So Step 2: blog consistently.
Daily is best. If not daily, at least a couple of times a week. At the very least, once a week. Internet followers have short memories. If you disappear from your blog, you disappear from their thoughts. Set up a reminder on your calendar to remind you to blog consistently. Give yourself incentive.
Does it need to be a full-blown article each time? No. In fact, better if not, because people don't have time to read each and every full-blown article.
But don't post stupid. By "stupid" I mean without substance. Even your shortest blog post should say something.
This one says blog consistently.
