  1. What is a cookie?
  2. A cookie is a text file which is stored on your computer or device when you visit a website.  They are generally used to make websites work, or work more efficiently, as well as to provide information about your use of the website, and to display content and advertising that is relevant to you. 
  3. Other technologies operate in a similar way but use different names: for example, pixels, beacons, tags, scripts, social media plug-ins, device fingerprinting techniques, [and SDK tools (which are used on mobile apps)].  In this cookie notice, we use the term “cookie” to refer to all similar technology.  
  4. Why do we use cookies?

We (and our partners, including marketing partners) use cookies for various purposes: to analyse trends, administer the services, remember your preferences, track users’ movements around our website, gather demographic information about our user base as a whole,  enable you to navigate between webpages more efficiently, help us understand how our website is used so we can improve it, [and record information about your visit to help target advertising and to build a profile of you].  The purpose for each cookie we use is set out below.

  • What cookies do we use and how long will they stay on my device?
  • We use four types of cookies: strictly necessary cookies, performance cookies, functionality cookies (including for social media), and advertising cookies.  Each type of cookie has a different purpose.
  • Some cookies are set by us (known as first-party cookies). 
  • Other cookies are set by another organisation’s website (known as third-party cookies).  For third-party cookies, we do not have access or control over these technologies.  We do not tie the information gathered by third parties to our customers’ or users’ personal information.
  • A cookie can either be a session cookie or a persistent cookie.  A session cookie is stored temporarily on your computer or device while you use the website, and is deleted when you close your internet browser.  A persistent cookie remains on your computer or device after you have closed your browser, so we can remember if you have visited our website before or your preferences [or to track your actions across different websites in order to target advertising to you].  Depending on the type of cookie, the period of time the persistent cookie stays on your computer or device is set out below.

Google Analytics   _utma CookieA persistent cookie – remains on a computer, unless it expires or the cookie cache is cleared. It tracks visitors. Metrics associated with the Google __utma cookie include: first visit (unique visit), last visit (returning visit). This also includes Days and Visits to purchase calculations which afford ecommerce websites with data intelligence around purchasing sales funnels.  PersistentGoogle
Google Analytics   _utmb Cookie  & __utmc Cookie

These cookies work in tandem to calculate visit length. Google __utmb cookie demarks the exact arrival time, then Google __utmc registers the precise exit time of the user. Because __utmb counts entrance visits, it is a session cookie, and expires at the end of the session, e.g. when the user leaves the page. A timestamp of 30 minutes must pass before Google cookie __utmc expires. Given__utmc cannot tell if a browser or website session ends. Therefore, if no new page view is recorded in 30 minutes the cookie is expired. This is a standard ‘grace period’ in web analytics. Ominture and WebTrends among many others follow the same procedure.  30 mins from set/update (_utmb) Session duration (_utmc)Google
Google Analytics    _utmz CookieCookie __utmz monitors the HTTP Referrer and notes where a visitor arrived from, with the referrer siloed into type (Search engine (organic or cpc), direct, social and unaccounted). From the HTTP Referrer the   __utmz Cookie also registers, what keyword generated the visit plus geolocation data. In tracking terms this Cookie is perhaps the most important as it will tell you about your traffic and help with conversion information such as what source / medium / keyword to attribute for a Goal Conversion. This Cookie is updated every time data is sent to Google Analytics.  6 monthsGoogle
