It's all about traffic, if you don't have people "eye-balling" your Web sites, blogs, Web pages, or advertisements then you have no potential customers. One of the main concepts of online marketing is building back links.
Backlinks are links from other Web sites that point back to your blogs, Web site, or other content. Search engines love back links because that help the search engines to see popularity and authority for a given site, and this helps your blog or Web site climb in the search ranking pages for any given search engine, especially with search engines like Google, Yahoo, and MSN.
Of course getting people to your content is only half the battle.

Once you get them there you have to "convert them," Rather, get the visitor to join, subscribe, become regular returning visitors, or purchase whatever it is your trying to share or sale. Converting gets into an entirely different subject called Copy Writing, which we'll get into in another article for the future. I've compiled a comprehensive list of free ways to market your content.
