If you’ve been monitoring your organic performance lately, you may have noticed a dizzying chart in Google Search Console (GSC): impressions reaching record highs while clicks drop sharply. This trend has perplexed marketers and SEO consultants alike. It’s so widespread and impactful that it has been termed “The Great Decoupling”, a departure from the long-held belief that impressions naturally drive clicks. This article explores why this is happening, how to respond, and what it means for Vimar.

What Is “The Great Decoupling”?

At its core, the Great Decoupling captures the growing gap between search visibility (impressions) and user engagement (clicks). Once closely aligned, these metrics now pull apart—even when impressions soar, clicks diminish.

Industry data from Ahrefs paints a stark picture:

  • In late 2024, the correlation between daily impressions and clicks was +0.425, indicating they moved together.
  • By early 2025, it flipped to –0.352, showing impressions rising as clicks fell.

This trend has become unmistakable among publishers, e-commerce sites, and service-based businesses worldwide. As their impressions climb, the clicks die down.

The Primary Drivers Behind the Disconnect

What changed so drastically in early 2025? Two key developments reshaped search behaviour:

AI Overviews: Double Impressions, Fewer Clicks

Google’s midday 2025 rollout of AI Overviews (part of AI Mode in search results) transformed how queries are answered. These dynamic summaries appear at the top of SERPs, often citing popular articles, thus giving those pages two opportunities for impressions:

  1. The traditional blue link
  2. Within the AI Overview box

This double exposure inflates impression counts on GSC—and yet users frequently get their answers without clicking

The Rise of Zero-Click Search

With AI Overviews providing instant answers, users no longer need to click through. Studies show that queries triggering Overviews experience ~34.5% lower click-through rates compared to similar keywords without them

This combination—more impressions, fewer clicks—creates a visible “crocodile mouth” pattern in GSC reports.

The Data That Reveals the Shift

Multiple analyses back this up:

  • Ahrefs’ study of 300,000 keywords shows a dramatic average CTR drop of 34.5% on Overview-enabled queries
  • At Google Search Central Live 2025, Martin Splitt confirmed that AI Overviews lead to higher impressions but reduced clicks 
  • Search Engine Roundtable and others report that this trend is broad—spanning sites of all sizes—and “here to stay”

Industry voices echo the findings:

“Impressions up and clicks down correlate directly with the large‑scale rollout of AI Overviews.”

Google Speaks: Official Confirmation

Google itself has acknowledged the shift:

  • Martin Splitt (June 17, 2025, Warsaw event):
     “If things are being shown in AI Overviews, you will probably see fewer clicks… your impressions are going to go up… clicks are likely to stagnate or fall a little bit.
  • He also noted that traffic from AI Overviews tends to convert better, even if fewer users click through.

Google emphasises quality over quantity: they’re shifting from visibility-focused SEO toward conversions and trust.

How Different Sites Are Affected

In this new landscape, traditional organic metrics are misleading. Here’s what to monitor instead:

  1. Impressions in AI Overviews
  • Use tools with SERP Feature filters (e.g. Ahrefs) to see performance in regular vs. AI results.
  1. Click-Through Performance & Intent
  • Compare CTRs across query types.
  • Track conversions (e.g., form submissions, product trials) rather than clicks.
  1. Branded Search Volume
  • Citations within AI Overviews build brand awareness—even if users don’t click.
  1. Engagement Quality
  • For visitors who click through: measure depth, scroll, session duration, and conversion behaviour.
  1. AI and LLM Visibility
  • Track citations beyond Google—e.g., ChatGPT, Perplexity, Bing Chat—that cite your content.

These metrics reflect impact, not just exposure.

Strategic Adaptations for Websites

To thrive amid the decoupling, adapt in five key ways:

  1. Optimise for AI Overviews
  • Structure content with clear questions and concise answers (bullet points, summaries).
  • Use schema markup, headings, lists, and tables for readability.
  • Provide factual, authoritative insights to encourage citing.
  1. Build Strong Brand Authority
  • High-authority domains are more trusted and more likely to be cited.
  • Build backlinks, showcase expertise, and publish expert-authored content.
  1. Shift Funnel Focus
  • Instead of only targeting TOFU content (e.g., “What is X?”), focus on mid- and bottom-funnel content (comparisons, use cases, conversions).
  • Ensure landing pages and product content are structured to convert.
  1. Diversify Traffic Channels
  • Leverage email marketing, social platforms, affiliate referrals, and paid campaigns. Reducing reliance on search minimises risk.
  • Aim to build multi-channel engagement—Google is one lane, not the highway.
  1. Refine Analytics Systems
  • Update dashboards to prioritise conversions over clicks.
  • Segment AI-sourced traffic separately.
  • Educate stakeholders on the shift and set realistic expectations.
  1. The Broader Shift Toward “Answer Engines”

The decoupling is part of a broader trend: search is evolving into answer engines. Google, ChatGPT, Perplexity, Bing Chat, and others are moving from list-based results toward AI-generated answers.

  • Queries are longer, more conversational 
  • Answer engines prioritise single, authoritative responses rather than linking multiple websites.
  • Brands must be found, cited, and trusted—not just ranked.

If you’re not appearing in AI-generated spaces, you’re invisible—even if your SEO ranks are good.

Conclusion 

For Vimar, the Great Decoupling is not just a warning—it’s a wake-up call to realign digital strategy with how users engage today. While impressions may continue to rise and clicks dwindle, this shift signals a deeper transformation: search is becoming more about answers than links, and visibility now hinges on authority, clarity, and structured content. 

To succeed, Vimar must focus on earning trust, being cited in AI Overviews, and delivering content that satisfies intent at every stage of the buyer journey. This is the moment to look beyond traffic volume and double down on meaningful engagement, brand strength, and conversion-driven content. Adaptation here isn’t optional—it’s the new foundation for digital growth.
