I am starting my first actually journey to rank SEO and make some money with a CPA site I completely custom designed and coded. I need to get some legitimate traffic and I feel like SEO is the best natural way to get people to start this to get a viral social exchange. I am pinging all of the social media sites I posted this link on. Only to really notice that all social medias like Pinterest have no-follow on. So should I really spend my time building links to these for backlink authority? Not to mention, these links are never going to have tons of upvotes on reddit, or lots of repins. And if they did, it would be with a paid service, nothing that would most likely lead to legit traffic.
