I'm using GSA SER to do some backlinking but I'm hearing that social signals is also very important for making things look natural. But how would I go about doing this? Would social signals simply just be the "Social Media" and "Social Bookmarking" within GSA? I heard stuff about Facebook/Twitter/Pinterest, but what exactly do I do if my Twitter/Pinterest accounts have no followers? Do i just tweet and pin on my own accounts and that's it? And as for facebook, do I just share on my own profile? Or start spamming groups?
