A cookie is a small file of letters and numbers that we store on your browser or the hard drive of your computer if you agree. Cookies contain information that is transferred to your computer's hard drive.
We use the following cookies:
- Strictly necessary cookies. These are cookies that are required for the operation of our website. They include, for example, cookies that enable you to log into secure areas of our website, use a shopping cart or make use of e-billing services.
- Analytical/performance cookies. They allow us to recognise and count the number of visitors and to see how visitors move around our website when they are using it. This helps us to improve the way our website works, for example, by ensuring that users are finding what they are looking for easily.
- Functionality cookies. These are used to recognise you when you return to our website. This enables us to personalise our content for you, greet you by name and remember your preferences.
- Targeting cookies. These cookies record your visit to our website, the pages you have visited and the links you have followed. We will use this information to make our website and the advertising displayed on it more relevant to your interests. We may also share this information with third parties for this purpose.
You can find more information about the individual cookies we use and the purposes for which we use them in the table below:
A 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.
__utmb & __utmc
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.
Cookie __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.
This cookie lasts six months. 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.
Google __utmv Cookie lasts "forever". It is a persistant cookie. It is used for segmentation, data experimentation and the __utmv works hand in hand with the __utmz cookie to improve cookie targeting capabilities.
You block cookies by activating the setting on your browser that allows you to refuse the setting of all or some cookies. However, if you use your browser settings to block all cookies (including essential cookies) you may not be able to access all or parts of our website.
Except for essential cookies, all cookies will expire after 30 mins from set/update.
