One thing you should strongly consider is promoting digital information products. These products are attractive for two reasons. First, they have higher conversion rates because the customers can get instant access and instant gratification when they purchase. Second, they typically offer much higher commission rates than physical products -- which means more profits for you.
Outsourcing is so crucially important because that is how you will take your affiliate marketing business from just a small business that makes you a few extra bucks per month to a 5 or 6 figure monster that earns you a passive income. While one site is being outsourced and making you money, you can build a second one. While those two are outsourced and making you money, you can build a third one, and so on. So many new affiliate marketers take their first commission checks and just spend in on themselves. If they re-invested that into outsourcing instead, the returns would be much bigger. My business didn’t truly start taking off until I learned about the power of outsourcing.
Now, truth be told, affiliate marketing does come with some costs. Fortunately, those costs are rather small when compared to starting other businesses. For example, if you want to succeed with affiliate marketing in the same way that I teach it, you’ll need a website. In order to have a website, you need to pay for “website hosting”. If you don’t know what website hosting is, don’t worry, we’ll get to that, but website hosting does cost a few bucks per month (generally under $10 / mo). If you have about $40 for startup costs and about $10 / mo for recurring expenses, this is entirely doable. There are many other optional expenses for affiliate marketing, which I will also get into, but those optional expenses are used more for speeding up the path to success (outsourcing, etc.) rather than a requirement for success. When I first started my affiliate marketing business, I had about $200 to my name.
I totally agreed with you that affiliated marketing pay the bill more that AdSense does. I was reading a post on bivori that was shared by Reginald on how he made $405 in a month from affiliated marketing yet he made less than $5 from his AdSense account that same month, meaning that he ventured more into affiliated marketing the more rather than AdSense, but the fact is traffic is the real back-born of a successful affiliated internet marketers and choosing the right niche.
