How Big Is the Affiliate Marketing Industry?
Global Market Size and Valuation
The affiliate marketing industry size has grown steadily over the past several years and shows no sign of slowing.
As of 2024, the global market was valued at $18.5 billion. By 2031, forecasts put that figure at $31.7 billion, representing a compound annual growth rate that varies meaningfully by region.
As described on Wikipedia affiliate marketing page, affiliate marketing is a performance-based model where affiliates earn a commission for each visit, signup, or sale generated for a merchant a structure that has made it especially scalable for brands across industries.
Europe is expected to grow at a CAGR of 6.5% between 2024 and 2031. Asia is tracking faster at around 10%. Latin America, the Middle East, and Africa are projected to exceed 7% CAGR, though these markets are still relatively small collectively accounting for less than 10% of global affiliate revenue.
In practice, the bulk of global affiliate revenue is still concentrated in North America, Europe, and parts of Asia. Growth in emerging markets is real but starting from a low base.
Affiliate Marketing Spending in the United States
The US remains the dominant market. Spending crossed $9.56 billion in 2023 and is projected to reach nearly $12 billion in 2025 the first time it will surpass the $10 billion threshold.
The table below shows the full projection through 2028, based on data from Statista affiliate marketing spending tracker.

Growth rates are gradually decelerating not because the market is struggling, but because it's maturing. A market growing at double digits from a near-$10 billion base is still expanding fast by most standards.
Affiliate Marketing Spend in the UK and Other Regions
The UK is the second most active market by spend and data availability. Affiliate marketing spend there grew 17% year-over-year from 2022 to 2023.
A survey by the Affiliate and Partner Marketing Association (APMA) found that over 50% of UK brands want to increase their affiliate channel investment further in 2025.
Interestingly, over 70% of Australian companies and digital marketing agencies run affiliate programs targeting overseas markets with roughly 60% of those focusing on the US.
Affiliate Marketing Adoption by Businesses
How Many Brands Use Affiliate Marketing?
Adoption is high. According to Rakuten, 81% of brands use affiliate marketing programs. That's not a niche tactic anymore it's mainstream.
What's often overlooked is that 94% of publishers use multiple affiliate programs simultaneously, which means the competitive pressure for brands to offer attractive terms is real.

75% of marketers report their affiliate programs as either successful or highly successful. That's a strong outcome for any marketing channel.
Teams commonly report that affiliate marketing takes longer to optimize than paid channels the relationships, content, and trust signals build over months, not weeks. But once running well, the cost-efficiency is difficult to match.
How Affiliate Marketing Compares to Other Channels
According to a 2024 Forrester report, marketers rank affiliates as one of their most effective channels sitting just behind content marketing and PPC, and ahead of email marketing, SEO, social media influencers, and mobile push notifications.
Around 80% of marketers in a Digiday survey said affiliate marketing is becoming more important to their revenue strategy.
Despite this, only 7% of marketing managers globally budget for affiliate marketing as their top priority. The channel is trusted, but still under-resourced relative to its performance.
Affiliate Marketing Revenue and ROI Statistics
Return on Investment
Affiliate marketing ROI figures consistently appear across research: brands average $15 in return for every $1 spent. That's a 1,400% return on investment. Worth noting this is an average across multiple studies and campaign types, not a guarantee for any single program.
Results vary considerably based on niche, commission structure, and publisher quality.
65% of retailers report that their affiliate programs increased annual revenue by up to 20%, according to Awin.
And 16% of ecommerce sales in the US and Canada are attributed to affiliate marketing, according to data from Pepperjam and Statista.
Contribution to Overall Sales and Repeat Purchases
Between 5% and 25% of major brands' overall sales come through affiliate channels. The range is wide which reflects how differently businesses structure and invest in their programs.
One underappreciated metric: customers who arrive via affiliate publishers repeat purchases at a 21% higher rate than those who arrive through other channels. That's not just acquisition value it's retention value.
In the UK, the affiliate channel is estimated to drive one in ten pounds spent online in the retail and ecommerce sector.
If you're thinking about how to manage and allocate marketing budgets effectively alongside affiliate programs, understanding budget planning tools like GoMyFinance can offer useful context for tracking spend against returns.

Most Profitable Niches for Affiliate Marketers

Click bots and fake traffic have risen 33% since 2022, with fraud estimated to cost $71 billion in advertising spend. These aren't abstract risks teams managing active affiliate programs commonly report spending meaningful time on fraud detection and traffic quality review.
In the UK specifically, around 52% of publishers reported losing traffic and commissions in 2024, with search algorithm changes as the primary cause. Of those negatively affected, 47.4% changed their content strategy in response.
Commission Structures and Budget Pressures
46% of marketers globally cite commission structures and sustainable rates as a major challenge. 18% say better tracking and reporting tools would be the single biggest reason to increase their affiliate spend.
Another 17% struggle to find well-aligned partners, and the same proportion cite a lack of expert support.These numbers point to a recurring theme in the affiliate marketing challenges conversation: the channel requires more active management than it sometimes gets credit for.
Interestingly, this mirrors patterns seen in other performance-driven fields including areas like executive coaching, where structured support and accountability consistently improve outcomes.
The Future of Affiliate Marketing
Spending and Investment Outlook
Affiliate marketing trends point clearly toward continued growth. In the UK, 57% of marketers plan to increase their affiliate spend, and 40% plan to maintain current levels meaning only 3% are pulling back.
US spending is forecast to reach $15.80 billion by 2028, up from $9.56 billion in 2023.
78% of senior marketers globally said in a 2023 Forrester report that they planned to grow their affiliate programs. That intention appears to be translating into actual budget movement.
AI and Emerging Tactics
Nearly 79.3% of affiliate marketers have adopted AI-driven content creation tools. That's a high adoption rate but what's interesting is that publishers don't necessarily rank AI as their top strategic priority.
In surveys of financial services publishers, video content and email marketing ranked higher as future tactics than AI or user-generated content.
That gap between tool adoption and strategic prioritization suggests most affiliate marketers are using AI operationally to speed up content production rather than building it into their core strategy yet. That may shift as the tools develop.
90% of marketers using short-form video plan to increase or maintain that investment. TikTok, YouTube Shorts, and Instagram Reels are increasingly relevant traffic channels for affiliate content.
Conclusion
Affiliate marketing is a large, growing, and measurably effective channel — but also one that requires real investment to run well. The numbers show strong ROI potential alongside real challenges around fraud, tracking, and publisher relationships. Growth will continue, but the gap between programs that are managed actively and those that aren't is only widening.
