Maybe think about the type of content you produce and whether or not it encourages discussion. The level of engagement on my posts really increased when I started including stuff that inspired discussion.
This post is obviously one that inspired discussion. People are passionate about doing well on Steemit so it was an easy choice. There are 62 comments here including my own. I've also written about mental health and stuff which also inspired a decent amount of discussion.
Being successful in blogging seems to be about getting high levels of engagement on your posts, so simply giving information away isn't always the best approach. The best type of content is material that gets people expressing their own opinions as well.
