AI Search Performance Metrics in 2025
New data reveals alarming engagement metrics across the ai search landscape in 2025, with significant shifts reshaping user behavior and economics. The numbers tell a compelling story of how AI features are fundamentally altering search dynamics.
CTR Drop: 34.5% Decline with AI Overviews
Fresh research from Ahrefs confirms what many SEO professionals have suspected - Google's AI Overviews are dramatically cannibalizing clicks to organic listings.
Position one rankings experienced a staggering 34.5% CTR reduction when AI Overviews appeared in search results [1]. This represents a collapse from 7.3% CTR in March 2024 to just 2.6% by March 2025 for top-ranking pages [2].
The impact varies significantly based on several factors. For keywords ranking outside the top three positions, the decline is even more severe, with CTRs plummeting 27.04% on average [3].
Furthermore, the combination of AI Overviews with Featured Snippets creates a perfect storm, resulting in a devastating 37.04% CTR decrease [3].
Non-branded, informational queries bear the brunt of these losses. Amsive's analysis of 700,000 keywords found a 19.98% CTR reduction specifically for non-branded terms [4].
GrowthSRC Media's research confirms this trend, showing position two results suffering an even steeper 39% year-over-year decline, with CTRs falling from 20.83% to 12.60% [5].
13.14% of Queries Trigger AI Overviews by March 2025
The prevalence of AI Overviews has exploded in recent months. By March 2025, 13.14% of all search queries triggered AI Overviews, more than doubling from 6.49% in January - a 102% surge in just two months [6]. Semrush's analysis of over 10 million keywords confirms this rapid expansion [7].
User behavior data from Pew Research Center reveals that 58% of U.S. adults encountered at least one Google search with an AI summary during March 2025 [1]. Notably, certain query types disproportionately trigger these AI features:
- 60% of questions beginning with "who," "what," "when," or "why"
- 36% of searches containing both a noun and verb
- 53% of queries with 10+ words [1]
In contrast, only 8% of one or two-word searches generated AI Overviews [1]. The data indicates Google is primarily deploying this feature on informational queries - in fact, 99.2% of the 300,000 keywords studied that triggered AI Overviews had informational intent [2].
Inference Cost Reduction: 280x Since 2022
The economics underpinning ai search have transformed dramatically. According to Stanford University's Institute for Human-Centered AI's 2025 AI Index Report, the inference cost for a system performing at GPT-3.5 level has plummeted by an astonishing 280-fold between November 2022 and October 2024 [8].
In concrete terms, this represents a collapse from $20.00 per million tokens to just $0.07 [8]. This massive cost reduction changes the ROI calculations for AI in search and related applications. Depending on specific tasks, large language model (LLM) prices have decreased between 9 and 900 times annually [8].
This cost efficiency revolution has enabled the widespread deployment of AI features across search interfaces, consequently accelerating user behavior shifts toward zero-click experiences.
Indeed, when encountering AI Overviews, users clicked traditional search result links in only 8% of visits, compared to 15% without summaries [9]. Even more telling, users clicked on links within the summaries themselves in a mere 1% of cases [1].
Generative AI Tools Reshaping Search Interfaces
Major tech platforms have aggressively evolved their search interfaces in 2025, integrating sophisticated generative AI capabilities that fundamentally alter how users discover information online. These tools now serve as comprehensive answer engines rather than mere gateways to web content.
Google AI Search: Gemini and SGE Integration
Google's Search Generative Experience (SGE) has now expanded beyond experimental status, powered by a custom-built Gemini model specifically optimized for search functions. This integration brings advanced capabilities including multi-step reasoning, planning, and multimodality directly into the search interface [10].
By May 2025, Google began rolling out AI Overviews to everyone in the United States, with projections to reach over a billion users globally by year-end [10]. The custom Gemini model doesn't merely scan for keywords; it comprehends intent, semantics, and context—rendering increasingly obsolete traditional SEO tactics[11].
Usage data confirms SGE's impact: users with access to AI Overviews search more frequently and report higher satisfaction levels [10]. Nevertheless, this transformation creates significant challenges for visibility. The feature fundamentally disrupts established organic ranking hierarchies by aggregating content into summaries that may not drive clicks to source sites [11].
Despite challenges from AI competitors, Google's dominance remains formidable—handling approximately 373 times more searches than ChatGPT in 2024 [1]. The search giant saw more than 5 trillion searches that year (approximately 14 billion daily), representing a remarkable 21.6% year-over-year increase [1].
Microsoft Copilot Search with GPT-4
Microsoft has thoroughly reimagined search through Copilot integration with its Bing platform. The system leverages OpenAI's GPT-4.5 models to deliver conversational search experiences [5]. Unlike traditional search, Copilot Search functions as a universal experience across Microsoft 365 applications and third-party data sources [12].
A defining characteristic of Copilot Search is its contextual nature—rather than merely matching keywords, it finds relevant content through natural language understanding [13]. The system taps into Microsoft Graph, which encompasses information on users, their activities, and organizational data they can access [12].
For enterprise users, Copilot preserves security and compliance boundaries while enhancing search relevance through advanced lexical and semantic understanding of Microsoft Graph data [12]. This creates more contextually precise information retrieval while respecting organizational boundaries.
Microsoft began rolling out Copilot Search in June 2025, incorporating "Deep Search" capabilities that use GPT-4 to optimize results for complex topics [14]. If a search phrase has multiple possible meanings, Deep Search presents alternatives and lets users select the most relevant interpretation [14].
ChatGPT Search Usage Share: 59% in 2025
Despite Google's overall dominance, ChatGPT has established itself as the clear leader within the AI search segment. According to a May 2025 survey, approximately 54% of U.S. respondents cited ChatGPT's ability to summarize complex topics as their primary reason for using it as a search engine [7]. Other significant factors included:
- Requiring fewer clicks than traditional search (33% of respondents)
- Less cluttered interface (29% of respondents) [7]
By late 2024, ChatGPT's website recorded over 3.7 billion global visits monthly, with roughly 0.5-0.6 billion originating from the United States [1]. However, its overall market impact remains relatively modest—even if 100% of ChatGPT's estimated 125 million daily prompts overlapped with Google searches, its share would still represent less than 1% of total search volume [1].
The combined AI search market share of all major players—including Perplexity, Claude, Copilot, and Gemini—remains under 2% of global search volume [1]. Nevertheless, ChatGPT leads decisively within this specialized segment, capturing 80.1% of the AI search market as of early 2025 [2].
Rise of Multimodal and Voice-Based Search
Advanced voice and image recognition capabilities have emerged as pivotal frontiers in ai search development throughout 2025, expanding interaction paradigms beyond traditional text inputs. As consumer electronics giants deploy increasingly sophisticated multimodal technologies, the boundaries between different search modalities continue to blur.
Gemini Pro and Imagen 2 on Galaxy Devices
Samsung's multi-year partnership with Google Cloud has positioned the Galaxy S24 series as the first smartphone lineup to deploy Google's Gemini Pro and Imagen 2 technologies via Vertex AI cloud integration [9]. This strategic alliance delivers multimodal capabilities that seamlessly understand, operate across, and combine different information types including text, code, images, and video [9].
The implementation enables sophisticated summarization features across Samsung-native applications including Notes, Voice Recorder, and Keyboard [9].
Likewise, Imagen 2 integration brings Google DeepMind's advanced text-to-image diffusion technology directly to consumer devices, enabling intuitive photo-editing capabilities within the Galaxy S24's Gallery app [15]. This represents a significant advancement in bringing cloud-based ai search intelligence to mobile platforms.
Voice Search Adoption: 153.5M Users in US by 2025
The voice search ecosystem has expanded dramatically, with approximately 153.5 million Americans projected to use voice assistants by 2025, marking a 2.5% increase from 2024 [16]. This growth builds upon an established trend—in 2024, voice assistant users had already reached 149.8 million, following a 2.5% increase from 2023 [16].
Alongside this trajectory, roughly 27% of mobile users now rely on voice search [17], essentially transforming how information is discovered and consumed. Approximately 1 in 5 people worldwide presently use voice search, with global voice assistant usage estimated at 8.4 billion users [16]. This adoption rate underscores a fundamental shift toward more natural, conversational search behaviors.
Smart Speaker Market: $19B Projected in 2025
The global smart speaker market is forecasted to reach USD 15.10 billion in 2025, positioning it for continued expansion to USD 29.13 billion by 2032 at a 9.8% CAGR [8]. Alternative projections suggest the market value could reach USD 15.92 billion in 2025 [18].
Regional distribution reveals North America's dominant position, holding approximately 40.77% market share in 2024 [8]. Europe follows with a 29% share, while Asia-Pacific represents about 24% of the global market [18]. Cognitive Market Research projects the APAC region will experience the fastest growth at 12.5% CAGR through 2033 [18].
Smart speakers have fundamentally altered search behaviors by enabling hands-free, conversational interactions that demand precise, instant answers from ai search engines [19]. These devices increasingly serve as central hubs for controlling smart home ecosystems, managing daily routines, and accessing personalized information through voice commands [8].
Retrieval-Augmented Generation (RAG) in Enterprise Search
Enterprises across sectors are rapidly adopting Retrieval-Augmented Generation (RAG) as the cornerstone technology for enhancing internal ai search capabilities throughout 2025. RAG seamlessly combines information retrieval with text generation, integrating external knowledge bases to retrieve real-time, relevant information before generating responses.
RAG for Internal Knowledge Discovery
RAG excels in knowledge-intensive tasks where traditional search falls short. By providing contextually rich responses through sophisticated retrieval algorithms, RAG identifies pertinent documents from disparate datasets [20]. This approach significantly reduces hallucinations while maintaining coherence in generated content. The technology offers transparent source attribution—citing references for retrieved information—thereby boosting trust levels in high-stakes domains [20].
A critical advantage for enterprises lies in RAG's cost efficiency. Organizations can leverage existing knowledge bases without extensive retraining of large language models, as data augments the input rather than requiring the model to learn from scratch [20]. Subsequently, this approach dramatically reduces development and maintenance costs while improving user productivity through streamlined access to contextual data.
Glean and Squirro for Enterprise AI Search
Leading the enterprise ai search market, Glean has deployed impressive RAG implementations connecting to over 100 business applications. The platform builds knowledge graphs mapping people, content, and relationships while personalizing search results [4]. Organizations implementing Glean report saving approximately 10 hours per user annually, with adoption rates reaching 93% within two years of deployment [3].
Correspondingly, Squirro has positioned itself as the first fully integrated GraphRAG provider, achieving 99% accuracy through its integration of enterprise taxonomy and knowledge graph management [21]. The platform delivers 20% more precise insights at half the cost of competing solutions [21]. Unlike conventional systems, Squirro excels in high-risk environments through deeply customizable knowledge graphs and workflows that improve automatically with use.
Microsoft 365 Copilot with SharePoint Integration
Microsoft has elevated enterprise search through Copilot's integration with SharePoint. The system enables AI-powered agents to streamline workflows directly within SharePoint sites, pages, and files [22]. Administrators can approve agents, set defaults, and manage permissions through content governance tools [23].
To this end, Microsoft launched Copilot agents in SharePoint public preview in October 2024, allowing users to create and share agents directly within the platform [24]. These agents reason over scoped SharePoint content to answer questions and summarize information while adhering to each user's permissions and organizational security policies.
Market Shifts and Competitive Dynamics
Investment capital continues flooding the ai search market in 2025, fueling intensifying competition among established giants and agile newcomers alike. The battle for market share has sparked unprecedented valuations and rapid feature deployment across platforms.
Perplexity AI Valuation: $9B in 2024
Perplexity AI's meteoric rise stands as perhaps the most telling indicator of investor confidence in alternative ai search engines. The company's valuation skyrocketed from $520 million in January 2024 to $9 billion by December following a $500 million funding round led by Institutional Venture Partners [25]. Throughout 2024, the company raised capital five times, with backing from notable investors including Jeff Bezos, NVIDIA, and Databricks [26].
The company's financial fundamentals appear equally impressive, with annual recurring revenue exceeding $150 million by mid-2025—quadrupling from approximately $35 million a year earlier [27]. Amid heightened competition, newer funding rounds have pushed valuations even higher, reaching $18 billion in July 2025 [28].
Smart Mode vs Perplexity
The competitive ai search landscape extends beyond Perplexity, though factual comparison data between platforms remains limited. Within this specialized segment, dominates with an estimated 80.1% market share ChatGPT[6]. Smaller players like Grok and Perplexity hold 2.6% and 1.5% respectively, while DeepSeek claims 6.5% [6].
Google's AI Overviews Reach 1.5B Monthly Users
Google's AI Overviews has rapidly scaled to 2 billion monthly users across 200 countries by Q2 2025, up from 1.5 billion in May [29]. This represents one of Google's most successful Search product launches in the past decade [30].
The feature drives "over 10% more queries globally for the types of queries that show them," according to Alphabet CEO Sundar Pichai [29]. Simultaneously, Google's dedicated AI Mode chat interface has attracted 100 million monthly active users in the US and India [31], further cementing Google's dominance despite growing competition.
