The second reason that niche topics will bring you more money is because competition is less fierce. Rather than compete against dozens or even hundreds of other marketers, you’ll only have to compete with a handful. In fact, you may not even compete with the other marketers at all. They may become your friends because you share similar interests. Together you will tackle the market to make even more money.
Amazing and thorough breakdown of how it all works! Thank you so much for sharing! a group of 3 friends myself + 2 are about to start affiliate marketing together. Since many advertising rules have changed with affiliate marketing (facebook ads etc.) and many articles have not been updated since, weʻd love any advice or suggestions you have for 2018!

The problem with affiliate marketing, like many other home business options, are the so-called gurus and get-rich-quick programs that suggest affiliate marketing can be done fast and with little effort. Odds are you've read claims of affiliate marketing programs that say you can make hundreds of thousands of dollars a month doing almost nothing ("Three clicks to rich!"). Or, they suggest you can set up your affiliate site, and then forget it, except to check your bank deposits.
I joined Amazon affiliate program a few years ago and put links on my blogs and webpages with NO LUCK until I read a few blog posts about how to use a software program called Market Samurari (link above) to determine which keyword phrases have the most traffic and the least competition. They explained that if you are selling something like dog supplies, the #1 listing in google for the search term “pink dog collars” will only get “20” hits per day, while the search term “dog clothes for big dogs” will get “250” hits per day. (just made up examples, not real numbers). While the general term “dog supplies” has WAY TOO MUCH competition for you to even think about getting to the #1 spot on Google (where all the traffic goes). So the software can tell you exactly what keyword phrases you should target to get the most traffic for the niche you are in.
This is a very common way to promote offers. For example, you will often see a blog post with links to certain products or services. If the reader clicks through and makes a purchase, the blog owner will make a commission. These in-text links blend in with other content on your site and are a great way of promoting an offer within your content, without being over-the-top salesy with banners. 

Always disclose your affiliate relationship. Most visitors will probably understand that graphic ad will lead to your getting paid, but if you write a review or use an in-text link as a recommendation, you want your readers to know that may lead to compensation as well. This ensures you retain transparency and trust with your readers, but also, it's required by the FTC's endorsement rules.
