Local Keyword Research Thailand: How to Find the Right Thai and English Keywords
Effective local keyword research Thailand requires a fundamentally different approach than standard Western SEO. Thailand’s digital landscape is unique: consumers switch between Thai-script searches and English queries depending on their context, device, and intent. If your keyword strategy ignores this bilingual reality, you are leaving significant organic traffic on the table. This guide walks you through the practical steps, tools, and mindset shifts needed to build a keyword foundation that actually works in the Thai market.
Why Thai Keyword Research Is Different from Standard SEO
Thai keyword research presents challenges you simply do not encounter in monolingual markets. Consider these key differences:
- Script complexity: The Thai alphabet has no spaces between words. Thai NLP (natural language processing) tools must segment text before they can analyse search volume, which means Western tools often return inaccurate data for Thai-script queries.
- Code-switching behaviour: Thai users frequently mix English and Thai in a single search, for example “ร้านอาหาร Bangkok ราคาถูก” (cheap Bangkok restaurant). Your keyword list must capture these hybrid queries.
- Transliteration variance: Place names and brand terms are romanised inconsistently. “Sukhumvit”, “Sukumwit”, and “Sukhumvit Road” all target the same audience but return different volume data.
- Regional dialects: Northern Thai (Kham Mueang) and Southern Thai dialects produce different informal search terms that differ from Central Thai used in Bangkok.
Understanding these nuances is the starting point for any serious Thai SEO keywords strategy.

Building a Bilingual Keyword Strategy for Thailand
A robust bilingual keyword strategy maps every core topic to at least two keyword clusters: one in Thai script and one in English or Romanised Thai. Here is a practical framework:
Step 1: Define Your Core Topics in Both Languages
Start by listing your main products or services in English. Then, work with a native Thai speaker or a professional translator to produce the equivalent Thai terms. Do not rely solely on Google Translate — it frequently misses colloquial phrasing. For example, “accounting services” is formally “บริการบัญชี” but Thai SME owners often search “รับทำบัญชี” (literally “accept doing accounts”), which has far higher search volume.
Step 2: Use the Right Keyword Research Tools
Not all keyword tools handle Thai equally well. Here are the most reliable options:
- Google Keyword Planner: Set the target country to Thailand and language to Thai. It handles Thai script reasonably well and gives local search volume directly from Google’s index.
- Google Search Console: Invaluable for discovering the exact queries (in both Thai and English) that are already driving impressions to your site.
- Ahrefs and Semrush: Both platforms have improved Thai-language data significantly. Use them for competitor gap analysis — enter a local competitor’s domain and filter by Thai-language keywords.
- Google Trends: Compare Thai-script and English versions of the same keyword to understand seasonal demand and regional interest across Thailand’s provinces.
- Keyword Surfer (Chrome extension): Useful for quick on-the-go volume checks while browsing Thai SERPs.
For authoritative guidance on how Google processes Thai-language content, the Google Search Essentials documentation provides foundational best practices that apply across all languages.
Step 3: Analyse Local Search Intent
Search intent in Thailand is often hyper-local. A user searching “dentist Thonglor” has very different intent from one searching “dental tourism Thailand cost”. Map each keyword to one of four intent categories:
- Informational: “วิธีทำ SEO” (how to do SEO)
- Navigational: “Central World Bangkok hours”
- Commercial investigation: “ร้านกาแฟ Specialty Coffee เชียงใหม่ ดีไหม” (is specialty coffee in Chiang Mai good?)
- Transactional: “book hotel Pattaya Beach cheap”
Matching content type to intent is just as important in Thai SEO as it is in any other market.
Bangkok Keyword Targeting: Going Hyper-Local
Bangkok keyword targeting deserves its own section because Bangkok dominates Thai internet usage. With over 10 million residents and one of the highest smartphone penetration rates in Southeast Asia, Bangkok search behaviour is highly localised. Users search by BTS station, neighbourhood (แขวง), and even specific shopping mall. Effective Bangkok keyword targeting means:
- Including BTS and MRT station names in your location keywords (e.g., “co-working space Asok”, “gym near Phrom Phong BTS”)
- Using district names in Thai and English (e.g., “สุขุมวิท” and “Sukhumvit”, “สีลม” and “Silom”)
- Targeting mall-specific searches where relevant (e.g., “Japanese restaurant EmQuartier”)
- Building separate landing pages for multiple Bangkok districts if your business serves more than one area
Outside Bangkok, apply the same logic to major cities: Chiang Mai, Phuket, Pattaya, Khon Kaen, and Hat Yai each have distinct local search behaviours that reward city-specific keyword pages.

Local Keyword Research Thailand: Competitor Analysis in the Thai SERP
One of the fastest ways to accelerate your local keyword research Thailand process is to study who already ranks in Thai SERPs. Open a private browsing window, set your Google location to Thailand, and search your primary terms in both Thai and English. Take note of:
- Which local business pages consistently appear in the top 10
- Whether Google Business Profile listings dominate above organic results (a sign of strong local pack competition)
- The exact title tag language — Thai, English, or mixed — used by top-ranking pages
- Featured snippets in Thai script, which indicate structured informational queries
Export competitor keywords using Ahrefs Site Explorer or Semrush Organic Research, filter by Thai geographic data, and identify keyword gaps your current content does not address. This SERP-level intelligence is often more actionable than raw keyword volume data.
Prioritising Your Thai SEO Keywords
Once you have compiled a comprehensive keyword list, prioritise using a simple scoring matrix:
- Search volume: Is there measurable demand? Even 100 monthly searches can be highly valuable for a niche local service.
- Keyword difficulty: Thai-language keywords frequently have lower competition than their English equivalents, making Thai-script content an efficient investment.
- Business relevance: High volume means nothing if the searcher is not a potential customer.
- Conversion potential: Transactional and commercial-intent keywords should receive priority content investment.

Common Mistakes in Thai Keyword Research
- Targeting English only: If your audience includes Thai nationals, ignoring Thai-script keywords means ignoring the majority of your potential market.
- Using automated translation without native review: Machine-translated keywords often sound unnatural to native speakers and miss high-volume colloquial terms.
- Ignoring long-tail local queries: Thai users are increasingly specific in searches. Long-tail keywords like “ร้านอาหารเจ ใกล้ฉัน สุขุมวิท” (vegetarian restaurant near me Sukhumvit) convert at higher rates despite lower volume.
- Not updating keywords seasonally: Thailand has distinct tourism seasons and national holidays (Songkran, Loy Krathong, King’s Birthday) that create significant search volume spikes for relevant businesses.
Frequently Asked Questions
Do I need to target both Thai and English keywords for my Thai website?
Yes, in most cases. The right balance depends on your target audience. If you primarily serve Thai nationals, Thai-script keywords should take priority. If you target expatriates, tourists, or international businesses, English keywords may drive more qualified traffic. For most businesses, a bilingual keyword strategy that covers both scripts delivers the broadest reach and the strongest local SEO results.
Which keyword research tool works best for Thai-language keywords?
Google Keyword Planner remains the most reliable starting point because its data comes directly from Google’s search index. For competitive analysis, Ahrefs and Semrush have significantly improved their Thai-language databases and are worth using alongside Keyword Planner. Always cross-reference volume data across at least two tools before making major content decisions.
How do I handle keyword research for multiple cities in Thailand?
Create separate keyword lists for each city you want to target. Bangkok, Chiang Mai, Phuket, and Pattaya each have distinct search behaviours and competitive landscapes. Build city-specific landing pages optimised for local terms — for example, a separate page for “co-working space Chiang Mai” and another for “co-working space Bangkok” — rather than combining all locations on a single page.
Are Thai-language keywords less competitive than English keywords in Thailand?
Generally, yes. Many businesses operating in Thailand focus their SEO efforts on English content, which means Thai-script keywords often have lower keyword difficulty scores. This represents a significant opportunity: by investing in well-written Thai content targeting relevant local keywords, smaller businesses can outrank larger competitors who have neglected the Thai-language SERP.
How often should I update my Thai keyword research?
Review your keyword strategy at least once every six months, and more frequently if your industry is seasonal or trend-driven. Thailand’s tourism sector, for instance, sees dramatic keyword volume shifts around Songkran in April, the high tourist season from November to February, and major public holidays. Google Trends is a free and effective tool for monitoring these seasonal shifts in Thai search demand.
