Solid numbers about blogging incomes are hard to come by. For example, in the US, the Bureau of Labor Statistics lump bloggers in the very broad category of “Writers and Authors” which has a median income of $61,240 per year. That’s not an accurate measure since there are vastly different occupations included in that category. Information from small surveys and anecdotal evidence can also be found online, but much of it is outdated or taken from tiny sample sizes.
One added benefit is that if someone clicks on a link from your website to Amazon and ends up buying multiple items (not just the item you are promoting), then you would get credit for the entire sale! Imagine you recommend a book on Amazon, your visitor goes to Amazon to buy a book - and while they're there they end up buying a new TV, a Sony PlayStation, and some other things... you get credit for all of the sales. Not only that but you also earn from any sales you make in the following 15 days from that customer.
The answer is yes. However, I would caution against it. The reason is, when you use a free service, you don’t have as much control over your blog—the free service does. This can be risky, especially if you will rely on your blog for income. A self-hosted WordPress blog is my recommendation and can be started very inexpensively. See my step-by-step tutorial here.
I have a lot of great ideas, but most of them are just thoughts and theories, and it seems that no one would want to read about, even pay for, ideas in which I am not a complete expert on. My greatest talent, perhaps, is being a prolific writer. Otherwise, I’m more of a Cliff Craven I know a lot about some things, and some about a lot of things. How does THIS make MONEY??
Creating a job board on your site is a great way to make your blog "sticky" - meaning you get visitors returning again and again. It's also a great way to earn some extra cash while also providing a valuable service. Darren Rowse from ProBlogger runs a hugely popular job board where he charges $70 for a 30-day listing. With around 70 listings per month, he's bringing in some solid earnings with relatively little investment of time or money.
Fortunately, there are many resources available to help. In addition to the BlogHer events and site, some of my personal favorites for learning tips on writing compelling content, marketing and monetizing are Fizzle.com, MichaelHyatt.com and Problogger.net. All three provide lots of free advice (and more in-depth training and support is available for a fee).
