Why do you think a lot of start up companies and web services have started integrating blogs as their major source of marketing? Because their blog becomes their own media, a way for them to personally connect to their targeted customers. I feel that anybody who offers a service, be it a freelancer or somebody who just sells stuff on ebay needs to have a blog. A blog serves a purpose for you as it becomes your own media. Think about it, if Jeremy from Shoemoney wants to offer service or sell something, do you really think he needs to spend a dime to advertise? I don’t think so. His blog alone will bring him enough customers and again most of them being blogger themselves, if they write about it on their blogs, it becomes viral marketing.
