Would someone mind elaborating on social media and how it pertains to Google rankings? Are you saying a well optimized company facebook page? Or YouTube videos with link to your website? Are these types of links really helping with Google rankings? Or are you just saying these are links to your website that will get your traffic because a site like facebook is so highly visited these days. Appreciate the clarification. And what about Craigslist? I see more and more people posting "questionable" job postings to acquire links to their homepage. Thoughts on this link value welcomed.
