Difference between Bounce rate (web analytics) and No Choice rate (CMP analytics).

Although these two terms are semantically very similar, they are actually different. In this article, we will give you all the information you need to differentiate the Bounce rate and the No Choice rate.


Let's take an example!

A visitor X comes two times to your website's homepage. Each time he leaves, but on his third attendance, he finally consents. All of this within 30 minutes:

  • The Bounce Rate is 0% for the analytics platform: all pages were viewed in 30 minutes, which means only one session. 
  • The No Choice Rate is 66% for the CMP: because 3 notices have been displayed with 2 "No Choice". 

👉The No Choice rate is related to the consent notice and the user's behavior. That's why the Consent Rate is described as "event-based". Here, the behavior is the event.

👉The Bounce Rate only concerns the session, without taking into account the user behavior (or non-behavior) on the pages.  

  • This example is also explained in a short video:


To summarize the difference between Bounce Rate and No Choice Rate:
