The clean_page_url event attribute that is added to all events contains the domain name of the website ( origin ) + the page path without any queries or hashes at the end.

Why is it useful?

Did you ever run into issues while analyzing your data when you had lots of landing page urls like the ones below and you were windering how many views the page actually got:

https://domain.com/path?fbclid=874917432348
https://domain.com/path?fbclid=873242524555
https://domain.com/path?msclid=7363738
https://domain.com/path#section

As we all know these urls reference the exact same page but facebook, bing or any other platform may add their own tracking id to the end. You might as well place a link somewhere that points to an exact section of the very same page. All these cases make it hard, time-consuming and tech-savvy to compute total views or total events for a given url.

Computing data for one exact url with this parameter that never contains appended tracking info or hashes is becoming a breeze since you do not have to slice and dice complete urls anymore.
