This article explains how you can start collecting real user Core Web Vitals data on your website.

Generate a RUM snippet
Navigate to the project RUM tab and click Get Started.
Install the DebugBear RUM snippet on your website
Your unique tracking code has now been generated and you can install it on your website.
Installing in an HTML template
The best way to install the DebugBear snippet is to insert it into the HTML
<head> tag on your website. This may be possible through an admin UI on your website, or a developer can help you do this.
Installing via tag manager
It is also possible to install the DebugBear snippet using a tag manager like Google Tag Manager.
The limitation here is that the snippet will be loaded later than if it was embedded directly in the document HTML. This can mean that some very short user experiences are missed. For example, think of a user on a slow connection and who waits 5 seconds for page content to show up and 10 seconds before Google analytics loads. If they navigate after 7 seconds then their poor experience will not be recorded.

The DebugBear snippet is loaded asynchronously and currently takes less than 10 kilobytes to download. It should not have a significant impact on your page speed as the script is small and the browser will prioritize more important resources.
