Some details:

  • __utmz stores where a visitor came from (search engine, search keyword, link)
  • __utma stores each user's amount of visits, and the time of the first visit, the previous visit, and the current visit (presumably partly for double checking of this information).
  • __utmb and __utmc are used to check approximately how long you stay on a site: when a visit starts, and approximately ends (c expires quickly). If you look at cookie state changes (e.g. using firecookie), you will see these change regularly.
  • __utmv is used for user-custom variables in Analytics
