I make the bulk of my money from blogging. In addition to the advertising revenue streams mentioned above, I also receive flat rate payments for blogging from various blogs throughout the web. I’m paid to write as a whistleblower, financial analyst, reviewer, commentator, and more. Writing for other sites builds traffic to my personal blog. The traffic for this blog gives me clout to present to advertisers.
Next, you’ll want to pick a WordPress theme from somewhere like ThemeForest, Elegant Themes or OptimizePress. This is the barebones design of your site, which you can then customize with your own branding, copy, and images. That being said, you don’t want to cheap out. It costs less than $100 to buy a theme that will make your website look professional (and you can upgrade to a completely custom design once you get the business going).
