GEO Agency Comparison: Which Type Fits Your Business

Type "best GEO agency" into a search box and most of what comes back is not written by agencies at all. Sponsored articles on news portals, agency directory sites, "top 10 agencies of the year" round-ups and personal blogs fill the results. That is not an accident: the intent behind the query is not to find one brand, it is to see a list of options. AI assistants answering the same question mostly read and summarise those same round-ups.

There is a problem with that arrangement. The ranking inside those lists is built on the list author's criteria, not on what your business needs — and that criterion is usually never written down anywhere. This article does not add another list. The aim is to give you a framework you can use to work out not which agency is "best", but which kind of supplier fits your situation.

What do "best agency" lists actually measure?

Open any round-up and look for two things: is the ranking criterion written down, and is that criterion measurable. Most lists have neither. In their place you get unverifiable phrases — "creative team", "client-focused approach", "years of experience in the sector". Some do not explain how the order was arrived at all, and simply stack names and short blurbs one under the other.

There is exactly one situation where a list like that is useful: finding out who exists in the market. It is good for producing a long pool of candidates. But choosing from the pool is your job, not the list's. You have to derive the selection criteria from your own needs; we broke those criteria down in detail in our guide to choosing a GEO agency. Here we take a step back and ask something earlier: what kind of supplier is sitting across the table from you?

Four types of supplier in the market

Four different business models are behind the sentence "we do GEO". None of them is inherently better than the others; they differ in where they sit on the triangle of scope, depth and price.

The full-service digital agency. Ad management, social media, web design, content and SEO under one roof. Telltale signs: a service menu longer than eight items, GEO appearing not as its own service page but as a paragraph inside the SEO page, and no named person on the team page dedicated to this work. It makes sense for businesses that need a single point of contact and run several channels at once. The risk is that GEO ends up being the line item that gets the least time inside the package.

The agency with SEO roots. A team that has done organic search for years and has added GEO on top of the existing service. Telltale signs: case studies built on organic traffic charts, proposals phrased as "this many keywords", and a rank-tracking tool named as the measurement instrument. The technical groundwork is usually solid; the divergence starts on the measurement side, because in generative answers there is no rank number to track. You can gauge where your current agency sits on this line using the questions in our piece on whether your SEO agency is doing GEO.

The GEO-focused boutique. Narrow service menu, small team, founder involved in the work. Telltale signs: its own site passes the checks it sells — llms.txt, schema markup, server-side rendering; it uses concepts like prompt sets and engine coverage openly in its own content. Transparency is comparatively easy to verify, because its own site is the shop window. The risk is scale: the number of engagements it can run at once is limited, and it usually does not cover items like advertising or social media. For transparency: Next GEO Agency belongs to this third category, and the scale risk described here applies to us too.

The measurement software vendor. Not really an agency — it sells a tool. Telltale signs: a pricing page on the site and a monthly user or query limit; what is sold is access, not service. Implementation stays with you: the software tells you which questions you are missing from, and who produces the content and technical fixes that close that gap is a separate question. If you have a team inside who can implement, this is the cheapest route; if you do not, you have bought only the diagnostic half of the job.

A fifth option, the independent consultant, behaves in practice like a one-person version of the third type: the verification method is the same, the only difference is that there is no backup.

A table that puts the types side by side

The table below compares types, not brand names. Mark the cells closest to your own situation and see which column collects the most marks.

No single row decides anything on its own. What it does show is why evaluating proposals from two different types on the same scale is wrong: comparing a software subscription with an agency retainer on price alone means leaving half of what you are buying out of the calculation.

Ten questions to ask in the meeting

These questions are not an exam. Each one exists to make visible which type you are dealing with and where the scope stops. Take notes on the answers in the meeting, then put the answers from two proposals side by side.

The tenth question was deliberately put last. A supplier who can describe what did not hold in their own work is measuring; a party that does not measure does not know what failed either.

Six pieces of evidence to ask for

Even when the spoken answers are good, the decision should rest on documents. There are six things it is reasonable to ask for at the proposal stage, and none of them is a trade secret.

• An anonymised sample report. Not a screenshot of a chart — the whole report. It should contain the measurement method, the question list and the date.
• A sample of the prompt set. How many questions it holds, which categories it is split into, how often it is updated.
• Engine coverage and measurement frequency. Which assistants, how many times a month, with how many repeats.
• The form raw data access takes. A dashboard, a spreadsheet file, on request. Holding that access yourself is the precondition for every comparison you make later.
• The team assignment. The names of the people who will do the work and the time allocated. It is normal for the person in the sales meeting to differ from the person doing the work; never being told so is not.
• The exit clause. How data, files and account access transfer when the contract ends.

Once these six documents arrive, comparing proposals stops being a matter of feel. If they do not arrive, note the stated reason as well: the reason is itself a data point.

Making proposals comparable

Two proposals rarely describe the same job. One covers content production, the other offers only technical fixes; one measures monthly, the other quarterly. Putting two numbers from that state side by side is misleading.

The practical way to fix the comparison is to reduce every proposal to your own line items: technical setup, content production, measurement and reporting, access-layer auditing, and reputation and off-site work. For each proposal, write "yes / partly / no" next to those five items. Then ask how many hours a month each item takes. Make price the last line you look at; we broke down which items the cost is made of in our guide to GEO cost line items.

A missing item is not bad on its own; it is enough to know who will do it. Keeping part of the decision in-house is a valid option too; our in-house versus agency decision matrix builds that split across five variables. On the advertising side, our article on ad agency fee models and account ownership runs the same comparison through the fee model and who owns the account.

Five sentences that count as a warning sign

The phrases below are not evidence of bad faith on their own. But if more than two of them appear in one proposal, asking for a written explanation before signing is reasonable.

"We will get you to the top spot in ChatGPT." There is no fixed notion of rank in generative answers; ask the same question twice and the answer can change. A rank guarantee is a commitment about something that cannot be measured.

Percentages with no source. If a claimed increase does not say which question set, which engine and which date range it was measured on, that number is an assertion, not a finding.

Not sharing the measurement method. A result presented without its method cannot be verified. "Our own methodology" is not a sufficient reason to hide how many questions were checked how many times to arrive at the result.

Client names used without permission. Brands cited as references whose names are used without those brands' approval. It means your name could be used the same way tomorrow.

Urgency with no scope behind it. The discount ending today, the slots about to fill. Any decision accelerated on price before scope and measurement are settled gets reopened in month three.

How to make the decision cheaper: a short pilot

You do not have to start with a one-year commitment. A narrow start with a defined end tests both the supplier and the way you work together. A pilot that works has four components: a baseline measurement over a fixed list of 20 to 40 questions, an audit of the access layer, a concrete fix on two to four pages, and a repeat measurement in week four using the same question list.

What you should expect at the end of a pilot is not results but the capacity to produce evidence: that the same questions could be measured twice, that the work done can be itemised by date and page, that the raw data was handed to you. If those arrive, you can sign the long contract comfortably; if they do not, your loss is one month.

In short, the ranking is your criteria's job, not a list writer's: diagnose the type, ask the ten questions, request the six documents, reduce proposals to the same five items, and start with a short pilot where you can.

Frequently Asked Questions

Can you trust "best GEO agency" lists?

Those lists are useful for building a candidate pool and useless for making the choice. Most do not state which criterion the ranking was built on, and some of them are sponsored content. The right way to use a list is to treat the names in it as a starting set and to do the elimination with your own criteria: diagnosing the supplier type, the measurement method, raw data access, and the exit clause in the contract.

What is the most decisive difference between the types of GEO agency?

Who does the implementation. Full-service agencies, SEO-rooted agencies and GEO-focused boutiques take the implementation on; a measurement software vendor only detects the gap and leaves the fixing to you. The second decisive difference is the expert time given to GEO: in an agency with a wide menu this work tends to be a small slice of the package, whereas in a narrow-scope team it is the whole job.

Which documents is it reasonable to ask for when choosing an agency?

An anonymised sample report, a sample of the question list being tracked, engine coverage and measurement frequency, how you will get to the raw data, the names of the people doing the work along with the time allocated, and an exit clause describing how data and access transfer when the contract ends. None of these is a trade secret; if they are not shared, ask for the reason in writing.

Should I rule out a proposal that guarantees rankings?

Before ruling it out, ask in writing exactly what is being guaranteed. Because generative search answers have no fixed rank, and because the answer can change when the same question is asked again, a "number one spot" commitment has no technical equivalent. If the other side can convert it into a measurable deliverable the conversation can continue; if they cannot, what is on the table is an unmeasurable promise.

I am a small business — which type should I start with?

If the budget is tight and there is someone in-house who can implement, starting with measurement software is the cheapest route; the software shows the gap and you close it. If there is nobody in-house, a narrow-scope start is safer: a concrete fix on a handful of pages and measurement against a fixed question list. In either case, starting with a short pilot rather than a long commitment brings the cost of the decision down to one month.
