TL;DR — Between 60% and 68% of Google searches in 2026 end without a single click to a website. Google's AI Overviews now appear in 48% of queries and slash organic CTR by 61%. Gartner predicts a 25% drop in search engine traffic by the end of 2026. But panic is unwarranted: the strategy is changing, not dying. SMEs that adapt — optimizing to be cited by AI, not just indexed — can turn this disruption into a competitive advantage. In this article, we explain how, with data, real-world cases, and an actionable checklist.
The Silent Crisis: When Google Stops Sending Traffic
There is one number that should keep every entrepreneur and marketing manager awake at night: 58.5% of Google searches in the United States and 59.7% in Europe end without the user clicking on any result (Datos/SparkToro, State of Search Q2 2025). The user searches, reads the answer directly in the SERP, and leaves. Zero clicks. Zero visits to your website.
This is not an anomaly. It is a structural trend that is accelerating quarter after quarter. By mid-2025, zero-click searches had already surpassed 65% of the total. And with the aggressive expansion of AI Overviews — AI-generated summaries that Google places at the top of the results page — the phenomenon is reaching levels that just two years ago would have seemed dystopian.
As we at Deep Marketing keep telling our clients: it is not a question of "if" your organic traffic will decline, but of how much and what you will do to compensate.
The Numbers Nobody Can Ignore: The CTR Collapse with AI Overviews
The most rigorous study available on this topic is from Seer Interactive (September 2025), which analyzed 3,119 informational queries across 42 organizations, covering 25.1 million organic impressions and 1.1 million paid impressions over 15 continuous months (June 2024 – September 2025).
The results are devastating:
In plain terms: when Google shows an AI Overview, only 6 out of 1,000 users click on an organic result. And the situation is not temporary — Seer tracked the trend over 15 months, confirming that CTR has stabilized at these low levels with no signs of recovery.
But there is one data point that illuminates the way out: brands cited within AI Overviews achieve 35% higher organic CTR and 91% higher paid CTR compared to brands that are not cited. Being inside the AI summary is not just a defense: it is a multiplier.
How Widespread Are AI Overviews? More Than You Think
According to BrightEdge (February 2025 – February 2026) data, AI Overviews have grown 58% in one year and now appear in 48% of all searches. No longer a fringe experiment: they are the new normal of the SERP.
And the growth is not uniform. Some industries have been literally overwhelmed:
Industries with heavy informational content — healthcare, education, B2B tech — are the hardest hit. Transactional industries (e-commerce, retail) hold up better: only 10% of commercial keywords trigger an AI Overview, because Google knows that when a user wants to buy, they still need to click.
For SMEs, this means that those operating in services, consulting, training, or B2B are in the maximum impact zone.
Gartner's Prophecy: −25% Traffic by the End of 2026
In February 2024, Gartner predicted that search engine volume would drop by 25% by 2026, due to AI chatbots and virtual agents. Two years later, market data is confirming the direction — even if the exact number remains debated.
What is no longer debated is the mechanism: generative AI solutions are becoming substitute answer engines. Users are not asking fewer questions — they simply no longer search for answers by clicking on traditional "blue links." They use ChatGPT, Perplexity, Claude, Gemini, or read Google's AI Overview without going further.
Bain & Company also confirms the trend: 80% of consumers rely on zero-click results at least 40% of the time, and overall organic traffic is declining between 15% and 25%. Bain identifies two converging tectonic forces: AI summaries from traditional search engines (Google AI Overviews, Bing Copilot) and the rise of LLMs as standalone search engines (Perplexity, ChatGPT Search).
The Paradox: More Searches, Fewer Clicks
One aspect often overlooked in the debate is that total search volume is not declining — it is growing. BrightEdge recorded a 49% increase in total search impressions over the past year. Users are searching more, but clicking less.
For the broader market, this paradox has specific implications. Google holds roughly 92% of the global search market. AI Overviews have been extended to most markets throughout 2025, and their presence in search queries is constantly growing.
SMEs that have historically invested little in SEO risk a double disadvantage: they have less baseline domain authority and fewer structured contents to be cited by AI. Those who do not adapt risk becoming invisible not in years, but in months.
Why Panic Is Wrong (But Inertia Is Lethal)
Before rushing to dismantle your editorial plan, let us pause for a moment. The data also tells another story:
- Brands cited in AI Overviews gain 35% more organic clicks — being in the AI summary is an advantage, not a death sentence.
- Sessions from AI referrals grew 527% year over year in the first five months of 2025 (Previsible AI Traffic Report). This is a new traffic channel, not the end of traffic.
- Only 16% of brands systematically track their AI search performance — which means 84% of your competitors are asleep. This is a huge competitive opportunity.
- Transactional queries (those that drive sales) are the least affected — only 10% trigger an AI Overview.
The message is clear: traditional SEO is not dead, but it is evolving. Those who adapt now — while most competitors are paralyzed between panic and denial — will seize positions that will be extremely difficult to recover later.
Welcome to GEO: Generative Engine Optimization
If traditional SEO aims to get you to appear on the results page, GEO (Generative Engine Optimization) aims to get you cited in AI-generated responses. It is a new discipline, but with principles already codified by academic research and market data.
The fundamental difference? SEO positions you in a list. GEO places you in an answer. And a citation in an AI response carries enormous psychological weight: the user perceives your brand as an authoritative source selected by artificial intelligence.
According to Search Engine Land, the most effective GEO strategies fall into three categories:
- Semantic footprint expansion — covering a topic exhaustively, not superficially
- Factual density — inserting data, statistics, and citations every 150-200 words
- Structured data — schema markup, FAQs, tables, machine-readable formats
Each AI platform has its preferences: ChatGPT favors encyclopedic content, Perplexity rewards freshness and concrete examples, Google AI Overviews prioritizes content already well-ranked in the traditional SERP. But they all share one golden rule: clarity beats creativity. AI extracts self-contained passages of 134-167 words. If your content does not directly and completely answer a question within that space, it simply will not be cited.
How to Optimize for AI Search: The SME Checklist
Here are the concrete actions we at Deep Marketing implement for our clients — and that every SME should adopt immediately:
1. Restructure every piece of content with "citation blocks"
Start each section with a direct answer of 40-60 words that can be extracted standalone by AI. This is your "citation block" — the passage the AI can pick up and insert into its summary. Content with a semantic completeness score above 8.5/10 is 4.2 times more likely to be cited.
2. Increase factual density
Insert a data point, statistic, or verifiable citation every 150-200 words. Content with original statistics sees 30-40% higher visibility in AI responses. Do not fabricate numbers: citing authoritative sources strengthens both your E-E-A-T and the likelihood that AI considers you reliable.
3. Implement advanced schema markup
FAQPage, HowTo, Product, Author, Organization: every applicable schema increases the comprehensibility of your content for AI systems. Content with structured formatting (headings, bullet points, tables) is 28-40% more likely to be cited.
4. Build real authorship
Pages with identifiable expert authors are 3.2 times more likely to be cited in AI Overviews compared to generic "editorial" content. Create author bios with verifiable credentials, link them to your "About Us" pages and professional profiles.
5. Optimize for conversational queries
AI Overviews are designed to answer questions in natural language. Structure your content around real questions your customers ask. Use Google Search Console data ("Queries") and tools like AlsoAsked to identify the exact questions.
6. Diversify content formats
Videos, infographics, interactive content: Bain & Company explicitly recommends diversifying formats to increase visibility in generative AI search. A well-optimized YouTube video can be cited just as much as a written article.
7. Make your brand "entity-consistent"
Your brand description on LinkedIn, Crunchbase, Google Business Profile, industry directories, and your website must be consistent. When signals are aligned across sources, AI systems categorize and cite your brand with greater confidence.
8. Measure your Share of Model (SoM)
The key GEO metric is Share of Model: how often your brand appears in AI responses compared to competitors for relevant queries. Tools like Profound, Otterly.ai, and BrightEdge allow you to track it. If you are not measuring it, you are flying blind.
9. Do not abandon traditional SEO
Paradoxically, GEO strengthens classic SEO, it does not replace it. Google AI Overviews prioritizes content already well-ranked in the SERP. Backlinks remain the #1 factor for achieving the positions from which AI draws citations. Investing in digital PR and quality link building is more important than ever.
10. Monitor unlinked mentions
Mentions of your brand without links (unlinked mentions) are a very strong authority signal for AI models, which recognize entities across the entire web. Monitor and increase your brand mentions in articles, forums, social media, and directories.
The SME Case: Where to Start When Resources Are Limited
We know the checklist above may seem daunting for an SME with limited budget and resources. The good news is you do not have to do everything simultaneously. Priority should be defined based on your industry and the type of queries that drive your business.
If you operate in B2B or professional services (the segment most affected by AI Overviews), start with points 1, 2, and 4: restructure key content with citation blocks, increase factual density, and build real authorship. These three actions alone can make the difference between being cited or being ignored by AI.
If you operate in retail or e-commerce, the pressure is lower because transactional queries are less affected. Focus on points 3 and 7: product schema markup and brand entity consistency across platforms.
If you operate in restaurants or tourism, industries with explosive AI Overview growth (+680% and +381% respectively), point 5 is crucial: optimize for conversational queries ("what is the best gluten-free restaurant in Milan?", "what to see in Florence in 3 days?").
The New Metric: No Longer Traffic, But AI Visibility
Rand Fishkin of SparkToro puts it bluntly: "In a zero-click world, traffic is a terrible goal". Every platform — Google, Facebook, LinkedIn, Reddit, YouTube, Instagram, and AI tools — will send less traffic in 2026 than in 2025.
This does not mean digital marketing is dead. It means the metrics need to change. Bain & Company recommends shifting from click-based metrics to metrics based on:
- Search impressions — how often your brand appears, even without clicks
- AI reach — in how many AI responses you are cited
- Share of Model — your share of AI citations compared to competitors
- Brand search volume — how many people search directly for your brand (the ultimate awareness signal)
The practical advice is: monitor your brand search volume in Google Search Console. If it is growing despite the decline in generic organic traffic, you are doing the right things. People know you, search for you by name, and AI cannot mediate a branded search.
Zero-Click Marketing: Creating Value Where People Are
SparkToro defines zero-click marketing as the practice of creating standalone value on platforms where people spend their time, instead of publishing previews and links hoping they will click. It means writing LinkedIn posts that are the resource, not a teaser to the blog. It means creating Instagram reels that solve the problem, not redirect to the website.
This philosophy is not anti-website. It is pragmatic. If 60%+ of searches generate no clicks, concentrating all efforts on "driving traffic to the site" is like investing 100% of the budget in a channel that is declining. Diversify: the website remains the foundation, but value must be distributed wherever your audience is.
Frequently Asked Questions (FAQ)
What exactly is a "zero-click" search?
A zero-click search is a query on Google (or another search engine) that ends without the user clicking on any result. The user finds the answer directly in the SERP — through a featured snippet, knowledge panel, AI Overview, or simply by reading the titles and descriptions of the results. According to Datos/SparkToro data from 2025, between 58.5% and 65% of searches are zero-click.
Are Google's AI Overviews available globally?
Yes. Google has extended AI Overviews to most global markets throughout 2025. Their presence in search queries is constantly growing and follows the global trend. BrightEdge data shows that at a global level, 48% of searches trigger an AI Overview.
Is traditional SEO dead?
No, but it is transforming. Traditional SEO remains the foundation: Google AI Overviews prioritizes content already well-ranked in the classic SERP. Backlinks remain the #1 ranking factor. What is changing is that ranking on the first page is no longer enough — you also need to optimize to be cited by AI. GEO (Generative Engine Optimization) complements SEO, it does not replace it.
Which industries are most affected by zero-click searches?
Industries with heavy informational content are the most impacted: Education (+361% in AI Overviews), B2B Tech (+128%), Healthcare, and restaurants (+680%). Transactional industries like retail and e-commerce are less affected, as only 10% of commercial keywords trigger an AI Overview. SMEs in B2B, professional services, and consulting are in the maximum impact zone.
How can I find out if my site is being cited in AI Overviews?
Tools like BrightEdge, Profound (tryprofound.com), and Otterly.ai allow you to monitor your presence in AI responses. Alternatively, you can perform manual checks by searching for your target keywords on Google and observing whether your brand appears in the AI Overviews. The key metric to track is "Share of Model" — your share of AI citations compared to competitors.
How long does it take to optimize a site for GEO?
Initial results can be seen in 4-8 weeks by restructuring existing content with citation blocks and increasing factual density. Building authority (authorship, backlinks, mentions) is a longer process, typically 3-6 months. The important thing is to start now: only 16% of brands are tracking their AI performance, which means those who move first have an enormous competitive advantage.
Should I stop investing in Google Ads?
No, but you need to recalibrate expectations. Paid CTR drops by 68% when an AI Overview is present. The smart strategy is to concentrate paid budget on transactional queries (less affected by AIOs) and reduce investment on informational queries, where the AI Overview captures most of the attention. In parallel, invest in GEO-optimized content that gets you cited for free.
Conclusion: Adapt or Become Invisible
The numbers leave no room for interpretation: 60-68% of Google searches in 2026 generate no clicks. AI Overviews appear in 48% of queries and slash organic CTR by 61%. Gartner predicts a 25% drop in traditional search volume. Bain confirms an organic traffic decline of 15% to 25%.
But the numbers also reveal an opportunity: brands cited in AI Overviews gain 35% more clicks. Sessions from AI referrals are growing 527% year over year. And 84% of your competitors are not yet monitoring their AI presence.
The future of search is not click-less — it is about more intentional clicks, toward brands that AI recognizes as authoritative. The question for every SME is not whether to adapt, but how quickly. At Deep Marketing, we work on these strategies every day with our clients: GEO is not the future, it is the present.
