Google is testing a change that quietly reshapes how desktop users move through search. When someone reads an AI Overview and clicks 'Show more', they are taken directly into AI Mode rather than back into standard search results. This behaviour has been live on mobile since January 2026. It is now being tested on desktop.
That might sound like a small interface tweak. It is not. It changes the shape of the search funnel in a way that brands and their agencies need to think through clearly.
What Has Actually Changed
Previously, the 'Show more' button on an AI Overview expanded the response within the standard search results page. You stayed in the familiar environment of ten blue links, ads, and traditional organic results. The AI-generated content sat on top of that world.
Now, at least in testing, that click takes you somewhere else entirely. AI Mode is a conversational, generative interface. There are no standard organic results in the way you are used to seeing them. Sources appear differently, the interaction model is different, and the onward journey for the user looks nothing like a traditional SERP.
The significance here is that Google is not waiting for users to seek out AI Mode deliberately. It is routing curious, engaged users directly into it from one of the most prominent positions on the page. The AIO becomes the entrance to a different room, not a preview of the one you are already in.
Desktop Still Carries Significant Commercial Intent
Mobile search volumes are high, but desktop remains the dominant environment for high-value commercial queries - B2B research, considered purchases, complex service comparisons. The kind of searches where a brand's ability to appear as a credible, cited source genuinely influences decisions.
The January 2026 mobile rollout was worth monitoring. The desktop test is worth acting on. If this becomes standard behaviour, a meaningful portion of desktop users who engage with an AI Overview will continue into AI Mode rather than returning to organic results. That affects where your traffic comes from, and frankly, whether it comes at all.
Brands that have relied on strong organic positions below the AIO as a fallback need to think about what happens when that fallback leads somewhere else. Being present within the AIO itself - cited, referenced, visible - becomes more important, not less.
The Citation Layer Is Where This Gets Won or Lost
AI Mode does not generate responses from nothing. It draws on content it can access, assess, and attribute. The brands that appear as sources within both AI Overviews and the deeper AI Mode responses are the ones with content that the model treats as authoritative and relevant to the query.
That means the work of Generative Engine Optimisation - structuring content so it is comprehensible to large language models, building entity authority, answering questions at the right depth and specificity - feeds directly into visibility in this new funnel. It is not separate from this change. It is the response to it.
The same content principles that help a brand get cited in Perplexity or ChatGPT responses apply here. Clear authorship, structured facts, direct answers to specific questions, content that demonstrates genuine expertise rather than surface-level coverage. These are not abstract recommendations - they are what Google's generative systems consistently pull from.
Paid Search Has a Role Here Too
Google has been cautious about how ads appear within AI Mode, but that does not mean paid search is irrelevant to this development. The funnel shift means that some users who would previously have moved through a SERP with visible ads are now in an environment where ad exposure works differently.
For brands running Performance Max or AI Max campaigns, understanding where the user is in their journey when they hit a paid touchpoint matters more than ever. A user deep in an AI Mode conversation has a different intent profile to one scanning a standard SERP. Smart Bidding signals need to reflect that, and campaign structures need to account for the fact that the traditional click-through from a SERP is not the only path to conversion.
This is also an argument for investing in brand visibility at the organic AI layer. If users are moving into AI Mode before they reach your paid ads, the brand recognition built through AI citations can influence the quality of those paid interactions downstream. Organic AI presence and paid search are not separate strategies - they feed each other.
What to Do With This Information Now
This is still a test. Google may roll it back, modify the behaviour, or change the interface significantly before a full desktop launch. But the direction of travel is clear. Google has been progressively pulling users deeper into generative search experiences since AI Overviews launched. This is another step in that direction, not a reversal.
Practically, this is the time to audit which queries your brand appears in within AI Overviews, and to test those queries in AI Mode directly. See whether your brand is cited in the deeper conversational responses. If it is not, that is a content and authority gap worth addressing - not next quarter, but now.
Review your informational and mid-funnel content. Is it genuinely useful to someone in a research conversation, or is it structured primarily for keyword ranking? The former gets cited. The latter tends to be ignored by generative systems. With desktop AI Mode potentially becoming the next step after every substantive AIO, the cost of that gap is about to increase.
