Detectives need to figure out why the author wrote the site - what was their purpose: to sell something, to teach you something, to be entertaining, or to convince you to help support their cause. Is the information biased or incomplete?
Check out the URL of the website (that's the address at the top that begins with: http://****). The address will include a domain name that will help you learn who is sponsoring the site and what kind of an organization they might be.
Here are the most common domain names you'll see:
.com - commercial organizations (they may be trying to sell you something. However, NationalGeographic.com does sell items but is also a reliable organization with accurate information)
.org - most of these are non-profit organizations, but not always
.edu - educational institutions - requires registration
.gov - government - requires registration
.net - organizations involved in internet services - original purpose but not anymore
.int - international organizations
.k12 - k-12 school districts - requires registration
.kids - site developed for kids - usually elementary age
