We are experiencing an enormous shift in how people find and consume content online. This trend began in 2007 with the introduction of Google’s Universal Search. This update replaced the traditional list of ten blue links with a more integrated experience that included images, videos, maps, news, and other content types, all within a single results page.
Artificial intelligence is now driving the next phase of this evolution.
Google’s relatively new AI Overviews move users toward a more streamlined, summary-based approach to information. Instead of relying on multiple clicks to gather details, users increasingly get direct answers within the search results. At the same time, those who do choose to click through tend to be more focused and intentional, often farther along in their decision-making process. This shift redefines the users’ initial search experience and their path toward conversion.
What are AI Overviews?
AI Overviews (AIOs) are a new search feature from Google that provides AI-generated answers to specific queries, typically appearing above all other search results. AI Overviews are supported by resource links to the content used to create the AI answer.
These AI-generated answers are created by gathering information from various sources across the web and include links to these sources for users who want more details. The goal is to enhance the search experience by offering quick, concise answers and reducing the need to visit multiple websites. AI Overviews are powered by Google’s Gemini language model and are designed to appear selectively, especially in response to complex queries that might typically require several searches to resolve.
Importance and Impact on SEO
AI Overviews are poised to reshape how users interact with search results, much like the shift brought on by featured snippets. By delivering quick, AI-generated answers directly within the search results, AIOs can increase the number of zero-click searches where users get what they need without clicking through to a website. This could impact organic traffic, especially for sites that appear below the AI-generated response.
At the same time, AIOs open the door to new visibility opportunities. When a site’s content is cited or featured in an AI Overview, it may boost exposure and click-through rate. Google’s early testing suggests that these overviews can drive more qualified traffic, as users who click are likely more engaged and genuinely interested in the topic.
Prevalence of AI Overviews
AI Overviews are becoming increasingly common in search results, with their presence growing rapidly across industries and devices. Data from Semrush Sensor in December 2024 showed that AIOs appeared in 6.71% of U.S. search queries, with higher rates in certain sectors—23.02% in Health and 20.13% in Science. By March 2025, research from seoClarity found that AIOs were showing up in 10.4% of desktop keyword searches in the U.S., marking a 31% spike during that month’s algorithm update and a staggering 156.7% increase since September 2024.
Mobile search has seen similar AIO momentum. AIO appearances on mobile jumped 119% in March 2025, nearly matching desktop visibility for the first time. Most AI Overviews are still tied to informational searches, accounting for about 88% of appearances, but their presence in transactional queries is growing, now at 8.9%. While rare, AIOs have also begun appearing in local search results, showing up in 0.14% of local keyword queries as of March 2025.
How AI Overviews Select Sources
There’s been a notable shift in how AI Overviews gather their information. Today, over 99% of AIOs source content from the top 10 organic search results—a sharp contrast to the early days of the Search Generative Experience, when citations had little connection to traditional rankings. Nearly 80% of AI Overviews now include a link to at least one of the top three search results, and almost half reference the top-ranking page directly.
This change directly responds to concerns about accuracy in earlier versions of AIOs. By leaning more heavily on trusted, high-ranking sources, Google is reinforcing the credibility of its AI responses. It also underscores one of Google’s most significant competitive advantages over standard large language models: its deep understanding of authoritative and relevant content within the broader web ecosystem.
Challenges with Acquiring Optimization Data
The combination of limited transparency from Google, technical barriers to tracking, and dynamic SERP behavior makes it difficult to reliably measure or analyze AIO visibility and impact.
Optimizing for AI Overviews
There are currently no official optimization strategies explicitly tailored for AI Overviews. According to Google, its systems automatically select which sources and links to include, meaning site owners can’t directly control whether their content appears in an AIO. Instead, the best approach is to follow Google’s broader search guidance, as outlined in Google Search Essentials.
- Start by ensuring that web pages can be found and understood. Ensure they are crawlable and indexable, resolving issues like blocked robots.txt files, noindex tags, 4XX errors, or a confusing site structure.
- Targeting long-tail keywords is important because AIOs are often triggered by more complex, nuanced queries.
- Creating high-quality content remains a cornerstone, particularly for sensitive topics in finance, health, or legal fields, where accuracy, originality, and expertise are held to higher standards.
- A strong user experience also plays a role, with factors such as page speed, mobile-friendliness, and secure connections (HTTPS) all contributing to visibility.
- Traditional on-page SEO tactics, such as optimized title tags, meta descriptions, clean URLs, well-structured headings, and natural keyword usage, continue to be valuable.
- Finally, backlinks still matter—earning links from reputable sites can help signal trustworthiness and boost a page’s chances of being featured.
