Many Realtors do not have much expereince writing except for feature sheets and listing descriptions so when I say that you should write blog post often I know that many of you just glaze over and look for another idea. This is a mistake as writing can be both therapeutic for you as well as informative for your readers. Successful Blog writer Liz Strauss has this article, Things Every Reader Wants from a Writer. This may give you a muc better idea of what you should be writing about and give you a good idea of what your blog should contain to humanize you and still set you up to be a professional that people should deal with.
If you have not read Successful Blog before I have to tell you that there are many articles that I have picked up from there that are a great into for you to be a better writer and marketer.
