Should i build links to my guest posts?

Hello,

I am currently pushing only clean, relevant guest blogs to my money website, but i am wondering, should i build links to those guest posts? and if so; which kind? I am currently top 20 for all my keywords but i have been stuck and would like an extra power push. Or should i build other types of links to my site and if so which kind?

Any feedback is highly appreciated!
