Rolled out recently, this update (often dubbed "Helpful Content Update 2.0" in the community) focuses heavily on user intent and content quality. Google's crаcking down on thin content and over-optimized pages, pushing for legit, value-driven stuff. If your site's just keyword-stuffed with no real meat, you're gonna get hit hard in the SERPs.

They've also tweaked the AI detection to sniff out low-effort, spun content - yep, no more gaming the system with cheap tricks. On the flip side, sites with solid UX and E-A-T (Expertise, Authoritativeness, Trustworthiness) are getting a nice ranking boost. My advice? Audit your content, ditch the fluff, and double down on user-first vibes.
