Have in-depth knowledge in your niche? Package it up into an ebook and sell it on your blog. I'd generally advise against selling it (at least exclusively) on Amazon or Kobo, as you'll probably be able to charge much less. If you've already built up a solid audience, you can probably change anywhere from $5 for a very short one, all the way up to $39+.
Hi. Thank you for your informative post. I’m still looking for the best (least expensive or free) value to use my own domain (not with wordpress.com or the like in the domain name). If you’ve included this information somewhere, I have missed it. I also didn’t see it on the comparison chart? I’m sure it’s probably there, but maybe worded differently…?

Create catchy headlines. You can have the best content in the world, but if your readers don’t recognize it instantly, it’s unlikely they’ll click through. Headlines are especially important because many readers will encounter your content through a feed reader, such as Google Reader, or content site like Digg. They may only see the headline at first, so it needs to communicate what your post will be about in an engaging, entertaining way.[24]

Create a location-independent lifestyle – Blogs are great for working while traveling and producing an income no matter where you might be living. In a recent article that I wrote for Forbes, I talked about how Nomadic Matt, one of the most popular travel bloggers, started his blog so that he could enjoy traveling the world and not be tied to a 9-to-5 desk job.
The one constant with trends is they do not last. They are always based on a new technique or technology and follow an interest cycle. Since human beings by their nature move on to something different, new and perceived as better (and usually ACTUALLY better), if you are attached to any one trend, you are doomed if you don’t adjust and keep up with the times.
Protip: A quick way to tell if others are making money in a particular topic or niche is to do a Google search. Do ads show up at the top of the search results when you type in main keywords for that topic? If so, people are making money in that niche (otherwise they wouldn’t spend money on advertising) and there’s potential for you too. But do note, the absence of ads doesn’t necessarily mean you couldn’t make money in a particular niche. Dig deeper and you might find sites do make money but don’t choose to advertise on Google.
Another great exercise if you’re trying to decide on a niche for your blog is to think about who your ideal reader is. This is the person most likely to visit your blog and get value from your writing. For me, the easiest way to think about this is to use myself as an example. If you’re writing about an interest, then you’re most likely your ideal reader.
I’m so excited for you! I can’t wait to hear about all your success. As you move through these steps, remember to work in bite-sized chunks and keep the blog income formula plastered to the top of your brain. This will help you earn money from blogging as quickly as possible, because you’ll know exactly what you need to do to turn your blog into a blogging for profit machine.
If you're serious about succeeding with your blog, you need to build useful anchor content. It needs to be engaging, keyword centric, insightful, unique and well written. Don't write your content for search engines. Rather, write your content for humans while also paying homage to search engines and what they want. Simply put, it's a skill that develops over time with practice. It's also important to regularly publish your content on a weekly basis.
I am not ashamed to admit that when I was first learning how to build a blog I made a ton of mistakes. You can benefit from more than a decade of my experience so that you don’t repeat these same mistakes when you make your own blog. I created this free guide so that anyone can learn how to blog quickly and easily. And if you get stuck at any point, please send me a message and I will do my best to help you!

This obviously isn't a book on SEO techniques, but I totally disagree with the author that SEO is an "old school" way of generating traffic. The bulk of my traffic has always come from search engines and, while social media is changing how we use the internet, I don't think enough emphasis can be put on the importance of search engines as a source of traffic for most blogs.
