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).
If you’re serious about making money selling things online, it’s pretty much impossible to not recommend Shopify. The platform gives you everything you need to get your online store up and running in less than a day including a custom domain, beautiful templates (so you don’t need design skills), secure payment options, and they can even take care of marketing and shipping for you. Whether you’re promoting your own products, designs, or curating other products for people in your niche, Shopify is the best option for powering your online store.
If you're serious about making money online, start a blog. Blogging is one of the easiest and most sustainable income sources. As long as the blog is setup the right way, in the right niche, with the right content targeted at the right audience, and the offer is complementary to the content, you could make a tremendous amount of passive income from a blog.
