Using social networks to socialize is one of the most popular ways to increase the amount of traffic that one gets to a web site.  There is a certain amount of pride and fulfillment when you look at the number of people who have visited your site OR if you get business all because you put a little bit of effort into networking on the web.  There are a lot of people out there who make fun of social networks such as myspace and facebook.  However, the truth is that these two sites are great examples of social networking at its best.  There is nothing that you can’t hold against these sites when it comes to the amount of traffic that is generated.  Many businesses are looking for ways to legitimately join social networking sites like these.  For SEO companies, it is difficult because many people view SEO companies as being somewhat "spammy", therefore their information will be more difficult to try to pick up.
