Social Media sites are where people post links to information they feel is relevant or vote for or comment on this information, such as articles and blogs. Anyone can browse and look at content while members of the site may post and comment, but anyone can see or comment without having to be invited by another individual.

A good social media optimization plan would include seeding these mediums with information and relevant links to content. Building a network of ‘friends’ and posting other relevant information consistently. You would not just post your own content but content that is relevant to your business or industry. Be active and vocal, comment on items of interest and be an active member of the community.
