Cookies are small files which websites store on your computer and which contain various types of information about your visit to a website. They are not viruses or malicious software but they are generally aimed at providing you with a good experience when browsing a site by, for example, remembering your preferences so that you do not need to reset them every time you visit the website.
Although cookies do not normally contain information about you personally they can record information about how you browse the internet. They can therefore be used by websites to advertise goods and services which, based on your browsing history, are similar to goods and services which you have previously searched online. This is why some users reject or delete cookies.
Cookies normally expire after a length of time which can vary from a few minutes to more than a year. Some cookies are ‘session cookies’ which are deleted when you close your internet browser or after a period of inactivity. Others are ‘persistent cookies’ which remain on your computer until their expiration date.
Our website uses the following cookies
If you are a member then a session cookie is used to enable a quick integration with the NOD system via a autologin function between our Drupal site and NOD.
The following cookies are set by Google Analytics:
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 Cookie & __utmc Cookies
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.
