The biggest asset your blog can have is good, unique content.
This is content that can't be found anywhere else.
For your business, this should be quite simple and easy.
No one else would know more about current issues or news affecting your business before you do.
Once you have good and unique content, the writing style must match your audience.
This allows the blog to establish a type of dialogue with the readers.
The style, personality, diction and knowledge must match your intended audience.
You would not write in the same style when you write for middle schoolers as you would for professional business men.
Depending on who your target audience is, it is crucial you write in a style that is most comfortable to them.
A major pit that many bloggers fall into is their lack of new posts and material.
Visitors don't want to come to a site only to see the newest post be from a month or two ago.
This will cause you to lose repeat visitors fairly quickly.
Top bloggers post multiple times a day.
This is attractive to its visitors as they know they will always see new content when visiting the page.
One of the best things you can do for your blog, is to promote visitor interaction through comments.
The next best thing you can do is to respond to them.
Inviting your readers to comment, and then totally ignoring their comments would give them the perception that they have a voice, but their voice is not heard.
Your business is your customers.
No matter what industry or field you're in, the biggest people you have to please is your customers.
Unhappy customers will not be repeat customers.
