Blogging is very popular right now. And having a business weblog that provides good information for your customers while being timely and fun can add a new dimension to your Web site.
Blogs are a powerful tool for marketing and promotion. Because the entries are short, and often full of links, they are more keyword heavy than standard articles often are. Plus, being short, they are easy for your customers to read (and you to write), so they are more likely to come back daily to see what you might have to say on that day.
Blogs are extremely easy to update regularly. If you can type on a word processor you can create a blog post.
Once your blog site is in place, making changes and updates doesn't require any technical skill. Simply add a post, edit a post, or re-arrange your layout.
