To use LinkedIn to market your business, you need to first set up your business page. LinkedIn has a rather creative method for letting you invite people to follow your page while limiting spam. Each page gets a hundred credits that can be used to invite your LinkedIn contacts to follow your page. But, before you invite anyone at all, it's a good idea to build up some content. This way, when someone receives the invite and goes to your page, there is actually something for them to see.
