Link building is an essential tool for SEO, and using social networks and other social media can be a fun way to build links. Using popular social networks such as Myspace and Facebook allow a website owner to connect with relevant consumers or business owners and presto: increase traffic to a website by suggesting a specific link (yours) to check out!
Millions of computer users spend a majority of their internet time on social networks including Myspace and Facebook. Having a Myspace profile allows is another way for a company to be found outside of major search engines. A Myspace or Facebook profile make a website accessible to target audiences just by "being there".
Link building through social networks, such as Myspace, is very simple. Having a link posted on a profile is just the start. Joining groups and forums relevant to a website is an essential way to manually post links where you want them (search engines love it!), and to boost target traffic to your website.
Aside from the major social networking sites, like Myspace and Facebook, there are relevant social networks for nearly anything. For example, a website devoted to providing work opportunites for telecommuters may benefit from a social network like CafeMom: a social network for mothers. Consider the number of stay at home moms who either are or would like to be a work at home mom.
Using link building on social networks is not just SEO friendly because the major search engines approve, it is an effective way to reach a target market in a "real" way.
Link building through social network and social media (think Yourtube) profiles, forum posts and group messages are a genuinely effective way to promote a webite and boost SEO. The best part is, by joining relevant groups and forums an individual may also learn a thing or two!
