The IAB Affiliate Marketing Working Group has published its third annual industry review on the state of affiliate marketing in the Australian market. 

The IAB Australia Affiliate Marketing Working Group conducted surveys at the end of 2020, gathering responses from advertisers and agencies who operate an affiliate program in Australia. The industry report is based on the results of this survey. We want to thank all the agencies and advertisers who participated in the survey, which formed the 2021 Affiliate Marketing Industry Review.   

The 2021 Affiliate Industry Review looks at advertisers and agencies experience, plans and how they value the channel. In terms of investment last year, 68% of the respondents saw an increase in spend in the affiliate channel and 71% of respondents rated affiliate marketing as seven or above out of ten as higher-performing for delivering ROI (Return on investment) compared to other marketing channels. For advertisers and agencies, the main narrative is that the affiliate channel played an important role over the last twelve months, with the results showing increased growth, increased investment and increased engagement in the channel due to COVID-19 and the lockdown. 

Spend changes over the last year


Affiliate Marketing in the last twelve months has demonstrated its importance and value for businesses of all sizes, with over 69% of brands reporting a positive impact during the lockdown and 68% reporting increased revenue performance during the COVID period. 



2020 has shown that the affiliate channel is invaluable and provides an opportunity for businesses to focus and expand on in 2021. With affiliate marketing reported to deliver higher value, when looking at customer acquisition and ROI metrics of advertisers and agencies, the affiliate channel looks to be here for uncertain times and beyond.  

"The latest Affiliate Marketing Australian Industry Review clearly highlights marketers intent to increase investment in affiliate and partnership marketing with detailed information on models used in the market, investment returns, measurement techniques and market readiness for replacing 3rd party cookies."

Gai Le Roy, CEO, IAB Australia  

“It’s never been so important to showcase how effective the affiliate channel is for brands in Australia. For the third year running, and in the face of difficult circumstances, we’ve seen overall growth & significant perceived value from advertisers involved in affiliate & partnership marketing. But this was also an opportunity for the IAB working group to collect feedback on important issues such as the effects of COVID-19, cookie directives, and ways to move the industry forward. We’re pleased with the levels of response this year, and see this study as a great step that will, ultimately, help brands and publishers utilise affiliate marketing to its fullest potential.” 

David Glasgow, Director, Navigate Digital and IAB Affiliate Marketing Workgroup Chair
