One of the most beautiful and exciting qualities about blogging is that you can create a blog that deals with any subject area that you are either knowledgeable or passionate about (and preferably both!). You can write about personal finance, careers, real estate, getting into business, technology, cooking, travel, personal health, or just about any topic you choose.
What a huge, great list of ideas – bookmarked this as I know I’ll be coming back to go over it again and again. Here’s another item that could have made the list. I found a financial directory that’s useful for info on making money online. It’s http://money.madbeetech.com. What I like about it is that each directory listing includes ebooks and videos that can be instantly downloaded. All sorts of stuff for people who have their own website, and people who don’t (but still want to make money online).

eBay: With eBay, the procedure is very similar. You simply start by becoming an eBay seller and stay in good standing by making sure your PayPal account is verified, and then you can sign up for your store. These three steps allow you to piggyback on eBay’s reputation, reach, and sales and marketing infrastructure in order to sell your own products.
Great article, I have tried a few over the years. I had a side business cleaning offices for years. It did great, but I hated never being able to take more than 3-4 days vacation, so I eventually gave up. I tried MTurk, but if you multiplied my earnings on an hourly basis, it was a little over $6/hr. My blog is much worse, probably less than $0.25/hr.
High-ticket consulting or coaching: You could sell your own high-ticket consulting or coaching products from your website. You'll still need a website, merchant account, sales funnel, lead magnet and many other items. But you can easily earn a substantial amount of money from each individual customer, making it well worth the arduous setup required. 
Even if you have a work at home job that more or less pays the bills, there's a lot to be said for extra cash opportunities. There are many different little “side-gigs” I've had access to over the years that have seriously come in handy for me. I've used them to help pay for Christmas, gas money, extra money for movie and a dinner out, and even just to help make ends meet week to week.
Research individual companies in your desired niche: If possible, it’s always better to become an affiliate directly with a company (if they have an internal affiliate program), as no one else will be dipping into your commission rate. This is the preferred route for most of the prominent affiliate marketers, including Pat Flynn. Unfortunately, it’s also the most work, as you’ll have to do the research yourself to see who offers programs (they’re usually listed in the website footer).
Getting businesses to advertise on your podcast, either at the beginning or end or both is a great way to create a revenue through podcasts. Most businesses won’t be keen to advertise on your podcast until you can prove a large number of listeners. Therefore, it is unlikely you will be able to start out from the get-go with sponsors. But once you accumulate regular listeners or a high number of downloads from iTunes, you can start to sell advertising space on your podcasts.
Sponsored posts work much in the same way as paid guest posts, but they are posted by big businesses instead of individual bloggers. Therefore, the scope for fees is much higher, as businesses have larger marketing budgets than humble bloggers. Having sponsored posts by large companies will also help promote your site as reputable and as a leader in its field.
There are different ways to market an ebook. One of the most common is through Amazon’s Kindle program. They can help you with all the steps to both publish and market your ebook through their incredibly popular platform. There are some specialized sets of writing software that will help with not only writing your ebook, but also formatting it correctly for the Amazon market as well Barnes & Noble and iTunes
