How are A/B tests for non-logged-in users doing these days with all the cookie banners, privacy and ad blockers etc. Is this stuff still working even?

Yes, but it is _rough_. What actually hurts is "browse on mobile, buy on desktop" type behavior.

Still worth doing, but you end up needing more black magic than you'd like (IP-based assignment, Ad Network-sourced assignment, CDN proxies for Analytics tools, etc).

Working on a separate post about that.
