Page "Web analytics" Paragraph 87

Here the culprit is the metric of a new visitor.

There is really no such thing as a new visitor when you are considering a web site from an ongoing perspective.

If a visitor makes their first visit on a given day and then returns to the web site on the same day they are both a new visitor and a repeat visitor for that day.

So if we look at them as an individual which are they?

The answer has to be both, so the definition of the metric is at fault.
