Social media is a relatively new ranking signal in search engines, but is rapidly becoming more and more important.
Social media is the online communication by which users create their own communities and share ideas and opinions. Social media includes blogs, micro blogs, social networking sites, picture sharing, music sharing and content based communities.
Social media is becoming more important in search engine ranking because when there is a ‘buzz’ around your website search engines consider this to mean that your website is popular and important which increases the chances of it ranking higher in the search engines for your targeted keywords.
