Quill, you're such a dope. :-)

My thoughts on length are much more simple. Google says size matters. Not only does it rank better, but it also converts traffic to dollars better. Neil Patel shows you how to do the math. But if you're writing just to feed the search engines, shame on you.

As @quillfire said, the proper length of an article is no more and no less than the material dictates. I've been writing online since the 1990s, and I've been blogging full-time since 2006. I have over 10,000 blog posts behind me and I've discovered that the key to successful content marketing is to be engaging. Keep it interesting, entertaining, and your audience engaged and they'll burn their dinner reading your content.

Here's something to think about: How long should a fiction story be? Hemingway wrote one in six words - "For sale. Baby shoes. Never worn." A Song of Ice and Fire by George R. R. Martin is seven volumes and over a million words.

How long should yours be? Only you can answer.
