How the cookies crumble

Cookies are small files that allow a website to recognise and track users. The Information Commissioner's Office (ICO) groups them into three overlapping types:

Session cookies

These are files that allow a site to link the actions of a visitor during a single browser session. They are not stored long term and are considered "less privacy intrusive" than persistent cookies.

Persistent cookies

These remain on a user's device between sessions and allow one or several sites to remember details about the visitor. They may be used to target advertising or to avoid having to provide a password each visit.

First and third-party cookies

First-party cookies are set by the site being visited. They are typically used to study how people navigate a site.

Third-party cookies are issued by a different server to that of the domain being visited. They could be used, for example, to trigger a banner advert based on the visitor's viewing habits.
