Interpretation
Cumulative Layout Shift Interpretation
The data paints a clear, slightly jittery picture: while the web's median CLS is hovering around a passable 0.10, a persistent plague of ads, lazy elements, and dynamic content means over a third of user sessions are still being jerked around by unpredictable layout shifts.
