Advice Needed - Blog Growth

My blog is going really well. Last august it was getting 3000 monthly visits, and now it’s up to 45k monthly visits.

I’ve basically been writing blogs non stop since august - five per week. Average of 1k words per blog.

I use surfer to write them, and add internal links to pages I want to see grow to the top of google. I’ve been adding some backlinks here and there to certain pages - about 20 backlinks per month.

My question is, is there anything else I should be doing? I don’t want to lose this momentum. What I’ve been doing is obviously working, but I don’t want to be caught blindsided by something I’m not thinking about and lose the traffic.
