Once you have decided that you want to start a business blog, you need to make sure that you choose the right one for your business and audience. If your clients or customers are used to having a vibrant and relaxed interaction with you, a blog that looks very sleek and high class will not draw them. It works the other way around as well.
Below is a short list of business themes available. There are much more on the WordPress site. Some are free and others you need to pay for. It all depends on your needs and your business.
Dara is a theme that has a balance between a professional and a relaxed look. It would suit a blog for students or a discussion group. It is easy to navigate.
Textbook is a theme that is more formal than Dara. It is very well suited to a university blog about serious subjects and discussions. It is not corporate but does give the feeling of order and seriousness.
Aperitive is a theme that is ideal for a restaurant or catering business. It has all the necessary sections and also has the feel of an eatery. It is inviting.
Wayfarer is a theme that bands or other entertainment businesses can use. It has great space for pictures and videos and has the necessary vibrant feel while remaining business-like.
Eris is a very simplistic theme. Any business that is looking for a streamlined or sleek feel, will like this theme. It is no fuss and easy to use.
There are many more of these themes. The theme you choose will determine whether you need to pay a fee or not. Visit WordPress for more information.
