What are third-party cookies?
Third-party cookies are cookies that are placed on a user’s device by a website other than the one they are currently visiting. They are usually used by advertising networks to track what users do across multiple websites. For example, if they visit one site and then visit another site that has an advertisement from the same advertising network, the ad can follow them from site to site.
Third-party cookies can include cookies set by services such as analytics providers and social media platforms.
