As most everyone knows these days in the business world blogging has become one of the tools of the trade. It keeps your established clients informed and brings new prospective clients to your website. A short and simple explanation is in a section of an article I was reading.
The true power of the blog comes from its interactivity with visitors and other blogs. As an author, you can allow your web visitors to comment on your entries, the comments then being published along side or in a separate window of the entry. On your blog, you can keep track of when other blogs reference one of your entries. You can have their references to your site be automatically published on your site. Your website is no longer an island visited by anonymous people only known to you by the page view statistics your web host gives you about your site. Your visitors, at least those who either comment on your blog, or make a comment about your blog on their blog have a name, an email address, a website – an identity. As you find other blogs that you like to read, you link to them on your blog site. And as others find your blog interesting, they link to you as well. All of this helps build a community of those who share a common interest in each other’s content.
One note: It is important if you are utilizing a blog, especially for Search Engine Optimization (SEO) aspects to keep your content fresh!
