AI Overviews used to be a curiosity for informational queries. Someone asked “what is compound interest” and Google’s AI generated a tidy summary. Annoying for publishers, sure, but not threatening to revenue. That changed. Semrush’s analysis of millions of keywords reveals that commercial queries triggering AI Overviews surged from 8.7% to 42.9% between January and November 2025. Your buying-intent keywords, the ones that pay the bills, now compete with Google’s own AI-generated answers.
This is not a future problem. It is a right-now problem. If your business relies on organic traffic from commercial search queries, you need to understand the data and adjust immediately.
The Semrush Data: What Actually Happened
Semrush tracked AI Overviews (AIOs) across millions of keywords throughout 2025. The numbers tell a clear story, and it is not the one Google is telling advertisers.
AIO Prevalence: The Rise and Settle
AI Overviews appeared for 6.49% of keywords in January 2025. They peaked near 25% in July, then settled at 15.69% by November. Google pulled back on volume but dramatically changed the mix of query types that trigger AIOs.
The Commercial Explosion
Here is the critical shift that most SEOs missed:
- Informational AIO queries dropped from 91.3% of all AIOs to 57.1%
- Commercial AIO queries surged from 8.7% to 42.9%
- Navigational queries with AIOs jumped from 0.74% to 10.33%
Let that sink in. Informational queries, the ones where an AI summary is arguably useful and low-risk for Google, went from dominating AIOs to barely half. Meanwhile, commercial queries, where Google earns its money through ads and where businesses earn theirs through organic traffic, multiplied fivefold.
Industry Breakdown: Who Gets Hit Hardest
Semrush’s data shows AIOs are not distributed evenly across industries:
| Industry | AIO Trigger Rate |
|---|---|
| Science | 25.96% |
| Computers & Electronics | 17.92% |
| People & Society | 17.29% |
| Law & Government | 14.56% |
| Finance | 12.21% |
| Health | 11.44% |
If you operate in science, tech, or finance, more than one in ten of your target keywords now triggers an AI Overview that answers the query before the user ever reaches your site.
Why Google Shifted to Commercial Queries
Google did not accidentally start showing AI Overviews for “best CRM software” and “cheap car insurance near me.” This is a deliberate strategy with three drivers:
1. Ad Revenue Expansion
Google Search revenue hit $63.07 billion in Q4 2025, up 17% year-over-year. AI Mode queries run three times longer than traditional searches. Longer queries mean more ad inventory. More ad inventory means more revenue. Google Marketing Live 2025 introduced new ad formats specifically designed for AI Overviews and AI Mode. The commercial query shift is not a side effect. It is the business model.
2. User Behavior Change
900 million people now use AI tools weekly. They do not search anymore. They ask. And when they ask commercial questions like “which project management tool is best for small teams,” they expect a synthesized answer, not a list of ten blog posts to manually compare. Google is responding to behavior, not creating it.
3. Competitive Pressure from ChatGPT and Perplexity
ChatGPT referrals to publishers grew 25x year-over-year. Perplexity processes queries that average three times the length of Google searches. When users can ask ChatGPT “recommend a CRM for a 10-person startup” and get a detailed comparison, Google’s traditional blue links look archaic. AIOs on commercial queries are Google’s defensive move.
What This Means for Your Business
The implications are significant and specific.
Organic Traffic Declines Are Accelerating
Forbes research shows AI Overviews can cause 15-64% organic traffic decline depending on the vertical. Small businesses get hit hardest because they lack the paid advertising budgets to compensate. When your commercial keywords trigger AIOs, Google answers the query in the SERP. The user never clicks. Your traffic disappears.
CPCs Are Rising Simultaneously
As organic traffic falls, businesses shift to paid search to maintain visibility. Higher demand for the same ad inventory drives up CPCs. Google embeds ads directly in AI Overviews and AI Mode results, creating a closed loop: your organic traffic drops, your CPCs rise, and Google captures both ends.
The Zero-Click Tipping Point
Similarweb’s latest data shows zero-click searches reached 69% by May 2025, up from 56% before AI Overviews launched. Organic traffic to news publishers dropped from 2.3 billion to under 1.7 billion visits. That is a 26% traffic reduction for an entire industry. Commercial queries crossing into AIO territory means the same dynamic now applies to ecommerce, SaaS, finance, and every other revenue-generating vertical.
The GEO Response: What Actually Works
Traditional SEO is not equipped for this. Optimizing for clicks on commercial keywords presumes users will click. They will not. You need a generative engine optimization strategy that optimizes for citations, not clicks.
1. Optimize for AI Citation, Not Rankings
When an AI Overview answers a commercial query, it cites sources. Your goal is to be one of those sources. This requires:
- Entity-based content structure: AI engines understand entities, not keywords. Build content around clearly defined products, brands, and concepts using schema markup.
- Answer-first writing: Put your answer in the first two sentences. Semrush’s data shows AI engines extract leading sentences 73% of the time.
- Authoritative citations and data: AI engines weight content backed by verifiable data. Include specific numbers, sources, and original research.
2. Build Cross-Platform Visibility
The Machine Relations analysis of 5.5 million LLM responses found that Perplexity, ChatGPT, and Gemini share zero cited domains on 35-40% of queries. Each engine uses different source selection logic. Optimizing for Google alone is a structural mistake. You need visibility across all three.
This means publishing on multiple platforms, building entity authority through mentions across six or more domains, and ensuring your llms.txt file is properly configured so AI engines can structured-read your content.
3. Track Your AI Visibility Separately from SEO
Google Search Console does not tell you whether ChatGPT recommends your brand. Semrush does not track Perplexity citations. Traditional SEO dashboards are blind to the platforms where your customers are actually asking questions.
You need dedicated AI visibility tracking. Monitor which engines cite your brand, for which queries, and how often. Track citation trends over time. Measure share of model, which is the percentage of AI responses that mention your brand versus competitors.
The Semrush Data in Context
Let me connect this to the broader picture using data from multiple sources:
- Similarweb: Zero-click searches hit 69%. Organic traffic to publishers down 26% since AI Overviews launched.
- Semrush: Commercial AIO queries up 393%. Navigational AIOs up 1,296%.
- Yext: Analysis of 6.8 million citations across Gemini, ChatGPT, and Perplexity shows significant differences in source selection per platform.
- Fuel Online: 92% of brands are invisible in AI search results across all major platforms.
- Forbes: AI Overviews can cause 15-64% organic traffic decline by industry.
- Google: Search revenue $63B/quarter. AI Mode ads live. Queries 3x longer than traditional search.
The pattern is clear. Google is systematically expanding AI-generated answers into the query categories where businesses spend and earn the most money. Organic traffic declines. CPCs rise. Google captures the delta. Brands that do not adapt to AI citation strategies lose revenue they cannot afford to lose.
The 2026 Commercial GEO Playbook
Here is a concrete action plan based on the data:
Step 1: Audit Your Commercial Keywords for AIO Exposure
Pull your top 50 commercial keywords. Check how many now trigger AI Overviews. The Semrush data suggests 15-25% of them already do, depending on your industry.
Step 2: Check Your AI Citation Rate
For the keywords that trigger AIOs, are you cited as a source? If not, that traffic is going to competitors who optimized for AI visibility. Run a free audit at audit.searchless.ai to see your current AI visibility score.
Step 3: Restructure Content for Citation
Rewrite your commercial pages to lead with definitive answers. Add structured data. Include verifiable statistics. Create entity-rich content that AI engines can extract and cite.
Step 4: Build Multi-Platform Authority
Publish on platforms that AI engines trust. Get mentioned in the sources that ChatGPT, Perplexity, and Gemini already cite. The Cloudbeds hotel study found that 98% of AI-recommended hotels appear on YouTube and 95% appear on Reddit. Broad digital presence drives AI visibility.
Step 5: Monitor and Iterate Monthly
AI citation patterns change. The Search Atlas data shows citation volatility is high: sources cited this month may disappear next month. Monthly tracking is the minimum viable cadence.
FAQ
What percentage of commercial queries now trigger AI Overviews?
Semrush data shows 42.9% of AI Overviews appear for commercial queries, up from 8.7% in January 2025. This represents a 393% increase in just 10 months.
Which industries are most affected by AI Overviews?
Science (25.96%), Computers & Electronics (17.92%), People & Society (17.29%), Law & Government (14.56%), and Finance (12.21%) have the highest AIO trigger rates.
How much traffic can AI Overviews cause me to lose?
Forbes research shows losses ranging from 15% to 64% depending on your industry and how many of your keywords trigger AIOs. Commercial query keywords tend to lose more traffic because AI Overviews can fully answer comparison and recommendation queries.
Is traditional SEO still worth doing?
Yes, but as a baseline, not a strategy. SEO ensures your site is crawlable and technically sound. But SEO alone cannot solve the zero-click problem. You need GEO, optimizing for AI citations, as a parallel discipline. HubSpot and Datos now describe GEO as essential, not optional.
What is the difference between AI Overviews and AI Mode?
AI Overviews are the generated summaries that appear at the top of some Google search results. AI Mode is a full conversational search experience where users interact with Google’s AI directly. AI Mode has a 93% zero-click rate compared to roughly 43% for standard AI Overviews.
How do I get my brand cited in AI Overviews?
Focus on three things: entity authority (mentions across multiple authoritative domains), answer-first content structure (put your definitive answer in the first two sentences), and structured data (schema markup that AI engines can parse). Use audit.searchless.ai to check your current AI visibility.
Does blocking AI bots stop my content from being cited?
No. Research shows that blocking AI crawlers does not prevent citations. AI engines can cite content they discovered through secondary sources, user submissions, and training data. Blocking bots may actually reduce your citation potential by removing the primary discovery channel.
Bottom Line
Semrush’s data confirms what the searchless optimization community has been tracking for months: Google is aggressively expanding AI-generated answers into commercial query territory. Your buying-intent keywords, the ones that drive revenue, now compete with Google’s own AI summaries in more than four out of ten cases.
This is not theoretical. The traffic is disappearing now. The CPCs are rising now. The 92% brand invisibility rate in AI search is a current measurement, not a projection.
The brands that survive this shift are the ones that stop optimizing for clicks and start optimizing for citations. That is what searchless.ai does: track your AI visibility, identify citation gaps, and build the authority signals that make AI engines recommend you by name.
