Successful blogging that develops a loyal following comes from sharing your thoughts on a subject in which others will see you as an authority. Nobody wants to listen to somebody ramble on about something they know nothing about, and many of the followers attracted to a specific blog will most likely spot a fraud portraying himself as an expert if it is in their area of interest. So blog what you know, not what you want to know. You will then begin to attract a large group of followers who listen to you because they can recognize that you know what you're chatting about. It is then that you will be in the position to reap the benefits of a perpetual flow of advertising revenue from those marketers who recognize the worth of displaying themselves in your blog.
