No confirmed “named” Google core update today (March 6, 2026), but the SERPs are definitely in motion. The loudest signal is ongoing ranking volatility: Search Engine Roundtable shows the tracking tools and chatter staying heated into early March, even after the February 2026 Discover-focused update finished rolling out on February 27.
Meanwhile, the AI layer keeps reshaping what clicks you get. Search Engine Journal highlights Google’s push to make AI Overview and AI Mode sources more clickable, including more prominent link treatments and desktop hover link popups. That is a small UI change with a big consequence: it can shift traffic to whichever sources get surfaced inside the AI answer.
Action for site owners: watch Search Console for page-level drops, refresh top pages for clarity and citations, and test titles and intros to match “answer” intent, not just keywords.
