Targeting Cookies (Google Analytics)
|__utma||This cookie is typically written to the browser on the first visit to my website. If the cookie has been deleted by the user and they return to my website, a new __utma cookie is written with a different unique ID. This cookie is used to determine unique visitors to my website 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.||2 years from set/update.|
|__utmb||This cookie is used to establish and continue a user session on my website. When a user views a page on my website, 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 my website, 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. This cookie expires when a user pauses on a page on my website for longer than 30 minutes.||30 minutes from set/update.|
|__utmc||Set for interoperability with urchin.js. Historically, this cookie operated in conjunction with the __utmb cookie to determine whether the user was in a new session/visit.||End of browser session|
|__utmz||This cookie stores the type of referral used by the visitor to reach my website, whether via a direct method, a referring link, a website search, or a campaign such as an ad or an email link. It is essentially used to calculate search engine traffic, ad campaigns and page navigation within my website. The cookie is updated with each page view on my website.||6 months from set/update.|
