The AI Overview is now a door to AI Mode

An AI Mode doorway is any element inside a Google AI Overview that moves the searcher into an AI Mode conversation instead of out to a web page, and Google added two new ones between late August and late September 2026.

Most teams still plan for AI Overviews and AI Mode as two separate surfaces with separate audiences. That split is getting harder to defend. The interface between them is being rebuilt so that an AI Overview increasingly works as the first turn of an AI Mode session. For anyone measuring AI visibility, the question is shifting from "are we cited in the overview" to "where does the searcher go after the overview."

#Three doorways, added in sequence

The first doorway arrived early in the year. Google began sending follow-up questions from AI Overviews straight into AI Mode, a behavior it tested in December 2025 and announced in January 2026. A searcher who tapped a suggested follow-up got AI Mode laid over the results page, with the original context carried forward. The move still required a deliberate click.

The second removed the click. On August 27, 2026, SEO consultant Chris Long spotted AI Overviews loading fully expanded with an "Ask anything" box and no "Show more" button. Google's statement was that "for some queries, AI Overviews may dynamically expand for topics where our systems determine it's most useful for people," and that if a user has already started scrolling, the expansion stops to keep their place. Android Authority reported the behavior appeared on desktop, often for definition-style queries, while mobile still showed a truncated overview. On desktop, an expanded answer can fill the window before the first organic result appears.

The third doorway looks like a citation and is not one. On September 21, 2026, Gagan Ghotra posted a recording of an AI Overview where underlined anchor text opened AI Mode rather than a web page. Visually, an underlined phrase inside an answer is where a publisher expects its link. In this test, the underline points back into Google.

None of these changes is large on its own. Taken in order, they show a consistent direction: each one shortens the distance between an overview and a conversation, and none of them shortens the distance between an overview and your site.

#More links, but not all of them leave Google

The same weeks brought a finding that looks like good news for publishers. Peec AI data shared by Malte Landwehr showed 26% of AI Overviews containing external links within the answer text, measured as daily averages from August 25 to September 20, 2026. Search Engine Journal flagged the limits: the chart does not state how many queries were sampled or which markets and devices were covered.

Put that number next to the Ghotra recording and a counting problem appears. A link inside an AI Overview can now resolve to three kinds of destination: a publisher page, a Google property, or an AI Mode conversation. A tracker that counts "links in the answer" without resolving where each one goes will report rising link density even if the share pointing at the open web stays flat. As SEJ put it, neither source says what share of links point to external sites versus AI Mode.

#Why the destination matters

The reason to care about which surface the searcher ends up in is that the two surfaces send very different amounts of traffic. In a preregistered field experiment, redirecting every search into AI Mode cut external click-through by 18.8 percentage points against normal Google. We covered that study and its caveats in AI click loss now has a causal number. The short version is that AI Mode is a different traffic regime from AI Overviews, and that arm forced every search into AI Mode, which is heavier use than any real searcher shows today.

The doorways matter because they move real users along that path gradually. No one flips a switch that sends all searches to AI Mode. Instead, a growing share of sessions start as an overview, expand by default, and continue as a conversation because the input box is already on screen. The experiment gives the endpoint. The interface changes decide how fast traffic drifts toward it.

#Search Console will not show you the drift

The natural place to look for this shift is Search Console, and it is poorly suited to the job. Google's documentation says sites appearing in AI features such as AI Overviews and AI Mode are included in the overall search traffic and reported in the Performance report under the "Web" search type. There is no standard row that says "this impression came from an overview that expanded into AI Mode."

Position is also in flux. On September 16, 2026, John Mueller said position and impression tracking for AI Mode and AI Overviews will evolve over time, that "there are edge-cases," and that the goal "is not a written-in-stone absolute truth for position counting". He added that Google will update documentation when there are significant changes. For trend analysis, that means a position series spanning this period may shift for reasons unrelated to your content.

#What to change in your measurement

Resolve every link to its destination. When you capture AI Overviews, record the final URL of each link, not just its anchor. Classify each as publisher, Google property or AI Mode. Report the external share separately from total link count.

Log expansion state. Store whether the overview loaded collapsed or expanded, and on which device. An expanded overview with an input box is a different page from a collapsed one, even when the answer text is identical.

Track AI Mode as its own query set. If a query now opens into AI Mode by default, the overview citation is only the first turn. Run the same query directly in AI Mode and record who gets cited there. The published overlap data we summarized in AI Mode is not AI Overviews is the reason not to assume an overview citation carries over.

Annotate late August and late September 2026. Mark August 27 (auto-expansion spotted) and September 21 (AI Mode anchor links spotted) on any traffic or click-through chart for Google organic. If click-through on informational queries drops without a ranking change, these are candidate explanations to test before blaming content.

Read Search Console position loosely. Compare clicks and impressions over matched periods, and treat average position for AI-heavy queries as an approximate signal until Google documents the counting.

#The practical read

Being cited in an AI Overview is still worth tracking. It is becoming a weaker proxy for being seen by the searcher who clicks. The work now is to follow the session one step further: into the expanded overview, through the links that stay inside Google, and into the AI Mode answer that follows. That is where the traffic decision is being made.
