Which Pinterest product should an advertiser use to measure its return on ad spend (ROAS) for both organic and paid efforts on Pinterest?

Pinterest Analytics is the correct choice because it provides comprehensive data on both organic and paid performance, including conversions and revenue, which are essential for calculating ROAS. It allows advertisers to track key metrics, understand audience behavior, and measure the effectiveness of their campaigns directly within the platform. Pinterest Trends focuses on search trends and popular topics, not individual ad performance or ROAS. Pinterest Predicts is an annual report forecasting future trends, not a measurement tool. The Pinterest API allows for programmatic access to data but requires custom development to build a ROAS measurement solution, whereas Pinterest Analytics offers this functionality natively.
