Most of the sites use "click here for/to …" wording. That implies that:

• The user is too stupid to see it is a link (alternatively the webmaster made it impossible to see it is a link)
• The user has and uses a mouse
• The document is not going to be printed (it will look stupid then)
• The webmaster has no imagination
• The webmaster does not care how the site will be indexed by search engines
