The calculation of the CLS is rather complicated and is expressed as the product of two values, the impact component and the distance component using this formula: punteggio layout shift = componente impatto * componente distanza The impact component measures the normal space occupied by an element in the window and the space it occupies after its movement . The union of the visible area of the element before and after the movement determines the percentage of the total view and therefore its impact component. The distance component is the greatest distance an unstable element has covered in the box while moving (horizontally or vertically) divided by the largest size of the box (width or height, whichever is greater) and is always measured in percentage. The CLS is therefore the product of these two components and for a good UX it should be less than 0.1.
Example of Cumulative Layout ShiftExample of Cumulative Layout Shift The image above shows a block of text - which takes up half the visible part of the screen - moving down 25% of the window height. The red rectangle indicates the union of the visible area of the element before and after the move, i.e. 50% + 25% = 75% of the window, so the impact component is 0.75. And since the unstable element has moved 25% of Buy TG Number Data the height of the window, the value of the distance component is 0.25. Based on the formula written previously, the CLS score is equal to 0.75 * 0.25 = 0.1875 which can be improved.

In this way it is possible to exploit the API to independently track user behavior by using Google Tag Manager to transfer the metrics to Google Analytics and export them to Google Data Studio . Ultimately we can say that the introduction of Core Web Vitals reminds us once again that the main objective remains to create sites that are easy and quick to navigate, especially for mobile users. Underestimating these aspects not only risks decreasing the conversions of our site but the danger is remaining confined to the lower positions of the SERP.
