Google is testing the vertical left sidebar from AI Mode directly on the main Google Search results page, a move that places the AI chat interface one step closer to becoming the default search experience. Search consultant Damien Andell spotted the layout and posted a screenshot on X, reporting what appeared to be a full rollout of the new interface.

The sidebar carries the small "super G" Google logo on the left side of the results page, alongside chat history lines, an entry point to start a new AI Mode chat, and a settings icon. Until now, this vertical rail appeared only after a user clicked into AI Mode from the homepage. In the test configuration, it sits on the standard search results page for every query.

Is the sidebar fully rolled out?

The evidence says no — at least not yet. Andell wrote on X: "Is the sidebar now the default Google sidebar for search engine results pages (SERPs)? I know it was already there when you clicked the AI Mode button on the homepage, but now it's the default for every search."

He believes the change is fully live. But Barry Schwartz of Search Engine Roundtable, who first reported the sighting, could not replicate the layout in any of his browsers. That mismatch points to a limited experiment rather than a confirmed rollout. Google has made no official statement on the test, so everything known about it rests on user screenshots rather than confirmed search-engine communication.

The distinction matters. Google routinely runs interface experiments across small user segments, and many of them never ship broadly. A single user's screenshot, however credible, is tool-level signal — evidence of a test, not evidence of a policy or product decision.

What does this change for site owners?

For now, nothing concrete. The sidebar does not alter rankings, indexing, or how content appears in results. What it does signal is trajectory: Google keeps looking for ways to make AI Mode (Google's conversational, chat-based search experience built on Gemini) more accessible from the main search interface.

If the sidebar ships, AI Mode gains a persistent presence on every results page. Users would see their chat history and a one-click path into conversational search without first seeking out the AI Mode button. That lowers the friction of switching between traditional blue links and chat — and gradually normalizes the chat surface as part of core search.

For publishers, each interface change that nudges users toward AI Mode raises the familiar strategic questions: how traffic arrives when answers are generated conversationally, and how visibility works inside a chat-first results page. The sidebar itself changes none of those mechanics today, but it is another marker on the road Schwartz identified — bringing AI Mode "one step closer to becoming the default for Google Search."

A second signal: Gemini conversations appear in the sidebar

A follow-up observation sharpened the picture. SEO consultant Marie Haynes reported on X that the sidebar appears to be integrating with the broader Gemini ecosystem. "Anyone else seeing this? If I go directly to AI mode, I see my Gemini app conversations in the sidebar," she wrote.

If accurate, that means the rail would not simply serve AI Mode sessions in isolation. It could surface conversations from the Gemini app — Google's general-purpose AI assistant — inside the search interface, tying search chats and assistant chats into one continuous history. As with the sidebar itself, this observation comes from a single practitioner report and awaits broader confirmation.

What to watch next

The practical questions for the coming weeks: whether the sidebar appears for wider user segments, whether Google confirms the test publicly, and whether Gemini conversation history becomes a standard part of the search results page. Site owners and SEOs should monitor their own browsers, track any Google statements on AI Mode distribution, and watch the X forum discussion where these sightings first surfaced.
