Information collected by BTG

You can visit our site and view most of the content anonymously; however, like many websites, we may collect information from you both by asking specific questions on the site and by permitting you to communicate directly with BTG. In addition, as you navigate through the site, certain information can be passively collected using various technologies. Like most website operators, we track IP addresses, use both session and persistent cookies, and assign internet tags.
A cookie is a small text file that is stored on a user's computer for tracking and record-keeping purposes. We use the following cookies throughout the site:

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 & _utmc

 _utmb – 30 mins
_utmc – End of session

Google Analytics - 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. Omniture 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.

BTG website visitors who want to turn off these cookies can do so by changing their web browser settings. Please see for more information about blocking cookies on your particular web browser.
