Lily Ray published analysis of the March 2026 Core Update impact - it's tight and easy to skim but if you just want the highlights:

• "Direct from source" websites got a boost - websites where you can do/watch/buy/book something right there on the site increased visibility.
• Aggregators/commentators took a hit - websites that list, review, and talk about other companies' products & services lost visibility.
• UGC based sites are doing fine - even though sites like Reddit, Quora, Wikipedia & YouTube took a hit this time around, they had huge visibility boosts in the past so this looks more like a balancing correction than a smackdown. When you zoom out to the big picture for these guys it's still an overall upward trend over the last few years.

Full analysis has lists of absolute/percentage winners & losers and a closer look at specific verticals including entertainment, travel, health, etc.
