How can you tell whether you're looking at a good source or a bad one? Here are some tips:
Look at the name:
Take a look at the web address. What is the domain?
Typically .edu and .gov websites will have stricter guidelines about what can be published and by whom.
Find the contact information:
Be wary of websites with no way of contacting the creators.
Reputable authors love to be recognized for their work finding and synthesizing information for publication. Works should include the author or organization responsible for creation.
Look for sources:
Good researchers cite their sources (even in informal writing).
Look for links embedded in their post, mentions of the source by name, or formal footnotes/works cited. This gives you the opportunity to read the original material and see if you come to the same conclusions!
