How we use cookies
We use cookies in several places – we’ve listed each of them below with more details about why we use them and how long they will last.
Measuring website usage (Google Analytics)
Google Analytics tracks information about which pages you visit, how long you are on the site, how you got here and what you click on. Personal information such as your name or address is not collected so this information cannot be used to identify who you are. More information about Google Analytics cookies can be seen at developers.google.com/analytics/resources/concepts/gaConceptsCookies
The following cookies are set by Google Analytics:
| Name | Description | Typical Content | Expires |
|---|---|---|---|
| _utma | This cookie is typically written to the browser upon the first visit to your site from that web browser. If the cookie has been deleted by the browser operator, and the browser subsequently visits your site, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to your site and it is updated with each page view. Additionally, this cookie is provided with a unique ID that Google Analytics uses to ensure both the validity and accessibility of the cookie as an extra security measure. | randomly generated number | 2 years |
| _utmb | This cookie is used to establish and continue a user session with your site. When a user views a page on your site, the Google Analytics code attempts to update this cookie. If it does not find the cookie, a new one is written and a new session is established. Each time a user visits a different page on your site, this cookie is updated to expire in 30 minutes, thus continuing a single session for as long as user activity continues within 30-minute intervals. | randomly generated number | 30 minutes |
| _utmc | The Google Analytics tracking for ga.js uses two cookies to establish a session. If either of these two cookies are absent, further activity by the user initiates the start of a new session. | randomly generated number | when you close your browser |
| _utmx | You can use Google Analytics with Google Website Optimizer (GWO), which is a tool that helps determine the most effective design for your site. When a website optimizer script executes on your page, a _utmx cookie is written to the browser and its value is sent to Google Analytics. | randomly generated number | 2 years |
| _utmz | This cookie stores the type of referral used by the visitor to reach your site, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is used to calculate search engine traffic, ad campaigns and page navigation within your own site. The cookie is updated with each page view to your site. | randomly generated number and information on how the site was reached (e.g. direct or via a link, organic search or paid search) | 6 months |
