Working in the new media industry I still find it's hard to get people used to measuring online success in terms of 'page impressions' and audience in 'Unique Visitors' (meanings of these below).
I find myself regularly (irritatingly condescendingly) correcting people who talk of 'hits', here's a definition of why hits are dead as a measurement of a web sites success:
Measuring website statistics:
- Page impressions are the number of individual pages that are viewed on your site.
- Visits are the number of times a person or computer IP address is logged as having visited your site, regardless of how many pages the look at or what they do.
- Unique Users/Visitors are all the individual visitors to your site, if they visit more than once it still only counts as the same Unique Visitor of the chosen time period.
