A visitor who has never been to the site since tracking with WebTrends and persistent cookies began.
New visitors are identifiable only on sites that give out persistent cookies. WebTrends identifies visitors as new visitors if they have no site cookie when they arrive, and they are able to accept a cookie for their subsequent page views. If they already have a site cookie when they arrive, they must have been to the site before. In a log file, a new visitor’s first page view has no cookie, but all other page views do.
It’s important to realize that “never been to the site before” can be evaluated only for the time period during which the persistent cookie has been given out. In fact, when a persistent cookie is first implemented, all visitors appear to be first-time visitors.
