Some desktop AI Overviews are missing the AI Overview label

Some AI Overviews on desktop Google Search are showing without the AI Overview label that normally sits above them. The missing label has been seen on AI Overviews for TV shows and films, while the same panel on mobile still carries it. Google has not said whether this is a test or a bug.

What was seen

The missing label was first noticed on 20 October, on AI Overviews answering desktop queries about shows and films, where the panel appeared with no AI Overview label above it.

The unlabelled results sit at the top of the page in a panel that looks much like a knowledge panel. On a phone, the identical query shows the same panel with the AI Overview label at the top.

This is not a blanket change. Most AI Overviews still carry the label on both desktop and mobile. Only a subset, so far tied to entertainment queries, has turned up without it.

Google has been asked about it and had not responded publicly at the time of writing. AI Overview labels have gone missing before, and that earlier case turned out to be a bug. That history makes a bug the more likely explanation, but nothing is confirmed.

The Semrush drop on the same day

Semrush data flagged on 20 October showed a drop in how often AI Overviews appear in Google results. At least one prominent industry commentator called it a likely tracking problem rather than a real decline, because AI Overviews are still easy to find across most query types. Semrush has not explained the drop.

The two events may be connected. A rank-tracking tool that identifies an AI Overview partly by its label could count an unlabelled panel as something else and report fewer AI Overviews, even though searchers are seeing the same thing. Whether that is what happened at Semrush is unconfirmed.

Why a label matters to tracking

AI Overview visibility figures from third-party tools do not come from Google. They come from the tool fetching results pages and classifying what it finds, and a label is one of the simplest things to classify on. A label that disappears on one device type can move a report without any change in what searchers see.

Google's own documentation says AI Overviews are shown only when its systems decide they add something beyond classic results, so they often do not trigger at all. That built-in variability means the share of queries with an AI Overview moves around anyway, which makes a tracking artefact hard to separate from a genuine shift without checking by hand.

What Google's own reporting shows

Search Console's Generative AI performance report shows how often a site's links appeared in AI Overviews and AI Mode, by page, country, device and date. It is an impressions-only report, split by desktop, tablet and mobile, with no click data. Clicks from AI features are not separated and stay inside the main Performance report under the Web search type.

That gives a Google-side baseline to set against a third-party tracker's count. If a tracker shows AI Overview presence falling while a site's desktop AI impressions in Search Console hold steady, that points to a tracking artefact rather than a real change. Google has not said how unlabelled panels are counted, so the report cannot settle that particular question either way.

Google also says clicks from results pages with AI Overviews tend to be higher quality, with people spending more time on the site. That is Google's description of its own data rather than an independent measurement.

Who this affects in Australia

Businesses paying for AI visibility reporting, through a tool subscription or an agency, are the ones who will notice. A weekly report showing AI Overview presence falling sharply is the kind of thing that prompts a strategy meeting, and this week it may be a false alarm.

The queries involved so far are shows and films, which is not where most Australian businesses compete. The same mechanism would apply to any query set if the label behaviour spreads, and nobody outside Google knows whether it will.

Google's eligibility rules have not changed. To appear as a supporting link in an AI Overview, a page needs to be indexed and eligible to show in Search with a snippet. There are no extra technical requirements, and the usual snippet controls (nosnippet, data-nosnippet, max-snippet and noindex) still apply if you want to limit what Google shows from a page.

Check before you react

October has already produced two cases where data moved and the cause was tracking rather than the market. The ChatGPT referral drop in GA4 earlier this month came from a missing utm_source tag that sent those visits into Direct. The Search Console data delay after the spam update had site owners judging an update on data that had not arrived yet.

This one looks like the same category. Before changing anything this week:

• Pick five to ten of the queries that matter to the business and run them on a desktop browser and a phone, logged out, from an Australian location. Note which ones show an AI Overview and whether it is labelled.
• Compare that with what the tracking tool says for the same queries on the same day. If the tool reports no AI Overview where one is plainly on screen, the tool is classifying it differently.
• Open Search Console's Generative AI performance report, filter by device, and compare desktop AI Overview impressions for the past week with the weeks before. A steady line there next to a falling tracker figure points to a tracking artefact.
• Annotate the reporting week so nobody reads a tool artefact as a trend in three months' time.
• Watch for Google confirming either a bug or a deliberate change. If the labels come back, the tracker numbers should recover on their own.

Google moved inline links higher in AI Mode and AI Overviews last week, and Search Console's generative AI report still counts impressions only, with no click data. Until that changes, a manual spot check alongside the Search Console AI impressions check is the way to confirm what a tool is telling you about AI Overviews.
