Affiliate marketing is now a $21.60 billion global industry, and it is growing at 8% every year. By 2031, it is projected to reach $31.7 billion.

These numbers are not surprising when you look at what the channel actually delivers. Brands earn an average of $15 for every $1 spent on affiliate marketing. It drives 16% of all ecommerce sales in the United States. And 81% of brands worldwide now run some form of affiliate program.

This post covers the latest affiliate marketing statistics for 2026, across market size, top niches, earnings, traffic sources, networks, and the risks that come with the channel.

Let’s get into the details without much ado.

Affiliate Marketing Market size & growth

As of 2026, the affiliate marketing industry is valued at $21.60 billion globally.

The global affiliate marketing industry was valued at $18.5 billion in 2024. According to Cognitive Market Research, this figure is projected to reach $31.7 billion by 2031, growing at a compound annual growth rate (CAGR) of 8% from 2024 to 2031.

The table below shows the projected global affiliate marketing market size from 2024 through 2031:

Year	Estimated Global Market Size	Growth vs. Previous Year
2024	$18.51 billion	Baseline
2025	$20.00 billion	+8.0%
2026	$21.60 billion	+8.0%
2027*	$23.32 billion	+8.0%
2028*	$25.19 billion	+8.0%
2029*	$27.20 billion	+8.0%
2030*	$29.38 billion	+8.0%
2031*	$31.73 billion	+8.0%

The platform (software) side of affiliate marketing was valued at $22.58 billion in 2025 and is expected to reach further to $35.7 billion by 2033.

(Note: This figure refers specifically to affiliate marketing software and platforms, not the broader industry spend figure. 

To put the growth in perspective, the industry has roughly doubled in size over the last decade, driven by the rise of content-based publishing, ecommerce expansion, and performance-based advertising models that give brands a measurable return on their spend.

From a return standpoint, on average, affiliate programs deliver brands a 1,400% ROI, generating $15 in revenue for every $1 spent on affiliate advertising. 

This performance-based efficiency is one of the main reasons adoption keeps growing. Affiliate marketing currently drives 16% of all ecommerce sales in Canada and the United States, making it one of the four largest sources of online orders.

For major brands, affiliate programs contribute anywhere from 5% to 25% of their total online sales.

Affiliate Marketing Adoption by Brands & Publishers

81% of brands worldwide use affiliate marketing programs, which commissioned Forrester Consulting to survey advertisers and publishers on how they use affiliate programs. 

On the publisher side, 84% of publishers participate in at least one affiliate program. Infact, these brands use affiliate programs at multiple points in the customer journey, not just at the point of sale.

83% of advertisers targeted consumers during the discovery and awareness phase, 79% used affiliate programs at the conversion or purchase stage, and 79% used them to create ongoing customer engagement after the initial sale.

When surveyed about the performance of their affiliate programs, 33% of marketers described their programs as highly successful, and 42% described them as successful. Only 3% said their programs were not successful, and 2% said they were not successful at all. 

The table below breaks this down:

Program Success Rating	Share of Marketers
Highly Successful	33%
Successful	42%
Somewhat Successful	20%
Not Successful	3%
Not at All Successful	2%

The business case for running an affiliate program is supported by the revenue impact reported by brands. 

• 65% of retailers say their affiliate programs have increased their annual revenue by up to 20% (Awin). 
• 31% of web publishers say affiliate marketing is their top revenue source (eMarketer), and 76% of publishers say affiliate marketing makes monetizing their website simple (Sovrn). 

These numbers point to an arrangement that works reasonably well for both sides of the relationship.

Beyond this, 79% of marketers use affiliate marketing to engage new customers, while 46% use it for customer retention.

Top Niches & Commission Rates

When it comes to how much affiliate marketing contributes to overall sales, affiliate programs account for 5% to 25% of total online sales for major brands, with the range depending on the brand’s vertical, commission structure, and how actively the affiliate program is managed. 

At a broader level, affiliate marketing is responsible for 16% of all ecommerce orders in the United States and Canada, making it one of the four largest online sales channels by volume.

Globally, Retail and ecommerce account for the largest share by far, generating 44% of all global affiliate marketing revenue. Telecom and media come in second at 25%, followed by travel and leisure at 16%, with all other industries making up the remaining 15%.

The table below shows this global revenue distribution:

Retail & Ecommerce	44%

All Others	15%

Most Profitable Niches by Monthly Earnings

When looking at which niches actually pay affiliates the most per month, the rankings shift significantly. 

SaaS products pay the highest commission rates of any niche. According to the Influencer Marketing Hub Affiliate Marketing Benchmark Report, SaaS affiliate programs pay commissions ranging from 20% to 70%, depending on the product and its pricing tier.

Many SaaS programs also offer recurring commissions. This recurring structure is a major reason why 90% of affiliates say they are more likely to promote products with recurring commissions or longer cookie durations. 

The average monthly revenue for software affiliates sits at $5,967. 

Finance and fintech programs work differently from most other niches. Rather than paying a percentage of a sale, many finance programs pay a flat fee of $50 to $200 per qualified lead. 

Finance is consistently rated among the most profitable niches for affiliates, with commission rates typically ranging from 35% to 40% for programs that do offer percentage-based payouts

Education and eLearning affiliates come next, averaging $15,551 per month in earnings, according to Authority Hacker. Travel follows at $13,847 per month, and beauty at $12,475 per month.

The full breakdown by niche, average commission rate range, and average monthly revenue is shown in the table below:

Niche	Commission Rate Range
SaaS / Software	20% to 70%
Finance / Fintech	35% to 40% (or $50 to $200 flat per lead)
Health & Wellness	3% to 20%
Travel	10% to 15%
Beauty & Skincare	10% to 30%
eLearning / Education	15% to 30%
Retail & Ecommerce	2% to 10%
Fashion (standard)	8% to 12%
Fashion (luxury)	Up to 15%
Home Improvement	2% to 10%
Pet Care	2% to 20%

Affiliate Marketer Earnings & ROI

The most widely cited figure for affiliate marketer earnings comes from Authority Hacker’s survey of over 2,270 affiliate marketers. It found that the average affiliate marketer earns $8,038 per month, which translates to roughly $96,456 per year. 

The same survey found that the average affiliate website earns $149.76 in revenue per 1,000 visitors (RPM), which gives a useful benchmark for estimating income based on traffic.

According to AffiliateWP, 81.2% of affiliate marketers make more than $20,000 annually. While this sounds positive, it is important to read this alongside the data on lower earners. 

Customers who arrive via an affiliate link make 21% more repeat purchases than customers who arrive through other channels.

According to the Influencer Marketing Hub Affiliate Marketing Benchmark Report, 57.55% of affiliate marketers earn less than $10,000 per year. Only 11.18% earn over $100,000 per year, and just 3.78% earn over $150,000 per year.

The table below shows the full annual income distribution among affiliate marketers:

Annual Income Range	Share of Affiliate Marketers
Below $10,000	57.55%
$10,000 to $50,000	16.21%
$50,000 to $100,000	5.15%
$100,000 to $150,000	7.94%
Above $150,000	3.78%
Not disclosed	9.37%

Earnings by Experience Level

Authority Hacker’s survey data shows that affiliate marketers with more than 3 years of experience earn 9.45 times more than beginners. 

Those with over 10 years of experience earn an average of over $44,000 per month, compared to far lower figures for those just starting out.

The income tiers by experience level, commonly referenced across the industry, break down as follows:

Experience Level	Typical Monthly Income
Beginner (under 1 year)	$0 to $1,000
Intermediate (1 to 3 years)	$1,000 to $10,000
Advanced (3 to 10 years)	$10,000 to $100,000
Super Affiliate (10+ years)	$100,000 and above

(Source: Influencer Marketing Hub, Authority Hacker)

The gap between beginners and experienced affiliates is also visible in traffic data. Affiliates with less than one year of experience average around 13,700 monthly visitors to their sites, while those with 3 to 5 years of experience average 67,800 monthly visitors, and those with 10 or more years average 216,000 monthly visitors. 

The typical affiliate marketer has approximately 2.8 years of experience in the industry.

Earnings by Work Structure

77.1% of affiliate marketers work alone, with no team members (Authority Hacker).

Among those who do have teams, the average team size is 2.3 people, and around 17% of affiliates have between 2 and 5 team members. Only about 5% of affiliates operate with a team of more than 5 people. 

Affiliate Marketing ROI for Brands

From the brand side, the return numbers on affiliate marketing are consistently reported as strong. Brands using affiliate marketing report an average return of $15 for every $1 spent, which equals a 1,400% ROI. 

Rakuten Advertising, using data from seven major affiliate networks and platforms including Awin, CJ, Partnerize, and ShareASale, reports the average return on ad spend (ROAS) for affiliate marketing at 12:1. 

This means that for every $1 put into affiliate programs, brands receive $12 back in revenue on average. 

65% of retailers say their affiliate programs have increased annual revenue by up to 20%. 20% of brands describe affiliate marketing as their single most successful customer acquisition channel.

Affiliate-acquired customers also show a 15% higher average order value compared to the site average across affiliate networks.

Conversion Rates and Click Performance

Affiliate marketing conversion rates sit between 0.5% and 1% on average across all programs. 

By business model, B2C affiliate programs convert at an average of 2.0%, while B2B affiliate programs average 1.2%. 

In retail and fashion specifically, affiliate conversion rates can reach 4.2%, particularly when coupon and cashback partnerships are involved. Affiliate landing pages built around product reviews achieve 5% to 6% conversion rates, nearly double the rates seen on generic brand pages. 

The click-through rate (CTR) for affiliate links in 2026 typically falls between 0.5% and 1%. Across all affiliates combined, over 5 billion clicks are recorded on affiliate marketing links annually, which result in over 170 million online transactions per year.

The average affiliate website RPM of $149.76 per 1,000 visitors means that traffic quality and niche targeting matter considerably more than raw visitor numbers alone.

Traffic Sources & Consumer Behavior

Organic search is the number one traffic source for affiliate marketers by a wide margin.

78.3% of affiliate marketers use SEO as their primary traffic acquisition method. The dominance of SEO as a traffic source increases with experience. Among affiliates with 3 to 10 years of experience, approximately 90% use SEO as a primary traffic source. Among those with over 10 years of experience, the figure is 84%.

Google’s AI Overviews have reduced click-through rates significantly on affected search results pages. CTRs drop to just 8% when AI Overviews appear, compared to around 15% on pages without them, which represents nearly half the traffic gone from organic positions in some query categories.

As a result, algorithm updates negatively impacted 25.1% of affiliates in 2025, and of those affected, 47.4% changed their content strategy in response.

Traffic Source Breakdown Across All Affiliates

Beyond SEO, affiliates use a range of channels to drive traffic.

Traffic Source	Share of Affiliate Marketers Using It as Primary Source
Organic SEO	78%
