The Performance Marketing Association (PMA) released its third triennial affiliate marketing survey, revealing a booming industry. Data from eight networks, 53 publishers, and over 20,000 brands showed ad spend skyrocketing from $6 billion to $13.63 billion (a 14.42% CAGR), exceeding e-commerce growth and contributing 10% to overall US e-commerce revenue. While cashback and coupon sites remain significant, their market share decreased, likely due to the rise of card-linked offers and buy now, pay later options. These, along with influencer marketing, fueled growth, though the overall increase in market size means some sectors saw proportional decreases in share. The survey also highlighted growth in less directly correlated sectors like finance and telecom, and a slight decrease in ROAS (from 12:1 to 11:1), potentially due to a shift towards top-of-funnel traffic. Publisher sentiment shows concern about Google changes but optimism for the future.
