What Changed in Amazon Marketing Cloud
Amazon Marketing Cloud (AMC) is Amazon's analytics platform that gives advertisers access to anonymized customer journey data. Until recently, the purchase history window in AMC was capped at 13 months, which significantly limited analytical depth. Now Amazon has extended purchase data access to 5 years, fundamentally changing how teams approach audiences and budgets.
Why 5 Years Matters
13 months didn't even cover a full annual cycle with seasonality. A five-year horizon reveals real patterns: how customers repurchase, how their order value shifts, when they churn and return. For teams working on retention and LTV, this is a different level of data entirely.
Six Use Cases Worth Testing
- Acquisition budget setting. With five-year history, you can more accurately estimate what it truly costs to acquire a customer who stays, not just buys once.
- Identifying high-value customers. Long-term data helps separate one-time buyers from those driving sustainable revenue.
- Retargeting beyond 13 months. Audiences previously considered "lost" become reachable again.
- Seasonal pattern analysis. Five years provide statistically meaningful views of holidays, sales events, and slumps.
- LTV forecasting. Longer history improves the accuracy of customer lifetime value models.
- Campaign impact measurement. Long-term ad effects become measurable rather than hypothetical.
Market Context
For Russian-speaking specialists running Amazon through international accounts, AMC access requires proper setup and awareness of platform limitations. But the trend is clear: Amazon and other major ad ecosystems (Google, Meta) are moving toward longer attribution windows and richer data. Media buyers and affiliates should view AMC not as a niche brand tool, but as a source of insight into traffic quality and buyer behavior.
Our Take
Extending the dataset to five years isn't just a technical update — it's a paradigm shift. Advertisers can now build long-horizon strategies instead of chasing last-click wins. For data-savvy teams, this is a real competitive edge. Everyone else will have to catch up.
