Well, I found out that a great way to reduce your bounce rate on your site is to set up your analytics correctly π
I fixed it and the bounce rate of https://rocketcrew.space/ went from 80% to 55%
If you are using Next.js, take a look at this example to set up google analytics

Google analytics is indeed very weird to handle and not that transparent. I had a lot of issues with Coookies & Adblockers etc.
Now I changed to Plausible and it seems much easier ;)
