a GEO agency trial last?

Two to three months is usually enough to see whether the work is being done and whether leading signals, such as citations and corrected facts, move. Recommendation rates can take longer.

Should a GEO agency guarantee results?

No. Nobody controls what AI engines say. Be cautious of guarantees; ask instead for committed deliverables and transparent measurement.

Is a GEO specialist better than a large SEO agency?

It depends on the team. Some specialists are excellent; some large agencies have strong GEO teams. Judge by evidence and the people who will do the work.

What is the biggest red flag in a GEO pitch?

A proprietary score with no way to see the answers behind it. If you cannot check the measurement, you cannot tell whether the work is working.
