What Happened: The 40,000-Keyword Study That Changes Everything
According to a Moz Whiteboard Friday analysis published on February 20, 2026, data from STAT — one of the industry's leading rank tracking platforms — shows that Google AI Mode's top 10 URLs share only a 12% overlap with traditional organic search results across a dataset of 40,000 tracked keywords.
The finding is significant because it confirms what many SEO professionals have suspected: Google AI Mode is not simply repackaging organic results into a conversational format. It is pulling from a different set of sources, using different selection criteria, and presenting information in a fundamentally different way.
Compare that 12% figure to AI Overviews, which share an 88% overlap with organic search results. AI Overviews essentially pull from the same pool of ranked pages and summarize them. AI Mode, by contrast, appears to operate with its own logic — selecting sources based on topical depth, entity authority, and content structure rather than traditional ranking signals alone.
This study arrives alongside corroborating data from Ahrefs, which analyzed 730,000 AI response pairs and found only 13.7% citation overlap between AI Mode and AI Overviews. When researchers looked at just the top three citations from each, overlap rose slightly to 16.3% — still remarkably low.
Meanwhile, SE Ranking independently found that only 14% of URLs cited by AI Mode rank in the organic top 10. Perhaps most striking: when running the same query three times, AI Mode returned overlapping results with itself just 9.2% of the time — pointing to extreme result volatility.
Why This Matters for SEO Professionals
Google AI Mode now reaches more than 75 million daily users across 200+ countries. It runs on Gemini 2.5 and is rapidly expanding its capabilities — from agentic shopping to AI-powered phone calls to local businesses. It is not a niche feature. It is becoming a primary search interface.
The 12% overlap figure means that ranking on page one of organic Google no longer guarantees visibility in this growing channel. SEO professionals now face a world with two distinct Google search surfaces that reward different content properties.
Who Is Affected
- Content publishers: Ranking number one in organic search may mean nothing in AI Mode. Publishers optimizing only for traditional rankings risk invisibility in conversational search.
- E-commerce brands: AI Mode's agentic shopping features mean products need to be discoverable by AI agents, not just human searchers. Structured product data and entity clarity are now essential.
- B2B companies: LinkedIn recently reported a 60% drop in non-brand organic traffic due to AI search cannibalization. B2B brands dependent on informational content for lead generation are especially vulnerable.
- SEO agencies: Client reporting now needs to account for AI Mode visibility as a separate metric. Traditional rank tracking alone paints an incomplete picture.
The Zero-Click Challenge
The traffic implications are stark. Around 93% of AI Mode sessions end without a click to an external website, compared to 43% for AI Overviews and 34% for traditional search. Users spend an average of 49 seconds in AI Mode versus 21 seconds in AI Overviews — they are getting deeper answers and are less inclined to leave.
There is a silver lining, however. The small amount of traffic that does come through from AI surfaces appears to be substantially more valuable. Industry data indicates AI-referred visitors convert at up to 23x higher rates than traditional organic traffic, with 27% lower bounce rates and longer session durations. The volume is lower, but the quality is significantly higher.
What Experts Are Saying
The industry response to the STAT data has been a mix of alarm and strategic recalibration. Here is how leading practitioners are interpreting the findings.
“The future of our industry is not about optimizing for an engine, but about acting as the interface between businesses and technology.”
Haynes's framing captures the broader sentiment: AI Mode does not eliminate the need for SEO — it expands the scope. Practitioners who can bridge traditional optimization with AI visibility will be the most valuable.
“These aren't just a short version and long version of the same answer. They're two distinct systems that happen to converge on similar conclusions through different paths.”
The Ahrefs study underscored this point with a striking detail: despite the low citation overlap (13.7%), AI Mode and AI Overviews reach semantically similar conclusions 86% of the time. They agree on the answer — they just pick different sources to support it. This means the competition is not about having the right information, but about having it in the right format.
“AI-generated answers are highly unstable — 70% of pages included in AI Overviews change over just a few months. For enterprises, these changes represent an existential threat to discoverability.”
Ray's observation adds urgency: not only are you competing for different citation slots in AI Mode, but those slots are reshuffled frequently. Continuous monitoring is essential, not quarterly audits.
How to Optimize for Google AI Mode in 2026
With only 12% overlap between AI Mode and organic rankings, you cannot rely on your existing SEO strategy alone. Here are the practical steps to build visibility across both surfaces.
Step 1: Build Topical Authority, Not Just Page-Level Rankings
AI Mode favors sources that demonstrate comprehensive coverage of a subject. A single well-optimized page is not enough — you need a cluster of interlinked content that shows deep expertise across an entire topic area. Google's own documentation notes that its systems identify expertise “on a topic-by-topic basis,” meaning topical depth is evaluated at the site level.
Audit your existing content to identify topical gaps. If you rank for “keyword research tools” but have no content covering keyword difficulty, search intent, or long-tail strategy, you are leaving authority on the table. Use a tool like our free Related Keywords Generator to map out the full semantic landscape around your core topics.
Pro Tip
Internal linking is critical for topical authority. AI systems use link structure to understand content relationships. Make sure every piece of content in a topic cluster links to related pages with descriptive anchor text.
Step 2: Structure Content for AI Readability
The STAT study found that AI Mode results are nearly 99.5% text-based — paragraphs and lists dominate, with far fewer visual elements than traditional SERPs. This means AI Mode is selecting content that reads well as synthesized text, not content that performs well as a visual SERP listing.
Structure your content with clear heading hierarchies that match natural questions. Begin each section with a direct, citation-worthy statement before expanding with supporting detail. Use short paragraphs focused on a single idea. Make your content modular — each H2 section should be able to stand alone as a coherent answer.
To evaluate how well your content is structured, run it through our Helpful Content Checker to identify readability and quality issues before they cost you visibility.
Step 3: Strengthen E-E-A-T Signals
AI Mode cites Wikipedia 28.9% of the time (versus 18.1% for AI Overviews) and sources Quora at 3.5x the rate. The pattern is clear: AI Mode gravitates toward sources perceived as authoritative and trustworthy by design. For your own content, this means doubling down on experience, expertise, authoritativeness, and trustworthiness.
Practical steps include publishing content under named authors with demonstrable expertise, citing primary sources and original data, including dates and freshness signals, and earning mentions from authoritative third-party sites. Brand entity signals — being referenced across the web in relevant contexts — carry weight even when those mentions are not linked.
Step 4: Optimize for Entities and Brand Mentions
The Ahrefs study revealed that AI Mode responses include 2.5x more people and brand entity mentions than AI Overviews. And if your brand is mentioned in AI Overviews, there is a 61% chance it will also appear in AI Mode. Brand recognition is becoming a ranking factor.
Focus on building brand presence across the platforms AI systems draw from: publish expert commentary, participate in industry discussions, maintain consistent brand information across directories and knowledge bases, and ensure your structured data accurately represents your brand entity. Use our Technical SEO Audit to verify your schema markup and structured data are correctly implemented.
Pro Tip
AI Mode heavily favors conversational, question-answering content. Restructure your existing top-performing pages to lead with direct answers to common questions, then expand with depth. This positions your content for both featured snippets and AI citations.
Step 5: Adopt a Dual-Tracking Strategy
Since Google Search Console cannot yet distinguish between traffic from traditional results, AI Overviews, and AI Mode, you need additional monitoring. Use third-party rank tracking tools that specifically monitor AI Mode citations. Track brand mentions across AI surfaces, not just click-through URLs.
Shift your success metrics from purely click-based to visibility-based. As LinkedIn's AI Search Taskforce put it, the new framework is: “Be seen, be mentioned, be considered, be chosen.” You should measure share of voice in AI answers, citation frequency, and brand mention volume alongside traditional traffic metrics.
Don't chase AI Mode at the expense of fundamentals
76% of AI Overview citations still come from pages ranking in the top 10 organically. Strong traditional SEO is the foundation — AI Mode optimization layers on top of it. Neglecting organic fundamentals while chasing AI visibility is a losing strategy.

What to Expect Next
Google is actively expanding AI Mode's capabilities. Gemini 3, announced with enhanced reasoning and agentic coding abilities, is expected to further power AI Mode throughout 2026. Google has already introduced AI-powered calling to local businesses, agentic shopping with checkout capabilities, and Deep Search — a mode that issues hundreds of queries simultaneously to produce detailed research reports.
For advertisers, Google is now testing sponsored placements inside AI Mode, indicating this surface will become a commercial channel, not just an informational one. The 75 million daily user base is a strong enough foundation for Google to begin monetizing.
Gartner has predicted a 25% decline in traditional organic search volume by the end of 2026, and some forecasters project that 50% of all searches will be generative by 2028. Whether or not those exact numbers materialize, the direction is clear: conversational, AI-driven search is growing, and its ranking logic diverges sharply from what SEOs have optimized for over the past two decades.
The brands that start building dual strategies now — maintaining organic fundamentals while layering on AI-specific optimization — will be the ones best positioned as this transition accelerates.
Frequently Asked Questions
Key Takeaways
The STAT study's 12% overlap finding is a line in the sand. Google AI Mode is not a cosmetic change to search — it is a structurally different ranking surface that selects sources through different criteria, rewards different content properties, and serves a growing base of 75 million daily users. SEO professionals who treat it as “just another SERP feature” risk losing visibility in the fastest-growing segment of Google Search.
Your Action Plan:
- Audit your content for topical completeness — fill gaps that weaken your authority in AI systems
- Restructure key pages for AI readability — lead with direct answers, use clear heading hierarchies, keep paragraphs modular
- Strengthen E-E-A-T and entity signals — named authors, primary sources, structured data, and brand mentions across the web
- Set up dual tracking for organic rankings and AI Mode citations — measure visibility, not just clicks
- Don't abandon organic fundamentals — they remain the foundation that AI systems build on
The search landscape is splitting into two parallel surfaces with different rules. The good news is that many of the principles — authoritative content, strong E-E-A-T, topical depth — overlap between both. Start by strengthening those shared foundations, then layer on the AI-specific optimizations. Explore our free SEO tools to audit your current positioning and identify your biggest opportunities.
