#Technology: Odd domain names generally equal odd and rarely truthful news.

 Professor Melissa Zimdars

"Not all of these sources are always or inherently problematic, neither are all of them fake or false," Zimdars notes in the document. "... They should be considered in conjunction with other news/info sources due to their tendency to rely on clickbait headlines or Facebook descriptions, etc."

Farther down, she gives tips for how people can identify potentially fake news. Things like strange domain names, unusual domain extensions, and using ALL CAPS should be warning signs. And make sure to look for who else is reporting the news: "Sometimes lack of coverage is the result of corporate media bias and other factors, but there should typically be more than one source reporting on a topic or event."

Both Facebook and Google have recently announced they will take steps to block fake news sites from accessing their advertising services.
