hi chris,
i have this confusion, Let us suppose I have this website and somebody in Canada just wrote 150 words follow link , an external link, to my site
my question is , is that gonna be a referral link or a back link if that website has DA of 70? higher the better
second question: How does that particular post contributes to a referral or a back link I mean does somebody click on it , does somebody reads it ,does somebody shares it, what happens ?
