A blog, short for web log, is a specialized site that allows individuals to post articles, stories, news and other forms of content. In many ways, blogs are like public journals where individuals or companies publish original content related to their interests or industry on a regular basis.
Blogs encourage social interaction; readers are encouraged to comment on blogs they like, share them with friends, and subscribe to new updates with a type of RSS Reader.
That's simple. In the world of internet marketing - content is king. Any guess what blogs are great for? Yep! Fresh, new, targeted content related to the keywords you're trying to rank for will not only increase your search rankings, but give your customers a reason to stick around once they get to your site.
