Opting out of Google's New tracking Method – FLoC

Luckily, this is quite easy – for now.

Just add the “Permissions-Policy: interest-cohort=()” header in your webserver. This can be done as following:

In Nginx

   add_header Permissions-Policy: interest-cohort=()

That's it!

Edit: In January 2022, Google announced that they would abandon FLOC
