Google AI Overviews — the AI-generated answer summaries displayed above traditional search results — are now active in over 120 countries (Google I/O, May 2025). For digital marketing, this means the rules of visibility are changing fundamentally. This guide covers everything you need to know about AI Overviews: when they appear, how Google selects sources, and concrete strategies for getting included.
What Google AI Overviews are and when they appear
Google AI Overviews are AI-generated summaries that appear at the top of Google search results for selected queries. They synthesize information from multiple sources and present a coherent answer, often with links to the sources used. The feature was launched as "Search Generative Experience" in 2023 and renamed to AI Overviews in 2024.
AI Overviews do not appear for all queries. Data from SE Ranking (2025) shows they are triggered for approximately 15 to 25 percent of searches, depending on market and category. Informational queries with complex questions trigger them most often, while navigational queries (where the user wants a specific page) and simple fact queries rarely trigger AI Overviews.
Query types that consistently trigger AI Overviews include comparison questions ("difference between X and Y"), process questions ("how to do X"), evaluation questions ("is X good for Y"), and compound questions with multiple dimensions. For non-English markets, coverage is somewhat lower but increasing rapidly through 2026.
How Google selects sources for AI Overviews
Google's source selection for AI Overviews is closely related to, but not identical with, organic ranking. Studies from Authoritas (2025) show that 85 percent of sources cited in AI Overviews already rank on page 1 in organic results for the relevant query. However, it is not necessarily the top-ranking results that are selected.
Google prioritizes sources that provide precise, fact-based answers with clear structure. Pages presenting information in lists, tables, or clear paragraphs with definitions have higher citation rates than pages with running text without clear organization. Source diversity is also a factor — Google prefers to pull from multiple different sources rather than basing the entire AI Overview on one source.
E-E-A-T signals (Experience, Expertise, Authoritativeness, Trustworthiness) play an amplified role for AI Overview inclusion. Pages with named expert authors, clear publication dates, visible sources, and documented expertise are selected more often. For YMYL topics (Your Money Your Life), these requirements are even stricter. Our guide to entity SEO and Knowledge Graph explains how to build your brand as a recognized entity Google trusts. For structured data reinforcing E-E-A-T, see our schema markup guide.
The relationship between organic rankings and AI Overview inclusion
There is a clear correlation between organic ranking and AI Overview inclusion, but the relationship is not linear. You do not need to rank number 1 to be included — data shows that sources from positions 3 through 7 are regularly included. But you typically need to be on page 1.
A study by Semrush (2025) of 100,000 AI Overviews found that 62 percent of cited sources ranked in the organic top 5, 23 percent ranked in positions 6 through 10, and 15 percent ranked outside the top 10. The last category consisted primarily of highly authoritative sources such as Wikipedia, government institutions, and established industry sites.
For businesses, this means that a strong SEO strategy is a necessary but not sufficient foundation for AI Overview visibility. You must combine solid ranking with content structure optimized for AI extraction. Read our complete guide to search engine optimization for foundational ranking strategy.

Content formatting for AI Overview citation
The formatting of your content has a direct impact on whether Google chooses to include it in AI Overviews. Based on analysis of thousands of AI Overviews, we have identified clear patterns in what type of content gets selected.
Google frequently pulls from paragraphs that begin with a clear definition or concrete answer. Formulations like "X is Y that does Z" or "The three most important factors are A, B, and C" are typical citation patterns. Avoid burying the answer — place it in the first sentences under relevant headings.
- Use question-and-answer format in headings where natural
- Start paragraphs with concise definitions or concrete answers
- Structure comparisons in tables or bulleted lists
- Include summary paragraphs with key findings per section
- Use numbered lists for step-by-step processes
- Mark up content with FAQPage and HowTo schema where relevant
How to track AI Overview appearances
Tracking AI Overview visibility requires a combination of Google Search Console data and third-party tools. Google Search Console does not currently show directly whether you are included in AI Overviews, but there are indicators and tools that provide valuable insight.
Google Search Console can provide indirect data through changes in impressions and CTR for specific keywords. If a keyword suddenly receives significantly more impressions but lower CTR, it may indicate that an AI Overview now appears for that query. Read our GSC guide for more on interpreting these data patterns.
Third-party tools such as Semrush, Ahrefs, and SE Ranking have all implemented AI Overview tracking. These tools identify which keywords trigger AI Overviews and whether your site is included as a source. For dedicated GEO tracking, tools like Otterly.ai and Profound offer more granular insight into AI citation patterns.
Impact on organic CTR
AI Overviews have documented impact on organic CTR, but the picture is more nuanced than many fear. A study from Datos/Semrush (2025) showed that queries with AI Overviews had 8 to 12 percent lower aggregate CTR to organic results compared to queries without. However, the distribution is uneven.
Pages cited in the AI Overview often experience increased CTR compared to their organic position alone. Users who want to read more click on the cited sources. Pages that are not cited experience greater CTR loss because the user already has the answer and has less reason to scroll past the AI Overview.
For commercial and transactional queries, the CTR impact is less dramatic. Users who want to buy something still need to visit websites to complete transactions. It is for informational queries — where the answer can be consumed directly in the AI Overview — that CTR loss is greatest. The strategy should therefore be to secure citation rather than worry about CTR loss. At LeapJet, we see that clients who actively optimize for AI Overview inclusion compensate for CTR loss with increased visibility and brand exposure.

Opt-out considerations: x-robots-tag noai
Google offers the option to exclude your content from AI Overviews using x-robots-tag with the noai directive, or Google-Extended in robots.txt. But should you use it? In the vast majority of cases, the answer is no.
Blocking AI Overviews means giving up visibility in the fastest-growing part of search results. Your competitors will fill the space you leave behind. There are exceptions — for example, media companies with paywalls that do not want their content summarized for free — but for most businesses, inclusion in AI Overviews is an advantage, not a disadvantage.
Consider opt-out only if you have documented evidence that AI Overviews reduce traffic and conversions for key content behind a paywall, or if your content is being misrepresented in AI summaries. In all other cases, the strategy should be to optimize for inclusion and citation.
Strategies to appear in the AI Overview carousel
The AI Overview carousel is the horizontal list of sources displayed at the bottom of the AI Overview box. Being included here provides visible brand exposure and clicks, even if your content is not directly cited in the answer text itself.
To increase your chances of carousel inclusion, ensure that your page has an attractive and correct Open Graph image, a precise meta description, and a title tag that clearly communicates the content's value. Google uses these elements to display carousel cards.
Publish content that covers the topic from a unique angle. If all competitors write general overviews, write a specific case study with data. If everyone writes case studies, create a comparative overview. Diversity in the carousel is a pattern we see repeatedly — Google includes sources that complement each other, not just those that are most similar.
Preparing for AI Overviews in non-English markets
AI Overviews for non-English queries are still in an early phase compared to English-language search. Coverage is lower, and answer quality varies more. This represents an opportunity for businesses in smaller language markets who act now.
For queries that trigger AI Overviews in non-English languages, competition for citation is significantly lower than in English. This means that well-structured native-language content has a relatively higher chance of inclusion. Prioritize producing in-depth content in your primary language for core topics — many businesses still publish primarily in English, leaving a gap in native-language AI Overview coverage.
Remember that Google can also show AI Overviews based on English-language sources for non-English queries, especially for technical and professional topics. A bilingual content strategy — as we recommend in our GEO guide to generative engine optimization — therefore provides the broadest possible coverage. For a detailed walkthrough of ChatGPT-specific optimization, see our guide to ChatGPT Search optimization. See also our glossary for definitions of terms like AI Overviews, featured snippets, and Knowledge Graph. Ensure that both language versions are indexed and interlinked with hreflang to maximize visibility in AI Overviews regardless of search language.
