Thailand gambling search and ad rules for SEO teams

The short answer

Gambling advertising is not legal in Thailand. Lexology's advertising guide says it cannot be advertised under Thai law. Law firm Formichella & Sritawat says Section 12 of the Gambling Act can also reach affiliates and creators who share betting links. Thailand's digital ministry blocks URLs at scale. This is a summary of published sources, not legal advice.

Is gambling advertising legal in Thailand?

No, according to every source found. Lexology's "In brief" guide to Thai advertising says gambling cannot be advertised under Thai law. The ad network CliqBetter says there is no legal route for private operators to run online gambling campaigns aimed at Thailand.

Formichella & Sritawat, a Bangkok law firm, goes further. It says a Council of State opinion found the Gambling Act's licensing framework covers physical premises only. So online betting has no authorisation route. In its words, promoting an online bookmaker to a Thai audience means promoting something that cannot be authorised.

Gambling Maps, a compliance brief, lists Google Search Ads, app store ads, TV, radio and sponsorships as banned for Thailand. It is a secondary source. We did not find Google's own policy page in our results.

What does Section 12 mean for affiliates?

Formichella & Sritawat says Section 12 of the Gambling Act 1935 reaches anyone who helps advertise or invites others, directly or indirectly, to join unauthorised gambling. It adds that a creator sharing a betting link may fall under this whatever the payment arrangement. It also says an accurate link without false claims still leaves exposure.

The firm cites Office of Justice Affairs guidance that names social posts carrying gambling links. It also says an affiliate deal built around unlawful promotion is void.

A second law matters. Deputy Minister Nan Boonthida Somchai told the public that sharing or promoting such content can breach Section 14 of the Computer Crime Act, even if done unknowingly, Bangkok Post reported on 22 June 2026.

None of the sources tests a ranking affiliate site against these rules. Treat the risk for review sites as an open question for Thai counsel.

How is Thailand blocking gambling content?

The Ministry of Digital Economy and Society (MDES) reported 945,075 blocked URLs in fiscal 2026, Gambling.com said on the basis of a 6 October statement. AffPapa reports 835,207 of those came through court orders and 109,868 through platform cooperation.

Other figures:

• Bangkok Post: 13,888 links blocked from 1 to 18 June 2026.
• Gambling.com: more than 55,000 blocked from 1 June to 12 July.
• Focus Gaming News: the totals count URLs, not separate sites or operators.

Search is now in scope. Focus Gaming News and Gambling.com both report that MDES plans to work with search engine providers to make illegal sites harder to find. AffPapa adds a planned working group with TikTok and Meta.

Effectiveness is disputed. AlienWP, on 21 October 2026, reported that former MP Sirichoke Sopha said 29 of 30 gambling sites he checked were still reachable in Thailand.

What penalties do the sources report?

The sources do not agree. The table sets them side by side.

Lexology says penalties depend on whether a game sits in list A or list B of the Act. That may explain part of the gap. No source reconciles the figures.

Will the casino bill change search and ad rules?

Probably not for online promotion. The Thaiger says the Entertainment Complex Bill did not address online gambling. Brightside of News says the same. A draft summarised by Global Law Experts bars licence holders from offering online gambling beyond the resort premises.

Status reports conflict. CliqBetter says the Cabinet withdrew the bill on 8 July 2025. The Thaiger says a coalition framework revived it in May 2026 but no new action followed. IGamingToday says an Entertainment Complex Business Act was enacted in the first quarter of 2026. We could not settle this from the sources.

What should an SEO team take from this?

These are points drawn from the sources, not legal advice.

• Treat Thai-language gambling pages as high risk. CliqBetter lists an offshore licence as a false comfort.
• Watch for MDES and search engine changes. They may affect visibility.
• Watch the draft amendment. Lexology says it would name advertising and promotion directly.
• Keep a record of what content is live for Thai users, and who publishes it.

What we could not confirm

• Whether any affiliate or review site has been prosecuted under Section 12 for ranking content. We found no case.
• Which penalty range is correct today. Sources differ.
• Whether the Entertainment Complex law has passed. Reports conflict.
• Google's own current policy text for Thailand. We relied on a secondary brief.
• How MDES's plan to work with search engines will work in practice. No technical detail was published in the sources found.
