Help improving a site

I have a website where i've been posting blogs twice a week for a year now. And maintaining site health but it's just not improving. I'm using semrush to track these. Organic traffic went 500 on november and in january it plumped down to 2 digits again, but not in june it's back to 200 visibility is always 8-11% backlinks is not that much too. What improvements should i do or strategy to change. submitted by <a
