Hello ! I have 2m articles ( 95+% unique, readable, not spinned or generated by program) , split in 20 domains. Like 80% of them are indexed in google, but the traffic is kinda low, only 500-800 UV/day. Those articles are fresh indexed, they still don't have rank or anything. From my previous exp., I can tell you that ranking with on-page SEO and social signals ONLY ( no backlinks ) is possible. So here my question: - How to make social signals to so much content ? - Will traffic increase, when articles/site get older ? ( asking, because don't have idea what happens if you write original content and do nothing, even social shares ) Please, I need your ideas, so I can fix this issue and scale up to 100m articles to the end of this year. regards !
