Answer:
We’ve all heard that content is king and that you need to write high-quality content, or now “10x content,” as coined by Rand Fishkin. Ask SEOs what “quality content” is and you’ll receive a lot of varied and opinionated answers. Quality is subjective, and each person views it differently.
Ask SEOs what Google considers to be quality content, and you will get a lot of blank stares. I know because I like to ask this a lot.
The number one answer I get, sadly, is that content should be x number of words, where x is usually 200, 300, 500, 700, 1,000, 1,500, or 2,000. More content does not mean better content. A simple query about the age of an actor can be fully answered in a sentence and doesn’t require their life story and filmography.
Another answer I receive is that the content should be “relevant.” The problem with this is that low-quality pages can be relevant as well.
Other SEOs I’ve asked have given amazingly detailed answers from patents or ideas from machine learning about word2vec, RankBrain, deep learning, count-based methods and predictive methods.
