Keep it Simple
The secret to good teaching / training is to keep it simple.
This does not mean that you simplify things as you might to a 5 year old but it does mean that you explain using words and terms that the person you are speaking to will understand.
Your Blog Posts
You are most likely using a SEO plug in to help you rank well with your blog posts such as SEO Yoast. These plug ins will often tell you how readable your post is to your audience. Interestingly they rank you higher when the reading age is that of a 12 year old rather than an experienced adult.
Who is your blog post for? Even if it is for a well educated and technically minded audience it is still best to use and explain terms for a wider audience if you want wider readership.
For most us us looking to make money from affiliate marketing the 12 year old reading ability is a good one to aim for.
