Affiliate marketing can be a very profitable business or side hustle if done right. Apart from having all the basics of affiliate marketing down, such as having an active blog, SEO optimization, and an engaged audience, it’s essential to hone in on the right niche that will generate your revenue.

But how should you pick the right niche? Which industries are booming? If you keep reading, you’ll find out!

However, before we get started, it’s important to disclose that the industry that you decide to hone in on should resonate with your current brand and your audience. For example, if you’ve been promoting supplements up until now, it might be easy to hop onto the health trend or even into the sports niche. However, it may be difficult to shift your audience’s focus on luxury goods or gaming. Therefore, our recommendation is to hone in on a niche that is relevant to your market and your audience.


Health is something that never goes out of style. Now more than ever before, people are focusing on their health — from nutrition, supplements, and fitness, to alternative medicine. In fact, people are so focused on their health, that the global market for the wellness industry is at a record high of over $4 trillion dollars. For your convenience, we’ve compiled a list of affiliate health niches that are booming in 2021.

People are more focused on their general well being and long term fat loss, rather than quick results with yo-yo effects. Some of the most booming diets of 2021 are paleo, keto, gluten-free, dairy-free, and lactose-free diets, as well as intermittent fasting.

Just to give you an idea of the breadth of the market, according to Grand View Research, the gluten-free market was worth $21.6 billion in 2019 alone, and as of 2021, the dairy alternative market is projected to reach about USD 24.33 billion by 2022.

Alternative health

Alternative medicine is on the rise because people are seeking alternative healing methods that are accessible and affordable alike. People are choosing to follow the advice of the likes of Anthony William, who promotes healing with celery juice, or Wim Hof who swears by cold exposure.

Alternative medicine has multiple booming industries including dietary supplements, CBD creams and capsules, as well as essential oils. As of 2020, the CBD industry is worth over $18 billion, the essential oil market is expected to reach $14.6 billion by 2026, and the supplement market’s worth is estimated at $123.8 billion.

Weight loss and Fitness

The rise of the Instagram fitness models has brought on a new wave of health consciousness that puts fitness at the forefront of many people’s lives. In fact, fitness is so prevalent that it snags more than $3.7 trillion of the global market share per year.

Even though health and fitness are on the rise, global obesity rates have nearly tripled since 1975. As a result, weight loss enthusiasts spend over $60 billion per year on plans, gadgets, and nutrients that help them shed unwanted weight.

The vegan market is booming and continues to grow daily. There are many health benefits of a vegan diet, but many people choose to pursue veganism due to the impact it can have on climate change. Although veganism has been around for decades, it started growing popular in 2010, when restaurants and grocery stores started carrying vegan options.

According to SPINS, a wellness-focused data technology company, the vegan food market value has reached $1.2 billion, and the vegan milk market is worth more than $1.8 billion. In total, the vegan market has $3 billion potential.

Organic products

By 2025, the organic food and beverage market is expected to reach a $350.5 billion potential. This sudden surge in demand for organic products is fueled by the growing number of health issues, allergies, and complications associated with GMO foods, foods containing MSG, growth hormones, antibiotics, preservatives, and artificial flavors and colorings.


People love to treat themselves, especially when it comes to their hobbies. Most consumers justify spending money on their hobbies by viewing them as an investment that can pay off in the future. Whether it’s becoming a professional gamer or makeup artist, indulging in your hobbies and nurturing your talents can become lucrative.

The gaming industry is gaining popularity and momentum each year. According to CyberAthletiks, there are over 2.5 billion gamers in the world that play games on computers, phones, and gaming consoles. Access to platforms like Twitch has made gaming more accessible than ever, allowing gamers to watch other gamers stream their gameplay. According to Business Insider, the gaming industry is worth well over $120 billion.


Traveling has always been popular, although it has come to a halt due to the global coronavirus pandemic. However, before the enforced travel restrictions, Statista stated that the global travel and hospitality market was worth more than $7 trillion.


The cosmetic industry has greatly benefited from the rise of Instagram and YouTube. Trendy, aesthetically pleasing photos and makeup tutorials are all over the platforms, creating endless cycles of product placement and exposure. Accordingly, the make up industry is expected to reach an $805 billion value by the year 2023.

Luxury goods

Even though most of the world falls into the lower-middle-class, there are tons of wealthy people out there who have a huge purchasing power. These people like to stand out from the crowd and show off their wealth, and therefore the luxury goods market is on the rise.

According to Forbes, the luxury watch market is growing at a steady pace and was the second best performing market in 2020. As for jewelry, the market is significantly smaller, but it is growing twice as fast as the luxury watch market.


The luxury skincare, make-up, and beauty tools market is rising by approximately 3.9% every year and is expected to reach an $86.1 million value by the year 2026.


Sports is a great affiliate niche because it caters to sports enthusiasts, athletes, and spectators alike. According to Statista, the sporting goods market is valued at over $65 billion and is only expected to grow.

Golf is seemingly one of the most overlooked affiliate niches, with a surprisingly high estimated market value of over $23.3 billion in the US alone. The revenue comes from country club memberships and equipment and attire purchases.


E-sports are slowly making their debut into official league sports such as the NHL, NFL, or NBA. According to Business Insider, the e-sports market was worth over $454 million in 2019 and is expected to skyrocket to a $1.5 billion value by the year 2023.

E-sports were popularized by streaming platforms such as Twitch and were quickly picked up by established corporations such as Blizzard or Activision, which create worldwide prized e-sports tournaments each year.


Yoga has been around for centuries but has only gained a massive following in the last decade. Yoga affiliate programs focus on selling yoga app subscriptions with tailored programs, as well as equipment such as blocks, mats, or yoga socks. The Yoga market is expected to snag a $215. billion market share by 2025.

Stay consistent and hungry

Now that we’ve given you a lowdown of all the booming affiliate niches of 2020, it’s time to choose the ones you think are the most promising. Remember that your revenue is based on the sales price percentage of the products that you’re selling and that your success depends on how well you optimize your content on the web. Choose the right keywords and the right niche that speaks to your audience and reflects your brand, and you’re good to go.

While some say affiliate marketing is dead, we can see it is still thriving. 2018 is seeing an incredible shift from old to new marketing methods.
