A little personality goes a long way, especially on a business blog. So don’t be afraid to let loose now and again. When done tastefully (and sometimes not so tastefully), it’s bound to make people take notice.
When someone asks you a question, you almost can’t help but think of an answer. Your reader will do the same thing, and you’ll immediately engage them in a conversation. Be careful though. Avoid any questions that can be answered with “no” or “who cares.” In other words, always make your question relevant to your reader’s needs.
A variation on the question technique above, the multiple-choice question is another great way to engage your reader. I don’t know about you, but I love multiple-choice questions. It’s like responding to a poll. As above, make your question relevant to your reader and the article itself.
