AI Overviews Appear On 14% Of Shopping Queries in Google

ECommerce sites had a brief window of immunity from AI Overviews. That window has closed.

A study published this week by Jeff Oxford, analyzing 20.9 million shopping-related search results, found that Google AI Overviews now appear on 14% of shopping queries — up from 2.1% in November 2025. That's a 5.6x increase in four months. The trend began in early November 2025, visible in traffic pattern data from large eCommerce benchmarks including Walmart.com and Target.com, and has continued steadily since.

The practical implication is direct: Google is inserting AI-generated content above shopping results on a growing share of product searches. The clicks that used to flow to product listings are increasingly being absorbed by an AI summary that sits above them.

What the Data Actually Measures

The study's methodology is worth understanding because the numbers are specific. Oxford identified shopping keywords by filtering search results for those with a shopping box — either paid or organic. Using Ahrefs' keyword database, he identified 20,900,323 shopping keywords that matched that criterion, then filtered for those with an AI Overview. The result: 2,919,229 shopping queries with AI Overviews — 14% of the total.

The keyword examples are deliberately representative of real purchase intent: "weighted blanket," "mushroom coffee," "protein powder," "blue t-shirts." These are not informational queries or research-stage searches. They are queries from people who are actively considering a purchase. The fact that AI Overviews are appearing on this category of search — not just content and publisher queries — marks a meaningful shift in what eCommerce SEO has to account for.

Four months ago, the consensus in eCommerce SEO was that AI Overviews were primarily a content-site problem. Publishers and media companies were losing clicks to AI-generated summaries. Product searches were largely unaffected. The Ahrefs data from November 2025 supported that view: 2.1% was low enough to treat as noise. At 14% and growing at this rate, it is no longer noise.

How AI Overviews Change the Search Dynamic for eCommerce

Traditional eCommerce SEO operates on a relatively well-understood model. Rank in the top positions for high-intent product queries, capture organic clicks, and drive traffic to product and category pages. The Shopping box — whether paid or organic — has been a reliable mechanism for product discovery at the moment of purchase intent.

AI Overviews alter that model by inserting a new layer above the Shopping results. When a user searches for "protein powder" and encounters an AI Overview before reaching product listings, their behavior changes. Some will engage with the AI content, get a recommendation, and click through to a specific product — potentially bypassing the broader set of results where competing products would otherwise appear. Others will have their query resolved at the SERP level without clicking through at all.

The click impact varies by query type and how thoroughly the AI Overview addresses the user's intent. But the directional effect — reduced clicks to organic product listings for affected queries — is consistent with what has already been observed for content-heavy queries, where AI Overviews have been present longer.

For eCommerce sites that have invested heavily in organic search as a traffic channel, the 14% figure represents a meaningful portion of their keyword universe now operating under different rules than the ones their SEO strategy was built for.

The Paid Search Interaction

One variable the organic-focused analysis doesn't fully address is the relationship between AI Overviews and paid shopping results. Google's Shopping ads sit in a distinct position relative to organic listings, and the interaction between AI Overviews and paid placements is still being established.

What is becoming clear is that the queries where AI Overviews appear are not queries where organic visibility alone is a sufficient strategy. Brands that appear within AI Overview recommendations — through structured data, review signals, and the kinds of authority signals that influence AI-generated content — are operating in a different position than those competing purely on traditional organic ranking factors.

The study's conclusion is that AI SEO is no longer optional for eCommerce. The shift from 2.1% to 14% in four months is a rate of change that, if it continues even at a fraction of that pace, will make AI Overview presence a mainstream concern across product categories by mid-year.

What AI SEO Means in Practice for eCommerce

The distinction between traditional SEO and AI SEO for eCommerce is not yet fully codified, but the emerging picture involves several overlapping factors.

Structured data and schema markup remain foundational — AI systems that summarize product information rely on machine-readable data to generate accurate, attribute-specific recommendations. Review volume, recency, and sentiment are signals that influence both traditional Shopping results and AI-generated summaries. Product content that directly answers comparative and evaluative questions — "what's the best protein powder for muscle recovery," not just "protein powder" — is better positioned for inclusion in AI Overview responses than content optimized purely for transactional keyword density.

Brand authority signals — the kinds of trust indicators that make a product or retailer a credible source for AI recommendations — are becoming a more explicit factor in visibility. This aligns with the Trustpilot dynamic covered earlier this week: review data and structured trust signals are becoming infrastructure for AI-mediated commerce, not just social proof for human shoppers.

For marketing and eCommerce teams currently operating under traditional SEO assumptions, the 14% figure is a useful forcing function to review those assumptions. The affected queries are not edge cases — they are the core product search vocabulary that drives organic revenue.
