Search in Thailand is moving into AI answers. Google AI Overviews, ChatGPT, Gemini and Perplexity now answer Thai queries directly, and one Bangkok study of 1,200+ Thai questions found 70% of AI answers cited zero Thai domains. Brands that want to appear in those answers need SEO built for entities, structured data and citations, on top of classic rankings.
Bangkok has a deep bench of agencies selling exactly that. The eight below run AI SEO, GEO (generative engine) and AEO (answer engine) programs from Bangkok offices, with named leaders, published methods and track records in Thai and English search.
Each agency was assessed on five areas: depth of AI search services, proof of results, team and leadership, pricing transparency and credibility in the Thai market. Scores run out of 10.

How to Choose an AI SEO Agency in Bangkok
- Ask for an AI visibility baseline. A strong agency measures how frequently your brand appears in ChatGPT, Gemini, Perplexity and Google AI Overviews before starting work.
- Check Thai language depth. AI answers in Thai pull from a small pool of Thai sources, so content quality in Thai matters as much as English.
- Look for entity and schema work. Knowledge Graph, structured data and author signals drive AI citations.
- Agree on reporting. Monthly reports should cover AI citations and AI referral traffic alongside rankings and leads.
- Avoid ranking guarantees. AI answers change daily; trustworthy agencies promise process and measurement.
- Clarify link building standards. Agree on site quality, relevance and disclosure for any paid placements.
