You may disagree - you may think to yourself: “I have things to say and people will want to read them”. If that’s you, sorry, move along sir or madam, I wasn’t talking to you, I was talking to the other reader who doesn’t have things to say, but a consultant / friend / neighbor told them they should start a blog and post things because it will help their business.
If you are considering blogging because you’ve either been told or believe that it will help your search rankings, it will help personalize your business or drive traffic to your site. I’m telling you that you don’t need a blog.
