b) How Rock UK uses cookies most websites use cookies to capture statistics about visitor viewing habits on their websites. Rock UK uses tools such as Google Analytics to capture data on which pages are most often viewed, how long you spend on a page and which pages are most useful for example. This helps us improve your viewing or remove pages that are less useful.

Cookies we use

Google Analytics

We use Google Analytics tracking cookies to collect anonymous traffic data about your use of this website. This information is stored by Google and is subject to their privacy policy, which can be viewed here: Google Analytics collects information such as pages you visit on this site, the browser and operating system you use and time spent viewing pages. The purpose of this information is to help us improve the site for future visitors.

The following cookies are set by Google Analytics:

__utma Cookie
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.

__utmz Cookie
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.

__utmv Cookie
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.


The Rock UK website uses a Twitter feed to keep our visitors up to date with what we are tweeting about. Twitter creates two cookies that are placed on your machine. 

The cookie “guest_id”
This cookie is used to to see if you already have a twitter account. If you do not have a twitter account then twitter will assign you a unique code to track your visit to the Twitter feed. This cookie will expire in two years after creation. 

The cookie “k”
In order to display our tweets on our website, we need to use the official Twitter API. This API creates a cookie on your machine called “k”. This cookie will expire in one week after creation.
