The problem
What you're seeing
Elements jump around as your page loads — ads, fonts, images — and CLS sits well above 0.1.
How we fix it
Our approach
We reserve dimensions for every dynamic element, swap font-display for the right strategy, and remove jank in the third-party tag manager. CLS goes under 0.05 and stays there.
What you get
