TLDR created with https://tldrthis.com/
Privacy regulations such as the GDPR say that you need to seek permission from your website visitors before tracking them.
Most GDPR consent banner implementations are deliberately engineered to be difficult to use and are full of dark patterns that are illegal according to the law.
I wanted to find out how many visitors would engage with a GDPR banner if it were implemented properly and how many would grant consent to their information being collected and shared.
If you implement a proper GDPR consent banner, a vast majority of visitors will most probably decline to give you consent.
And I wouldn’t be surprised, if those 9% just “consented” out of habit (which would hardly count as legal consent either, as you have to ensure your users make an informed decision).
I’m not terribly worried about the ad industry or the web, though. Non-personalized ads will in most cases be just as relevant as personalized ads, since most webpages are single-topic, too, so that topic will be relevant to a visitor.
The only real “loss” the ad industry has, is that there’s less metrics to look at and feel good about.
