As you become comfortable with the affiliate marketing process, you can consider both specialized (e.g. fly fishing) and broad (e.g. weight loss) niches. Don’t forget to track your marketing metrics! They are usually provided by your merchant and/or affiliate network. Tracking your metrics will allow you to see what is working and generating sales and what is not working, causing you to waste time and/or money.
Many advertisers are unaware of the potential of the affiliate marketing business model for their own businesses, in fact, most small businesses have never heard of it. But imagine marketing your products only to interested people for no upfront fee. Paying only when you get results is a risk-free way of advertising that requires no marketing budget to get started. As you can imagine, this is great for any start-up business with little funding for marketing their new brand.
