The term “cookie banner” refers to a banner, or splash page, deployed on a website to inform visitors that the website uses cookies, and other online tracking technologies. Some cookie banners also give website visitors choices with respect to whether tracking technologies are, or are not, used, including via cookie “opt-in” or “opt-out” user controls.
