How Google SGE and AI Overviews are changing search results
The rise of AI Overviews
Google rolled out AI Overviews globally in 2024, a feature previously known as Search Generative Experience (SGE). For an increasing number of search queries, Google displays an AI-generated answer at the top of the results that combines information from multiple sources. This fundamentally changes the dynamics of search.
For website owners and marketers, this has major implications. The traditional position 1 in Google is no longer the most visible spot. The AI-generated answer now occupies that position, and only websites cited as sources in that answer gain visibility in this new reality. This is exactly why Answer Engine Optimization (AEO) has become so important.
How Google selects sources for AI Overviews
Google uses a complex system to determine which sources are included in AI Overviews. While the exact algorithm is not public, there are clear patterns in which websites get cited.
- Websites that already rank highly in organic results have a greater chance of being cited.
- Content with clear, direct answers to specific questions is more frequently included.
- Sources with strong E-E-A-T signals get priority: expertise, experience and authority weigh heavily.
- Structured data (Schema.org) helps Google assess the context and reliability of content.
- Current content with recent publication or modification dates is used more often for time-sensitive topics.
The impact on organic traffic
Studies show that AI Overviews significantly influence click-through rates to websites. For informational queries where the AI answer is complete, traffic to individual websites drops. This is the zero-click phenomenon in its most pronounced form.
However, there are also positive aspects. Websites cited in AI Overviews report higher click-through rates than websites that held the same position in the old situation. The "source" label in an AI Overview functions as a quality mark that gives users confidence to click through.
Real numbers: the traffic shift
Multiple studies show that websites cited in AI Overviews see up to 40% higher click-through rates compared to similar positions in traditional search results. At the same time, traffic drops by 20 to 60% for websites that are not cited, depending on the query. The message is clear: being cited is crucial.

Analysis of thousands of AI Overviews shows that on average 3 to 5 sources are cited per answer. The chance of being included is greatest for websites already in the top 10 for the relevant query.
Strategy for visibility in AI Overviews
To remain visible in this new search experience, you need to adapt your content strategy. Here are the key strategic adjustments you can make.
Optimize for specific questions
AI Overviews are most frequently shown for informational queries. Structure your content around specific questions your audience asks. Use H2 headings as questions and immediately follow with a concise, clear answer. Then expand with in-depth explanation.
Build topical authority
Google prefers sources that demonstrate extensive expertise on a topic. Do not write a single article about a broad subject, but build a cluster of related articles that together demonstrate deep knowledge. This strengthens your position as an authoritative source.
Invest in unique data and insights
AI models value original data, research and insights. Content containing unique statistics, case studies or proprietary analyses has a greater chance of being cited than content that regurgitates existing information.
Optimize your technical layer
The technical foundation of your website plays an important role in selection for AI Overviews. Ensure comprehensive Schema.org markup, good loading speed, a logical heading structure and readable content. These technical signals help Google process your content faster and more accurately.
Content formats that perform best
Not all content formats perform equally well in AI Overviews. Based on analysis of thousands of AI Overviews, we see clear patterns.
- Definition articles ("What is X?") are most frequently cited for informational queries.
- Comparison articles ("X versus Y") perform well for evaluative searches.
- Step-by-step guides are often cited for "how to" queries.
- List articles ("10 best ways to...") are included for overview queries.
- Articles with recent data and statistics perform better for time-sensitive topics.
Beyond Google: other AI search platforms
Google AI Overviews is just the beginning. Perplexity, Microsoft Copilot and ChatGPT with browsing functionality are alternative search platforms that each have their own way of selecting and citing sources. An effective AEO strategy accounts for all these platforms.
The good news is that the fundamental principles are the same: high-quality content, strong authority, solid technical implementation and structured data work across all platforms. By investing in this foundation, you are not dependent on a single platform.
Measuring and monitoring
To refine your strategy, it is essential to monitor your visibility in AI Overviews. Google Search Console now shows data about impressions and clicks from AI Overviews. Additionally, there are tools like Profound and Otterly.ai that measure your AI visibility across multiple platforms.
- Monitor your Google Search Console for AI Overview impressions and clicks.
- Track which of your pages are cited as sources in AI answers.
- Compare your traffic trends before and after the introduction of AI Overviews.
- Analyze for which queries AI Overviews are shown in your niche.
- Adjust your content based on the patterns you discover.
Key takeaways
- Google AI Overviews display AI-generated answers at the top of search results, making the traditional position 1 less relevant.
- Websites with strong E-E-A-T signals, structured data and high organic rankings have the greatest chance of being cited.
- Being cited in AI Overviews delivers up to 40% higher click-through rates, while not being cited leads to significant traffic loss.
- Definition articles, comparisons and step-by-step guides perform best as content formats.
- Monitor your visibility via Google Search Console and specialized AI visibility tools.
Frequently asked questions
For what percentage of searches do AI Overviews appear?
The percentage is growing rapidly. In 2026, AI Overviews appear for an estimated 20 to 40% of informational queries, depending on the language and topic. For commercial and navigational queries, the percentage is lower. Google is continuously expanding the functionality to more query types and languages.
Can I prevent my content from appearing in AI Overviews?
Yes, you can use the nosnippet meta tag or data-nosnippet HTML attribute to prevent Google from including your content in AI Overviews. However, keep in mind that this also affects your visibility in regular featured snippets. In most cases, it is better to be cited than to hide your content.
How do AI Overviews differ from featured snippets?
Featured snippets pull content from a single source and display it prominently at the top of search results. AI Overviews synthesize information from multiple sources into a new, coherent answer. AI Overviews are more extensive, cite more sources and try to provide a more complete answer than featured snippets.
Does AEO optimization also work for AI Overviews in other languages?
Yes, the principles are the same. Google is rolling out AI Overviews in more and more languages. The optimization strategies (structured data, E-E-A-T, content quality) are language-agnostic. Do make sure your Schema.org markup contains the correct language indication with the inLanguage field.
Are Google AI Overviews a threat to my website traffic?
It depends on your strategy. If you do not optimize your website for AI Overviews, then it is indeed a threat: you lose traffic to the zero-click phenomenon. If you do optimize your content and get cited, it can actually be an opportunity: the "source" label in AI Overviews generates high-quality traffic from users who are specifically interested in your content.
In the era of AI search, the question is not whether you are found, but whether you are cited.
