I've invested most of my time with Instagram & have gotten pretty comfortable with growing a page. I wonder if any of the strategies from Instagram (or Twitter, for that matter) are applicable on Facebook? For instance, on IG I would find authority pages in my niche with good engagement, scrape their users & then do the follow / unfollow method. I know there really isn't a follow / unfollow method on Facebook, but say I had a list of 25 - 30 authority accounts in my niche - how best to leverage them? Scrape the users & send messages? Tag them in photos? ??? Aside from inviting people who've liked my posts, I'm having a hard time wrapping my head around other growth strategies on FB. Posting to groups hasn't been very effective for me for some reason.
