At the time, I had a ton of people reaching out wanting to hire me (I ranked my self #1 in Google for WordPress SEO Consultant, WordPress SEO Expert, many other good keywords). Unfortunately I struggled with basic things you need to run a service-based business… keeping track of clients, time management, and making sure I was charging clients for my time (and getting them to create content which often seemed impossible).

This was a wealth of helpful information, thanks. In the first section you described how you found your niche. Any more suggestions on how I would find a niche that would be profitable? I understand you probably want to find something that you can write good content on, but what steps would you take to make sure to validate that it will be a good niche to work on? Thanks for any help Tom.

Whatever your audience needs, you may be able to find an affiliate link for it. The beauty is that you are able to provide links to products that could really help to improve your readers’ lives, and you are able to earn a profit in the process.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources.
