Key Points
- Google’s expanded “good policy health” requirement across all gambling and gaming advertising categories took effect on 14 September 2026, not October.
- From 7 October 2026, Google will revoke certifications for online gambling-promoting content targeting Croatia; operators advertising their own products are explicitly unaffected.
- Manager Accounts overseeing significant volumes of non-compliant gambling advertisers now risk losing certification eligibility across their entire managed portfolio.
Most coverage of Google’s gambling advertising changes has framed them as something arriving in October. The more consequential shift, a complete overhaul of who qualifies for certification and what history Google now checks before granting it, took effect on 14 September 2026. October brings a separate, narrower measure targeting Croatia specifically. Conflating the two has left a lot of operators, affiliates and agencies with an inaccurate picture of their actual exposure.
The September Change: Compliance History Replaces Document Submission
Before 2026, certification for gambling advertising was largely a documentation exercise. You held a valid licence for the target market, submitted it, and Google reviewed it. The March 2026 update changed that logic fundamentally, and the September expansion finished the job.
Google’s notice in July 2026 was clear that starting from 14 September, all accounts wishing to advertise in any gambling and games categories need to have good policy health status. Licensing credentials are required, but alone do not suffice anymore. Google needs to see that the advertiser has been complying with the policies properly throughout his/her tenure. This has become a requirement for all gambling and gaming categories.
The domain requirement has become stricter along with this. The update in Google’s March 2026 certification notice made it clear that the website should not be a free platform, or should not have any third-party root domain or any domain having nothing to do with gambling. Also, the certification process is specific to the market and the domain. Launching in a new market or from a new domain means a fresh application altogether.
The Timeline That Built This Moment
The September change did not arrive suddenly. Google has been building toward it through a sequence of policy updates across 2026, each one adding a new compliance layer.
January 2026 saw the introduction of the first iteration of the certification eligibility criteria. In March 2026, the good policy health criterion was codified along with the extension of MCC’s responsibility for it. In July 2026, there was the announcement of the extension of the requirements to each and every gambling and gaming sector. In August, Google redesigned its certification application process worldwide, obliging all new candidates as of 26 August to use updated paperwork and to keep their licenses valid and up-to-date with the relevant regulatory bodies.
What the MCC Rule Actually Says?
The Manager Account provision has attracted the most industry attention, and also the most misreading. The March 2026 policy states that MCCs with a significant volume of gambling certificates revoked from accounts under their management, or where significant volumes of managed accounts are found to have violated the gambling policy while relying on a certificate, will lose the ability to apply for new online gambling certificates and may have existing certifications revoked.
Two words matter enormously there: “significant volume” and “may.” Google has not said that one account’s violation automatically strips the entire MCC of certification. The trigger is a pattern at scale, repeated and significant non-compliance across multiple managed accounts, not a single incident. Agencies running clean portfolios with isolated incidents are not automatically at risk. What has changed is that the compliance behaviour of every advertiser inside a shared management structure now contributes to a collective record that Google monitors. For large affiliate networks managing dozens of gambling clients from one login, the practical implication is real: one part of the portfolio that runs repeatedly dirty campaigns is no longer only that advertiser’s problem.
Croatia: Affiliates Out, Operators Stay
The October 7 Croatia restriction is a separate decision, narrower in scope than most reporting has acknowledged. Google’s Croatia policy update states that effective 7 October 2026, the updated policy will disallow all promotion of online gambling-promoting content targeting Croatia, with all existing certifications for advertisers of that content revoked and new applications no longer accepted. Then comes the sentence most outlets missed: “Promotion of online gambling will not be affected by this policy update.”
The practical distinction is this: affiliates and aggregators, those running comparison sites or promotional content that directs users toward gambling platforms, lose access to paid search and display campaigns in Croatia from 7 October. Licensed operators advertising their own services are not covered by this restriction. According to Google’s own policy definitions, gambling-promoting content covers aggregator or affiliate content that encourages engagement in gambling; it does not cover operators advertising their own licensed products.
Croatia’s national advertising rules, which came into force on 1 January 2026 following amendments to the Croatian Gambling Act, introduced one of Europe’s strictest advertising regimes, including a prohibition on online gambling advertising between 6 am and 11 pm, bans on print and outdoor advertising, and restrictions preventing electronic publications from hosting content with direct links to gambling operators’ sites. Google’s October change lands on top of a market already heavily restricted by national law; the two measures are related in context but separate in origin.
The controversy around the Croatia Football Federation’s deal with US prediction markets operator Kalshi, which used Luka Modrić as its public face across social media, sits uncomfortably against that backdrop. Local outlets questioned why no Croatian regulator moved to cancel the partnership, given that prediction markets sit in an unregulated grey area nationally. Strict advertising rules for affiliates; no apparent enforcement for sports sponsorships. That inconsistency is not Google’s to resolve, but it does illustrate how far national enforcement still lags behind the advertising restrictions on paper.
Social Casino Stays Separate
Social casino continues to be considered a separate certification path by Google. Games that mimic gambling but don’t offer any monetary reward to players need separate certification from online gambling campaigns, for markets like India, Hong Kong, Malaysia, Thailand, Vietnam, Taiwan, and South Korea. The August 2026 update for all global markets saw the division of certifications for online gambling and social casino into separate accounts, thus creating two separate compliance paths for advertisers in both these categories.
Expert Analysis
We would argue that what Google is constructing, policy update by policy update, is a compliance infrastructure that national regulators have repeatedly requested but have been structurally unable to build themselves. The good policy health standard does what no licensing regime can do across borders: it ties ongoing advertising access to a running compliance record, not a document filed years ago.
The MCC provision is where this gets genuinely worth debating. Holding agencies accountable for the aggregate compliance behaviour of every advertiser they manage is a policy instrument with a sharp edge on both sides. It creates a real pressure on agencies to monitor client behaviour more actively, which is probably the intended effect. But it also creates a rational business incentive to quietly exit any client relationship that carries compliance risk, rather than work through remediation. Concentration of gambling advertising in fewer, larger, and more conservative hands is the likely long-term result. Whether that serves player protection or simply reduces competition is a question worth asking. Google has effectively become a gatekeeper for an entire global advertising category, setting compliance standards, enforcing them unilaterally, and deciding who loses access, without the appeals transparency or regulatory mandate that normally come with that level of authority. That may be the most efficient solution available. It does not make it a neutral one.
