Don’t put all your eggs in one basket. If you only promote one merchant’s products, you are stuck with their commissions, their landing pages, and ultimately, their conversion rates. It is important to work with many different merchants in your niche and promote a wide range of products. This affiliate marketing strategy will diversify the amount of commissions you make and create a steadier revenue stream for your website.
Your niche doesn't necessarily need to be an area you're already an expert in. You can also choose a specialized area which you're enthusiastic or interested in learning more about.Think of Oprah, she doesn't market herself as an expert, but she frequently brings other experts on her show. You can do the same in your niche, by giving other experts a platform to promote themselves in exchange for content creation.
Know when (and when not) to use Viglinks and Skimlinks. If you applied to an affiliate program but were denied, you might be able to still be an affiliate for that advertiser through a secondary affiliate program like VigLink or Skimlinks. Basically, they themselves are affiliates and will split their affiliate commission with you if you put their affiliate link in your content for an advertiser. Obviously, the commission rate is lower for you in this case, so if you ever are accepted into the advertiser’s affiliate program directly, immediately switch from using VigLink / Skimlinks affiliate links to your own.
When promoting affiliate offers, just make sure you are fully aware of all the terms and conditions attached to your affiliate program. Some programs can be strict about how they allow you to promote their products. For example, some may limit you to banner ads and links only, while others will allow you to use paid advertising, but won't allow email marketing.
What kind of commission do they offer? One-time commissions or recurring commissions? For example, many programs pay you one time for sending a customer. On the other hand, some programs like membership sites or SaaS (software as a service) programs will pay you a commission as long as the person you referred is a paying customer. Recurring commissions are great when you can find them!
If the answer to each of these questions is a resounding yes, rather than jumping to conclusions immediately, take time to research whether or not others are out there making a sustainable affiliate income from products and content in this niche. In a sense, competition is a good thing here—it'll help you validate your idea and prove that it's worth of building a business around.
