[Question] Possible to use cookies to tell if someone has been to the site before or not?

Probably super simple but I can't find anything about it.

Just want to direct new traffic to register and not-new traffic to sign in.

Just a simple yes/no and if yes then a quick link to a guide would be great. thanks
