Zero-Click Search
Zero-Click Search
A search session that ends without the user clicking any result link — the search engine answers the query directly on the results page, so no external website receives a visit. For ecommerce, zero-click search means a potential customer researches a product, category, or brand inside Google's SERP — seeing AI-generated summaries, shopping carousels, reviews, and comparisons — without ever landing on a retailer's website.
Why it matters in ecommerce
Organic search has historically been the largest free acquisition channel for ecommerce sites. As zero-click rates rise — driven by AI Overviews, Knowledge Panels, shopping carousels, and Google AI Mode — the volume of search-driven visits that actually reach a retailer's PDP or category page is shrinking. This does not eliminate search intent; it relocates where that intent is resolved.
The critical ecommerce qualifier (Ahrefs, April 2025): 99.2% of keywords that trigger AI Overviews are informational, not transactional. Shopping/purchase-intent queries still send clicks at higher rates and AI Overviews appear on fewer than 5% of them. The near-term threat is concentrated in discovery and research phases of the funnel, not direct conversion queries.
The longer-term threat (commercetools, April 2026) is structural: Google Shopping, TikTok Shop, Instagram Checkout, and AI agents are evolving to enable full research-and-purchase within platforms, making a retailer's own website progressively optional for lower-consideration purchases.
How it works
Google retains users by answering queries with SERP features:
- AI Overviews — AI-generated summaries answering informational and research queries. Appeared on >20% of all Google searches (as-of early 2026, Ahrefs tracker cited by SparkToro June 2026).
- Shopping carousels — product listings with price, rating, and availability surfaced directly in results. Users can compare and shortlist without visiting PDPs.
- Knowledge panels and rich results — brand information, store details, review aggregations visible inline.
- Google AI Mode — conversational interface resolving multi-step queries entirely within Google. Zero-click rate: 93% (as-of September 2025, Semrush, cited by commercetools April 2026). Accounted for ~0.34% of searches in January–April 2026 (SparkToro + Similarweb), growing rapidly; Google stated at I/O 2026 that AI Mode surpassed 1 billion monthly users with query volume doubling quarterly.
- Answer recycling — Google keeps users searching within its own ecosystem. In 2024–2026, the share of searches leading to another Google search rose 7.2 percentage points (SparkToro + Similarweb, June 2026).

The Ahrefs April 2025 CTR reduction figure (34.5%) was materially updated to 58% by December 2025 — an 8-month window. Any specific CTR-reduction figure carries high staleness risk; the directional finding (AI Overviews reduce CTR significantly) is robust. SparkToro's July 2024 zero-click rate (58.5%) is superseded by the early 2026 figure (68.01%).
Salsify Q4 2025 consumer survey and Semrush September 2025 AI Mode data may be outdated given rapid market movement.
Contradictions recorded
Google's claim vs Ahrefs research on AI Overview CTR impact. Google (Sundar Pichai) has claimed that links cited in AI Overviews receive higher click-through rates than those same pages would receive as a traditional organic listing. Ahrefs (Ryan Law + Xibeijia Guan, April 2025 updated December 2025) directly contradicts this: their study of 300,000 keywords found AI Overviews reduce the top-ranking page's CTR by 34.5% (April 2025), growing to 58% (December 2025). Ahrefs notes that Google Search Console does not allow publishers to distinguish AI Overview-referred clicks from regular organic clicks — "It seems that Google doesn't want us to see the clickthrough rate for AI Overviews." Sources: [Google (Sundar Pichai, cited via Search Engine Land)]; Ahrefs
Zero-click rate figures conflict by source and methodology. Multiple figures circulate: 58.5% (SparkToro + Datos panel, July 2024), 60%+ (frequently cited round number, Bain, DEPT Agency), 68.01% (SparkToro + Similarweb, early 2026). SparkToro explicitly cautions that these figures "compare apples and oranges" — different clickstream panels, different time periods, different methodologies. The 68.01% figure for early 2026 is the most recent and most rigorously documented; historical comparisons should be treated as directional, not precise. Sources: SparkToro June 2026; SparkToro July 2024
Ecommerce exposure: "protected" vs "increasingly at risk." Ahrefs and search-focused sources argue ecommerce is relatively insulated: 99.2% of AI Overview-triggering queries are informational (not transactional), and users still need to visit sites to purchase. DEPT Agency and commercetools argue ecommerce faces increasing structural risk as Google Shopping, TikTok Shop, and AI agents evolve to complete the purchase journey inside platforms. Both can be true simultaneously: current impact on transactional ecommerce is limited; the trajectory is toward greater platform mediation over time.

Ecommerce funnel impact
Analysis from DEPT Agency (Maria Prokopowicz, August 2025, updated July 2026):
Top-of-funnel (Discovery): Visibility in discovery searches is increasingly owned by Google's SERP features. Shoppers asking natural-language product research questions ("what's a good concealer for sensitive skin?") receive curated AI answers without visiting any retailer's page. Brand's own content has less direct reach at this stage.
Middle-of-funnel (Consideration): Consideration is shaped by third-party content — reviews, forums, influencer mentions — that AI engines surface. Brands are evaluated through sources they do not control.
Bottom-of-funnel (Conversion): Clicks to a retailer's website are still the dominant purchase path for most categories. The "click" becomes the premium outcome rather than the default — and when it happens, the arriving visitor is typically higher-intent.
commercetools (April 2026) identifies two adjacent risks that extend beyond standard zero-click:
- Brand commoditisation: AI-generated side-by-side product comparisons optimise for price and availability, eroding brand differentiation.
- Data ownership loss: transactions completed inside Google Shopping, TikTok Shop, or Instagram Checkout mean customer profiles belong to the platform, not the retailer — weakening CRM, repeat-purchase, and loyalty capabilities.
What practitioners report
Kendra Scott case study (DEPT Agency, August 2025): Since mid-2024, Kendra Scott added 8,000 new pages — many AI-assisted — organised around use-case and thematic queries ("gifts under $50," "everyday hoops for sensitive ears") rather than product names. Result: 27% of these pages appear on Google's first page, accounting for 5% of annual web traffic. Practitioners note: this content investment scale is now the baseline for meaningful organic reach in a competitive category.
Cetaphil case study (DEPT Agency, August 2025): Launched a pilot targeting non-branded symptom queries ("how to get rid of dry flaky skin on face") with the explicit goal of appearing inside Google AI Overview summaries — not driving direct clicks. Created landing pages optimised for AI Overview triggers; expanded PR and influencer presence to generate credible third-party citations, since AI engines prefer high-authority external sources.
Rand Fishkin / SparkToro (June 2026): Recommends replacing web traffic as a primary digital marketing KPI. Suggests building a "correlation dashboard" measuring brand awareness signals across platforms. Core argument: "Your product feed, your review corpus, your brand data — these are now your most important commercial assets."
Adobe Digital Insights (Q2 2026): AI-sourced traffic to US retailers grew ~400% YoY in early 2026; these visitors convert ~42% better than non-AI traffic, with longer sessions and lower bounce rates. The implication: fewer visits may not mean fewer conversions if the quality of AI-referred visitors is materially higher.
Strategies for ecommerce
1. Product schema markup and structured data Make product data machine-readable so Google, ChatGPT, and other AI engines can surface it accurately. Required fields: name, image, offers (price with ISO-4217 currency code, availability). Place markup in initial HTML — not JavaScript-injected — for reliable crawl frequency on volatile data (price, stock). Sites with proper schema see 20–30% higher CTR via rich results (as-of March 2025, Google, Microsoft, and ChatGPT confirmed schema use for generative AI features). Sources: Loopo; Koanthic.
2. Optimise for AI Overview citation, not just ranking Sites cited in AI Overviews earn +35% more organic clicks and +91% more paid clicks vs. uncited sites for the same queries (Go Fish Digital, March 2026). Priority: create authoritative, well-structured content that AI engines can directly quote. See AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization).
3. Thematic and question-driven content Add pages organised around use-case queries, not just product names. Ecommerce SEO at the content scale now required is a significant investment (Kendra Scott: 8,000 pages).
4. First-party channel investment Build acquisition and retention channels that are not algorithmically dependent: email lists, loyalty programmes, SMS flows, owned communities. Even if discovery occurs on third-party platforms, retention should not. Sources: SparkToro (June 2026); commercetools (April 2026). See Zero-Party Data and First-Party Data.
5. Participate in platform-native commerce Active participation in Google Shopping, TikTok Shop, Instagram Checkout, and AI agent shopping integrations treats these platforms as a distribution expansion layer rather than a threat. At the same time, build resilience outside these platforms. Source: commercetools (April 2026).
6. Replace traffic-as-KPI Zero-click is structural, not a temporary dip. SparkToro argues traffic should be replaced as the primary digital marketing KPI with brand awareness signals measured across platforms. Source: SparkToro (June 2026).
