How to do AEO in 2026? Comparing Popular AI Visibility Tools in Thailand

Master AI Search Optimization (AEO) in 2026. We compare BuildSOM, Profound, and Semrush for the Thailand market to find the best AI visibility tool for your brand.

The Shift from Traditional SEO to AI Visibility

While SEO agencies, due to habitual behavior, stick with their legacy SEO tools, both SEO agencies and their clients are hurt dear to the incapability of household SEO tools like Ahrefs or SEMRUSH, and their insane pricing scheme. In 2026, the digital landscape has shifted toward AI Engine Optimization (AEO). Brands no longer just compete for blue links; they compete for mentions within AI-generated responses. Relying on outdated metrics and overpriced subscriptions prevents businesses from capturing the massive traffic now flowing through generative AI interfaces.

Major Challenges of AI SEO in Thailand

Thailand presents a unique digital ecosystem where local nuances significantly impact AI performance. Navigating AEO in this region requires more than just standard keyword tracking.

• Language Complexity: AI models often struggle with the nuances between formal Thai and colloquial social commerce language.
• Platform Fragmentation: Users in Thailand toggle between Google AIO, ChatGPT, and regional favorites, making multi-platform tracking essential.
• Localization Accuracy: Many tools attempt to scrape Thai results from Western servers, leading to inaccurate data that doesn’t reflect what a local user in Bangkok or Chiang Mai actually sees.
• Budget Constraints: With the rising cost of SaaS, Thai SMEs and agencies need scalable solutions that don’t charge “enterprise” premiums for basic regional tracking.

Analyzing the Top 3 AI Visibility Tools for the Thai Market

We now analyse 3 popular AI Visibility Tool being used for AEO in Thailand: BuildSOM, Profound and Semrush. These tools represent the current spectrum of the market, ranging from specialized AI-first platforms to legacy SEO giants attempting to pivot into the AI space. Our goal is to determine which software provides the most actionable insights for brands looking to dominate AI search results in 2026 without breaking the bank or sacrificing data integrity.

The 2026 AEO Test Case Parameters

To ensure a fair comparison, we designed a rigorous test case reflecting a real-world multi-regional brand scenario. The test case is as below:

• The Assets: A brand holding three domains to promote their brand across different segments.
• The Target: The brand targets both customers speaking English and Simplified Chinese in Thailand, as well as English, Cantonese, and Mandarin speakers in Hong Kong.
• The AI Models: Monitoring is required for ChatGPT, DeepSeek, Google AIO, and Google AI Mode.
• The Scope: 15 questions per language per region (30 prompts in Thailand; 45 prompts in Hong Kong), totaling 75 unique tracking points.
• The Constraint: The brand owner is budget-minded and cannot afford any custom or enterprise plan.

Monthly Cost Analysis: Efficiency vs. Complexity

When evaluating these tools, the price transparency and plan structures vary wildly, especially when dealing with multi-regional requirements.

• BuildSOM: The Standard Plan is needed as there is a total 75 prompts to be monitored. Price is USD229 per month. It offers a straightforward flat-fee structure that covers the necessary volume.
• Profound: The Growth Plan, at USD332.5 per month, is needed as the Starter Plan only supports ChatGPT. Since there are two regions (Thailand and Hong Kong) involved, the total cost per month scales to USD665.
• Semrush: This is the most complex. First, you need to join one of the SEO plans before subscribing to AI Visibility features (Pro Plan at USD139/mo). Semrush charges based on the number of domains. In Thailand, with three domains, three Base plans are needed. In Hong Kong, six Base plans are needed because each Base plan covers only 25 custom prompts. Altogether, Semrush costs USD139 + (USD99 x 3) + (USD99 x 6), totaling USD1030 per month.

AI Response Accuracy and Language Integrity

The value of an AI visibility tool is zero if the data it collects doesn’t match what real users see on their devices.

• BuildSOM: High accuracy. By running non-English prompts on corresponding language settings (e.g., Mandarin on Simplified Chinese devices, Cantonese on Traditional Chinese devices), the results collected are exactly the same as human buyers’.
• Profound: Poor localization. It runs non-English prompts on English-configured devices, resulting in data that is often misleading, culturally disconnected, and useless for regional strategy.
• Semrush: Similar to Profound, it relies on English-centric device configurations for non-English queries, which fails to capture the true local AI response, rendering the data unreliable for the Thai or HK markets.

AI Model Coverage: Who Tracks DeepSeek and Google AI Mode?

To remain competitive, tools must cover a wide range of AI models.

• BuildSOM‘s standard plan includes ChatGPT, Gemini, Google AIO, Google AI Mode, DeepSeek, and Perplexity.
• Profound does not cover Google AI Mode and DeepSeek.
• Semrush only offers ChatGPT, Google AI, Gemini, and Perplexity. DeepSeek and Google AI Mode are not available.

Historical Data and Period Coverage

Tracking AI visibility over time is crucial.

• BuildSOM allows users to analyze AI responses daily for up to 360 days.
• Profound provides all-time data.
• Semrush can only track AI responses for up to 60 days.

Final Verdict: Ranking the Top AI Visibility Tools

The best tool depends on specific needs. BuildSOM is best for multi-regional, budget-conscious brands in 2026. Semrush struggles with a pricing model that is not suitable for the AI era.
