Thanks to the crummy economy, there has been a bit of a gold rush online lately. Whether or not this is a good thing remains to be seen. Generally, it is not a good thing because a lot of people who have no business in the business of Internet publishing are making a run at it. To to tell you the absolute truth, unless you are a celebrity or a fabulous writer, nobody cares about your little blog, and they never will. It's a cruel world because celebrities don't need the money, and fabulous writers often waste their talent with blogs.
If you think of yourself as a blogger, you are dead in the water. Frankly, to be called a "blogger" is a bit of an insult, and if you call yourself that, it is even worse. If you want to succeed at this, you must take the attitude that you are no mere blogger. You are, in fact, a publisher who happens to publish on the Internet. You are a writer who writes for themselves and their audience instead of for some bossy editor.
You are either a writer or a savvy business person who can hire other people to write for you, using the Internet to wangle some dollars out of their talent.
Those are your choices: Wrtier or business person. Bloggers are people who keep diaries online. Nothing wrong with it, but it is not a business. Beyond your friends and family, chances are slim that anyone will read your blog. Sorry to break it to you, but that's the way it is.
Step one in making money on the Internet: Stop thinking of yourself as a blogger or "Internet marketer." You are an online publisher (or broadcaster if you prefer). You are a writer (or maker of videos and audio files). If you take that attitude, you will succeed. You may fail many times before you find what works, but you will succeed eventually.
Just remember that you will fail. Every blogger fails. There's nothing wrong with it. Thomas Edison literally failed 10,000 times before he succeeded, and thank goodness he did!
