Why You Need to Know the Latest Affiliate Marketing Statistics
Most affiliate marketing growth statistics and ‘facts’ are outdated. If you're using these industry statistics for strategic decision-making, having the most recent information is crucial for planning to start an affiliate program or researching how to recruit affiliates.
The SaaS industry also keeps changing faster than most of us can keep up. For instance, the 2020 pandemic disrupted the affiliate market, causing travel sales to decline while home goods sales increased. By 2024, as we moved beyond the pandemic, market trends continued to evolve.
Now, as we approach 2027, the developments in AI-powered affiliate marketing highlight the need for verified information and stress the importance of building human connections with customers and affiliates.
Affiliate Industry Market Size and Growth Stats
1. The Global Affiliate Marketing Platform Market is Worth $23.8 Billion in 2026
Grand View Research estimates that the global affiliate marketing platform market will grow from $22.6 billion in 2025 to $23.8 billion in 2026. This figure measures the market for platforms and infrastructure that power affiliate programs, rather than total advertiser spending or affiliate-driven sales.
2. The Affiliate Market is Forecast to Reach $35.7 Billion by 2033
The same Grand View Research forecast projects that the affiliate marketing platform market will reach $35.7 billion by 2033. That represents a compound annual growth rate of 5.9% between 2026 and 2033.
3. US Affiliate Marketing Spend Will Reach $13.81 Billion in 2026
US advertisers are expected to spend $13.81 billion on affiliate marketing in 2026, according to EMARKETER. That is an 11.3% increase from $12.42 billion in 2025; and notably faster than the forecast growth of US retail ecommerce during the same period.
4. Affiliate Marketing Will Generate $241.03 Billion in US Ecommerce Sales
Affiliate marketing’s impact is much larger than advertiser spending alone suggests. EMARKETER forecasts that the channel will generate $241.03 billion in US ecommerce sales in 2026.
5. 81% of Advertisers and 84% of Publishers Use Affiliate Marketing
Affiliate marketing is already a standard part of the marketing mix for most brands and publishers. The most widely cited adoption benchmark reports that 81% of advertisers and 84% of publishers participate in affiliate marketing.
6. North America Holds 36% of the Global Affiliate Market
North America accounted for 36% of global affiliate marketing platform revenue in 2025, making it the largest regional market. Its lead reflects the region’s mature ecommerce ecosystem and widespread use of performance-based advertising.
7. Affiliate Marketing Influences Around 16% of US Online Orders
Affiliate marketing is estimated to influence approximately 16% of online orders in the United States. The exact figure varies by methodology, but the benchmark appears consistently across recent industry estimates collected by DemandSage.
Affiliate Marketing ROI and Revenue Statistics
8. Affiliate Marketing Can Return Up to $15 for Every $1 Spent
Affiliate marketing is frequently one of the most capital-efficient acquisition channels because advertisers pay for defined results rather than impressions alone. Industry benchmarks compiled by AffiliateWP report an average return as high as $15 for every $1 invested.
9. Affiliate Campaigns Report an Average ROAS of 12:1
Affiliate campaigns generate an estimated average return on ad spend of 12:1. For context, Google Ads produced an average of $3.31 for every $1 spent in April 2025, according to the figures compiled by DesignRush.
10. 65% of Retailers Attribute Up to 20% of Revenue to Affiliate Marketing
For established programs, affiliate marketing is no longer a small experimental channel. Around 65% of retailers report that affiliate marketing contributes up to 20% of their annual revenue.
11. B2B Affiliate Program Participation Grew 17% in 2025
Affiliate marketing is expanding beyond its traditional ecommerce and consumer-product base. Participation in B2B affiliate programs grew by 17% in 2025 as SaaS and enterprise software companies invested more heavily in performance-based partnerships.
SaaS Affiliate Program Benchmarks
The following findings come from Rewardful’s State of SaaS Affiliate Programs Report. The report analyzed anonymized data from 2,847 SaaS affiliate programs running on Rewardful. Unlike broad affiliate marketing surveys, this data shows what happens inside SaaS programs: from affiliate signups and referrals to commissions, sales, and long-term program activity.
12. 56% of SaaS Affiliate Programs Have Fewer Than 50 Affiliates
More than half of SaaS affiliate programs operate with fewer than 50 affiliates. Nearly one-third have fewer than 10. That does not automatically make them unsuccessful. A smaller group of well-matched and active affiliates can be more valuable than hundreds of partners who never promote the product.
13. Only 10% of Programs Grow Beyond 1,000 Affiliates
Just one in 10 SaaS affiliate programs reaches more than 1,000 affiliates. The steep drop-off suggests that programs rarely scale through passive signups alone. Growth usually requires active recruitment, clear partner positioning, and ongoing management.
14. Only 7.6% of Affiliates Generate a Referral
Affiliate enrollment and affiliate activation are two different problems. Only 7.6% of affiliates in the dataset generated at least one referral.
15. Only 1.28% of Affiliates Generate a Sale
The funnel narrows further when revenue is considered. Only 1.28% of affiliates generated at least one sale. The benchmark makes a strong case for prioritizing partner quality and activation over total signup numbers.
16. The Average SaaS Affiliate Commission Rate is 24.16%
The average commission rate selected by SaaS affiliate program managers is 24.16%.
Most programs cluster within a relatively narrow 20% to 30% range. Programs offering less often compete through brand recognition or product demand, while newer programs may use higher commissions to attract attention.
17. 96.4% of SaaS Commissions Are Percentage-Based
Revenue share is overwhelmingly the preferred commission model for SaaS. Rewardful’s data shows that 96.4% of commissions are calculated as a percentage of the sale. Only 3.6% use a fixed commission amount.
18. The Average SaaS Affiliate Payout Is $14.10
Across the programs analyzed, the average payout per commission is $14.10. The all-time average is slightly lower at $13.56, suggesting that the typical value of an individual SaaS commission has remained fairly consistent.
19. The Average Referral-to-Sale Conversion Rate is 0.8%
Around eight out of every 1,000 visitors referred by SaaS affiliates become paying customers. That is equivalent to an average referral-to-sale conversion rate of 0.8%.
Affiliate traffic does not convert automatically because it came through a trusted partner. Performance still depends on audience fit, message alignment, product positioning, and the strength of the offer.
20. Only 15.6% of SaaS Affiliate Programs Remain Active Long Term
Launching a program is easy. Sustaining it is considerably harder. Only 15.6% of the SaaS affiliate programs analyzed remained active over the long term. Most stalled before affiliate marketing became a consistent and operationally supported growth channel.

AI and Affiliate Marketing Statistics
21. 79.3% of Affiliate Marketers Use AI Content Tools
AI has already become part of the standard affiliate marketing workflow. Around 79.3% of affiliate marketers use AI-driven tools for content creation, according to statistics cited by Hostinger.
Common uses include drafting product reviews, building comparison pages, researching keywords, repurposing content, and testing promotional messaging. The increased output also raises the bar for quality. Content still needs original experience, defensible claims, and a clear reason for readers to trust it.
22. 73% of B2B Buyers Use AI During Purchase Research
Affiliate content is no longer competing for visibility only in traditional search results. A 2026 analysis of B2B research behaviour found that 73% of buyers now use tools such as ChatGPT and Perplexity when researching purchases.
Affiliates that depend on search traffic increasingly need content that can be found, understood, and cited by both search engines and AI systems.
Affiliate Fraud Statistics
23. Digital Ad Fraud Losses Could Reach $172 Billion by 2028
Global losses from digital advertising fraud are projected to reach $172 billion by 2028. Affiliate marketing is among the channels most exposed to fake leads, self-referral fraud, click injection, cookie stuffing, bot traffic, and unauthorized brand bidding.
24. Between 5% and 17% of Affiliate Traffic May Be Fraudulent
Estimates of fraudulent affiliate traffic vary substantially. Recent benchmarks place the share between approximately 5% and 17%, depending on the industry, traffic source, monitoring tools, and definition of invalid activity. Programs without active monitoring may face even higher exposure, according to estimates collected by AffiliateWP and Marketing LTB.
25. 63% of Marketers Are Concerned About Affiliate Fraud
Nearly two-thirds of marketers consider affiliate fraud a significant concern. The 63% figure reported by AffiliateWP shows that fraud is no longer treated as an edge case, although concern does not always translate into real-time monitoring or enforcement.
Mobile and Affiliate Traffic Statistics
26. Mobile Generates 50% of Affiliate Traffic and 70% of Conversions
Mobile devices now account for around half of affiliate traffic and 70% of affiliate conversions, according to Post Affiliate Pro. The gap between traffic and conversions suggests that mobile users arriving through affiliate recommendations often have relatively strong purchase intent.
27. 78% of Affiliates Use SEO as a Primary Traffic Source
Organic search remains the dominant acquisition channel for affiliate marketers. Around 78% identify SEO as a primary traffic source, according to affiliate marketing data compiled by Thunderbit.
That dependence creates both an advantage and a risk. Search can generate compounding traffic, but algorithm changes and AI-generated answers can quickly reduce visibility.
28. Social Platforms Generate 25% of Affiliate Traffic
Around one-quarter of affiliate traffic now comes from social media platforms, including Instagram, YouTube, and TikTok. Thunderbit’s affiliate marketing statistics also indicate that 67% of affiliates rely on social media in some form to drive traffic.
The shift reflects the growing overlap between affiliate marketing, influencer partnerships, and creator-led commerce.
29. TikTok Affiliate Links Achieve a 5.2% Engagement Rate
TikTok influencers generated a 5.2% engagement rate on affiliate links, compared with 2% on Instagram and 0.2% on YouTube. That made TikTok’s engagement rate more than twice Instagram’s and 20 times YouTube’s in the benchmark reported by EMARKETER.
Platform reach alone does not guarantee sales, but higher interaction gives affiliate content more opportunities to influence a purchase.
Affiliate Earnings Statistics
30. The Average US Affiliate Marketer Earns $56,141 per Year
The average salary reported for a US affiliate marketer is $56,141, according to PayScale. Affiliate earnings are highly uneven, however. A relatively small group of established publishers and creators pulls the average upward, while many newer affiliates earn little or nothing.
31. Around 9% of Affiliate Marketers Earn More Than $50,000 per Year
Approximately 9% of affiliate marketers earn more than $50,000 annually from affiliate activity. Income depends heavily on niche, audience size, content quality, traffic sources, program terms, and how long the affiliate has been active.
Creator and Influencer Affiliate Statistics
32. The Influencer Marketing Platform Market Reached $34.2 Billion
The global influencer marketing platform market was valued at $34.2 billion in 2025. Grand View Research expects it to grow to $45.2 billion in 2026 and $116.2 billion by 2033.
That growth is important to affiliate teams because creator and affiliate partnerships are increasingly becoming the same relationship. Brands are combining fixed fees with trackable commissions rather than treating influencer campaigns and affiliate programs as separate channels.
33. Affiliates and Influencers Drove 20% of Cyber Monday Ecommerce Revenue
Influencers and other affiliate marketers generated approximately 20% of US ecommerce revenue on Cyber Monday 2024. The contribution was around 7% higher than in 2023, according to Adobe Analytics data reported by Business Insider.
34. Products Promoted Through Affiliate Links Were Six Times More Likely to Sell
Adobe Analytics also found that products promoted through affiliate links were six times more likely to result in a purchase than products mentioned in social posts without an affiliate or comparable promotional link. As reported by Business Insider, the result suggests that trackable creator recommendations can do more than generate awareness, they can materially shorten the path to purchase.
35. 41% of Gen Z Trusts Influencer-Endorsed Products Over Traditional Ads
Around 41% of Gen Z consumers say they trust products endorsed by influencers more than products promoted through traditional advertising, according to figures compiled by Publift.
For brands targeting younger audiences, the most effective affiliate may not be a large comparison website. It may be a credible niche creator whose audience already trusts their recommendations.
What These Affiliate Marketing Statistics Mean for SaaS Programs
Affiliate marketing is growing, but market growth does not guarantee that an individual program will succeed.
Our data shows where the real challenge lies. Most affiliates never send a referral, and even fewer generate a sale. And most SaaS programs do not remain active long enough to establish reliable payout cycles. The programs that progress beyond that point tend to treat affiliate marketing as an operating channel rather than a signup page. They recruit partners intentionally, give them clear reasons and resources to promote, track activation, and make the path to a first commission as short as possible.
The opportunity is real, but so is the work required to capture it. Rewardful gives SaaS teams the infrastructure to manage that work, with flexible commissions, recurring revenue tracking, two-way Stripe sync, automated commission logic, and managed payouts.
