I really think Affiliate marketing is wonderful provided people don’t recommend products just for the sake of selling them.
When compared to the costs of advertising or other marketing initiatives, affiliate marketing is far more cost-effective. Because it is performance-based, affiliates are only paid when they generate a sale. Businesses set up the commission structure in advance and avoid wasting money on ineffective advertising campaigns.

As much as you want to narrow down what you are writing about, you also need to make sure the niche you pick will give you enough topics to write about. If you pick pink collars for dogs, it’s going to be hard to write 50 or 100 articles on that, but if you decide to go for dog accessories, you might have more luck!
FTC best practices list specific things that every affiliate website should have. This generally features two main parts. The first is an affiliate disclosure going into detail about how your relationship with these affiliate partners works. This includes making profit off any and all purchases made. The second piece of staying in the FTC’s good graces means also having a privacy policy that discusses how cookies work, what information is collected from visitors, as well how that information is used.
