How to Check AI Search Accessibility for Your Website in Thailand

Thai customers may ask ChatGPT, Google AI features, Gemini, Perplexity, or Copilot for local recommendations instead of opening traditional search results. If your business doesn’t appear, the problem may be more than rankings: AI systems might not be able to access, interpret, or trust your website. AI Search accessibility means crawlers can reach your pages, read the visible content, understand its structure, and connect reliable facts to your business. It doesn’t guarantee that your site will appear in every answer, but it gives AI systems the information they need to consider and cite it. For broader visibility, see this guide to optimizing Thai websites for AI search engines. A practical audit checks robots.txtrendering, indexing, content structure, schema markup, and local business signals, then compares your results with real prompts in ChatGPT, Gemini, Perplexity, and Google’s AI features. Run these checks on both English and Thai pages if you serve Thai-speaking customers, then start with the technical access tests before reviewing content and prompt results. AI Search accessibility means an AI system can reach your website, read its content, understand what each page means, and find enough evidence to trust or cite it. A site can load perfectly for people yet remain difficult for search systems to interpret. Accessibility has four separate parts: Different crawlers have different jobs. OpenAI’s OAI-SearchBot helps ChatGPT Search find pages for current answers, while GPTBot mainly relates to OpenAI model training. Google-Extended is a robots.txt control token for Google’s AI training systems, not a conventional crawler. ClaudeBot is associated with Anthropic’s data collection, and PerplexityBot retrieves web content for Perplexity’s answer engine. Your robots.txt rules can express preferences for these agents, but don’t assume every crawler or automated tool follows them. Review server logs and security controls as well as the file itself. You can also read how AI search determines brand relevance before deciding which visibility signals to audit. Google Search Console and Bing Webmaster Tools still matter because their indexes often support AI-generated answers. Check both tools for blocked pages, indexing problems, mobile issues, and language or country targeting errors. Your Thailand-focused audit should confirm that: Technical access only makes consideration possible. It doesn’t guarantee rankings, citations, recommendations, or inclusion in any particular answer. Start with a small, repeatable crawl test before changing content. Use the same sample whenever you update your CMS, CDN, or security settings. A technically accessible page can be considered by AI Search, but it still may not earn a citation or recommendation. Choose five to ten representative URLs, including your homepage, main service page, Thai landing page, contact page, and one important article. Add a location page or pricing page if those pages drive customer inquiries. First, open each URL in a normal browser, then compare it with view-source: and the rendered HTML shown in your browser’s developer tools. Check that the page’s main facts appear without a click, login, form submission, or other user interaction. Headings, Thai or English service descriptions, prices, addresses, phone numbers, opening hours, and calls to action should exist as readable HTML. JavaScript-only content can leave some crawlers with an empty shell, especially when content loads after several requests. Server-rendered or static HTML is safer for key information. For each URL, record: You can run a quick header test, then repeat it with a bot user agent, such as curl -A "OAI-SearchBot" -I https://example.com/thai-service/. Review access logs for GPTBot, OAI-SearchBot, Google-Extended, ClaudeBot, and PerplexityBot. Owners should decide which crawlers they permit, since search access and training access can have different policies. A practical ChatGPT crawl check also starts with server access logs. Cloudflare can change the result. Review AI crawl controls, bot protections, managed challenges, rate limits, and markdown delivery settings where available. Also use Google Search Console URL Inspection and Bing Webmaster Tools to compare crawler access with search-engine rendering. A green test proves that a crawler can fetch and read the page. It does not prove that an AI system has indexed, trusted, cited, or included your business. Your XML sitemap should list only canonical, indexable URLs that return 200 responses. Remove redirected, duplicate, thin, broken, and noindex pages, then submit the sitemap in Google Search Console and Bing Webmaster Tools. A canonical tag identifies the preferred version when similar URLs exist. For Thai websites, each Thai or English page should point clearly to its own preferred URL, with language annotations where appropriate. Don’t let a Thai landing page canonically point to an unrelated English page. Treat llms.txt as an optional supporting file. Adoption and impact vary, so it cannot replace robots.txt, ML sitemaps, canonical tags, or standard indexing controls. Clear signals across those established systems give crawlers a more dependable route through your site. Once crawlers can reach your pages, test whether they can interpret the information correctly. AI Search needs clear, self-contained facts it can quote without guessing who you are, where you operate, or what you offer. Review your Thai and English pages as if you were checking a business profile for contradictions. Use one clear H1 for the page, then organize related topics under descriptive H2 and H3 headings. Short answer paragraphs of roughly 40 to 60 words help systems identify direct responses to common searches. Tables can clarify prices or service comparisons, while bullet points work well for eligibility rules, delivery areas, and opening hours. Write for real Thai searches, such as: Add JSON-LD that matches the information visitors can see on the page. Choose the most specific, accurate type, such as Organization, LocalBusiness, Restaurant, Product, Article, BreadcrumbList, FAQPage, or HowTo. Use FAQPage only when genuine questions and answers appear visibly. Never add hidden FAQ text, false reviews, or an unsupported business type. For a Thai business, useful fields may include name, address, telephone, url, openingHours, areaServed, author, datePublished, dateModified, sameAs, and inLanguage. Product and service pages can also include visible. price, priceCurrency, availability, and service areas. Keep the same business name, address, phone number, service names, Thai spellings, English spellings, province, and district names across your website and business profiles. Inconsistent details can split one business into several unclear entities. Visible trust information matters too.
