PL 38/08: Web traffic to Danish portals

Filed under: Uncategorized — plinius @ 7:28 pm

Many library services are moving to the web.

We need to know how popular and effective these services are. Denmark is a pioneer in this area.The new Danish web index – which started in April –  currently measures the web traffic to sixty-four public libraries and to six national services (web portals).

Traffic to the portals seems relatively low. The traffic to local web sites is denser – per capita – than traffic to resources at the national level.  Below I give some data:

Virtual visits per thousand population in August 2008

Four local libraries

  • Roskilde (80K inhabitants) –   620*
  • Copenhagen (500K) – 410
  • Langeland (14K) – 210
  • Næstved (80K) –  80

*Numbers are given to two significant digits.

National portals and services

*Spørg Olivia is aimed at children in the age group 10-16. I have therefore calculated the ratio with the number of children in this age group (about 410 thousand) as the denominator.
