Here are some questions to ask and tools you can use to check the credibility of online information:

Who is the author? If no author is listed, the information doesn’t pass the first sniff test.  If an author is listed, search the name to see the author’s digital footprint. What else has the author written and what has been written about her or him? Are those sources credible?

If it is a news site, does it clearly disclose ts funding sources? Does it acknowledge and correct errors? Does it have a Code of Ethics? An Editorial Independence Policy? (Here are the Terms of Service at NOWCastSA)
