A blog is not a blog without content so once you’ve set your blog up you need to focus your attention upon creating useful content. What you choose to create will depend a little on the topic that you choose to write about (on that note, most successful bloggers have some focus to their blogging whether that be a niche or a demographic that they write for).

If your niche doesn’t allow you to promote or build premium products (anything over around $100 per unit) then think about getting a solid mix of offerings and building it up over time. I remember Darren Rowse saying that initially Amazon Associates was a really small source of income but over the years it has really started to add up. Think eBooks, affiliates, consulting, books, etc. and you’re starting to build an income stream.

Making money through blogging requires a carefully thought out topic. If you have an existing blog with a small audience, be honest when considering whether the topic has broad appeal that isn't already covered by other established bloggers. If it does, great! Otherwise, there's nothing wrong with starting a second blog that will be more successful in attracting an audience, marketing itself, and making money through a variety of methods described below.
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??
Thanks Donna for taking the time to write this excellent comment. I agree with you 100%. A blog can give you an income from offline sources and is a great way of diversifying into different areas, but again it also depends on the niche you find yourself in. I always say to people to not be too reliant on one source of traffic or one source of income, because they can vanish pretty quickly.

Thanks for sharing all this useful and relevant information Jon. The most interesting and surprising lesson was the one where you mentioned that spending a lot of time on social media outlets doesn’t really help. I also specifically liked how you set the tone about the fact that you’re not just a blogger and that you’re an expert…etc. This is some confidence needed to be successful in anything.
If you’re passionate about something, it will show in your content. Readers will be able to see your genuineness and will be attracted to that. This is probably the most important thing you will learn about blogging. You can try everything in the world and use every tool known to man to be successful, but if you’re not genuine, people will see right through it.
