SEO versus GEO in Thailand: what changes and what does not

A clear comparison of search engine optimisation and generative engine optimisation for Thai businesses, with one measurement model for both.

The short answer

SEO and GEO share the same foundation: useful pages, crawlability, clear entities and independent authority. SEO measures visibility and visits from search results. GEO samples whether AI answers mention or cite the business. Neither should be sold as a guaranteed rank or citation.

The foundation is shared.

Search engines and answer engines both need to retrieve and interpret information. Clear service ownership, stable URLs, descriptive headings, factual business details, structured data and independent references help both. There is no magic schema property that makes a company the preferred AI answer.

The result format changes the content job.

A search result can send the buyer to a page before the question is fully answered. An AI response may summarise the decision without a click. That raises the value of direct definitions, comparison tables, dated methods, source links and explicit limitations. These formats also help people, which is why the work should not be treated as content for robots.

Thailand adds language and entity choices.

Decide which questions deserve Thai, English or genuinely separate pages. Keep the business name, address, services and ownership consistent across the website and independent profiles. A translated page should match the intent and responsibility of the original, not merely repeat its words.

Measure a funnel, not a vanity score.

For search, record impressions, clicks, landing pages and qualified enquiries. For AI answers, fix the eligible prompt set and record valid answers, mentions, citations and referred visits. Connect both to the same contact attribution. A mention without a visit can still have brand value, but it is not a lead.
