I Need SEO Advice from Google Experts

I need SEO advice from Google Experts, a real SEO expert! I need to know how to properly optimize every article I published.  There are over three hundred or more blog post in this blog investmenttotal.com. I need your guidance, your tips and the best advice to boost my organic traffic.

Here’s my problem (kindly solve it). First, when someone search for a keyword “investment total” my blog rank number one on SERPs, and rank number four when someone used the keyword “total investment”. Since my domain name is related to the keyword, that’s why I am ranking higher in SERPs.

When I search for a certain keyword to my post, example my blog post is “how to start investing in stocks”.  The blog post didn’t even get into top 10 on SERPs. What should I do to rank every article I published?
