My blog has been ranking for a few years now. I have seen very high and low rankings in page position and domain authority.

I swear by directories. For me, directories are more efficient than backlinks- especially, internal backlinks.
When I check my traffic sources through Blogger, I notice very few links to spam and other offensive sites.

How much does knowing traffic sources affect rankings? Does traffic from social "scanners" hurt. These social scanners I am new to
seem so much better than organic traffic.
