Literally described in one of the links.

You can use a cookie for that. If it's for a logged-in user, you can store that in the user profile.
> Please tell me the consensus and guideline on what "legitimate purposes" are.
Text in one of the links literally contains a link to further reading on legitimate interest.
> And most of all, please tell me the consensus and guideline for cookie banners and popups
Literally described in both links.
Once again. It's painfully clear that you never bothered to read and understand anything about the law in the past 6 years. Your clueless questions about "why does gdpr and europa sites have cookie banners" only serve as further proof.
The https://gdpr.eu/ website is not official. Its description of "analytics cookies" cannot be found anywhere in the actual GDPR & Co regulations.
> You can use a cookie for that.
Use a cookie to store the literal "No cookies" preference? Great example of the contradictory and irrational text of the GDPR.
> Text in one of the links literally contains a link to further reading on legitimate interest.
More vague and contradictory BS.
> Literally described in both links.
Too bad that description is not actually valid and if you'll actually check the GDPR text (not the non-official gdpr.eu website) you'll find no such descriptions.
Moreover, the cookie banner on both websites is actually illegal under GDPR. Check out https://ico.org.uk/ for a correct (but horrifying) implementation.
You are correct, I am not an every-day GDPR expert. I only encounter it when implementing on various websites and there only for analytics - no ads or anything more.
But its requirements were always for the worse. Because of its vague and contradictory definitions everybody (including me) adopted the safest implementation and thus the current web of cookie banners and popups was born. I hope you are happy with it, it solves nothing but it makes everybody's life worse.
Please tell me the consensus and guideline on how to store the rejection for using cookies so I don't ask the website visitor every time he visits.
Please tell me the consensus and guideline on what "legitimate purposes" are. With examples per industry please.
And most of all, please tell me the consensus and guideline for cookie banners and popups, considering they are used on the EU's websites themselves.
