When it comes to the length of an article, you can shoot the moon. But remember that different lengths are good for different purposes. #TWSS
Super-short posts are best for generating discussion, or as a social media post. Regardless of how long your blog post is, you'll be using your social media channels to share it. Therefore, if your post is SO short that it doesn't pay itself off when your audience clicks-through to read it, then it might be a letdown. Therefore, short posts rarely get many shares on social media, and they’re horrible for SEO. But if you want a lot of comments, then write short posts.
This is pretty standard blogging and email length, and it's often recommended by many “expert” bloggers. Take that for what it's worth. Don’t forget to link to sources, alt-tag your images, and end with a question to start engagement.
BLOGGER TIP: You should know the age of your readers. On average, the younger your audience is, the shorter the content.
If “School House Rock” had a song called "Groovin' to Blog Town," it would use this as the magic number for professional journalism — especially online magazines, and newspapers.
From this point forward, you might get fewer comments at this length. Why? Because people are lazy and that's a lot of words read. BUT — you’ll get a lot more shares. Why? Because when you share longer articles, you look smarter. (I never said this was sexy.) You'll also find that longer articles are better at solving problems simply because the author has taken more time to be granular about the subject matter.
The highest-ranking SEO ranked articles on Google are 2,500 words or more. This is often because you justify, analyze, or debate your subject matter to the point that the search engine perceives you as having more authority on the subject compared a brief post.
