Because:

23. Evaluation contd.
 Is it someone’s personal page?
Look for personal name following a tilde(~) or percentage sign (%)
 Is the server commercial? e.g. geocities.com
 What type of domain does it come from?
( educational, non-profit, commercial, government etc.)
Look the domain extension: .gov, .edu., .mil, .org
 Is it current and updated?
Look for last updated
 What are the author’s credentials on this subject?
August 23, 2009

24. Evaluation contd.
 Quality information
Look for indicators such as links, related links, reference whether
scholarly or not.
 Use www.alexa.com ( web information company)
( type URL in the search box)

to the page and others
