Bing is testing a change that replaces the Copilot branding with "AI Mode" in its search tabs, according to a report from Search Engine Roundtable. The test signals that Microsoft may be rethinking how it labels and positions its AI search experience inside Bing's core navigation.

The report, published by Barry Schwartz at Search Engine Roundtable, describes the change as a limited test rather than a confirmed rollout. Users in the test group see "AI Mode" appear where the Copilot tab previously sat among Bing's search filters and tabs. As with all interface tests of this kind, Microsoft has not confirmed the scope of the experiment, how many users it includes, or whether the new labeling will ship broadly.

That distinction matters. Interface experiments at major search engines routinely run for weeks across small user samples before the company either expands them or abandons them. A tab test does not equal a product decision, and Microsoft has offered no public statement on the change at this point.

What the test does indicate is a naming problem Microsoft appears to be working through. The company currently sells "Copilot" as a brand across Windows, Office, Edge, and its consumer AI assistant. An "AI Mode" label inside Bing search would align Microsoft's search product with the broader industry vocabulary — Google, notably, brands its generative search experience as "AI Mode" as well. If the test becomes a rollout, Bing would be matching Google's terminology for a functionally similar entry point.

For publishers and search marketers, the practical significance is straightforward. The tab in question is the doorway to Bing's conversational, AI-generated answers rather than its traditional blue links. Any change that makes that doorway more prominent, more clearly labeled, or more inviting to click could shift more queries into AI-answer surfaces — and away from the organic results page. Whether this relabel achieves that is unknown; the test covers naming, and there is no reported evidence of changes to how the underlying AI results are generated or cited.

The reporting describes an observed interface variation, not a policy announcement. No ranking implications, no changes to answer citations, and no monetization shifts accompany the test as described. Anyone claiming SEO impact from this alone would be extending well beyond what the source shows.

Microsoft's history with Bing interface tests argues for patience. The company has cycled through several AI branding arrangements since integrating conversational answers into search — including periods where Copilot sat inside results pages, alongside them, or in a dedicated tab. This latest test continues that iteration pattern rather than breaking from it.

Search professionals should watch three things going forward: whether the "AI Mode" label expands beyond the initial test cohort, whether Microsoft issues a formal statement confirming or explaining the rename, and whether Bing's AI answer surfaces themselves see any parallel changes in visibility or citation behavior. Until Microsoft confirms a rollout, this remains a signal worth noting — and nothing more.
