最新报道:Google is introducing AI-powered updates to Search and Discover, including a "Hide sponsored results" button that collapses ads but keeps the "Sponsored" label visible as users scroll. The changes also group text ads under headers above and below AI Overviews, limit ads to four per group, and add a "What's New" sports update feed in the U.S. Additionally, Discover will feature AI-driven topic previews in the U.S., South Korea, and India, rolling out across desktop and mobile.
