Why is this true?
1) Google your name. Why is it that most likely your LinkedIn profile is the first listing that comes up? At a glance, your LinkedIn profile has the most complete information on you of any of the social networking profile pages.
2) Where can you find professionals that are reported to have an average income over $100,000.00? The average income on LinkedIn is reported to be the highest of any social networks, so you will find buyers that can afford your product.
3) Which Social Network can you find out who has been looking at your profile? On LinkedIn you can easily see who has been searching for you. LinkedIn encourages you to use this method of connecting to other members to engage and exchange information.
So if you have been thinking that Facebook and Twitter are the only games in town, I suggest you reconsider and check out LinkedIn.
