Which GEO agency works in both English and Spanish?

An assistant often answers a Spanish question from a different set of sources than the same question in English. A brand that is recommended in English can be absent in Spanish, and the reverse also happens. Visibility has to be measured and earned in each language.

The two languages are also linked. Peec AI analysed more than 10 million ChatGPT prompts and 20 million of the background searches the model runs before it answers, and published the results in February 2026. The study kept only prompts sent from a country where the prompt's language is spoken, such as Spanish from Spain. For non-English prompts, 43% of the background searches ran in English. In 66% of Spanish sessions ChatGPT ran at least one search in English, the lowest share of any language in the study. English pages can therefore feed a Spanish answer, and both versions need to say the same thing about you. The data comes from one analytics vendor's dataset and, given that filter, says little about Spanish speakers in the United States, so treat it as a sample.

Translating the English pages does not solve this. Assistants look for pages that use the words buyers type, and those words differ by country. A page translated from English into generic Spanish matches a buyer in Mexico poorly and a buyer in Madrid no better. Our guides on multilingual GEO and GEO in Spanish cover the mechanics.

The market is large enough to justify the work. Pew reports 68 million Hispanic residents in the United States in 2024, and 68% of them spoke Spanish at home. Whether your own buyers research purchases in Spanish is a separate question. Sales conversations and your own analytics answer it; a measurement of assistant answers does not. Our guide to GEO in the USA explains how to check.

Few agencies are set up for this. In September 2026 we checked the 60 GEO agencies and consultants that ChatGPT, Perplexity and Google AI Mode had cited in our runs. Nine had a website in two or more languages. None had four or more. Our own site is written in nine.

Four things distinguish a two-language program from an English program with a translated site. Ask which of the four are in the quote.

Send the five questions in the table to every agency on your shortlist and compare the replies in writing. A useful answer names a number, a country or a source.

The five questions cover only the second language. Our full list of ten questions covers evidence, pricing and responsibility, with our own answers to each.

GET-GEO.AI is a GEO agency founded by Dmitry Filippov, who has worked in search optimization since 2009. The site is written in nine languages: English, Spanish, Russian, German, French, Italian, Chinese, Hindi and Hebrew. Some buyers call this work AEO (answer engine optimization) or AI search optimization. We do it for companies that want to be recommended by ChatGPT in the United States, including the US Hispanic market, and in Spanish-speaking countries.

We run English and Spanish as two tracks of one program. Each starts with its own baseline of 30–50 buyer prompts, repeated in clean sessions (logged out, or a temporary chat with memory off) across ChatGPT, Perplexity and Gemini. We report two numbers: citation rate (the share of prompts where an assistant links to your page) and share of voice (your share of the brand mentions on the same set).

The work then follows three layers. Access comes first: robots.txt, redirects and server-rendered text, so that crawlers can read both language versions. Content and entity come next: a page for each prompt worth winning, written in each language for the target country, and one consistent description of the company everywhere it appears. Independent sources in each language come last and take longest. During a pilot we remeasure every two to four weeks.

Spanish pages are written by a native speaker. For US programs we write a neutral US register and do not import the Spanish of Spain. For Mexico or Spain the pages use that country's vocabulary from the first line. Other Latin American (LATAM) markets follow the same rule: one prompt set and one set of pages per country.

We apply the method to our own site first. On 17 August 2026 we asked ChatGPT, in a clean session without login, for the best GEO agency that works with English and Spanish. It named GET-GEO.AI as its top pick and cited our site. The screenshot, the prompt and five earlier runs on other language pairs are in our case study. It is one run on our own brand.

Two commitments apply to every engagement. If citation rate and share of voice have not moved after 90 days, we say so first, and you choose between a free diagnostic month, a change of scope or a stop. The prompt set, baseline, logs and reports stay with you. The method is described in how we measure.

A two-language program is priced inside the same published ranges as a one-language one. One pilot covers one language pair, so English and Spanish fit in a single pilot at $2,500–6,000. The table in this section lists the four tiers.

You receive a fixed quote inside the relevant range before work starts. The price depends on scope: the number of languages, prompts and pages. With a second language the deep audit sits at the top of its range. The free audit covers one language.

Published prices are still unusual. Of the 60 cited agencies we checked in September 2026, 28 published any GEO price. Our pricing guide has the medians and what each tier should include.

The free audit is the place to start. Email hello@get-geo.ai and tell us which language to test first. You receive the ten answers and the proposed changes in writing.

There are two cases where another provider is the better choice. If neither is yours, ask two or three other agencies to answer the ten prompts from your free audit, and keep their replies next to ours.
