A page’s CLS score is computed by multiplying the proportion of the user’s screen that shifted unexpectedly when loading by the distance it traveled. Sites sometimes even face having half of the screen impacted by the content shift. That is annoying to viewers. Simultaneously, the distance the content had to go on the screen factors in. Therefore, to calculate the CLS score, multiply the impacted screen area (0.5) by the distance traveled (0.15) and you can gain a useful score.
