The Changing Landscape of Google Search
The digital publishing world is currently navigating one of the most significant shifts in the history of the open web. For decades, the relationship between Google and publishers was relatively symbiotic: publishers provided the content, and Google provided the audience through organic search results. However, the introduction and aggressive expansion of Google’s AI Overviews (AIO) has fundamentally altered this dynamic. According to a comprehensive new report from Define Media Group, the impact is no longer theoretical—it is measurable, and for many, it is stark.
The report reveals that organic search clicks have plummeted by 42% since the broader rollout of AI-generated summaries. This decline represents a massive redistribution of traffic that threatens traditional SEO strategies while simultaneously opening new, albeit different, doors for growth. As Google transforms from a “search engine” that directs users to websites into an “answer engine” that provides information directly on the results page, the industry is witnessing a pivot toward real-time reporting and feed-based discovery.
A Deep Dive into the Numbers: The 42% Decline
To understand the gravity of these findings, it is essential to look at the dataset provided by Define Media Group. The analysis drew from Google Search Console data across a diverse portfolio of 64 high-traffic websites. This wasn’t a small sample size; the baseline traffic for these sites was substantial, providing a clear window into how user behavior has changed since AI became the centerpiece of the search experience.
From the first quarter of 2023 through the first quarter of 2024, organic search traffic for this portfolio was stable, averaging approximately 1.7 billion clicks per quarter. This period serves as the “pre-AI” baseline. The disruption began almost immediately after the initial launch of AI Overviews. Upon the first implementation, search traffic saw an immediate 16% dip. Unlike previous algorithm updates where traffic might fluctuate and then stabilize, this traffic never recovered to its original levels.
The situation intensified in May 2025, when Google significantly expanded the footprint of AI Overviews. This expansion meant that more queries across a wider range of categories were being met with an AI-generated summary at the top of the page. By the fourth quarter of 2025, the cumulative loss was staggering: organic search clicks had dropped by a total of 42% compared to the pre-AI baseline. This trend suggests that as Google refines its AI, the “zero-click” search—where a user finds their answer without ever leaving Google—is becoming the new standard for informational queries.
The Polarization of Content: Evergreen vs. Breaking News
While the overall 42% drop is alarming, the report highlights that the pain is not being felt equally across all types of content. The data reveals a sharp polarization between “evergreen” or informational content and breaking news. Evergreen content, which includes how-to guides, definitions, and general information, has historically been the bread and butter of long-term SEO. Unfortunately, this is exactly the type of content that AI Overviews are best at summarizing.
When a user asks “How to change a tire” or “What is the capital of Kazakhstan,” the AI can provide a concise, accurate answer sourced from the web, removing the need for the user to click on a specific article. Consequently, publishers who rely heavily on “how-to” and general knowledge traffic are seeing their search referrals evaporate.
Conversely, the report found a remarkable surge in traffic for breaking news. From November 2024 through early 2026, breaking news traffic grew by 103%. This suggests that while Google is comfortable using AI to answer static questions, it is still leaning heavily on traditional publishers to provide real-time updates on developing stories. For the news industry, the “Top Stories” carousel remains a vital lifeline, often appearing in place of, or more prominently than, AI summaries during major events.
Google Discover: The New Lifeblood of Web Traffic
As traditional web search traffic declines, a new hero has emerged for publishers: Google Discover. The Define Media Group report indicates that Discover traffic grew by 30% across their portfolio during the same period that search clicks were falling. Perhaps the most significant finding in the report is that, for the first time, Discover and traditional web search now drive roughly equal amounts of traffic for many major publishers.
Google Discover operates differently than Search. While Search is intent-based—meaning a user is looking for something specific—Discover is interest-based. It pushes content to users based on their browsing history and preferences through a feed on mobile devices. This “push” model is proving to be more resilient to AI disruption than the “pull” model of traditional search.
The growth in Discover traffic appears to be a deliberate part of Google’s ecosystem shift. As the company uses AI to satisfy specific queries, it is using Discover to keep users engaged with a curated stream of fresh content. For publishers, this means that “optimizing for Discover”—which involves high-quality imagery, engaging headlines, and timely topics—is now just as important, if not more so, than traditional keyword-based SEO.
Why AI Overviews Shy Away from Real-Time News
One of the most intriguing aspects of the report is the low frequency with which AI Overviews appear for news-related queries. Data from Ahrefs cited in the report shows that AI Overviews appeared for only about 15% of news queries. This is nearly three times less often than in categories like health, science, or technology, where the information is often more factual and less time-sensitive.
There are several logical reasons why Google is exercising caution with AI in the news space:
1. The Risk of Hallucination
Generative AI models are prone to “hallucinations”—confidently stating facts that are incorrect. In the context of breaking news, where details change by the minute, the risk of providing a false summary is high. Google likely views the “Top Stories” carousel as a safer alternative, as it attributes information directly to trusted news brands rather than generating its own interpretation.
2. High Accuracy Stakes
For topics like international conflicts, political developments, or public safety, the stakes for accuracy are incredibly high. Google’s AI systems are not yet fast enough or reliable enough to synthesize a rapidly evolving situation without the risk of spreading misinformation. By prioritizing traditional links to publishers, Google shifts the responsibility for accuracy back to the journalists.
3. The “Top Stories” Advantage
The “Top Stories” carousel is already a highly optimized feature that users trust. It provides multiple perspectives from various outlets in a format that is easy to navigate on mobile. For news queries, this format often provides a better user experience than a single, long-form AI summary, as it allows users to choose their preferred source for a developing story.
Navigating the Algorithm: 2025 and 2026 Core Updates
The volatility in search and Discover traffic has been further complicated by a series of major core updates. The Define Media Group report tracked a sharp increase in Discover traffic following the December 2025 Google core update. This update appeared to reward high-authority news sites with increased visibility in the Discover feed, perhaps as a way to offset the losses seen in organic search.
However, this growth wasn’t permanent for everyone. The February 2026 Discover core update saw some of those gains soften. These rapid-fire updates indicate that Google is still fine-tuning how it balances AI-generated answers with human-written content. For SEO professionals, this highlights the necessity of a diversified traffic strategy. Relying solely on one channel—whether it’s Search or Discover—is increasingly risky in an era where an algorithm update can shift the traffic landscape overnight.
The data from Chartbeat, also mentioned in the report, reinforces this trend. As of mid-2025, Discover had already become the primary driver of Google referrals to news sites. The era of the “search-first” publisher is transitioning into the “feed-first” era, where content must find the user, rather than waiting for the user to find the content.
Practical Strategies for Publishers in the AI Era
With a 42% drop in search clicks, publishers cannot afford to stick to the old playbook. The Define Media Group report suggests that thriving in this new environment requires a strategic pivot. Here are the key areas where publishers should focus their efforts:
Prioritize Real-Time and Original Reporting
Because AI Overviews are less likely to trigger for breaking news, original reporting is more valuable than ever. Publishers should focus on being first to a story and providing unique insights that cannot be easily summarized by an AI. This includes interviews, on-the-ground reporting, and expert commentary.
Double Down on Google Discover
Since Discover is now a peer to Web Search in terms of traffic volume, publishers must optimize for it. This means using high-resolution, compelling images (at least 1,200px wide), crafting headlines that pique curiosity without being “clickbait,” and ensuring that the content is highly relevant to specific audience interests.
Focus on E-E-A-T
Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T) are the pillars of Google’s quality assessment. As AI content floods the web, Google is looking for signals that content is written by humans with actual expertise. Clear bylines, robust “About Us” pages, and citations of primary sources are essential for maintaining visibility in both Search and Discover.
Build Direct Audience Relationships
If the 42% drop in clicks proves anything, it’s that relying on a third-party platform for 100% of your audience is a recipe for disaster. Publishers should use the traffic they still have to build direct relationships through email newsletters, mobile apps, and membership programs. Converting a search visitor into a direct visitor is the only way to truly future-proof a digital publishing business.
Conclusion: The New Normal for Digital Publishing
The report from Define Media Group serves as a wake-up call for the entire digital ecosystem. The 42% decline in organic search clicks is not a temporary dip; it is a fundamental restructuring of how the internet works. Google is no longer just a gatekeeper to the web; it is becoming a destination in its own right, using AI to keep users within its own interface.
However, the 103% growth in breaking news traffic and the 30% rise in Discover referrals show that the demand for high-quality, timely content has not disappeared. It has simply moved. The publishers who will survive and thrive in the age of AI are those who can adapt to these new channels, moving away from commoditized informational content and toward the authoritative, real-time reporting that AI cannot yet replicate. The search landscape has changed forever, but for those willing to evolve, the opportunities for growth remain significant.
