What are the Best Affiliate Marketing Niches for 2021?

Affiliate marketing is often misunderstood. Even many experienced marketers make the mistake of thinking that affiliate marketing equals to passive income. But that couldn’t be further from the truth – affiliate marketing takes serious work for optimal results. Thankfully, there are niche industries out there that almost always yield profit and represent the best affiliate marketing niches.

Let’s look into them. But first, let’s remind ourselves of the definition of affiliate marketing.

What is Affiliate Marketing?

In a nutshell, affiliate marketing means sharing information about a product or service and getting paid for that.

Here is how that works. First, you pick a partner program you want and promote items and services to other people. Then, you get a commission for each sale you helped realize.

Sounds easy, right? But there are many nuances to it. And the best way to grasp them is to start from niches where it’s easier to succeed.

Wellness and Lifestyle

Research shows that the global health and market industry will climb to a value of 6 trillion by 2025. The pandemic only helped push those numbers up. People are willing to spend their hard-earned money to live more quality lives.

Common topics found in this niche are diet and nutrition, skincare, products for exercising, personal training programs, and more.

While each demographic group has a different approach to this sector, we all had a mind-shift when Covid-19 disrupted our daily lives. We started feverishly searching nutritional recipes and exercise programs. So do your research to find out these nuances that set apart different demographic categories to make sure you are striking the right tone with your affiliate products and services.

Gender, location, age – all of these factors play a role in specifics of health and wellness concerns.

And of course, if you want to stay in the know, you need to be updated on the novelties and gather all the fresh information coming out of the industry. A lot of that will further shape public opinion, which leads to you having to hone your marketing strategies to these changes.


Money makes the world go round.

Almost every adult on the planet uses some sort of financial service – credit cards, bank accounts, they take out loans, or they trade on Forex.

Well, the financial industry comprises financial technology businesses as well. These so-called fintech enterprises attract a lot of people since they are basically a part of technology and the internet that develops cost-optimizing solutions.

There are staggering numbers at play – the financial service market will probably grow to $22.5 trillion worldwide. Just one of the reasons for this huge growth are the cryptocurrency and blockchain industries.

Financial companies frequently enlist affiliate marketing to promote their services and products, and a plus side for you is that they typically have one of the highest commissions in the industry – about $100 per sale!

Pet Care

Surprised? Don’t be. Yearly spending on pets is getting near $100 billion in the United States.

And with the pandemic changing our spending habits, people readily spend hours online scouring the internet for their furry (or sleek – we see you, amphibia and reptile aficionados!) companions’ favorite snacks and toys.

This affiliate marketing niche often deals with grooming items, pet clothing, specialty pet food, therapy dogs, and more.

Common Thread Collective gathered useful information for marketers dealing with this niche. Here is why pet owners like online shopping for their pets:

  • Convenience: Your website visitors will appreciate an easy purchasing experience.
  • Information and choices: Visitors appreciate a lot of product information. And get creative – utilize the help of infographic, pie charts, videos, stats, and more.
  • Comparison tools: Present item data in a way that people can tell them apart and compare them to other items.
  • Relationships: Share pet videos, funny stories, heartwarming adoption tales, and more. All of these things help build a loyal community and following on social media.


We hate to say it, but gambling is right up there at the top of the best affiliate marketing niches. While we’re not the ones to promote gambling and addictive behavior, but the numbers speak for themselves: the worldwide marketplace for gambling is anticipated to climb to $516.03 billion this year.

Gambling really entered its new golden era thanks to the internet. The online space is chock-full of online casinos and betting sites, and a lot of people flock there to satisfy their thrill-seeking urges.

Sports betting is one of those niches within the niche where you may find even more success. There are events that people follow religiously, and one good example is the international football tournament (UEFA), the NFL Superbowl, and the Olympic Games.

When those events come round the corner, interest in sport betting climbers up even more. As an affiliate marketer, it becomes easier than ever to succeed during those times!


No matter if you are a newbie or an experienced affiliate marketer, you should always have a wide scope of knowledge of affiliate marketing. One important pillar of knowledge is knowing how and where the most money is made.
