Google AI Overviews: Why Zero-Click Searches Are on the Rise
The New Reality of Google Search
How AI Overviews work is changing the entire search landscape. These AI-driven summaries analyse top-ranking web content, synthesise information, and deliver instant answers directly in search results, often before a user clicks a single link.
Here's the quick breakdown:
- Google's Gemini models scan the search index for relevant, authoritative content.
- Information from multiple high-ranking pages is processed and synthesised.
- A summary appears at the top of the results with links to cited sources.
- Users get answers instantly, reducing the need to click through to websites.
If you've noticed your impressions climbing while clicks drop, you're not alone. This is the "crocodile mouth" pattern: the widening gap between search appearances and actual clicks.
Since May 2024, AI Overviews have become a permanent feature, evolving from the experimental Search Generative Experience (SGE). They are no longer opt-in; they are everywhere, demanding immediate attention from marketers.
The data is stark. Research shows AI Overviews can reduce click-through rates by roughly 34.5%, and some studies report that over half of all Google searches now result in zero clicks. This isn't a minor tweak; it's a fundamental shift in how search delivers value.

What Are Google AI Overviews and How Do They Work?
Google AI Overviews (AIOs) are AI-generated summaries appearing at the top of search results. They act like super-powered featured snippets, providing direct answers so users don't have to click away. This is a major change from the traditional list of links.
These overviews provide a snapshot of key information with links to dig deeper. Evolving from the opt-in Search Generative Experience (SGE), AIOs are now a core, permanent part of Google Search for users in Australia, New Zealand, the US, and Canada.
The Technology Behind How AI Overviews Work
At the heart of how AI Overviews work is Google's advanced generative AI, powered by its Gemini model. This Large Language Model (LLM) is integrated into Google's core ranking system. Instead of just using training data, it actively searches and synthesises content from the web in real-time.
Here’s how it functions:
- Information Synthesis: The model sifts through web pages to find the most authoritative information and combines it into a coherent summary.
- Web Content Analysis: AIOs analyse current web content, ensuring information is fresh and backed by diverse sources, unlike a standard chatbot.
- Real-time Results: By pulling from the live web, AIOs deliver dynamic, up-to-date answers.
This process allows Google to provide helpful overviews and links directly on the search results page.
Aligning Content for AI Overviews: Search Intent & Query Types
Understanding search intent is more critical than ever with AI Overviews. They don't appear randomly; they are triggered by specific queries. If your content doesn't match the user's intent, you won't be featured.
Research shows AI Overviews appear for informational queries 99.9% of the time. These are searches for answers, explanations, or guidance, like "how to register a business in Brisbane."
Even for commercial queries, AIOs play an indirect role. A customer researching a product will likely see an AI Overview first. Your content needs to be cited there to influence their journey early on.
| Query Type | Example | AI Overview Likelihood |
|---|---|---|
| Informational | "How to improve website speed" | Very High (99.9%) |
| Navigational | "RankingCo Brisbane" | Low |
| Commercial | "Best SEO services Brisbane" | Moderate |
| Transactional | "Buy domain name" | Low |
To get cited, your content must provide clear, authoritative answers to your audience's questions. For more on this, see our insights on ChatGPT And SEO: What AI-Generated Content Means For Search Rankings.
Optimising for Informational Queries
To make your content irresistible to AI Overviews, focus on structure and clarity.
- Create "How-To" Content: Directly answer common questions with step-by-step guides, tutorials, and explainers.
- Use a Q&A Format: A frequently asked questions section with direct answers makes it easy for AI to extract information.
- Use Clear Headings: Descriptive H2 and H3 headings act as signposts, helping AI understand the structure and key points of your page.
- Implement Schema Markup: Use structured data to tell search engines exactly what your page is about (e.g., a how-to guide, product, or event).
- Optimise Meta Tags: Make your meta titles and descriptions specific and direct.
- Structure Your Information: Use bullet points, numbered lists, and concise summaries. This "chunkable" content is easy for AI to pull into an overview.
The goal is to create genuinely helpful, well-structured content that answers real questions. Do this, and AI Overviews will be more likely to cite you as a source.
The "Great Decoupling": Analysing the Impact on SEO & User Behaviour
A strange pattern is emerging in search analytics: impressions are climbing while clicks are flatlining or dropping. Industry experts call this the "Great Decoupling."
This isn't a data blip; it's a fundamental shift in user behaviour, driven by how AI Overviews work . Historically, more impressions meant more clicks. That relationship is now broken. The visual result is the "crocodile mouth" pattern, where impressions rise like an upper jaw while clicks fall away like a lower jaw.
How AI Overviews Work to Change Click-Through Rates
The cause of this split is simple: AI Overviews satisfy user queries directly on the search results page.
When an AIO appears, it claims the prime real estate at the top, pushing traditional organic listings down. For many informational queries, the AI summary is enough, so users don't need to click through.
This leads to two things:
- Inflated Impressions: Your content can get an impression as a traditional listing and as a cited source in the overview, boosting impression counts without more clicks.
- Reduced Clicks: With answers provided upfront, users have less reason to visit your website.
The data is clear. Some reports show 59% of Google searches result in zero clicks , a figure that climbs to 77% on mobile . When an AI Overview is present, click-through rates to websites can drop by approximately 34.5% .
This trend became undeniable as Google increased the presence of AIOs by 116% during a recent Core update. More content was cited, but fewer users clicked.
Being cited in an AIO offers visibility and authority, but it doesn't guarantee the engaged traffic of a traditional top ranking. Users are getting answers without ever visiting your site.
Why E-E-A-T Is Your Best Bet for AI Overview Visibility
To gain visibility in AI Overviews, your best bet is focusing on credible, trustworthy content. E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness) is no longer a nice-to-have; it's an absolute necessity.
How AI Overviews work is by synthesising information from sources Google trusts. The AI prioritises content demonstrating real expertise from authoritative sources. For Brisbane businesses that have already invested in building a solid reputation, this is good news.
Google's AI models need to provide accurate answers, so they favour content with strong E-E-A-T signals. This is why established sources are cited more frequently than generic content, regardless of traditional ranking.
Actionable Steps to Boost Your E-E-A-T
To convince Google's AI to cite you, focus on building genuine credibility.
- Showcase Author Credentials: Attribute content to real experts with verifiable qualifications. Include detailed author bios highlighting experience, certifications, and affiliations.
- Demonstrate First-Hand Experience: Share specific case studies, practical examples, and personal anecdotes. An authentic voice reflecting real-world knowledge is what separates cited content from the rest.
- Build High-Quality Backlinks: Links from reputable websites signal authority. Earning editorial links from respected industry publications is a core part of our expert SEO services and a powerful trust signal for AI.
- Leverage User Reviews: Positive reviews on Google Business Profile and other platforms show that real people value your expertise. AI notices these third-party validations.
- Ensure Factual Accuracy and Freshness: Regularly audit and update your content. Outdated or incorrect information will quickly erode trust.
Focusing on these elements builds credibility with both users and search engines. To learn more, check out our guide on AI-Powered Marketing Magic: Automate, Optimise, and Dominate.
