What role does Amazon play in streaming TV and retail media advertising?
Amazon DSP offers Canada's largest streaming TV audience, with Prime Video ads generating $3.9B in revenue from 315M viewers. Related strategies include unified reporting via Amazon Marketing Stream and B2B retail media playbooks for brands.
What evidence shows incremental lift from CTV and retail media campaigns?
Universal Ads pizza test demonstrated 3.2% incremental lift, while Smartly and Roku achieved 5.5x ROAS in bridging social to CTV. Viant-Ad Fontes targeting and Chewy's retail media playbook provide additional practical guidance.
