In 2024, 58.5% of U.S. searches and 59.7% of E.U. searches ended without a single click, according to SparkToro’s 2024 zero-click study. For most queries, Google now answers the question on the results page, and the user never visits a website. That is the definition of zero-click search, and AI Overviews have turned it from a slow drift into the default.
If you sell online, this is a traffic problem with a face. The pages you spent years ranking are still ranking, but the clicks that used to follow the ranking are disappearing into an AI-generated summary at the top of the page. This guide explains what zero-click search is now, why Google AI Overviews are accelerating it, how much eCommerce traffic is actually at risk, and the answer engine optimization playbook for getting your brand into the answer instead of being buried beneath it.
Overview
- Zero-click search is when Google answers a query directly on the results page, so the searcher never clicks through to a website. In 2024, it accounted for roughly 58-60% of Google searches (SparkToro).
- AI Overviews, Google’s AI-generated summary box, became the productized name in May 2024 and now appears on a large and growing share of queries.
- For eCommerce, the risk is not lost rankings, it is lost clicks behind kept rankings. Pew Research found that link clicks fall from 15% to 8% when an AI summary is present.
🚀 Quick takeaway
Your rankings can hold steady while your clicks quietly collapse. Zero-click search breaks the old assumption that a top position equals traffic.
What is zero-click search?
Zero-click search is a Google search that ends on the results page, with the answer shown directly to the user without any clicks to any website. The information is available in a search feature, so the searcher’s need is met before a single blue link is clicked. These on-page answers can be:
- featured snippets and direct text answers
- AI Overviews, the AI-generated summary at the top of the page
- knowledge panels and instant facts
- local map packs and business listings
- product carousels pulled from Google’s Shopping Graph
In 2024, 58.5% of U.S. searches and 59.7% of E.U. searches ended without a click, per SparkToro’s 2024 study with Datos. That figure has been climbing for years, and the arrival of AI-generated answers has pushed it higher. The old industry shorthand was “about half of searches are zero-click.” The honest 2024 number is closer to three in five.
🚀 Quick takeaway
Zero-click does not mean zero value. It means the value is captured inside the result, so the brand that gets quoted in the answer wins the visibility the click used to carry.
Why AI Overviews drive zero-click search
AI Overviews are the single biggest accelerant behind zero-click search, because they answer the whole query at the top of the page before the organic results even start. Instead of ten links, Google composes a summary from several sources and presents it as the headline result. The links still exist, but they sit below an answer that often makes clicking feel unnecessary.
A quick note on naming, since the terminology changed. Google first tested AI answers under the experimental label Search Generative Experience inside Search Labs. At Google I/O in May 2024 the company productized it and rebranded it as AI Overviews. If you read older coverage referencing SGE, it is describing the same feature under its retired name.
The expansion has been fast. Semrush data shows AI Overviews triggered for 6.49% of queries in January 2025 and 13.14% by March 2025, roughly doubling in a single quarter. Pew Research, analyzing real browsing behavior, found AI summaries appeared on around 18% of all Google searches it studied. The direction is one way, and it is up.
What makes AI Overviews different from a classic featured snippet is breadth. A snippet quotes one page. An overview synthesizes several, names a handful as sources, and answers follow-up intent in the same box. For a shopper researching a product, that can mean the comparison, the recommendation, and the reasoning all appear before they ever reach your product page.
🚀 Quick takeaway
AI Overviews are not a bigger featured snippet. They are a different layer that sits above organic results and absorbs the click for entire question categories at once.
What does zero-click search mean for eCommerce traffic?
In eCommerce, the measurable damage shows up as a drop in click-throughs, not a drop in rankings. Pew Research, in July 2025, studied 68,879 real Google searches and found that when an AI summary was present, users clicked a traditional result link only 8% of the time, compared with 15% when no summary appeared, a 47% drop. They clicked on a source cited inside the AI summary just 1% of the time. Sessions ended entirely 26% of the time when an AI summary was shown, against 16% without one.
Read those numbers as a merchant. Your category pages and buying guides can keep their positions, and your traffic can still fall by nearly half on any query Google decides to answer with a summary. The earlier projections of a “15 to 25% organic drop” were guesses. The Pew figure is measured behavior, and it is worse than the guess.
The product layer is shifting, too. When a shopper asks a buying question, Google increasingly returns a curated product view drawn from its Shopping Graph, which holds more than 35 billion product listings and counting. Whether your catalog appears in that view depends on your product data and structured markup, not on your homepage’s domain authority. This is the same surface where agentic commerce is heading, with AI assistants comparing and shortlisting products on the shopper’s behalf, raising the stakes for being machine-readable.
🚀 Quick takeaway
The question is no longer “am I ranking.” It is “when Google answers this query without me, does my brand still get named in the answer.”
How to adapt: the AEO playbook for zero-click search
Adapting to zero-click search means optimizing to be the cited source inside the answer, which is the work of answer engine optimization rather than classic SEO alone. AEO restructures your content and data so AI Overviews and AI assistants can quote you cleanly. The practical moves break down like this:
- Answer the question in the first two sentences. Lead each page and section with a direct, 40 to 60-word answer, then elaborate. AI systems extract the clean answer, not the slow build-up.
- Add structured data. Mark up products, FAQs, how-tos, and reviews with schema so machines can parse facts without guessing. For product carousels, accurate, complete product data is what gets you into the Shopping Graph view.
- Publish first-party substance. Original data, real benchmarks, named results, and clear authority are what AI engines prefer to cite over thin, derivative pages.
- Cover the question cluster, not just the keyword. Map the follow-up questions a shopper asks and answer them on the page, because overviews reward sources that resolve the whole intent.
- Measure what AI engines say about you. Rankings no longer tell the full story. Start tracking brand mentions in LLMs so you can see whether ChatGPT, Perplexity, Gemini, and AI Overviews are naming you, and for which queries.
A boutique furniture brand worked with scandiweb to restructure its content and product data for AI search and broke into the top 3 AI answers for its core category, capturing visibility inside the answer that classic ranking alone would not have delivered. That is the outcome our AI search optimization work is built for, named in the answer, even when the click never happens.
🚀 Quick takeaway
SEO got you ranked. AEO gets you quoted. In a zero-click world, being quoted is what protects your visibility.
Should you still invest in SEO if searches are zero-click?
Yes, because zero-click and AEO build on SEO, they do not replace it. AI Overviews draw from pages that already rank well and carry topical authority, so strong technical search engine optimization remains the foundation that makes your content eligible for citation in the first place. The shift is in emphasis, not abandonment: keep earning rankings, then add the answer-shaped structure and data that lets those ranked pages get pulled into AI answers. Treating SEO and AEO as one program, rather than swapping one for the other, keeps visibility intact through the transition.
How do you know if AI Overviews are taking your traffic?
Look for the specific pattern of stable impressions and falling clicks on informational and comparison queries. In Search Console, segment your queries and watch for terms where your average position holds but your click-through rate drops; those are the queries Google is likely answering with a summary. Pair that with AI visibility tracking to see whether your brand is being mentioned in the answers. If impressions are steady, clicks are sliding, and you are absent from the AI answer, you have your diagnosis and your priority list.
FAQ
What is zero-click search?
Zero-click search is a Google search that provides answers directly on the results page, so the user gets what they need without clicking any links. In 2024, roughly 58-60% of Google searches ended this way, according to SparkToro.
Are AI Overviews and SGE the same thing?
Yes. Search Generative Experience (SGE) was the experimental name Google used in 2023 inside Search Labs. Google productized and rebranded the feature as AI Overviews at Google I/O in May 2024. AI Overviews is the current name.
How much eCommerce traffic do AI Overviews actually take?
Pew Research found that when an AI summary is present, users click a traditional result link only 8% of the time, compared with 15% without one, a drop of nearly 47%. Cited sources inside the summary are clicked just 1% of the time.
Does zero-click search mean SEO is dead?
No. AI Overviews pull from pages that already rank, so SEO still gets you eligible to be cited. The change is that ranking alone no longer guarantees a click, which is why answer engine optimization is added on top of SEO rather than replacing it.
What is answer engine optimization (AEO)?
AEO is the practice of structuring your content and data so that AI-driven search engines and assistants choose to cite your brand when they generate answers. It covers snippet-shaped answers, structured data, first-party content, and full question-cluster coverage.
How do I get my products into Google’s AI shopping results?
Accurate, complete, structured product data is the lever. Google’s Shopping Graph carries more than 35 billion product listings, and inclusion in AI-driven product views depends on machine-readable product information and schema, not on homepage authority alone.
How do I measure whether AI engines mention my brand?
Track brand mentions across AI answer engines like ChatGPT, Perplexity, Gemini, and Google AI Overviews, and pair that with Search Console data showing where impressions hold but clicks fall. Together, they tell you which queries you are losing to AI answers.
Protecting your organic visibility under AI Overviews starts with knowing exactly which queries are answering shoppers without you. If you want a clear read on where AI search is quoting your competitors instead of you, get an AEO audit and we will map which of your queries are slipping into zero-click answers, and what it takes to win the citation back.
