I don’t find Facebook or Google + to be particularly valuable for my business (I have a career help web site and I offer career services). Facebook is so scattered in its diverse messaging, it’s hard to find a following there and Google+ just seems too new, too small, too random to be helpful.
By far, I find LinkedIn to be the most useful site to build my business. In fact, I came across this statistical information recently: LinkedIn generates the highest visitor-to-lead conversion rate at 2.60%, 4 times higher than Twitter (.67%) and 7 times better than Facebook (.39%), according to a study of 3,128 business customers of the marketing agency HubSpot.
