Someone landing at Suvarnabhumi asks their phone for a good dentist near Asok who speaks English and takes walk-ins. A few years ago, they’d scroll Google Maps and compare star ratings. Now, more and more often, an AI assistant gives them two names and a reason for each.

That shift is happening across Bangkok and Southeast Asia, and it changes how local businesses get found. Local SEO still matters, but the goal has moved. You’re no longer just trying to rank in the map pack. You’re trying to be the business an AI confidently recommends.

This is the playbook we use at AgentDee for local AEO in Thailand and the wider region.

What makes local AEO different

Global AEO is about being cited for broad category questions. Local AEO adds three layers that make it harder, and more winnable:

• Location signals: the AI needs to know exactly where you are and which areas you serve.

• Language: buyers in SEA search in Thai, English, Bahasa, Vietnamese and mixed-language queries, and answers differ by language.

• Local sources: AI models lean on regional platforms that global playbooks ignore, such as Wongnai, Pantip, local news sites and country directories.

A Bangkok clinic, restaurant or B2B firm competes against a smaller set of rivals than a global brand does. That means a focused effort can move AI recommendations faster.

1. Treat your Google Business Profile as your source of truth

Google AI Overviews and Gemini draw heavily on Google’s local data, so your Google Business Profile is the starting point for local AEO.

Get the basics exactly right: business name, address, phone, hours, categories and service areas. Then go further. Write a clear description that states what you do, for whom and where. Add products and services with short descriptions. Upload real photos regularly. Answer the questions people ask on your profile.

Most importantly, make sure these details match everywhere else. If your profile says “Sukhumvit 21” and your website says “Asok,” the AI has to guess whether they’re the same place.

2. Win the reviews AI actually reads

Reviews feed AI answers in two ways: the rating itself, and the language inside the reviews. When an assistant recommends a restaurant “known for its khao soi and quiet atmosphere,” it’s often summarizing what reviewers wrote.

Ask happy customers for reviews on Google and on the platforms that matter in your category. For restaurants and cafés in Thailand, that includes Wongnai. For hotels, Agoda and TripAdvisor. For B2B, Clutch or industry directories. Encourage specific feedback rather than “great service,” because specific reviews give the AI concrete details to repeat.

Reply to reviews, especially negative ones. A calm, helpful reply shows up in the same data the AI reads.

3. Show up on regional sources, not just global ones

When we track which sources AI assistants cite for Thai queries, local platforms appear constantly. Pantip threads, Thai news outlets, Wongnai listings, local “best of” roundups and Thai-language blogs often outweigh big international sites.

Map the sources that get cited for your category and city. Then work your way onto them through PR, partnerships, guest contributions, directory listings and genuine community participation. A mention in a respected Thai publication can do more for local AI visibility than a dozen links from generic global blogs.

4. Build for multiple languages properly

Local SEO in Thailand means serving at least two languages, and many SEA businesses need three or more. AI assistants answer in the language of the question, and they pull from content in that language.

That means:

• Separate, well-written pages for each language, not machine-translated copies.

• Hreflang tags so search engines know which version serves which audience.

• Native phrasing that matches how locals ask questions. Thai buyers often search with mixed Thai and English terms, so test both.

• Consistent business details across every language version.

If your English content is strong but your Thai content is thin, expect AI answers in Thai to recommend someone else.

5. Write answer-first content for local questions

Local buyers ask specific questions: “How much does a website cost in Bangkok?” “Which coworking spaces in Thonglor have monthly plans?” “Do I need a Thai company to run Facebook ads?”

Create pages that answer these directly, with the answer in the first two sentences, local prices in THB, named neighborhoods and clear conditions. These pages are easy for AI to quote, and few competitors write them well. Our guide to [How to Write Citation-Ready Content for AI Search] covers the structure in detail.

6. Mark up your location

Add LocalBusiness schema (or a more specific type like Restaurant, Dentist or ProfessionalService) with your address, geo-coordinates, opening hours, area served and sameAs links to your Google profile, Facebook page, LINE Official Account and key directory listings. This ties every version of your business together into one entity. See our [AEO Schema Checklist] for the full list.

7. Track local share of voice by city and language

AI answers vary by location and language, so national tracking hides the real picture. Build a prompt set for each city you serve and each language you sell in. Test questions like “best physiotherapy clinic in Chiang Mai” separately from “best physiotherapy clinic in Bangkok.”

Track how often you’re named, where you appear and which competitors take your place. Our post on [Tracking Your AI Share of Voice] explains how to set this up.

The bottom line

Local businesses in SEA have an advantage most global brands don’t: smaller competitive sets and regional sources that reward genuine local presence. Get your data consistent, earn reviews and mentions where your buyers actually look, and write for the questions they ask in their own language.
