Affiliate Marketing Statistics 2026: 10 UK Data Points
Affiliate marketing statistics 2026: 10 UK data points on spend, revenue, clicks and ROI, with scope notes to guide your next program decision.
What Should You Compare Before Choosing?
Affiliate marketing statistics 2026 are most useful when the reader knows what market, year, and measurement they describe. The strongest current source is the APMA's State of the Affiliate Nation research, published in 2026 from data about UK affiliate and partner activity in 2025.
The report points to a sizeable channel: about £1.78 billion invested, 357 million tracked transactions, and 14.8 billion tracked clicks. Those figures describe reported industry activity, not a forecast for every publisher or a promise that a particular affiliate program will deliver the same return.
Quick answer: The APMA reports that UK affiliate and partner marketing grew 7.3% in 2025. Its public findings also report £20.7 billion in revenue, a 15:1 return overall, a 19:1 return in travel, and more affiliate-attributed spending during Cyber Weekend. Treat these as UK market context and check the definition beside each number before applying it.
| Measure | APMA's reported figure | Safe interpretation |
|---|---|---|
| UK channel investment | £1.78bn | Reported 2025 spend, rounded publicly to £1.8bn |
| Tracked transactions | 357m | Annual total, not a typical program conversion rate |
| Tracked clicks | 14.8bn | Click activity, not unique visitors |
| Industry growth | 7.3% | UK affiliate and partner sector growth in 2025 |
| Reported return | 15:1 overall, 19:1 in travel | A market estimate, not an individual earnings promise |
What affiliate marketing statistics 2026 actually measure
The 2026 publication summarizes 2025 UK affiliate and partner marketing data. APMA says 11 network and platform businesses contributed company data, which it aggregated to describe the channel. The free highlights report is public, while the full report is for members.
That source design matters. The findings do not represent every network, brand, country, publisher, or commission model. APMA's public article describes the channel as UK research and explains its broad measures. The APMA report summary and 2026 highlights PDF are the source for the figures below.
Throughout, 2026 refers to the publication date; the observations are from 2025. The figures retain APMA's scope and rounding.
10 UK affiliate marketing statistics for 2026
1. UK brands invested £1.78 billion in 2025
The highlights report lists £1.78 billion invested in UK affiliate and partner marketing during 2025. APMA's news page rounds that to £1.8 billion. Together, the two versions give a useful scale check without suggesting that spending was evenly distributed across sectors or companies.
For a program owner, the amount signals that the channel receives material budget attention in the UK market. For a publisher, it does not say how much a single site can earn. Your result still depends on the audience, product, qualified traffic, conversion path, and the specific partner agreement.
2. The report attributes £20.7 billion in revenue to the channel
APMA reports £20.7 billion in revenue driven by affiliate and partner marketing. The highlights PDF adds a note referring to travel and retail sectors, so do not present this as a universal total for every affiliate business.
Revenue is also different from affiliate commission. It measures sales value attributed to the channel under the report's framework. A publisher estimating its own earnings should use approved conversions and commission records, not multiply this industry figure by a guessed share.
3. UK affiliate and partner activity grew 7.3%
APMA says the UK industry grew 7.3% in 2025, describing it as roughly five times the pace of the UK economy. This is a comparison reported by APMA, not a claim that every merchant's affiliate revenue rose by the same rate.
The useful takeaway is direction: brands continued investing in measurable partnership channels. Program owners still need their own incremental sales, margin, and customer-quality data for budget decisions.
4. Affiliates generated 357 million tracked transactions
The APMA highlights report counts 357 million transactions. The news article converts that annual figure to about 41,000 per hour. The hourly number is a simple annual average, not a claim that activity is flat through every hour, weekday, or shopping season.
This is a scale measure for reported UK tracking. It is not the number of transactions credited to an average publisher. Affiliates should instead check their own click-to-order rate, reversal rate, average order value, and approval rate over a clearly stated date range.
5. The dataset records 14.8 billion affiliate clicks
APMA reports 14.8 billion clicks in 2025, or around 470 per second when averaged across the year. The figure shows how much referral activity the contributing businesses recorded, but it should not be read as 14.8 billion unique people.
A click is an event, not a person or a sale. Repeat clicks, multiple publishers, device changes, and attribution rules affect totals. Pair them with approved transactions and revenue before discussing outcomes.
6. APMA reports a 15:1 return overall and 19:1 in travel
The APMA article describes a 15:1 return on investment across its reported data, rising to 19:1 in travel. These ratios summarize the measurement in the report. They do not establish what a new advertiser will earn after its own margin, product cost, reversals, network fees, and staffing are considered.
Ask how the return is calculated and which costs it includes. Publishers should not turn it into an earnings claim. Build forecasts from approved commission terms, relevant traffic, likely conversion, and a downside case.
7. More than £1 in every £7 of Cyber Weekend spend was tracked through affiliates
APMA says more than £1 in every £7 spent over Cyber Weekend was tracked through an affiliate link, compared with £1 in every £8 the previous year. This indicates a larger observed share during a concentrated retail period.
Peak-weekend data is not an annual benchmark. Publishers should check live offers, dates, restrictions, and inventory before scheduling a seasonal campaign.
8. Retail accounted for 47% of affiliate marketing spend
Retail remained the largest reported sector and represented 47% of spend in the APMA highlights. That describes budget share, not the proportion of every affiliate publisher's revenue that comes from retail.
The figure may help a merchant understand why comparison, cashback, content, and product discovery partners appear in the same market. A publisher should start with reader intent: someone researching a product, starting a store, or comparing software needs a recommendation grounded in that decision.
9. Travel and other sectors showed different patterns of growth
The highlights report says travel spend grew 14% and travel revenue rose 10% year over year. It also notes health and beauty revenue growth of 48%, finance spend growth of 9%, and around one million affiliate-driven telecom customers per month.
These are different sector measures, not one ranking. Before entering a category, check its products, audience economics, traffic rules, and current program terms.
10. Nearly one pound in five was spent outside traditional last-click CPA
APMA says close to one in five pounds of channel spend sat outside traditional last-click cost-per-action models. Its public report points to tenancy, hybrid, content, visibility, and placement arrangements as examples of broader partnership activity.
Program owners should define each partner's job and measurement. Publishers should remember that a referral journey may involve more than one click. Alternative payment models still need clear terms and evidence.
How to apply the numbers to an affiliate decision
Use the statistics to ask better questions, not to skip program research. Match the market to your country and audience, then check conversion events, attribution, approval rules, reversals, eligible traffic, and the work needed to create useful content.
A publisher writing for site owners might compare the SiteGround affiliate program with other hosting options. An ecommerce educator could review the Shopify affiliate program, while an SEO creator might investigate the Semrush affiliate program. These directory listings are examples to research. They are not inputs to APMA's industry dataset, and the approved partner terms remain controlling.
For a wider view, compare this annual refresh with affiliate marketing statistics from 2025 and the 2026 changes AI is bringing to affiliate marketing. They cover different evidence and questions, so keep their dates and source definitions separate.
