AI Content, AI Overviews, and the Rise of Zero Clicks: Google’s May 2025 Update

If you are here, either you’ve already heard about the term “zero-click searches” in Google Search or you’re noticing a sudden drop in site traffic due to it. Either way, this post is for you.

Google’s May 2025 core update brought two things into sharp focus: the way we approach AI-generated content (AI GC), and the increasing presence of AI Overviews — which are directly linked to the rise of zero-click SEO scenarios.

If your site has experienced ranking fluctuations, lower CTRs, or traffic drops, the update may be the reason. Let’s break down what changed, what it means, and how to respond — especially if you rely on organic traffic.

Google clarified in this update that it’s not penalizing AI-generated content outright. What it is targeting is low-quality AI content — mass-produced, unoriginal, or unhelpful content that doesn’t provide value to the user. This aligns with their ongoing Helpful Content System initiative.

Specifically, the May core update aimed to:

• > Devalue mass-produced, low-value AI content
• > Promote content backed by clear expertise or unique insight
• > Reward sites with a strong reputation in a given niche

So if you’ve been using generative AI responsibly — to support and scale high-quality content — you’re likely in the clear. But if you were chasing keyword coverage with generic posts, this update likely impacted your rankings.

Google’s AI Overviews are now surfacing in a much wider set of search queries, especially informational ones. These AI-generated summaries show directly on the SERP — reducing the need for users to click through to actual web pages. Welcome to the world of zero-click SEO.

This change has made the impact of zero-click searches more pronounced than ever before, especially after the Google May 2025 algorithm update.

• > Broad how-to, what-is, and comparison questions
• > Exploratory queries (e.g., “best ways to…” or “why does…”)

• > Local intent (e.g., “dentist near me”)
• > High-stakes or sensitive topics (health, money, legal)
• > Commercial or product-heavy queries

Traditional tactics — like writing dozens of keyword-optimized blog posts just to target long-tail phrases — are becoming less effective. In the age of AI Overviews, Google wants to showcase trustworthy sources directly in its AI answers.

Here’s what your content now needs to do:

• > Go deeper than the AI summary
• > Offer clear perspective or real-world insights
• > Be structured with schema for use in snippets, FAQs, and Overviews

If your site is cited in the AI Overview itself, that’s still a win — both for visibility and authority — even if you get fewer clicks.

Here are actionable steps to strengthen your SEO post-May update:

• > Revisit top-performing informational pages.
  Are they appearing in AI Overviews? If not, refine structure or content to improve inclusion.
• > Tighten weak or generic content.
  Remove or rewrite low-quality AI-generated content that adds no real insight.
• > Demonstrate real expertise.
  Use bylines, unique commentary, and niche-specific examples — Google rewards first-hand expertise.
• > Implement structured data.
  Add schema for FAQs, How-Tos, and authorship to make your content machine-readable and visible.
• > Focus on value, not just volume.
  Shift from pumping out posts to becoming a trusted source Google can cite in its AI-generated responses.

In short: The SEO strategy for 2025 and beyond must evolve. We’re no longer just writing for users or Googlebots — we’re writing for AI summarizers.
