Write (from Writing Tips for Non Writers, July 8, 2012)

Business blogs are like stores. Why should a customer go into one rather than another?

When she goes in, what prompts her to buy something?

First, be welcoming. Do that by being confident and straightforward.

Explain what you're talking about. Skip the blather.

Then,

1. Get to the point.
2. If there's an action item, say it. 
3. If there's a date and time - an event or deadline - when is it?
4. Is there a cost? 
5. Where can the reader go to act on the blog's recommendations?

You don't need anecdotes or techniques to make a business blog worth people's time.

Writing is a way to put words where people can see them, not a way to make words fancy.

Remember that and you'll be fine.
