All British Rowing cookies will have a domain of either www.britishrowing.org or .britishrowing.org
A persistent cookie that remains on a computer, unless it expires or the cookie cache is cleared. It tracks visitors on the British Rowing website.
__utmb Cookie & __utmc Cookies
These cookies work in tandem to calculate visit length for Google Analytics. 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.
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, and enables British Rowing to see the referring links and sites that have led people to the British Rowing website
Google __utmv Cookie lasts "forever". It is a persistant cookie. It is used for segmentation, data experimentation and the __utmv cookie works hand in hand with the __utmz cookie to improve cookie targeting capabilities.
