Ich hatte mich (in der Kategorie Web Analytics) auch schon mit Definitionen abgemüht. Nun habe ich von der Web Analytics Association eine klare Definition gefunden der wichtigsten Begriffe gefunden. Zur Zeit nur auf Englisch aber sicher heilsam um Verwirrungen zu vermeiden (und auch im Detail gut gemacht z.B.Unique Visitor ist „filtered for spiders and robots“).
Hier eine Übersicht über die enthaltenen Terme und unten das PDF.
> Page: A page is an analyst definable unit of content.
> Page Views: The number of times a page (an analyst-definable unit of content) was viewed.
> Visits/Sessions: A visit is an interaction, by an individual, with a website consisting of one or more requests for an analyst-definable unit of content (i.e. „page view“). If an individual has not taken another action (typically additional page views) on the site within a specified time period, the visit session will terminate.
> Unique Visitors: The number of inferred individual people (filtered for spiders and robots), within a designated reporting timeframe, with activity consisting of one or more visits to a site. Each individual is counted only once in the unique visitor measure for the reporting period.
