LinkedIn is a business network that is meant primarily for business professionals as a place to connect with one another and market tier products and services in a (B2B) business to business environment.
It’s a great way to connect and network with business owners and people in a mutually beneficial way!
You can add links to your websites, blogs and other social profiles. You can also set up groups that are similar to Facebook fan pages, and you can also have other recommend your services in exchange for you recommending theirs.
LinkedIn also has a lot of authority on Google and other popular search engines. If you currently have a LinkedIn profile, try doing a search for yourself on Google. There is a good bet that it will show up on the first page of results.
That is authority ranking and you don’t want to miss out on it!
