\r\n\r\nDefinition:<\/b>\r\n\r\nCost aggregation is the process of collecting ad spend data from multiple advertising networks and consolidating it into a single view. It allows mobile UA teams to see total campaign spend across all sources, compare network performance side by side, and connect cost data with attribution outcomes to calculate ROAS, CPI, and other key efficiency metrics.\r\n<\/span>\r\n\r\n<\/div>\r\n \r\n

What is Cost Aggregation?<\/b><\/h2>\r\nCost aggregation is the process of collecting and consolidating ad spend data from multiple advertising networks, platforms, and channels into a single, unified view. For mobile user acquisition teams, cost aggregation makes it possible to see total campaign spend across all sources without logging into each ad network separately or manually compiling data from multiple reports.<\/span>\r\n\r\nWithout cost aggregation, teams often work with fragmented spend data. Each network reports its own numbers in its own format, which makes it difficult to compare performance, calculate blended ROAS, or understand where budget is actually going across a full portfolio of campaigns.<\/span>\r\n

How Cost Aggregation Works<\/b><\/h2>\r\nCost aggregation typically works through one of two methods:<\/span>\r\n\r\nAPI-based aggregation:<\/b> The analytics or attribution platform connects to each ad network's API and pulls cost data directly. This is the most reliable approach because the data is pulled programmatically and updated regularly without manual input.<\/span>\r\n\r\nManual or file-based import:<\/b> Teams export cost reports from each network and upload them to a central platform. This approach works but requires ongoing manual effort and is more prone to gaps or delays.<\/span>\r\n\r\nMost modern mobile measurement partners (MMPs) and analytics platforms support API-based cost aggregation, pulling data from networks like Meta, Google, Apple Search Ads, ironSource, Unity, and others into a single dashboard.<\/span>\r\n

Why Cost Aggregation Matters<\/b><\/h2>\r\nMobile UA teams typically run campaigns across many networks at the same time. Without a consolidated cost view, it becomes very difficult to:<\/span>\r\n
