What are cookies?
We may use information obtained from cookies or similar technology. Cookies are text files containing small amounts of information which we download onto your computer or device when you visit our website. Therefore, when we refer to "you" in this section we mean your computer. We can recognise these cookies on subsequent visits and they allow us to remember you.
Cookies come in many forms. We have set out below the main types and categories of cookies that are used. This section refers to all types and categories of cookies and not just those we use on our website.
First and third-party cookies - whether a cookie is first-party or third-party refers to the domain placing the cookie. First-party cookies are those set by a website that is being visited by the user, the website displayed in the URL window e.g. www.wpp.com. Third-Party cookies are cookies that are set by a domain other than that of the website being visited by the user. If a user visits a website and another entity sets a cookie through that website this would be a third-party cookie.
Persistent cookies – these cookies remain on a user's device for the period of time specified in the cookie. They are activated each time that the user visits the website that created that particular cookie.
Session cookie – these cookies allow website operators to link the actions of a user during a browser session. A browser session starts when a user opens the browser window and finishes when they close the browser window. Session cookies are created temporarily. Once you close the browser, all session cookies are deleted.
These cookies are essential in order to enable you to move around the website and use its features, such as accessing secure areas of the website. Without these cookies certain services you have asked for cannot be provided. e.g. the ASP.NET cookie.
These cookies collect information about how users use a website, for instance which pages users 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. They are only used to improve how the website works.
These cookies allow the website to remember choices you make and provide enhanced, more personal features. For instance, e.g. the AddThis cookie. The AddThis cookie provides ‘share this page’ functionality, where a user can email a link from a report or a page to their friends. They may also be used to help provide services you have asked for such as watching a video or commenting on a blog. The information these cookies collect may be anonymised and they cannot track your browsing activity to other websites.
These cookies are used to deliver adverts more relevant to you and your interests. They are also used to limit the number of times you see an advertisement as well as help measure the effectiveness of the advertising campaign. They are usually placed by advertising networks with the website operator's permission. They remember that you have visited a website and this information is shared with other organisation such as advertisers. Quite often targeting or advertising cookies will be linked to site functionality provided by the other organisation.
