Impressions up, clicks down? How to tell whether AI Overviews are behind your traffic drop

If Search Console shows impressions steady or rising while clicks fall, AI Overviews are one possible explanation, not a diagnosis. Before changing your pages, check whether rankings, titles, snippets, competing results or reporting changed, and whether AI answers appear for the affected searches. The same headline numbers can have different causes.

This guide walks through how to tell them apart using free tools, and what is (and isn't) within your control.

Why impressions and clicks can move in opposite directions

An impression records a link to your page being shown under Google's counting rules; a click records someone following it. More impressions do not necessarily mean more clicks. People may choose another result, find an answer on the results page, or encounter your page for a different mix of searches. (Search Console counting rules)

AI answers are one possibility to investigate. The research below describes patterns across groups of searches; it cannot tell you why an individual website lost clicks.

• Independent evidence: Pew Research Center analysed March 2025 browsing from 900 US adults and reconstructed search results in April. Users clicked a traditional result in 8% of visits when an AI summary appeared, compared with 15% when it didn't. They clicked a link inside the summary itself in 1% of visits. (Pew Research Center, 22 July 2025, checked 26 Oct 2026)
• Industry study: Ahrefs compared desktop click-through rates for 300,000 keywords and found AI Overview presence associated with about 58% lower CTR for the top-ranking page relative to its forecast. The effect was smaller lower down the page. Ahrefs notes this is a correlation, relies on a forecasting method, and covers desktop only. (Ahrefs, 4 Feb 2026, checked 26 Oct 2026)
• Google's view: Google says total organic clicks have been "relatively stable" year on year and that clicks from results with AI Overviews are "higher quality", meaning people spend longer on the site. The post does not provide the underlying dataset. (Google, 6 Aug 2025; Google Search Central, AI features and your website, checked 26 Oct 2026)

These are not equivalent measurements or a consensus on causation. Pew and Ahrefs report associations in their samples; Google's statement concerns aggregate traffic and click quality. Use them as context, then examine your own Search Console data alongside analytics and enquiries.

How Search Console counts AI Overviews and AI Mode

It helps to know how these features show up in your reports, because they're mixed in with your normal search data.

According to Search Console Help (checked 26 Oct 2026):

• AI Overview and AI Mode activity is included in overall Web search performance. Current search-type controls distinguish Web: text-based and Web: multimodal; use a consistent type when comparing periods. (Current report setup)
• Clicking an external link to your page from either feature counts as a click. Standard impression rules apply; visibility requirements depend on the result's presentation, so do not assume every hidden link earns an impression.
• An AI Overview occupies a single position, and every link inside it is given that same position. That position describes the containing result, not the prominence of each individual link within it.

That distinction matters when interpreting average position: it is not a measure of attention or a guarantee of clicks. Read it alongside impressions, CTR and the actual results layout.

Since 31 August 2026, Google has also offered separate generative AI performance reports in Search Console, showing impressions from AI Overviews, AI Mode and AI features in Discover by page, country, device and date. At the time of checking they show impressions only, not clicks, and sites with few AI impressions may not see them. (Google's announcement and report documentation, checked 26 Oct 2026)

Step 1: Rule out a reporting change first

Not every drop is real. Search Console figures can shift because of how Google collects or counts data.

Google recommends checking the Search Console Data Anomalies page when investigating a traffic drop: a processing change or logging issue can affect the chart. (Google traffic-drop guidance)

What to check:

• Note when the change began. A sudden step or gradual slope is a clue, not proof of a particular cause. Compare the timing with reporting notices and changes to your own site.
• Compare like with like. Use the date comparison in the Performance report and compare the same weeks year on year, and account for seasonal events such as school holidays or Chinese New Year, whose calendar dates can move.
• Check your analytics too. If Search Console clicks fall but organic visits in your analytics tool are flat, the difference may be in measurement rather than real visitors.
• Rule out site problems. A drop in clicks can also come from pages falling out of the index. Check the Page indexing report and run the URL Inspection tool on your most important pages. Our Search Console set-up guide explains where to find these.

Step 2: Find out which searches and pages lost clicks

Next, narrow the drop down. In the Performance report:

1. Turn on Clicks, Impressions, CTR and Average position.
2. Open the Date filter, choose Compare, and select two ranges, such as the last three months against the same period a year earlier.
3. Open the Queries tab and sort by the difference in clicks.
4. Repeat on the Pages tab.

Google documents this comparison workflow and sorting by clicks difference. It also identifies weak titles or snippets and competing rich results as possible explanations for stable impressions with fewer clicks. (Google traffic-drop guidance)

Use these patterns as prompts for investigation, not definitive diagnoses:

To check whether an AI Overview is involved, search the affected queries yourself in a private browser window. Note whether an AI Overview appears and whether your page is linked in it. Results vary by person, location and time, so treat this as a spot check, not proof. Our guide to checking whether AI tools mention your business explains how to run these checks consistently.

Step 3: Decide whether the lost clicks were worth having

A falling CTR on a general how-to article isn't necessarily a business problem; assess its business impact before choosing a response.

Ask what each affected page was meant to do:

• Informational pages that answered a quick question. If someone wanted a one-line answer, they may now get it from the AI Overview. Check whether the page previously helped generate enquiries or assisted later visits before deciding those clicks had little value.
• Pages that lead to enquiries. Prioritise service, pricing and location pages that contribute to your enquiries. If these are losing clicks, investigate properly.
• Pages where people need detail or help. If a question genuinely needs more than a summary — a comparison, a process, a local rule — make sure the page clearly offers that depth. That gives interested readers a reason to visit, without guaranteeing that they will.

A hypothetical example: [Business name], a renovation contractor, sees its "How long does HDB renovation approval take?" article keep the same impressions but lose half its clicks. Meanwhile, its "Kitchen renovation" service page holds steady. That pattern alone does not show whether an AI Overview caused the decline. The contractor should inspect the affected results and check enquiries before deciding what to change. A useful content check is whether the article links clearly to the service page and explains what the contractor handles.

What you can do about it

None of these guarantees clicks, rankings or a place in an AI Overview. Google decides what to show. These are the things within your control.

Make the click worth it. Useful additions — a worked example, a checklist, a price range with conditions, a clear explanation of how your service works — give people a reason to visit. Our guide on writing pages AI answers can quote covers the structure.

Strengthen the pages that bring enquiries. Clear service pages that answer "what, where, how much, how long" tend to serve buying searches, and help visitors decide whether the service fits their needs. Treat this as a content recommendation, not a prediction about AI results.

Keep the basics in order. Google says there are no extra requirements to appear in AI Overviews or AI Mode: pages need to be indexed and eligible to show a snippet, and normal SEO practice applies. (Google Search Central, checked 26 Oct 2026)

Measure more than clicks. Track enquiries, calls and form submissions alongside search clicks. If clicks fall but enquiries hold, your search visibility may be working differently rather than worse.

Be careful with opting out. Google lets you limit what appears in AI features with nosnippet, data-nosnippet or max-snippet, but these also affect your normal search snippets. (Google's preview controls guidance) Our recommendation: use these controls only for a clear business reason, not as an assumed way to recover clicks.

What's in your control, and what isn't

In your control: which pages you prioritise, how useful and clear they are, whether they're indexed, how they link to your services, and what you measure.

Not in your control: whether Google shows an AI Overview for a search, which sources it links to, how many people read the summary and stop, and how Google changes these features over time.
