It depends.
Users that do not give consent are users that cannot be tracked (with analytics or media tools).
The notice bounce rate might be impacted by two main notice settings:
- Notice format: web notices can have a sticky banner format or a pop-in format. The bottom sticky banner is more prone to be ignored as it’s not blocking access to the content. The sticky banner combined with a click consent trigger will generally generate more notice bounces than a pop-in banner that can’t be ignored.
- Consent trigger: consent triggers are click, scroll, and navigation. The scroll and navigation consent triggers (not compliant in most EU countries, please review this article) will lower the volume of notice bounces as they are just requiring the user to engage with the website.
Website bounce rate and No Choice rate
A high website bounce rate will automatically impact the no choice rate.
Keep in mind that the notice is displayed to people that have not provided consent. Therefore, it will be mostly shown to new visitors. Media traffic will generally bring new visitors and has high website bounces.
Also, if a visitor bounces on your website without giving consent, it will be considered a no-choice, but you won’t be able to measure it with your analytics tool as the analytics tag can’t be triggered without consent.
For that reason, actual website bounces, the bounces in your analytics tool, and the no choices are three related but different metrics.
