If you decide to go into affiliate marketing, understand that you will need a lot of very targeted traffic if you want to make any real money. Those affiliate offers also need to provide a high commission amount to you on each sale. You also need to ensure that the returns or chargebacks for those products or services are low. The last thing you want to do is to sell a product or service that provides very little value and gets returned often.
After that, you need to make a choice about how to construct an online presence that helps you achieve that goal. Maybe you need to set up an e-commerce site. If you’re interested in publishing content to drive awareness and subscribers, look into setting up a blog. A simple website or landing page with a lead capture form can help you start developing your brand and generating traffic. A basic analytics platform (like Google Analytics, which is free) can help you start to measure how you are tracking towards your initial goal.
