Most SEO professionals agree that blogging is the best kept SEO secret online. Why is blogging such a great SEO tool? For starters, every time you update your blog with excellent user focused content you invite the search engines back to crawl it. The major search engines really do love fresh content and every blog post is great search bot food. But, and this is even more important, each blog post is a separate web page, which means every time you publish a new blog post you are giving yourself one more opportunity to be found in the search engines.
