• Cumulative Layout Shift (CLS): The amount of unexpected layout changes on your site. Ideally, it should be less than 0.1.

By optimizing your site for these metrics, you can improve your site's ranking, usability, and conversions.

Some tips on how to use Google PageSpeed Insights effectively are:

• Test your site on both mobile and desktop devices, as they may have different performance issues and opportunities.
