Why should I improve my post’s copy length?

Unfortunately, there is no correlation between writing a lot and more often and getting more traffic. This depends on many different factors, such as your audience, whether the subject is more or less interesting, and so on. Therefore, there is no universal length to follow.

However, depending on your audience and your writing habits, it is possible to set a minimum length you want your posts have. For this, just visit Nelio Content’s Settings and change the length of Post Length input value in the Content tab:

Quality tab within the settings page of Nelio Content.
Quality tab within the settings page of Nelio Content.

According to the value you indicate, Nelio Content counts the words in your posts and displays information about this in the Publish box when editing a post in WordPress:

Post Quality Analysis
Nelio Content analyzes the quality of your post in a non-disruptive manner.
