Strategies for determining how reliable a webpage’s info is:
Domain – .gov and .edu tend to be more reliable than .com and .net
Grammar/Spelling – if the grammar and/or spelling are often poor or incorrect, there is a high likelihood that the site is not reliable.
Photos – if there are no photos to support a seemingly impossible story, it is probably false. If the photos look photoshopped, they probably are.
