First, its important to dispell the notion that only fanatics spend their time 'blogging'.
For the small business owner (and some corporations, such as Ford Motor Co.) blogging software offers a powerful way to present your products or services to potential customers.
If you change your current website into a 'blog', you will be able to add new text and upload pictures to your website yourself, keeping it fresh and providing search engines with more 'hooks' to grab your potential customers' attention.
What's the difference between a static page website and a blog? A blog will give these benefits:
A blog can be an entire website.
All those fancy graphics on your current website, and any pages you want to keep, can be 'dropped' into your new blog site. This saves you the cost of designing a new site from scratch.
With a dynamic website you will have more control over your business presentation and more effective communication with your customers.
