1) Amazon Marketing Stream (AMS) provides advertisers with product and campaign performance data in near real-time, allowing for more dynamic bidding and budget adjustments. 2) The document recommends analyzing AMS data over 60, 30, and 14 day periods to identify performance patterns. Rules can then be created to increase or decrease bids during identified high- or low- performing time periods. 3) Implementing AMS-based rules for dynamic bidding and budgeting can result in increased sales, improved conversion rates and costs-per-acquisition, and better control over advertising spending and margins. Regular adjustment and evaluation of rules is important for ongoing optimization.
