I would like to work from home and am looking into blogging. I literally have no idea what I’d write about (I’m interested in several different things that are not related to one another) and am assuming I’d need sponsorship to actually make money. Since I know what assuming gets me, I am doing my homework before I do anything else. Thanks for all the info and any other advice is appreciated.

As always, a fantastic post Jon. Have just shared on G+ with the comment that you are simply the best at what you do. I love your style, and the practical advice is invaluable. I was particularly interested in your downplay of using twitter, FB etc to hope to grow your blog, but what you said makes total sense. As someone who is building an author’s platform prior to publication, I’d been hesitant to sell products, but no more. Thanks so much for your inspiration.

There is a lot of room for new bloggers, and there is plenty of room for growth well into the future. I believe that companies and advertisers are only recently starting to realize the value of online influencers, such as bloggers, which means that the blogging world will continue to grow well into the future and that opportunities for making money from a blog will continue to increase.
The next thing you do is start sending traffic to your landing page. For example, you could go out and do guest posts and link back to this big article. You could run Facebook Ads that are targeted towards the right audience. You could link to other bloggers in the post and then email them and ask for a simple tweet. Here are some more traffic tips.
Make it easy. My blog name isn't the easiest for a person to spell, and even I sometimes jumble it when I'm spelling it to someone. So, my top tip would be to make sure that it is easy to type. I've seen blog names that are extremely long, contain words that are difficult to spell, and so on. Instead, you should make it as easy as possible for your readers.
Once you setup your account on AdSense you will be given a code to add to your blog. This code will automatically display advertisements on your blog from companies who are part of Google’s advertising network. You may see ads from small companies related to your topic, or you may see ads from large companies that are completely unrelated to your topic.
