A blog itself isn't really a business—it's more of a platform for other income streams. Your content alone won't likely make you money. Instead, you'll have to get advertisers, sell services like consulting or speaking, use affiliate marketing to get a percentage of sales from links people click on your blog, or maybe offer products like ebooks or premium content to actually generate income. ProBlogger has an excellent post about these different ways you can make money.
One attractive feature of promoting digital information products is that the commissions tend to be higher than that of physical products; ranging anywhere from 10% to 50% or even higher. As an example, if someone is selling a digital information product for $500 with a 50% commission - you can earn $250 per sale. This is much higher than commissions on physical products due to the high profit margins.
SEO helps improve your website’s visibility in unpaid search engine rankings (also called organic results). If your website is placed higher in search engine results, you are more likely to receive increased traffic to your website. Knowledge of SEO will increase your traffic, thus bringing in readers and the potential to earn money through those readers.
And so, I guess my question here would simply be–would a person who follows your blog about TV shows be interested in paying for a TV-related webinar you created? Would a person who follows your blog about vinyl record collecting want to buy an online course from you? Would a person who follows a travel blog you created want to call you up for coaching lessons?
Consider a free blogging service. Many people opt to create a free blog using popular services such as WordPress.com or Google Blogger. This is a good option for people who aren't familiar with web design, don't want to pay for their own hosting, or enjoy the ease and stability that comes with these services. These services do have limitations on how you can make money using them, however, so make sure your blog won't break the terms of service.
Write content. I like to write an article from beginning to end with no breaks. It may take me an hour to write an article or I may be at it all day. Sometimes, content does span a few days, but for the most part, I like to finish a piece of content in one sitting. I then hand over the content to my editor to fix anything from grammar, punctuation, to the general flow of the article. The only thing she doesn't edit is my monthly income report.
