Do Exit Bee ads affect the site's CLS score?

What is Cumulative Layout Shift?

Cumulative Layout Shift (CLS) is a metric calculated by summing all layout shifts that aren’t caused by user interaction. CLS looks at the proportion of the viewport that was impacted by layout shifts, and the movement distance of the elements that were moved.

Have you ever been reading an article online when something suddenly changes on the page? Without warning, the text moves, and you've lost your place. Or even worse: you're about to tap a link or a button, but in the instant before your finger lands—BOOM—the link moves, and you end up clicking something else!

Do Exit Bee ads affect the site's CLS score?

No. Exit Bee ads are loading on top of the content therefore they do not cause any unexpected movement to the website's elements. In addition Exit Bee ads, are loaded only when the visitor is exiting the website, so it is taken into consideration that the mouse or any pointer device is not in the view. In that way we make sure that the visitor will not accidentally click the ad when she was intended to click something else.

How can I test the CLS score of my site?

  • Open Chrome browser and visit the page you wish to check.
  • Right click on the page and select "Inspect"
  • At the new window select the "Performance" tab and click the record button on the left.

  • Now reload the page
  • Navigate the page as a normal visitor and trigger an Exit Bee ad if possible
  • When you are ready click "stop" and wait for the analysis process to finish

Analyse the results

Take a look at the "Experience" timeline to locate any CLS issues with the webpage.
In the above example one issue was found on the page load, when a "<p>" element (paragraph) is getting slightly moved

When clicking on this red box on the experience timeline we can see more details about it, like how it affects the general score, the size of the element and the distance of the movement.

Whoever it is clear that no CLS issues are caused by the Exit Bee ad as you can see on the photo below:
