Tracking The Business Impact Of AI Overviews

TL;DR

AI Overviews (AIO) are changing search behaviour. Clicks drop when summaries answer the query, fewer people click the cited links, and “zero-click” sessions are rising. By tracking presence rate, AI Overview CTR, zero-click, and source mix, leaders can decide where to shift content and budgets with data, not opinion.

AI Overviews are no longer an experiment; they are already reshaping search results. Fewer users are clicking through to websites when an AI summary is shown. Instead, many stop at the search page itself or click only the AI-selected sources. This shift means organisations can’t rely on old traffic patterns. Tracking the AI Overviews SEO impact with hard numbers helps leaders protect performance and redirect resources where they matter.

Why is This Important?

Research shows that when an AI summary appears, click-through rates (CTR) can drop by more than a third. Zero-click behaviour is also higher, with more users ending their search without visiting a site. Because AI Overview coverage varies across industries and countries, every business needs to measure its own numbers; otherwise, decisions may be based on misleading averages.

What Should You Track?

To get clarity, track four things:

• How often your queries trigger an AI Overview (presence rate).
• CTR with and without AI Overviews.
• How many users stop at the search page without visiting a site (zero-click).
• Which types of sites are cited most often (source mix - government, forums, news, vendors).

How Can You Measure the Impact?

1. Use Google Search Console (GSC) and Google Analytics 4 (GA4). Pull clicks, impressions, and CTR by query from GSC, and connect them to conversions in GA4. This shows not just traffic impact, but business results.

2. Log daily search results. Use a SERP API tool to record whether an AI Overview appears for your tracked queries, and which websites are cited. Over time, you’ll see patterns.

3. Compare CTR on AIO vs non-AIO days. For the same query, measure CTR when AI Overviews appear versus when they don’t. This highlights where summaries reduce traffic the most.

4. Analyse the sources. Check which types of sites get cited most in your industry. If forums or government sites dominate, you may need to adjust your content formats.

5. Make your site “AI-friendly.” Use clear CTAs (like “Try our tool” or “Book a demo”) and structured markup (SoftwareApplication/WebApplication) so AI Overviews can link directly to your tools or pages.

Show & Tell - CTR With And Without AIO

Track CTR for the same query across days with and without AI Overviews. If CTR drops sharply when summaries appear, you have evidence to adjust content or budgets. At the same time, study which sources the AI prefers, and align your formats to increase your chance of being cited.

Takeaway

AI Overviews are changing how users interact with search. Leaders need to move from assumptions to evidence. By setting up a simple, repeatable panel that includes presence, CTR, zero-click, and source mix, you can identify risks early and invest in content and formats that continue to drive results.

• AI Overview (AIO): Google’s AI-generated summary at the top of search results.
• CTR (Click-Through Rate): The percentage of people who clicked your result (Clicks ÷ Impressions).
• Zero-click: When users get their answer from the search page without clicking through.
• Source mix: The types of sites cited in an AI Overview (e.g., government, forums, news).
• GSC (Google Search Console): Google’s tool for tracking search performance.
• GA4 (Google Analytics 4): Google’s analytics tool for measuring site traffic and conversions.
