How to choose a GEO agency for the Mexican and US Hispanic market

Choosing a GEO agency comes down to one question: can they get an AI engine to cite your brand, and can they prove it with evidence? Most agencies still sell Google rankings and paint an "AI" label on top. A good GEO agency measures something different — how often ChatGPT, Perplexity, Gemini, or Claude name your business when someone asks about your category — and it shows you the screenshots. These are the seven criteria that separate one from the other.

If you operate in Mexico or sell to the U.S. Hispanic market, there is an eighth criterion almost no one meets. We saved it for last because it is usually the one that decides the call.

Do they measure citations or just rankings?

This is the question that orders all the others. SEO measures where you land in a list of links. GEO measures whether a generative engine mentions you inside the answer it gives the user, and whether it cites you as the source. Those are two different outcomes: you can rank first on Google and not exist for ChatGPT.

Ask the agency to state its primary metric in one sentence. If the answer is about "keywords" and "positions" with no mention of citations inside AI engines, they are selling SEO with a new name.

Will they show you which engines cite you today?

Nobody can improve what they have not measured. A serious agency starts with an audit: it asks all four engines a fixed set of questions from your category and records where you are mentioned, where you are cited with a link, and who gets named in your place.

If they hand you a content plan before showing you that snapshot of where you stand, they are guessing. The audit is not an add-on; it is the starting line.

Do they write to be cited, or only to rank?

Citable content has a recognizable shape. It opens by answering the question directly in the first few sentences — that is the block a model lifts verbatim — uses question-shaped headings, includes criteria lists, and backs every non-obvious claim with a linked source.

Ask to see an article they have written. Check three things:

• Does the first line answer the question, or take a historical detour?
• Are the headings questions real people actually type?
• Do the statistics link to their source, or float unsupported?

Do they handle the technical layer: schema, structured data, and llms.txt?

GEO is not just writing. Engines rely on signals you cannot see: structured data in JSON-LD, an llms.txt file at the root of the domain, entity consistency, and fast, clean pages. An agency that only delivers copy, without touching the technical layer, leaves you halfway there.

You do not need to understand the detail. You need to confirm that someone on their side does, and implements it.

Do they produce native bilingual content, or translated content?

This is where most of them fall down. Translating an article from English to Spanish is not bilingual content — it is content in one language with a second-hand copy in the other. A native reader notices in the first line, and a generative engine also treats translated material as a derivative source.

Native bilingual content means writing twice: one version that sounds American and one that sounds Mexican, each written for its own reader. Ask directly who writes each language, and whether they are native speakers or a translation tool with a human polish. The difference shows up in the copy, and the engines can tell.

Do they have proof — screenshots, not promises?

Since the whole business is about citations, the proof is citations too. An agency that has already gotten an engine to recommend a client can show you the screenshot. One that has not will talk about "results" in the abstract.

Watch for these red flags:

• They talk about "AI ranking" but never show you a real citation.
• They promise you will appear in ChatGPT without running an audit first.
• They present striking numbers with no link to the source.
• They cannot name the engines you already appear in today.

Do they understand that GEO does not replace SEO?

The correct answer is that GEO sits on top of SEO, not in place of it. Everything good SEO does — clear writing, fast pages, semantic HTML, authority — still helps a generative engine. If an agency tells you SEO "no longer matters," be skeptical: they are oversimplifying to sell you something new, and they will likely abandon foundations that still send you traffic.

The bilingual criterion almost no one meets

If your market is Mexico or the U.S. Hispanic audience, your content lives in two languages and so does your competition for citations. Most GEO agencies work in English only or Spanish only. The one that works in both, natively, competes for twice the questions — and covers the buyer who researches in one language and decides in the other.

Before you hire anyone, ask for a snapshot of where you stand today. We run one for free: a 30-minute audit that shows you, with screenshots, what each engine answers when someone asks about your category. It is the same audit any conversation with a GEO agency should start with — ours included.
