How Google's Ai Overviews with Gemini 2.5 Information changed worldwide: The answer to precise search queries
Google integrates advertising in AI tools-opportunities for everyone
With the expansion of its AI overviews to over 200 countries and more than 40 languages, Google has achieved an important milestone in the evolution of search engine technology. This comprehensive expansion, which was announced in May 2025, brings AI-generated search summary to over 1.5 billion users worldwide and changes fundamentally how people are looking for and finding information. At the same time, Google introduces strategic monetization measures by integrating advertisements directly into the AI overviews, which creates new opportunities and challenges for website operators and advertisers. The technology is driven by Google's most advanced language model Gemini 2.5, which has been specially optimized for search applications and provides significantly more precise and context -related answers.
Suitable for:
Worldwide availability and technological development
Comprehensive global expansion
The latest expansion of the AI Overviews is Google's largest international introduction of a search function. After the technology has already been available in over 100 countries in October 2024, it now reaches more than 200 countries and territories. This expansion includes newly added language support for Arabic, Chinese, Malay, Urdu and many other languages, which significantly improves accessibility.
In Europe, the introduction was gradually carried out, starting with test phases in March 2025 in Germany, Spain, Switzerland and Italy. Since the end of March 2025, AI overviews have been officially available in nine European countries: Austria, Belgium, Germany, Ireland, Italy, Poland, Portugal, Spain, Switzerland and the United Kingdom. It is important that the function in European countries is only accessible to users aged 18 and over and that registration with Google is necessary.
Technical innovation by Gemini 2.5
The quality of the AI Overviews was significantly improved by the integration of a specially adapted version of Gemini 2.5. This advanced language model enables Google to answer more complex questions and create more precise summaries. The technology uses a “query fan-out” technique, in which a search query is divided into several sub-topics and processed at the same time in order to provide more comprehensive and relevant results.
These technical improvements are reflected in the user experience: Google reports that AI overviews provide the fastest AI answers in the entire industry and maintain the usual speed of Google search. The extended skills enable users to ask more complex and multi -step questions that would have previously required several separate search queries.
Usage statistics and effects on search behavior
Significant increase in the frequency of searches
The introduction of the AI Overviews has led to measurable changes in user behavior. In the most important markets such as the USA and India, Google has an increase of over 10 percent for search queries that typically trigger AI overviews. This trend increases over time when users return more often after their first experience with AI OverViews and ask more complex questions.
User satisfaction is also evident in the quality of the interactions: users spend more time on target pages if they get there via AI Overviews compared to traditional search results. This indicates that the AI generated summaries act as quality filters and lead users to more relevant content.
Extended target group and accessibility
With the global expansion, AI overviews now reach over 1.5 billion users every month. Google has also expanded the availability for different user groups: the function is now available for young people and no longer requires registration. In addition, AI overviews are displayed in incognito mode, whereby the complete availability for non-registered users is mainly limited to the US market.
Suitable for:
Integration of advertising in AI Overviews
New monetization strategies
Google began integrating advertisements directly into AI overviews in May 2025, which represents a fundamental change in the monetization of search results. These shopping and search ads appear contextual within the AI generated answers and offer advertisers the opportunity to achieve users in early phases of their search for information.
The advertisement integration follows an “assistives” approach in which advertising is not positioned as a disruptive factor, but as a supplementary help along the customer journey. On a question of how "How do I found a company with little budget?" For example, contextual advertisements for website construction boxes could appear directly in the AI answer.
Technical implementation and availability
The new ad formats are initially available on desktop devices in the USA, with planned expansion to mobile devices and other English-language markets. Advertisers do not have to create separate campaigns, since the new placements are automatically activated for existing performance max, shopping or search campaigns with Broad Match.
In addition, Google is testing advertisements in AI Mode, an extended AI search function for complex inquiries. This development signals Google's intention of seamlessly integrating advertising into all AI-based search functions.
AI fashion: extended search functionalities
Introduction of AI Mode
With the AI Mode, Google introduced a new experimental search function, which was developed in response to the demand for power users for more comprehensive AI seek experiences. AI MODE offers extended recourse, thinking and multimodal skills and enables users to ask even more complex questions and to penetrate them deeper through follow-up questions.
This function uses the same query fan-out technique as AI overviews, but on a more advanced level. AI mode can carry out hundreds of search queries at the same time, analyze various sources of information and create comprehensive, fully cited reports in a few minutes that would normally require hours of research.
Future -oriented functions
The AI Mode serves as a test environment for Google's latest AI functions before they are integrated into the main experience. The announced extensions include Deep Search for even more thorough research, live functions for real-time camerageractions and personalized context integration from other Google services such as Gmail.
The personalization functions enable AI Mode to take past search queries and information from connected Google apps in order to provide tailor-made recommendations. Users keep full control over these integrations and can activate or deactivate them at any time.
Effects on SEO and content marketing
New opportunities through expanded source selection
Contrary to the widespread fear that AI overviews only fall back on the top 10 search results, Google actually uses an expanded circle of sources for the grounding of AI answers. This practice opens up additional opportunities for websites to be quoted in the AI overviews, even if they are not in the traditional top rankings.
The query fan-out technology enables Google to display a wider and more diverse selection of helpful links than with conventional websites, which creates new options for discovering content. This development means that high -quality, relevant content can also attain visibility if they are not one of the top search results.
Best practice for optimization
In order to improve visibility in AI overviews, website operators must adapt their content strategies. Central success factors include the creation of high -quality, relevant and comprehensive content, which answer user questions precisely and structured. Google prefers the use of a clear, concise language with a logical structure and meaningful headings.
Structured data (Scheme Markup) play an important role in optimizing AI overviews. The implementation of relevant schema types such as FAQPAGE, Howto, Article and Product helps Google to better understand the context and the relevance of content. In addition, the signaling of authority and trustworthiness through detailed authors' profiles, expertise proof and the structure of strong backlink profiles is crucial.
Change of SEO metrics
The introduction of the AI Overviews leads to a fundamental change in the evaluation of the SEO success. Classic key figures such as clicks, rankings and traffic are supplemented by new metrics, which focus on visibility and brand presence. The concept of zero-click marketing is gaining in importance because established brands are preferred in AI answers, even if this does not lead to website visits directly.
Suitable for:
Brand structure 2.0: score with AI in the search results
Effects on website traffic
The integration of comprehensive answers directly into the search result pages the risk of reduced click numbers for websites. A lot of information is now answered directly on the search results page without users having to visit a website. This development requires website operators to realign their strategies to brand structure and authority instead of pure traffic generation.
At the same time, Google's data show that AI Overviews can actually lead to an increase in traffic through prominent webs and in-line links. The challenge is to create content that is relevant for both AI summary and valuable for further user interactions.
Adaptation of monitoring and tools
The monitoring of performance in AI overviews requires new approaches, since traditional SEO tools do not offer any specialized reports for AI traffic. Website operators have to develop new metrics in order to pursue and optimize their presence in AI overviews. The observation of competitive prices outside of classic search sources is becoming increasingly important.
Branding authority and structured data: key to digital visibility
The global expansion of the Google Ai Overviews to over 200 countries marks a turning point in the evolution of search engine technology. With over 1.5 billion monthly users and demonstrably increased user satisfaction, this technology is established as a central component of digital information procurement. The integration of advertisements into AI overviews opens up new monetarization options for Google and at the same time changes the rules of the game for advertisers and content manufacturers.
For website operators and SEO specialists, there is a need for a strategic realignment. While traditional rankings lose importance, factors such as content quality, structured data and brand authority gain importance. The extended selection of sources of the AI Overviews offers new opportunities for visibility, but requires an adaptation of content strategies and metrics.
The future of the search will be significantly shaped by the further development of AI Mode and the integration of advanced AI functions. Companies that adapt their strategies to these new circumstances at an early stage and optimize both organic and paid presence in AI-based search results will be successful in the changed digital landscape.
