Thailand is Southeast Asia's second-largest economy and one of the world's most visited countries. Tourism, hospitality, medical and wellness travel, automotive and electronics manufacturing and a fast-growing e-commerce scene all compete for attention online. The brands that win are the ones travelers and Thai buyers find first on Google.co.th and inside AI answers.
Why Google runs search in Thailand
StatCounter records Google at about 99% of search traffic in Thailand as of late 2026, with Bing under 1% and every other engine near zero. DataReportal counts about 68 million internet users, roughly 95% of the population, and about 97 million mobile connections. Roughly 56% of web traffic comes from phones, so Google.co.th on mobile is where most Thai discovery happens. That same Google presence feeds AI Overviews, which now appear on many Thai-language commercial queries.
Languages and how people search in Thailand
Thai is the language of search for consumers and most domestic business, and it brings real technical challenges: no spaces between words, so Google's word segmentation and your page rendering both have to be handled carefully. English matters for tourism, hospitality, medical travel, international schools and multinational B2B buyers in Bangkok. Most commercial sites need Thai and English with correct hreflang, and keyword research must be done natively in Thai, since translated keyword lists miss the phrasing Thais actually type.
How AI search is changing buyer behavior in Thailand
Thais have taken to ChatGPT and Gemini quickly, and Meta AI now sits inside the Facebook and Instagram apps that dominate daily screen time, with LINE close behind for sharing. A traveler asks AI for the best dental clinic in Bangkok, a factory buyer in Rayong asks for a reliable packaging supplier, and the assistant answers with a shortlist. Google AI Overviews add a second layer above classic results. Brands cited in those answers earn consideration before anyone taps a link.
What it takes to rank on Google and get cited by AI
Start with the technical layer: fast mobile pages, clean crawl paths, correct Thai and English hreflang, proper Thai fonts and line breaking, and complete Organization, LocalBusiness and Product schema. Next, Google and AI models need to see your brand as one consistent entity across your site, Google Business Profile, LINE Official Account, Facebook page and Thai directories. Finally, content has to answer specific questions with details AI can quote, such as prices in baht, opening hours, locations and credentials.
Local SEO across Thailand
Bangkok is the capital and the center of finance, retail, healthcare and corporate headquarters, with Nonthaburi and Samut Prakan forming its suburban and industrial ring. Chiang Mai leads the north with tourism and digital services, Phuket and Pattaya drive resort and hospitality demand, and Chonburi and Rayong anchor the Eastern Economic Corridor's automotive and electronics plants. Khon Kaen and Hat Yai serve the northeast and south. We build Google Business Profiles and city pages for each so you show up in local packs and maps.
