I have read an article where they've discussed about how helpful does social media in gaining more unique visitors. i read it from here: http://www.7th-media.com/blog/using-...ite-traffic-2/ i just want to share this stuff, since i find this as a very helpful guide for us marketers. i guess social media is one of the best way to fight back from the google penguin updates. so what can you say about it?
