Question: Which of the following does Google consider a good CLS score?
- 0.1
- 0.5
- 1.0
- 2.5
Explanation
A Cumulative Layout Shift (CLS) score of 0.1 or lower indicates minimal unexpected layout shifts, providing a stable and predictable user experience. Maintaining a low CLS helps meet Page Experience signals and supports SEO performance. Scores above 0.1 suggest that content moves unexpectedly, which can frustrate users and negatively impact rankings.
Why the other options are incorrect
B) 0.5 exceeds the recommended threshold and reflects noticeable layout instability.
C) 1.0 indicates significant layout shifts that degrade user experience.
D) 2.5 represents severe instability, far outside acceptable CLS ranges.
