I literally went from $20k/year to $150k/year in 2 years – see my 2018 income reports. I did this by dropping my web design/SEO clients and tried to make money with affiliate marketing (I write SEO/speed optimization tutorials). 90% of my affiliate income comes from SiteGround, a hosting company who awarded me affiliate of the month in July, 2017 when I made $9k in 1 month. Since then I have continued to hit numbers like this – the screenshot below is from March, 2018 when I made $14.5k in 1 month (just with SiteGround). I have other affiliates too.
While your site is still new, it's a good idea to start capitalizing on someone else's audience. Continue focusing on building your own content, but also considering writing content for a few big, high-traffic blogs that are relevant for your niche. By writing content for a bigger site, you are able to get in front of another audience and showcase your expertise on a particular topic. This will eventually lead to more traffic to your site, as well.
Since you’re essentially a freelancer, you get ultimate independence in setting your own goals, redirecting your path when you feel so inclined, choosing the products that interest you, and even determining your own hours. This convenience means you can diversify your portfolio if you like or focus solely on simple and straightforward campaigns. You’ll also be free from company restrictions and regulations as well as ill-performing teams.
