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. This way you'll be able to know which products your audience are responding to and which ones aren't generating any profits for your business. This is especially important if you are investing into paid advertising to drive traffic and promote products as an affiliate... 

An e-commerce merchant that wants to be able to reach a wider base of internet users and shoppers may hire an affiliate. An affiliate could be the owner of multiple websites or email marketing lists; therefore, the more websites or email lists that an affiliate has, the wider his network. The affiliate that has been hired would then communicate and promote the products offered on the ecommerce platform to his network. The affiliate does this by implementing banner ads, text ads and/or links on their multiple owned websites or via email to their clientele. Advertisement could be in the form of articles, videos, images, etc., which are used to draw an audience’s attention to a service or product.
Please note that some of the links below are affiliate links and at no additional cost to you, I will earn a commission. Know that I only recommend products, tools and learning resources I've personally used and believe are genuinely helpful, not because of the small commissions I make if you decide to purchase them. Most of all, I would never advocate for buying something that you can't afford or that you're not yet ready to implement.
In November 1994, CDNow launched its BuyWeb program. CDNow had the idea that music-oriented websites could review or list albums on their pages that their visitors might be interested in purchasing. These websites could also offer a link that would take visitors directly to CDNow to purchase the albums. The idea for remote purchasing originally arose from conversations with music label Geffen Records in the fall of 1994. The management at Geffen wanted to sell its artists' CD's directly from its website but did not want to implement this capability itself. Geffen asked CDNow if it could design a program where CDNow would handle the order fulfillment. Geffen realized that CDNow could link directly from the artist on its website to Geffen's website, bypassing the CDNow home page and going directly to an artist's music page.[10]
Individual sellers and companies offering products or services have to deal with their consumers and ensure they are satisfied with what they have purchased. Thanks to the affiliate marketing structure, you’ll never have to be concerned with customer support or customer satisfaction. The entire job of the affiliate marketer is to link the seller with the consumer. The seller deals with any consumer complaints after you receive your commission from the sale.
Whether it’s an important consumer application, a specialist app to solve a particular niche problem, or even a time-wasting game you can play on your phone, you can create a massively successful business if you build software that helps people. (Look at the rise of Slack—the team communication software that went from side project to billion-dollar company in just 2 years.)

Is it easy? Nope. Is it worth it? It sure is. But that doesn't mean you need to start a blog to make money online today.

You don't need to invest lots of money to make this happen, but you do need to invest lots of time, not only in writing the ebooks, but in marketing them as well.
If my piece of content is so unique and valuable around hiking backpack recommendations, that other reputable outdoor websites are willing to link to it and build the page’s authority, then I’d have a very real opportunity to rank high in organic search for these search terms (meaning, my page will come up first when someone searches for hiking backpacks).
