Cookie Policy



By using this website, you are consenting to our use of cookies and other tracking technology in accordance with this Cookie Policy.

A cookie is a data file, which often includes a unique identifier, that is sent to your browser from a web server and is then stored on the hard drive of the device you are using to browse the website. Each website you visit can send its own cookie to your browser if your browser’s preferences allow it.

We use Google Analytics to track the use of this website using their cookies.

Google Analytics sets first-party cookies via a piece of JavaScript code which is added to every page that we need to track. Google Analytics sets four cookies automatically, which are the only cookies deployed, and a fifth via opt-in (this relates to sharing information about the traffic generated with Google).

As this campaign runs both globally, we have adopted using the following cookies:


__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).


__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.


  __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 tells us about traffic and helps with conversion information such as what source / medium / keyword to attribute for a Goal Conversion (in this case an appointment download).


__utmv Cookie

Google __utmv Cookie lasts "forever". It is a persistent cookie. It is used for segmentation, data experimentation and the __utmv works hand in hand with the   __utmz cookie to improve cookie targeting capabilities.
