My first tip is simple: launch your blog. Post a couple of times. Then stop. Silence. You have a snazzy design for your blog. You link to it from every page on your site. That should be enough, right?
Wrong. The first thing most readers do when they visit a business blog is look for the date of the last post. If it’s more than a month in the past, we click quietly away.
If you don’t keep posting new content, you’re creating another stone for the business blog graveyard. In other words, it’s better not to blog at all than to create a blog and never update it.
TIP: Think of blogging as tweeting on steroids. You get more than 140 characters, but you don’t have to change the world with every post. It’s better to write short and to post more frequently. Even 100 words to 200 words (like this).
Try for once a week; at the very least post three times a month. Want to learn from the master of short blog posts? Study Seth Godin at http://sethgodin.typepad.com.
