Search behavior has shifted—fast. ChatGPT, Perplexity, Google AI Overviews, and Google AI Mode are now answering the questions that used to drive traffic to websites. Brands that show up in those AI-generated responses are capturing attention at the very top of the funnel. Those that don’t? Increasingly invisible.
For marketing teams in Thailand, this has made finding a capable AI Search Agency a real priority. The discipline goes by a few names, such as generative engine optimization, answer engine optimization, and AI overview optimization, but the core challenge is the same: ensuring AI platforms understand, trust, and cite your brand when users ask relevant questions. Some agencies call it AIO agency work. Others position themselves as a GEO agency. The terminology varies; the need doesn’t.
Thailand has a growing number of agencies building genuine capability in this space. This guide covers 12 agencies worth knowing about: what they do, where they specialize, and who they tend to work well for. Use the table below for a quick overview, or scroll through the full profiles.
