Best GEO proof from AI optimization agencies: 7 questions
4 September 2026 · · 6 min read
The best AI optimization agency is one that measures your visibility upfront, openly shares what it finds in which AI systems, and proves its own approach with measurable results, not reports. Ask these 7 questions about measurement, proof, and execution before you sign a contract. An agency that doesn't measure sells a promise; an agency that measures sells a program.
You've seen the reports and heard the presentations. Every agency promises your IT company will rank at the top in ChatGPT, Gemini, Claude, and Perplexity. Yet the same names keep coming up, while the real results often stay vague.
The question isn't which agency has the nicest website. The question is which agency can demonstrate and grow your visibility. For that, you don't need marketing talk, but a concrete checklist.
Without measurement, GEO is a promise; with measurement, it's a program your management can follow. An agency that says it improves your visibility must first be able to show where you stand now. Only then can you assess after a few months whether the effort works.
One-off scans say little. So always ask for a baseline measurement you can verify yourself. A good baseline looks at multiple AI assistants, not just the most popular one. That gives you a picture of the full market.
Also ask how often the agency measures. Weekly or monthly reporting is better than a single snapshot at the start. You want a trend, not a photo.
The easiest way to test an agency is to ask for proof. Where does the agency itself stand in AI answers? An agency claiming to be an expert must be visible in its own market. An agency that can't be found itself can't do that for you either.
Ask for a free scan of your current AI visibility. A reliable agency offers this without requiring you to leave an email address. That way you can assess the quality of their analysis before you engage in a conversation. The scan should provide insight into where you stand in the four major AI assistants.
Pay attention to the sources an agency uses. Good agencies base their analyses on data from tools like Similarweb or specialized reports. Ask which sources they consult. An agency that can't name sources is probably working with assumptions.
Many agencies deliver a list of recommendations. You then have to execute them yourself. With technical optimization, that's a problem, because the chance it gets shelved is high. Choose an agency that performs the technical optimization on your site itself.
An agency that thinks along the entire chain is more valuable. Think of generating reviews, sending press releases, and building citations in trade media. These are pieces AI assistants use to determine who they recommend.
So ask explicitly about execution. Who implements the technical changes? Who arranges the publications? And who is responsible for the result of those efforts? A clear answer prevents disappointment later.
AI assistants rely on context. One of the most important contexts is what your customers say about you. A small number of authentic reviews is therefore essential. Ask how the agency approaches this.
An agency that calls your customers and drafts the review text for them makes it easy for your customers. They only need to approve and post the text. That gets you quality reviews without costing your customers much time.
Keep in mind that a few solid reviews are worth more than hundreds of generic mentions. The names and roles of your customers matter. A CEO saying something about your collaboration weighs more than an anonymous user.
AI assistants don't read websites alone. They pull information from comparison articles, news reports, and trade media. If your company isn't mentioned there, you miss a large part of the sources AI assistants use.
Ask whether the agency writes and sends press releases. A good agency has contacts at national media and knows which journalistic channels have influence. The goal is that your brand appears in the stories assistants read along.
Also pay attention to focus. A press release about a new client is good, but a substantive story about a trend in your sector is better. That gets picked up and cited by other media more often.
Industry knowledge is important, but knowledge of what goes wrong is at least as valuable. An agency that knows the pitfalls can avoid them for you. So ask about the most common mistakes in GEO trajectories.
A common mistake is copying content from competitors. AI systems recognize that and penalize it. Another mistake is ignoring the technical foundation. Without a correctly indexed site, content has no effect.
Also ask whether the agency is honest about what it can't do. Guaranteed positions in AI answers don't exist, at any agency. An agency that does give that guarantee is selling nonsense. Trust an agency that focuses on measurably improving the chance you get mentioned.
The cost of AI optimization can vary widely. So always ask for a clear price quote. What's included in the base rate and what are the optional costs? An agency that's vague about this probably has something to hide.
Check whether the price reflects the work. An agency that does a lot for little money probably delivers shallow work. An agency that's expensive but delivers no proof isn't a good choice either. Look for a middle ground with transparent terms.
Also ask whether you can purchase separate components. Maybe you first want only a baseline measurement, or only the technical optimization. A flexible agency that thinks along here is often more reliable than one that only sells full packages.
GEO isn't a one-off project. It's an ongoing effort you need to keep tracking. So ask how the agency sees its own role. Is it a vendor executing an assignment, or a partner thinking along about the long term?
An agency that fits well understands your target audience. For an IT company that's different than for a consumer brand. The message and channels must align with how your customers make decisions.
Finally, check whether the agency is in your network. An agency that can deploy CEOs and specialists from its own network has an advantage. Those people can serve as sources for citations and contributions that AI assistants notice.
With this checklist, you can compare agencies objectively. Ask for proof, measurement methods, and execution. Don't trust promises, but what the agency can show. A good agency starts with an honest baseline measurement and builds a program on it that your management can follow.
This approach helps you choose not the first or most expensive agency, but the one that best fits your situation. The investment you make must deliver measurable returns. With the right questions, that becomes clear.
The best way is to ask for measurable proof. An agency should be able to deliver a free scan of your AI visibility, where you don't leave an email address to assess the quality of their analysis. Also ask which sources they use and how they handle the execution of technical optimization.
No, guaranteed positions in AI answers don't exist, at any agency. AI systems are too dynamic and user behavior changes continuously. A reliable agency focuses on measurably improving the chance your brand gets mentioned, instead of giving an impossible guarantee.
A baseline measurement is the only way to prove later that the work had an effect. Without a starting point, you can't measure progress. A good baseline looks at multiple AI assistants, not just the most popular one, and gives a picture of the full market. That way you can objectively assess after a few months whether the investment works.
