Hi fellow BHWers, I've noticed some social media panels offering FB shares and Twitter Retweets for like $2/1000. May I know the difference between these social shares and those that are offered in the marketplace? Because from what I see in the marketplace, social signals cost a lot more. For example, a package that consists of say, 50 FB, Twitter, Google+ shares costs about $10. But then if I were to purchase from social media panels, I could probably get 1000 FB, Twitter, and Google+ shares for $10. So what's the difference? Is it because the packages are real users?
