Data-Driven Attribution [DDA] is a term used by Google Ads. Data-driven attribution gives credit for conversions based on how people engage with your various ads and decide to become your customers. It uses data from your Google Ads account to determine which keywords, ads, and campaigns have the greatest impact on your business goals. Google says: "Data-driven attribution looks at the entire journey that leads a user to convert and allocates credit to each step in that journey."
