100 Affiliate Marketing Spending Statistics for 2026

Before you compare affiliate budgets, check what the money measures. Advertiser expenditure, publisher remuneration and attributed merchant revenue describe different parts of the same transaction chain. Treating them as a single market-size measure produces misleading comparisons.

This guide separates original German market estimates, US performance-marketing research and Australian programme surveys. Each observation keeps its geography and period, while the methodology explains attribution, sample coverage and unresolved source inconsistencies.

How large is German affiliate and partner marketing investment?

Market spending and attributed sales answer different questions. Germany's network-based study supplies both, but their totals should not be turned into an improvised return ratio.

What do German investment and revenue totals measure?

  • German affiliate/partner marketing investment in 2024: €861 million. (BVDW / APMC, Jun 2026)
  • German affiliate/partner marketing investment growth in 2025: 8.3%. (BVDW / APMC, Jun 2026)
  • German affiliate-attributed revenue in 2024: €16.7 billion. (BVDW / APMC, Jun 2026)
  • German affiliate-attributed revenue in 2025: €18.7 billion. (BVDW / APMC, Jun 2026)
  • German affiliate-attributed revenue growth in 2025: 12.0%. (BVDW / APMC, Jun 2026)

The study estimates advertiser investment and affiliate-attributed revenue separately. Its spending definition includes commissions, fixed placements and network or platform costs. Both observation years were gathered in the same collection exercise, supporting an internal comparison. The latest investment headline appears above. The remaining totals preserve the source's accounting distinction: attributed merchant revenue is not publisher commission income. No currency conversion or cross-country total is constructed from these observations.

Which sectors account for German spending?

  • Retail represented 60% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Telecommunications represented 10% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Other represented 10% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Travel represented 8% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Finance and insurance represented 7% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Services represented 4% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Gaming, utilities and similar categories represented 1% of 2025 spend. (BVDW / APMC, Jun 2026)

Retail is the largest sector in the German distribution. The sector classification below concerns advertiser investment across participating networks, instead of consumer preferences or publisher counts. Broad residual groups remain broad: the study's other category should not be assigned to a narrower industry. These shares are a view of the measured channel under its coverage rules. They do not establish affiliate's share of every sector's complete marketing budget.

Which remuneration arrangements dominate German investment?

  • Tenancy/fixed fees represented 6.8% of 2025 remuneration. (BVDW / APMC, Jun 2026)
  • CPL represented 6.5% of 2025 remuneration. (BVDW / APMC, Jun 2026)
  • Other remuneration, including hybrid/CPC/services represented 7.0% of 2025 remuneration. (BVDW / APMC, Jun 2026)

Outcome-based commissions dominate the reported remuneration mix. The leading share is in Main Takeaways; the remaining categories below preserve the report's labels. Tenancy means a fixed placement fee instead of a guaranteed sale. The report's methodology excludes lead-generation activity while its remuneration table includes CPL, leaving a scope ambiguity that readers should retain. We do not treat the CPL line as evidence that every lead-generation product is included in the national estimate. The remuneration categories therefore require the report's original scope qualification.

Which German publisher models receive the spending?

Partner mix is a budget decision, more than a recruitment decision. The German data measures how spending is distributed, instead of how many publishers operate each business model.

Which established publisher types receive German budgets?

  • Content publishers received 13% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Price-comparison publishers received 12.6% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Media-buying partners received 8% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Technology and onsite-optimisation partners received 7.7% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Discount, deals and voucher partners received 7.3% of 2025 spend. (BVDW / APMC, Jun 2026)

Cashback, rewards and card-linked offers lead the reported publisher mix; their current share is in Main Takeaways. The following observations describe spending allocated to other established partner types in the same year. They are not adoption rates or shares of all publishers. Last-click attribution also shapes the visibility of conversion-oriented partners. Budget allocation can therefore reflect both commercial value and measurement rules, instead of independently proving how much incremental demand each model creates.

How much goes to specialist and newer partner models?

  • Influencers and social content received 6.1% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Sub-networks and aggregators received 5.7% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Comparison shopping services received 3.4% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Email publishers received 3.3% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Brand-to-brand partnerships received 1.4% of 2025 spend. (BVDW / APMC, Jun 2026)
  • Other publishers received 10.5% of 2025 spend. (BVDW / APMC, Jun 2026)

The German study separates several specialist publisher models instead of absorbing them into content or discount categories. This makes its partner mix useful for planning, but the categories still follow the study's taxonomy. Sub-networks aggregate access to publishers; comparison shopping services are distinct from general price-comparison sites. The residual category remains unspecified. None of these expenditure shares measures partner profitability, and a small national share does not establish that a model is unsuitable for an individual advertiser.

What did the earlier German publisher allocation look like?

  • Cashback, rewards and card-linked offers received 19.9% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Content publishers received 13.3% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Price-comparison publishers received 11.4% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Media-buying partners received 9% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Technology and onsite-optimisation partners received 7.6% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Discount, deals and voucher partners received 9.5% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Influencers and social content received 5.5% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Sub-networks and aggregators received 6.5% of 2024 spend. (BVDW / APMC, Jun 2026)
  • Email publishers received 4.2% of 2024 spend. (BVDW / APMC, Jun 2026)

These selected historical shares use the same report's earlier-year table. They are comparison points, not a complete distribution, and should not be summed to reconstruct the market. A change in share also differs from a change in absolute spending.

Where is US affiliate investment concentrated?

US spending has broadened beyond retail, but retail remains the largest category. The PMA study supplies a historical series with its own coverage and definitions, not a directly comparable German market estimate.

How has measured US affiliate investment developed?

PMA's national investment series includes commissions and other programme costs, such as placements and technology. The latest amount and compound growth rate appear above; the historical levels below retain their original years. The revenue estimate is an attributed merchant-sales measure, not money received by publishers. This distinction counts when comparing programme budgets with sales returns. The study is dated by publication, while its underlying investment observations describe earlier completed calendar years. These are nominal amounts in US dollars.

What is the current US sector allocation?

Retail takes the largest share of the PMA study's latest measured expenditure. The sector mix below describes affiliate advertising investment within the US study, not each industry's total digital advertising budget. Financial services covers several business models with different conversion and revenue-recognition patterns. Keeping that definition visible prevents its share from being confused with the spending of banks alone. The residual category is left intact instead of assigned to an unsupported niche.

What do historical US sector comparisons establish?

The PMA chart reports retail losing share while finance and travel gain share relative to the earlier comparison. The historical entries below reproduce those individual source values without normalisation. The complete historical chart totals more than a full distribution, which is a source inconsistency; the methodology note records it explicitly. These selected points therefore should not be used to reconstruct a precise earlier-year allocation or calculate dollar spending by sector. The latest distribution is reported separately. Neither column establishes causal changes in advertiser demand.

What returns does US affiliate retail spending generate?

These retail returns describe 2024. Sales return is not profit return. Retail subsector differences are useful planning context, but attributed sales alone cannot establish that an affiliate placement caused a purchase.

Which US retail categories show the highest sales returns?

Department stores lead the reported retail sales-return chart, with the headline observation in Main Takeaways. The other categories below retain the source's attributed-sales-per-dollar definition. A high ratio can coexist with thin margins, returns or fulfilment costs, none of which this chart resolves. It also does not distinguish purchases that would have happened without the affiliate exposure. The comparison is a category benchmark from participating data, not a guaranteed return for a new programme.

What do household and personal retail categories return?

The middle of the retail chart still spans different shopping behaviours and order values. These observations describe the latest measured year, including categories for which the report does not display an earlier comparison. Missing historical bars are not zero returns. Attributed sales should remain separate from contribution margin and publisher earnings. A programme manager comparing these ratios would also need consistent commission treatment, returns handling and attribution windows before drawing conclusions about relative profitability.

How do lower reported sales-return categories compare?

The lower end of the PMA chart is still a sales multiple, not a net-profit margin. The food-and-drink observation appears in Main Takeaways; the remaining categories below retain the same expenditure denominator. Product economics and purchase frequency can differ substantially across these groups. The chart cannot identify the share of customers acquired incrementally, so it should support further commercial analysis instead of replace it. Nor does a lower category average establish that every publisher partnership underperforms.

How large are Australian affiliate budgets and revenue contributions?

These responses describe the 2026 survey. A respondent budget distribution is not a national market size. Australia's survey reveals the range of programme economics while explicitly warning that its sample changes between editions.

What monthly spending brackets do Australian respondents report?

  • 3% reported monthly gross spending of under $1,000. (IAB Australia, Apr 2026)
  • 7% reported monthly gross spending of $1,000–4,999. (IAB Australia, Apr 2026)
  • 16% reported monthly gross spending of $5,000–9,999. (IAB Australia, Apr 2026)
  • 20% reported monthly gross spending of $10,000–49,999. (IAB Australia, Apr 2026)
  • 23% reported monthly gross spending of $50,000–99,999. (IAB Australia, Apr 2026)

The IAB question asks about gross monthly affiliate and partnership expenditure. Agencies estimate average expenditure per client, so their answers are not total agency billings. The top bracket is in Main Takeaways, with the other brackets below. Dollar labels are retained exactly as the Australian report presents them and are not converted into US currency. The sample describes surveyed advertisers and agencies; it is not a probability estimate of every business operating an affiliate programme.

How much advertiser online revenue comes through partnerships?

  • 26% of advertiser/agency respondents selected "5% or less". (IAB Australia, Apr 2026)
  • 15% of advertiser/agency respondents selected "More than 16%". (IAB Australia, Apr 2026)
  • 11% of advertiser/agency respondents selected "Don't know/not sure". (IAB Australia, Apr 2026)

Respondents report the channel's contribution to their own or their clients' online revenue. This is a share of business revenue, not a share of advertising spend and not a national market estimate. The central bracket appears above. The remaining response labels preserve the original survey wording, including its unusual upper-bracket boundary. We do not silently redefine that category. A respondent's uncertainty is also reported separately instead of treated as a zero contribution. Self-reported revenue contribution does not independently validate the underlying attribution model.

How dependent are publishers on affiliate revenue?

  • 18% of publishers selected "Up to 9%". (IAB Australia, Apr 2026)
  • 8% of publishers selected "10% to 24%". (IAB Australia, Apr 2026)
  • 6% of publishers selected "25% to 49%". (IAB Australia, Apr 2026)
  • 16% of publishers selected "50% to 74%". (IAB Australia, Apr 2026)
  • 29% of publishers selected "75% or more". (IAB Australia, Apr 2026)
  • 22% of publishers selected "Don't know". (IAB Australia, Apr 2026)

Publishers report a different revenue denominator from advertisers: the online revenue of their own company. The survey separates several dependency brackets and an explicit unknown response. These shares therefore should not be combined with the advertiser distribution or used to estimate merchant sales. The sampled publisher mix varies between annual studies, limiting strong trend claims. Rounded responses can also leave the displayed distribution slightly short of a complete total without implying a missing business category.

How do Australian affiliate programmes pay partners?

Payment-model popularity does not tell you where the money goes. Australian respondents can use several models, so these results measure usage instead of expenditure shares.

Which payment models do advertisers and agencies use?

  • Tenancy fees were used by 54% of advertiser/agency respondents. (IAB Australia, Apr 2026)
  • CPC were used by 40% of advertiser/agency respondents. (IAB Australia, Apr 2026)
  • Goal-based partner bonuses were used by 20% of advertiser/agency respondents. (IAB Australia, Apr 2026)
  • CPL were used by 14% of advertiser/agency respondents. (IAB Australia, Apr 2026)
  • CPM were used by 12% of advertiser/agency respondents. (IAB Australia, Apr 2026)

The advertiser and agency question allows multiple payment models. Commission use appears in Main Takeaways; the remaining options below measure the proportion selecting each model. A programme can pay both a placement fee and a commission, so adding the percentages would not produce a spending distribution. Bonuses describe conditional incentives instead of a separate universal pricing standard. These results reveal contractual variety, but not the amount paid under each agreement or the effectiveness of each remuneration approach.

Which payment models do publishers receive?

  • CPA commissions were used by 86% of publisher respondents. (IAB Australia, Apr 2026)
  • CPC were used by 47% of publisher respondents. (IAB Australia, Apr 2026)
  • Tenancy fees were used by 39% of publisher respondents. (IAB Australia, Apr 2026)
  • CPM were used by 24% of publisher respondents. (IAB Australia, Apr 2026)
  • CPL were used by 20% of publisher respondents. (IAB Australia, Apr 2026)
  • Goal-based partner bonuses were used by 10% of publisher respondents. (IAB Australia, Apr 2026)

Publisher responses use their own survey base and cannot be paired directly with the advertiser sample as matched transactions. The options describe forms of payment used through affiliate partnerships, with multiple selections allowed. The report notes that its publisher sample includes many smaller businesses, which affects how the tenancy result should be interpreted. Historical publisher results were restated to exclude unknown responses. The observations below use the current edition's values, preserving that study-specific treatment.

How common is stable spending in Australian programmes?

  • 39% of Australian advertiser/agency respondents expected affiliate/partnership spending to stay the same over the following year in the 2026 survey. (IAB Australia, Apr 2026)

Stable budgets are a distinct response, not evidence that a channel is absent or failing. The reported past-year stability result is in Main Takeaways; the forward-looking response below concerns expectations expressed at survey time. An intention is not a completed budget decision, and the survey does not track whether each respondent subsequently follows through. Agencies again answer with reference to client activity. Neither stability measure should be used to infer flat national expenditure, because sample composition, programme sizes and respondent weighting differ from a market-spending census. Expectations can also change after the original survey closes.

Methodology and sources

Every figure on this page comes from the organisation that produced it: regulators, statistics offices, public bodies, research institutes, and companies reporting their own data or surveys. Each one links to the original report or dataset and carries its release date. Survey results keep their population and fieldwork period, and financial figures keep the measure the producer used. Figures from different producers are not added together or ranked against each other. The page is reviewed monthly and updated when a producer releases newer data.
