Google Tests Removing AI Mode Button as Brand AI Overviews Shift Right

Google is testing the removal of the AI Mode button from its main search bar, according to reports surfacing in search forums on November 3, 2026 — a test that Search Engine Roundtable could not replicate but considers plausible given Google's habit of withholding features from small searcher subsets to measure performance differences. The test landed on the same day Google confirmed it will entirely turn off Google Search, Gemini, Gemini Notebook, and Gemini in Classroom for K-12 schools.

The K-12 decision is the firmest statement of the day. "Access to these products will be entirely off for K-12 student accounts until school administrators explicitly turn them on," Google wrote. The change puts the onus on administrators to re-enable the tools.

What moved on the results page?

Google has relocated AI Overviews (Google's AI-generated answer summaries atop search results) for many brand-related keywords from the top or middle of the main results section to the right-hand column. For brand owners, the practical question is what this does to click distribution — a right-rail placement pushes organic listings back toward the center of the page while shrinking the AI answer's visual dominance.

Separately, AI Mode appeared to show a pronounced self-preference bias in one weekend test. When asking Google's AI Mode for flight information, 100% of links within the responses pointed to Google Flights — no third-party travel sites appeared. That finding is a single observer's test, not a confirmed Google statement, but it is likely to draw attention from Digital Markets Act (DMA) regulators in Europe, where Google's practice of favoring its own services is already under scrutiny. The same week, Reuters reported the EU fined Google €1.49 billion for blocking advertising rivals.

Which indexing problem did Google flag?

Sites whose homepage is the only indexed page — especially those whose other pages were previously indexed and have dropped out — may have a quality issue, Google indicated. This is a diagnostic signal for site owners: a sudden collapse to homepage-only indexing warrants a quality review rather than a technical fix alone.

Google's Search Advocate John Mueller also explained how to keep pop-up dialogs out of Google Search using the robots.txt file, including the specific approach for JavaScript-driven pop-ups.

What changed in Google Ads?

Two confirmed Ads updates landed:

• Performance Max filtering. Google updated its help document "How Performance Max interacts with other campaigns in your account" to state that Performance Max campaigns (Google's automated, cross-channel campaign type) "may also filter out navigational or brand-specific search queries to prioritize serving them through dedicated Search campaigns."
• Asset scheduling with day grouping. Advertisers can now group days — weekends versus weekdays, for example — under advanced options within asset scheduling.

Elsewhere in the paid ecosystem, Search Engine Watch reported that Google AI Mode is now showing four ads at the bottom of responses, and that Google is testing removing other tabs from the AI Mode header.

What else surfaced in the forums?

Community threads added texture to the day: a BlackHatWorld report of a sudden total traffic drop in Google Search Console resembling deindexing; Radu Oncescu spotting Google testing emojis in the "More trending discussions" module; and a Reddit question about a blog category page drawing thousands of impressions with zero clicks.

Similarweb data showed worldwide traffic to Claude's upgrade page rebounding in September ahead of Anthropic's IPO — 17.6 million visits, nearly recovering from May and June highs of 18.6 million after a July dip to 16.8 million and an August low of 14.7 million. Anthropic also released an amended IPO prospectus with third-quarter financials, per CNBC.

Among the day's personnel notes, Ali Eslami announced his departure from Google DeepMind after nearly 12 years, writing: "My view is that we now know how to build AGI, even if we don't fully understand it yet." He joins DiscoLoopAI.

Google, meanwhile, held a "Sleigh the Season with Google" event at its London office, complete with branded cookies and a Christmas tree.

What to monitor next: whether the AI Mode button removal expands beyond the initial test cohort, how widely the right-column AI Overviews roll out for brand queries, and whether DMA regulators respond to the Google Flights linking pattern.
