Performance Cookies

These cookies collect information about how visitors use a website, for instance which pages visitors go to most often, and if they get error messages from web pages. These cookies don’t collect information that identifies a visitor. All information these cookies collect is aggregated and therefore anonymous. It is only used to improve how a website works.

Third Party Cookies

If the host domain for a cookie is different to the one in the browser bar when it was downloaded, then it is a third party cookie.

They are usually placed in a website via scripts or tags added into the web page. Sometimes these scripts will also bring additional functionality to the site, such as enabling content to be shared via social networks.

For example, if you visit a site that has a YouTube video in one of its pages. This has been included by the website owner, using a piece of code provided by YouTube. YouTube will then be able to set cookies through this code, and know that you have watched that video, or even just visited the page the video is in.

Online advertising is the most common use of third party cookies. By adding their tags to a page, which may or may not display adverts, advertisers can track a user (or their device) across many of the websites they visit.

This allows them to build up a 'behavioural profile' of the user, which can then be used to target them with online ads based around their 'calculated' interests.

Use of cookies for this purpose is often seen as intrusive and an invasion of privacy. Such activity is one of the drivers behind the development of new privacy laws, especially the EU Cookie Law.

Session Cookie

Session Cookies are only stored temporarily in the browser's memory, and are destroyed when it is closed down, although they will survive navigating away from the website they came from.

If you have to login to a website every time you open your browser and visit it - then it is using a session cookie to store your login credentials.

Many websites use session cookies for essential site functions, and to make sure pages are sent to the browser as quickly and efficiently as possible.

Secure Cookies

Secure cookies are only transmitted via HTTPS - which you will typically find in the checkout pages of online shopping sites.

This ensures that any data in the cookie will be encrypted as it passes between the website and the browser. As you might imagine – cookies that are used by e-commerce sites to remember credit card details, or manage the transaction process in some way, would normally be secure, but any other cookie might also be made secure.
