How Google’s AI Overviews Are Impacting Click-Through Rates (CTR)

In 2025, one of the biggest changes to SEO isn’t an algorithm update—it’s a UI shift.

Google’s rollout of AI Overviews (formerly known as Search Generative Experience, or SGE) is reshaping how users interact with search results. Instead of a list of blue links, many queries now return a summary powered by generative AI, often with cited sources embedded in the overview.

The result? Click-through rates (CTR) are changing—dramatically.

In this article, we break down how AI Overviews are impacting CTR, what early data is showing, and how to adapt your SEO strategy to protect (and even grow) your visibility in the AI-first SERP.

What Are Google AI Overviews?

AI Overviews are Google’s AI-generated summaries that appear at the top of certain search results. These overviews:

• Provide multi-sentence answers generated by Google’s LLMs

• Often appear above traditional organic listings

• Include cited sources (links to websites used to construct the summary)

• Offer follow-up questions or prompts

They’re designed to answer the query instantly, reducing the need for users to click through to external websites.

The Core Issue: Zero-Click Search Is Rising

AI Overviews are accelerating the zero-click trend—where users get what they need directly from the SERP and don’t click any result.

According to early studies:

• Pages that once received 30–40% CTR may now only get 3–8% when cited in AI Overviews

• For some queries, especially informational or broad questions, clicks are nearly eliminated

• Websites that aren’t cited at all may see major traffic drops

CTR erosion is real—and it’s reshaping how SEOs evaluate performance.

How AI Overviews Change CTR Behavior

Let’s break it down:

✅ If your site is cited in the AI Overview:

You may receive a modest share of traffic (especially if your snippet is linked clearly), but far less than a traditional #1 organic ranking.

❌ If your site is not cited in the AI Overview:

Even if you rank organically at #1–3, your result is likely pushed below the fold—and CTR suffers heavily.

⚠️ If your site is the sole or dominant citation:

You might capture higher-than-average CTR within the AI Overview block—but that’s increasingly rare.

Example: How a Traditional SERP vs. AI Overview Affects CTR

Traditional SERP:

• Position #1: ~27–30% CTR

• Position #2: ~15%

• Position #3: ~10%

With AI Overview Above:

• Position #1: ~7–10% CTR

• Position #2+: ~1–5%

• AI Overview citation link (if present): ~2–6%

Which Types of Queries Are Affected Most?

AI Overviews are not triggered on all searches, but they are dominating for:

How to Protect and Improve CTR in the AI Era

1. Optimize for AI Overview Inclusion

It’s better to be cited than buried. To increase your chances:

• Use structured content with H2s and bullet points

• Answer questions clearly in the first paragraph

• Include TL;DR or summary sections

• Add FAQ schema to eligible pages

• Build topical authority with internal linking

2. Write for Click-Desire, Not Just Keyword Match

AI will often summarize what everyone else says. To earn the click, you need to promise more than what’s in the overview.

• Use curiosity-driven headlines and meta descriptions

• Tease deeper analysis, data, or tools the user can only access by visiting your site

• Create skimmable content that also rewards scrolling

3. Invest in Branded and Navigational Queries

Users searching specifically for your brand or product are less likely to be influenced by AI Overviews.

• Own your branded SERP real estate

• Run Google Ads on high-value branded terms

• Use schema to enhance branded results (site links, reviews, FAQs)

4. Publish Data-Backed, Original Content

Google is more likely to cite authoritative, first-party insights in AI Overviews.

• Publish proprietary research, surveys, or benchmarks

• Include expert quotes and bylines

• Get cited and linked by other authoritative sites

5. Track and Measure AI Impact

While Search Console doesn’t yet break out AI Overview data, you can:

• Monitor sharp CTR drops on top-performing pages

• Use tools like Semrush or Sistrix that track AI-triggered queries

• Conduct Incognito searches to spot AI Overviews in your niche

• Compare device-level click behavior (AI Overviews often show more on mobile)
