What key capability does Report Builder provide for advertisers managing multiple accounts?

Report Builder's primary advantage for advertisers managing multiple accounts is its ability to generate unified reports. This means you can combine performance data from both Sponsored Ads and Amazon DSP across a large number of accounts (up to 700). This provides a holistic view of your advertising efforts, enabling comprehensive analysis and optimization across your entire portfolio. While it can create reports for individual accounts, its key capability for multiple accounts is the unified reporting. Exporting data to third-party platforms is a separate function and not its core multi-account reporting strength.
