Getting the most out of your advertising budget is an ongoing challenge, so marketers need to examine their specific goals when divvying up their budgets. While Google Paid Search tops overall return on ad spend (ROAS) in 2021 at 13.76, up 31% year-over-year, Amazon offers the most efficient cost-per-click at $0.39 and Instagram boasts the highest conversion rate, at 8.07%.
Category matters too: apparel retailers can find the lowest cost per acquisition on Facebook, at $6.17, while the highest ROAS for computers and electronics was 9.91 on Google Shopping. In comparison, house and home retailers earned a 17.42 ROAS on Instagram.
