Some sites want u to believe in lies, perversions and hatred: they create false histories and deny facts; they spread bias and misinformation as if it were true. Others will try to con information out of u. Double checking info u find online is always smart. There are billions of sites out there, and not everybody knows what they're talking about.
This site has a set of guidelines for checking online info
Double Checking Online Info...
Check the domain name
Domain names can tell u info about the type of site it is, although even those can be deceptive.
Check if the site is associated with any other?
What kind of sites does a site link to? There is an official-looking Martin Luther King site on the web which links to white supremacist groups. This is a sure sign that most of the "historical" info on there is biased and motivated by racial hatred.
