Social Media is important because the search engines are starting to view social media as more important than regular websites. The problem is that the social media landscape changes so quickly. The question is which social media to use and in what balance.
In today’s social media world, it is essential to have a Google Plus Page, a Twitter feed, a Facebook Page, a Pinterest presence and a strong Linked-in presence.
Since everyone searches in different ways, you need to have a presence everywhere possible. It isn’t necessary to have to have a strong presence on every social media platform. I recommend that you create a strong presence on one, and then divert other social media into your favored social media, i.e. your LinkedIn page.
