What is in a cookie?
A cookie is a simple text file that is stored on your computer or mobile device by a website’s server and only that server will be able to retrieve or read the contents of that cookie. Each cookie is unique to your web browser. It will contain some anonymous information such as a unique identifier and the site name and some digits and numbers. It allows a website to remember things like your preferences or what’s in your shopping basket.
By continuing to browse this site you agree to the use of the below cookies:
Frontend – Session
A session cookie only lasts for the duration of users using the website. A web browser normally deletes session cookies when it quits.
__utma – 1 day cookie
This cookie keeps track of the number of times a visitor has been to the site pertaining to the cookie, when their first visit was, and when their last visit occurred. Google Analytics uses the information from this cookie to calculate things like Days and Visits to purchase.
__utmb & __utmc – 1 day cookie
The B and C cookies are similar, working together to calculate how long a visit takes. __utmb takes a timestamp of the exact moment in time when a visitor enters a site, while __utmc takes a timestamp of the exact moment in time when a visitor leaves a site. __utmb expires at the end of the session. __utmc waits 30 minutes, and then it expires. You see, __utmc has no way of knowing when a user closes their browser or leaves a website, so it waits 30 minutes for another pageview to happen, and if it doesn’t, it expires.
__utmz – 182 day cookie
__utmz keeps track of where the visitor came from, what search engine you used, what link you clicked on, what keyword you used, and where they were in the world when you accessed a website. It expires in 15,768,000 seconds – or, in 6 months. This cookie is how Google Analytics knows to whom and to what source / medium / keyword to assign the credit for a Goal Conversion or an Ecommerce Transaction. __utmz also lets you edit its length with a simple customization to the Google Analytics Tracking code.
