Where it is useful to advertise a URL (in printed materials, for instance) use the following format: cern.ch/[sitename]

Example: cern.ch/writing-guidelines (note that this resolves to test-static-04.web.cern.ch, which is less easy for new users to remember).

Notes

1. Use lower-case characters
2. Omit the 'http://' or 'https://' unless it is necessary

It may seem obvious, but check that the URL is relevant, and always double-check links are working before publishing. See also: links.
