Only a few recent posts in newsfeed. A long time between some of the posts.
We need to get you to ramp up your posting frequency. Aim to post at least once per day in your newsfeed and 5-6 stories per day.
You are getting great engagement from your posts. They are very well written. You just need to post more to get to more eyes.
Work on using 25-30 hashtags with each post and consider asking a question with some posts to encourage more comments.
