So I am in the process of creating a blog. While I am still building my blog, I want to start to create an audience which later I can market when my blog is finished and have enough content. So I started building up my G+ profile using indianbill's method here. Basically, indianbill's method is create a g+ profile -> search video related to your niche -> look for people who comment in that video -> follow them in g+ in the hopes that they will follow you back. I have someone who works for me and can do repetitive task so I gave him the task of following people on G+. My question is there any method like this that I can apply to build up my facebook page likes? I don't care if it's daunting/repetitive task as I have someone who can do this for me. I tried looking into fb pages related to my niche but I can't see any method to invite them to my facebook page. Hope someone can give me some advice.
