Product Updates

  • External ID support
    • We’re introducing External Item ID (e.g., SKU) Support in MCM to make campaign setup more intuitive for advertisers managing products by their own internal codes. Once enabled, advertisers can select items, upload CSVs, and view reports using their external IDs instead of platform-specific item_ids, streamlining workflows and reducing mapping errors.
  • Inventory Access Customization
    • Platform Owners can now customize Advertiser access to ad types, placements, and inventories within Campaign Manager. This update introduces inventory-level configuration, along with filtering and bulk-edit tools that make managing access fast and scalable. Platform Owners can control which Ad Accounts have access to specific ad types (e.g., Sponsored Products, Sponsored Display, Sponsored Brands), configure access to placement types (such as Cart, Search, or Checkout), and determine which accounts can bid into premium or specialized inventory. Access can be managed universally, by Label, or at the individual Ad Account level. Campaign configuration is streamlined accordingly - ad type options and placement targeting automatically adjust based on the inventory available to each Advertiser.
  • ACOS support in reports
    • We’re introducing ACOS (Advertising Cost of Sales) as an optional reporting metric in MCM. With ACOS, advertisers can assess efficiency and margin impact more intuitively, complementing existing ROAS insights. The metric appears across trend charts, report tables, and CSV downloads once enabled, giving ACOS-preferred advertisers a smoother onboarding experience and clearer profitability signals.
