Should I get back links from my own domain blog

Hello,

I have a domain (ex: domain.com). I also have a blog for this domain, domain.com/blog/. I create one article that relates to my domain every two weeks and post it on this blog. On each article, I promote 3 links back to my own domain.com.

do you think it is a good idea to get back links from this way?
Should I keep promoting the same keywords over and over?

Thanks.
