Can Local AI Audits Test Spanish-Language Questions for Bilingual Customers?

Why do Spanish answers differ?

• Fewer Spanish sources. Many local businesses have little or no Spanish content, so assistants have less to draw on and name fewer specific businesses.
• Different sources. Spanish answers may cite Spanish-language media, directories and community sites that English answers do not.
• Language as a requirement. "Dentista que hable español" adds a condition that many English pages do not address.
• Less specific answers. A small 2026 test by a PR agency asked Claude 20 travel questions in English and in Spanish. English answers named specific venues about twice as often.

The last point is an opportunity. Where answers are thin, a business with clear Spanish information has less competition.

How do you build the Spanish question set?

1. Start from real customer questions, from calls, front desk staff and reviews, rather than translating an English list.
2. Use a native speaker from your customers' community to write them. Vocabulary varies: "plomero" and "fontanero" both mean plumber, and "carro" and "coche" both mean car, but different communities use different words.
3. Include mixed phrasing. Many bilingual customers type "dentista near me que acepte Medicaid" or "abogado de accidentes en Houston".
4. Add the language requirement to some questions, such as "que hable español" or "con personal bilingüe".
5. Keep a matching English version of each question, so you can compare like with like.

How do you run the audit?

• Engines: ChatGPT, Gemini, Google's AI Overviews and AI Mode, Perplexity and Copilot all answer in Spanish. Test the ones your customers use.
• Location: set it to your area, or include the city in the question.
• Language settings: run some questions with the interface in Spanish, since some assistants take account of it.
• Repeats: two or three runs per question and engine.
• Record: the answer language, businesses named, whether you appear, whether the answer says you offer Spanish-speaking service, the sources cited, and any errors.

Compare mention rates between the Spanish and English versions. With 20 questions run three times, 60 answers per language and engine, a gap smaller than about 18 points can be noise; a larger gap that repeats the next month is the main finding, because it shows Spanish questions are going to competitors.

Which errors are common in Spanish answers?

Look out for these when you review the results:

• Invented language claims: an answer says a business offers Spanish-speaking service because its owner has a Spanish surname, or because an old review mentioned it.
• Missing language claims: a business with bilingual staff is not described as offering Spanish, because nothing says so in text.
• Wrong business names: assistants translate a business name into Spanish, which makes it hard to find.
• English sources summarised in Spanish, with details lost or changed in translation, such as prices or opening hours.
• Generic advice instead of names: "busque un dentista bilingüe en su zona" rather than any specific recommendation.

Each error points to a fix: clearer language statements, consistent names, or Spanish pages that give assistants a direct source.

What should the audit report show?

Keep the report simple enough for the owner or practice manager to act on:

• the mention rate in Spanish and in English, side by side, for each assistant;
• the questions where you appear in English but not in Spanish;
• the competitors named in Spanish answers, and the sources cited for them;
• any wrong language claims about your business;
• three to five actions, each with an owner.

Repeating the same comparison each month shows whether the gap is closing.

What should a local business publish?

• Spanish pages for key services, written or reviewed by a fluent speaker, not machine-translated word for word. Link them to the English versions with hreflang tags.
• A clear statement of language service: who speaks Spanish, on which days, and for which services.
• Profiles: add a Spanish line to your Business Profile description, and fill in language fields on directories that have them.
• Spanish reviews: ask every customer for an honest review in their own words, and say they are welcome to write in Spanish or English.
• Spanish-language media and community listings relevant to your area.
• Accuracy: never claim Spanish service you cannot provide consistently.

What should a clinic page say about Spanish-speaking providers for AI recommendations?

Health questions often include a language requirement, such as "pediatra que hable español en Phoenix". A clinic page should give assistants and patients clear, specific facts:

• Which providers speak Spanish, by name, on their bio pages, and how. A native or fluent speaker can consult in Spanish. A provider with basic Spanish usually works with an interpreter.
• Which services are available in Spanish, such as appointments, telehealth, lab results and the patient portal.
• Front desk and phone support: whether Spanish-speaking staff answer calls, and when.
• Interpreter services: how patients can request an interpreter for other languages or when no Spanish-speaking provider is available. Many US healthcare providers must offer language assistance under federal civil rights rules, so explain how it works.
• Forms and materials available in Spanish.
• Directory consistency: make sure insurer directories and health directories list the same languages for each provider.

Avoid the vague "Se habla español" on its own. It does not tell a patient or an assistant whether they can see a doctor in Spanish. Specific language information is what gets a clinic named for language-qualified questions. Tracking results across markets is covered in how to track AI recommendations across countries and regions.

What might an illustrative audit show?

Consider an illustrative family dental practice in San Antonio with two Spanish-speaking dentists. For "best family dentist in San Antonio", it appears in some English answers. For "dentista familiar en San Antonio que hable español", it never appears. Answers name a competitor whose Spanish page lists its bilingual dentists by name and cites Spanish reviews on its profile. The practice's site mentions Spanish once, in a footer. It adds a Spanish services page, names its Spanish-speaking dentists on their bios, updates insurer directory language fields and tells every patient they can leave an honest review in Spanish or English. Two months later, it appears in some Spanish answers, with its bilingual dentists described correctly.

What do people ask about Spanish-language AI audits?

Can we just translate our English question set?

Use it as a starting point, but have a native speaker rewrite it. Translated questions often use words customers would not type.

Do assistants answer in Spanish if asked in Spanish?

Generally yes. Some answers mix languages or cite English sources, which is worth recording.

Should we test other languages too?

Test any language a significant share of your customers use, such as Vietnamese, Chinese or Korean, with the same method.

How often should we rerun the Spanish audit?

Monthly alongside the English audit, so the gap between the two can be tracked over time.
