Google is cementing its transition to an AI-first interface through persistent sidebars while simultaneously handing advertisers more granular controls to stop automated campaigns from cannibalizing high-value search budgets.

Google Tests AI Mode Left Sidebar On Main Google Search Results Page
Google is testing a persistent left-hand sidebar on the main search results page similar to the interface used in Gemini AI mode.
The sidebar includes access to chat history, a 'start chat' button, and settings icons.
Early reports suggest the feature may be integrating cross-platform conversations from mobile Gemini overlays.
Why it matters
A persistent sidebar would signal a permanent shift toward an AI-first search interface, making conversational search a default behavior rather than an optional mode.
