Blogs, known for about two seconds as “web logs,” are regularly-updated online journals intended for general public consumption. Blogs are an excellent vehicle for promotion because of how frequently they are updated — regular doses of fresh content are good for attracting both search engine spiders and human readers!
One of the biggest advantages of a blog over a web page is a blog’s capacity for creating conversation between you and your customers. Web page communication all goes one way, from the writer to the reader. Blog communication goes back and forth, with readers responding to the blogger’s postings, and bloggers responding to reader’s comments. A well-written blog can become a popular online hangout, and the more people comment on your postings, the more fresh content you have — and you got it for free!
Another advantage of the blog is that you don’t need any design or technical skills in order to get and keep your blog up and running –your blog host takes care of all the design, coding, uploading, server maintenance, etc. All you have to do is choose your template and start writing.
