program to automated backlinks?

Hi guys, sorry about my English, it's really bad ^^'.

Today I would like to invest more in the linkbuidling theme as it is my weak point. I would like to automate it but I don't know which program you recommend.

I'm looking for something simple or where I have material to know how to do it.
I've heard of these programs:

seo autopilot
GSA Rank

thanks
