I am finally going to start posting weekly blogs to our customers. I have realized for a long time that blogging is one of the best things that you can do for SEO. I have a wife who is a professional writer and can easily put a couple of blogs out per week. Don't know why I waited so long. I contacted my web designer and they can incorporate a blog onto our site for a pretty substantial price. Or, I can use WordPress or Blogger for free and just link to it. For SEO purposes, I would assume that having the blog on our site would be the way to go.... wouldn't it? Im just looking for some pros and cons for doing both.
