What are good sources to cite?
Importance of using good sources
Using proper sources build audience trust in a reader. They allow readers to verify what an author has to say and delve more deeply into the topic with ease. Incorrectly cited or untrustworthy sources cause readers to question the validity of your claims.
Sources to Avoid[1]
The hallmarks of a bad site are unreliable authors with unverifiable credentials. Their content is often driven by the average internet user and cannot be trusted. Some examples of such pages are Blogs, Personal Websites, and Wikipedia.
Peer-Reviewed
A peer-reviewed article is one that is "read by subject experts ("peers" of the author) before they are published in a journal."[2]
