I'm not their consumer but
Arguably Fox and Breitbart are amongst the best at selling stories with minimal truthful content. They have quite the audience, for one thing.
One "good" bad trick is to report opinion, what's been said by the President or the White House or the candidate running in Springfield. On the other side... well, the other side really, isn't hugely different, politically. Like homo sapiens and chimpanzees, they are 99% the same. What's really different is other countries. Therefore also what's really scary. I don't think I see a lot of partisan content from the other side, except for someone who keeps posting a list of Republican office holders who are child molesters. And I don't know which cases are accurately stated but I assume that those who are known to be child molesters are the ones that we don't have to worry about. Anyway, the point I was going for is that a "news" site whose actual business is transmitting partisan statements from partisan third parties is technically lying only in calling this stuff "news". Oh, and in the words "Fair and balanced." And "Most watched. Most trusted." Though... if you don't "trust" them, then why watch, so they must be at around 99%.
