In my opinion, Neil's writing style is the future of SEO content.
People aren't wanting to read novels online. They want clear, punchy text. It's just EASIER on the eyes. I've seen people that put 400 words in a single paragraph, with two or three sentences total. What the fuck was the article about? I dont know. tl;dr
By breaking the written content into smaller groups, he is able to help with his bounce rate because he doesn't scare people off. I'll admit, I have fallen into a couple of his 6,000 word posts, and I end up reading the entire thing, because ... it just happened!
One of the biggest advantages, is the one most overlooked. The length of his posts are capable of ranking highly for hundreds and sometimes thousands of keywords! Why? Because
there are more words on that single url that can be picked up by google. Example, he will have a 4 or 5k article on SEO. If he MAXIMIZES his usage of keywords and LSI keywords, he is able to rank for a MASSIVE list of relevant keywords. This in effect, also lets you link to the article for more than just the single keyword, and have actual substance behind the LSI, rather than just a simple mention.
The article is then building a shitload of authority, because the bounce rate is low, and you have a shitload of links, and shares.
It makes brilliant sense, and it's one of the things that influenced my writing service to contain a "minimum" writing length.
When I write, I will use
hemingwayapp.com. It will show you the reading level of your articles. I try to keep it around 6th-9th personally. Depending on what I'm writing about, I've gone down as low as 4th grade. But that's because I was writing about video games!
I like to keep the sentences short, as if I were writing a speech. Commas and periods in my mind, are places where you can stop and take a breath before continuing. If you're a writer, or trying to learn, I would first try to write like this.
I'm no scholar, but I'm no idiot. Take my advice with a disclaimer: It's all just my opinion based upon my own experiences and critical reasoning of the concepts he presents.
