AI Mode and iGaming SEO: what the data actually shows
Most coverage of Google AI Mode reads the same way: traffic is falling, zero-click is the future, optimise for citations. What is missing is a clear-eyed look at what AI Mode actually means for iGaming specifically, because the gambling vertical does not behave like general search.
The YMYL classification and the regulatory environment both change things. And there is at least one confirmed piece of Google policy around AI features that has real implications for this industry, and that almost nobody is discussing properly.
This covers what is verified, what the data sources actually say, and what remains genuinely uncertain.
What AI Mode is
AI Mode is Google's full conversational search experience, powered by Gemini. Unlike AI Overviews, which appear alongside traditional organic results, AI Mode replaces the standard results page with an AI-generated response. Users get a synthesised answer with cited sources and can ask follow-up questions in a chat format.
It launched in Google Labs in May 2025. By early 2026 it had reportedly reached 75 million daily active users across more than 40 markets and 53 languages. That figure comes from industry tracking rather than Google's own published data, worth noting. But the scale is real and the growth is not in doubt.
The mechanism matters for SEO. AI Mode uses what Google calls a "query fan-out" approach: it issues multiple related searches simultaneously across subtopics and data sources to build its response. Sites are cited at the content chunk level, not the page level. A well-structured section of a page can be pulled independently of the page's overall ranking position.
One thing Google has been explicit about: their own Search Central documentation states there are no additional requirements to appear in AI Overviews or AI Mode beyond standard SEO best practices. No special schema, no new files, no AI-specific markup. The foundation is the same.
The confirmed fact most iGaming SEOs have missed
Google does not show ads in AI Overviews or AI Mode for gambling.
That is documented policy, directly in Google Ads Help. Gambling sits alongside adult content, alcohol, financial services, healthcare, and politics as verticals explicitly excluded from advertising within AI features.
For most verticals, showing up in AI Mode is now a paid acquisition channel as well as an organic one. Google has been rolling out ads within AI features, with brands able to appear inside AI-generated responses if they use broad match and meet relevance thresholds. For gambling, that option does not exist yet. The organic citation route is the only path within the AI feature itself.
Why this matters commercially
In non-gambling verticals, paid placements inside AI Mode create competitive pressure that shapes the entire surface. In gambling, there are currently no ads competing within the AI response. Organic citation, where it happens, is not pushed aside by paid placements in the same interface. Whether that is an advantage or simply reflects lower AI feature coverage for gambling queries is an open question, and that is the honest answer.
What remains unknown: whether Google applies restrictions to organic gambling content within AI Mode and AI Overviews beyond the ad exclusion. The ad exclusion is confirmed policy. Whether informational gambling queries trigger AI features at the same rate as other verticals, and whether those responses cite gambling sites with the same frequency, has not been documented publicly. This is a genuine gap in available data, not a settled question.
What the zero-click data actually says
The click data around AI features is often cited loosely. The sources matter.
Semrush data from September 2025 puts the zero-click rate in AI Mode sessions at 93%. Growth Memo's analysis from October 2025 found that in 75% of AI Mode sessions users never left the pane at all. These are the AI Mode-specific figures.
The Seer Interactive study that circulates most heavily in SEO discussions covered something different. Seer tracked 3,119 informational queries across 42 organisations, spanning 25.1 million impressions from June 2024 to September 2025. Their finding: organic CTR drops 61% when an AI Overview appears, falling from 1.76% to 0.61%. They also found that brands cited inside the AI Overview earn 35% more organic clicks and 91% more paid clicks than non-cited competitors on the same queries.
Two caveats apply before applying this data to iGaming strategy.
Caveat one: query type
The Seer study covered informational queries only. That is the content category most exposed to AI Overview disruption. Commercial and transactional queries, the ones where affiliate commission models actually generate revenue, trigger AI features less often. Ahrefs data from November 2025 showed Shopping queries have AI Overview coverage of just 3.2%, compared to Science at 43.6% and Health at 43%. Gambling comparison and sign-up content sits closer to the commercial end of that spectrum. The informational CTR data does not map cleanly onto commercial iGaming traffic.
Caveat two: commercial query insulation
Better Collective co-CEO Jesper Søgaard said directly on a Q2 2025 earnings call, reported by iGB Affiliate in September 2025, that AI Overviews had not produced a significant effect on his company's performance. His explanation was specific: "Google is clearly prioritising the paid ads over the AI overviews whenever it relates to commercial keywords." For high-intent gambling queries where paid competition is dense, the AI Overview is pushed down the page. The commercial SERP structure for iGaming may be more insulated than the Seer data suggests.
What the SERP data shows for iGaming
The more documented story is what has happened to iGaming SERP composition over the past eighteen months, and this is not primarily an AI Mode story.
In September 2025, iGB Affiliate published an investigation drawing on multiple industry sources. An experienced affiliate executive described the shift: "Eighteen months ago, if you typed 'best online casinos' you'd see ten gambling websites. Today, you get three affiliates, Trustpilot, and four operators." The source spoke anonymously but the observation tracks with what SERP monitoring has shown across major gambling queries. Authority is consolidating. Smaller affiliates are losing page one positions to larger brands with stronger E-E-A-T signals.
The same investigation included a separate anonymous operator describing organic traffic as "in freefall, maybe 50% down year-on-year." That figure is one operator speaking privately and should not be treated as an industry average. But the direction is consistent across multiple sources.
These shifts are not primarily driven by AI Mode. They reflect the cumulative effect of the algorithm updates through 2025 and into 2026, the authority consolidation patterns documented in the March 2026 double update, the YMYL quality tightening, the devaluation of scaled AI content without editorial oversight. AI Mode is a factor in the broader landscape, but it is not the primary cause of what is happening to iGaming SERPs right now.
The YMYL dimension
Nothing about Google's approach to gambling content changes with AI Mode. It is the same framework applied to the same content in a new surface.
Gambling sits alongside health and finance as the highest-scrutiny YMYL category. Quality rater guidelines have been consistent on this for years. What AI Mode adds is that content selected for citation in a synthesised response is not just evaluated for ranking; it is folded into an answer that users may treat as authoritative without clicking through. The practical quality bar may be higher.
What to actually do
The strategic response has to be calibrated to what the data actually shows, not the general AI Mode narrative.
Do not rebuild your content strategy around AI Mode citation for commercial gambling queries yet
The data on whether commercial gambling queries trigger AI Mode, and whether those responses cite affiliate or operator content at meaningful rates, is not available. The informational query data is real. Its applicability to commercial iGaming content is not established.
Do take the SERP composition shift seriously, because it is already happening
The consolidation in iGaming SERPs is well-documented and is happening independent of AI Mode. Sites with weaker E-E-A-T signals, thinner content, and less established topical authority are losing ground. That trend is more immediate than the AI Mode question.
Build content that is citable
Clear heading structures with direct answers under each H2 and H3. Original observations or data where possible. Named authorship. FAQ sections structured around specific questions. This is the same content quality standard that has always separated rankable content from thin content, applied with awareness that extraction surfaces have changed.
Understand the paid exclusion when planning
If you are managing SEO alongside paid for an iGaming brand, the absence of gambling ads within AI features is a real constraint. There is no AI Mode placement to supplement organic exposure within the feature itself. That shapes where resource goes.
Watch the AI Mode coverage question
The gap in available data is whether gambling queries trigger AI Mode at lower rates than other verticals, and whether YMYL classification affects organic citation frequency. As this becomes clearer from Search Console data and third-party tracking, the strategic picture will sharpen. The data is not there yet to make confident calls.
Key takeaways
- Google explicitly excludes gambling from ads in AI Overviews and AI Mode. This is confirmed policy in Google Ads Help, not inference.
- The 93% zero-click rate for AI Mode comes from Semrush. The Seer Interactive study covers AI Overviews on informational queries only. These are different things and are frequently conflated.
- The Seer data on CTR decline applies primarily to informational content. Commercial gambling queries sit closer to the low-AI-Overview-coverage end of the spectrum.
- Better Collective's CEO confirmed on a public Q2 2025 earnings call that AI Overviews have not significantly affected their performance on commercial keywords, because paid ads take priority.
- The biggest documented disruption in iGaming search right now is authority consolidation driven by sustained algorithm tightening, not AI Mode specifically.
- Vertical-specific data on AI Mode citation rates for gambling content does not yet exist at a meaningful scale. Any strategy built on the assumption that iGaming behaves like general search in AI Mode is built on incomplete information.
