Best Affiliate Marketing Niches in 2021



Once it began to surge in the early 2010s, affiliate marketing quickly became one of the hottest internet industries. Today, it is a preferred field of employment for those looking to avoid nine to five working hours and remains one of the most popular strategies for passive income generation.

More than 80% of brands now have affiliate programs, and advertisers generate up to 30% of all sales via these schemes. All in all, this sector is responsible for 16% of all global e-commerce revenues. If you are looking to get in on this action, these are the best niches to sink your teeth into en route to profits.

Online Gambling

The online gambling sector came into existence in 1994, when Antigua and Barbuda passed the Free Trade and Processing Act. From its inception, this industry has been on an upward trajectory. However, it got a rocket boost with the invention of the smartphone. Now, projections say that the global market will hit $127 billion by 2027, almost doubling in size in six years.

As operators aim to incorporate more skill-based games and blockchain technology into their platforms, so should interest from millennials and generation Z members grow. These online casinos monetize the most of your referral traffic compare to other online services because they tie you in with your referral for life. The advent of social casino apps also does its part to attract a younger baby boomer crowd, which has more disposable income to spend on entertainment. Thus, this seems like an ideal time to catch this niche in a period of massive expansion. Online poker platforms recently made a comeback, and those sites offer generous referral commissions as well.

Fitness and Wellness

The fitness industry is enormous, worth close to $90 billion. Nevertheless, its digital counterpart is also not doing too shabby either. Another sector tied to terrific wellness is the global supplement market, which should reach a stunning size of $272 billion by 2028. Therefore, it is clear people’s interest in their well-being is higher than ever.

That said, how good are the affiliate commissions in these two industries. The answer is excellent. Established brands in the vitamin/supplement field have affiliate systems that offer commissions between 15% to 25%. Yet, newcomers looking to break into this sphere may provide ridiculous fees that are more than 50% of the value of their products. Fitness schemes are less generous. Some provide 5% to 10% commissions on gadgets such as heart-monitoring watches, while others offer a fixed rate if you get friends to sign up for a fitness app.

The main contributing factors to the rise of beauty product sales are the economic growth of emerging nations and rising disposable income.

The term – beauty products encompasses cosmetics, fragrances, and personal care items. YouTubers, Instagram influencers, and reviews sites make around 5% to 15% per generated sale, depending on the brand. Some skincare brands like Alchimie Forever pump their commissions up to 20%, while beauty education platforms offer fees that fall in the range of 20% to 50% per video course sale.

Self-Improvement and Mental Health

Consultancy firm Grand View Research claims that the global personal development market had a value of $38 billion in 2019 and that it will continue growing at an annual rate of 5.1% until 2027. An increased desire for happiness and self-recognition drives individuals to look to attain what many now call emotional fitness. Employers are also investing in these kinds of programs for their employees, further fueling this market’s growth.

Most online personal development programs pay similar commissions to other educational platforms. Meaning, standard referral fees range from 15% to 30%. Nevertheless, some sites that provide commissions that go up to 50% and higher. The Self Development Network lets marketers earn 60% commissions, and MindValley offers a 50% referral fee for all products sold via an affiliate link.
