Linktree is a social media site that gives you a simple web page with all your links to your actual social media sites. This way, you can provide one link to your fans, taking up less space in a profile, then fans can pick and choose to follow on whichever services they prefer.

Usually, it’ll be something like instagram, onlyfans, fansly; maybe some others like snapchat or kik. I think sometimes music artists use Linktree sites too, ie completely SFW, but primarily they exist for NSFW content creators.
