Promoting a business on social networks is basically a given these days. Depending on the type of company, one social network over another may be better. It seems that Twitter is universally applicable to a wide range of businesses eager to establish an online presence; it's easy to use and control and maintain. Plus, it seems to have the least propensity for abuse.

Facebook, on the other hand, can be a bit more touchy-feely and personal, most likely due to the fact that people associate it with sharing more personal life details.

On the other hand, there's the oft-overlooked Google + which now, according to some new data, might be instrumental in driving site traffic. Thanks to this econsultancy article, I was directed to a study from Searchmetrics, which examined what makes well-positioned pages in Google soar. The team looked at a massive number of links to see why they were placed high.
