Google Analytics -utma
Utma is the main way through which Google Analytics tracks unique visitors. The cookie stores the date, time of the first visit, and a visitor's ID. Also, this cookie stores information on the number of visits they've made. The -utma cookie can last for up to 2 years. However, you can customise the expiration time in the tracking code.
Google Analytics -utmb
-utmb is a type of cookie that tells Google Analytics whether a visit has timed out and also how far the visit went. It also stores information of the start time of the visitor's current visit as well as the number of page views in the current visit. This persistent cookie expires in less than an hour. But, each page visit refreshes it.
Google Analytics -utmc
Once Browser Closes
This is the only session cookie used by Google Analytics. The -utmc cookie registers that the visit ended once the user closed the browser.
Google Analytics -utmv
Google Analytics -utmz
This cookie contains all the information on the source of traffic for the current visit, the cookie doesn't change if no traffic source information is found for the current visit. This cookie doesn't contain historical information for previous sources. It's the way Google Analytics attributes visit information, such as transactions and conversions to a traffic source. Being a persistent cookie means it expires in 6 months. The only way to refresh it is to change the traffic source.
