Imagine running ads without knowing how they are performing right now. You launch a new Sponsored Products campaign, and then...you wait. By the time yesterday's reports roll in, your budget may have already burned through peak hours, your best-performing keywords might have been capped too early, and key conversion windows have long passed.
This has always been a frustrating reality of Amazon advertising: reactive decisions based on delayed data.
But lately, Amazon has changed the game.
Amazon Marketing Stream flips the old model by providing hourly, real-time performance data via a push-based API. No more waiting. No more guesswork. With Amazon Marketing Stream, advertisers and sellers can see campaign performance unfold in near real time and finally start optimizing at the speed of the shopper.
This mindful shift isn't just about faster data access. It's about precision, timing, and control. Moreover, it's already reshaping how high-performance brands approach Sponsored Products campaigns.
In this blog, we will break down what Amazon Marketing Stream is, how it works, and how advertisers can use it to unlock smarter bidding and profitable campaigns. In addition, how advertisers pair it with advanced capabilities like granular search-term visibility and dayparting.
What is Amazon Marketing Stream?
Amazon Marketing Stream is a real-time data transmission service for Sponsored Products campaigns. It pushes hourly performance metrics, like impressions, clicks, CPC, sales, and budget status, directly to advertisers via the Amazon Ads API.
Traditional reports can be configured for hourly data, but they require manual download and are updated with a delay. Amazon Marketing Stream automates and accelerates this process through streaming delivery.
Key Metrics Provided by Amazon Marketing Stream:
Hourly campaign performance data: Impressions, clicks, sales, ROAS, etc.
Event-level notifications: When a campaign runs out of budget or re-enters budget.
Time-segmented insights: To evaluate campaign health by the hour
This allows advertisers to see what's working and when, and make adjustments based on real-time patterns.
Why Traditional Reporting Falls Behind
Before Amazon Marketing Stream, advertisers solely relied on bulk reports that only refreshed once daily, often with a delay of 12 to 24 hours. Which meant:
Losing valuable time reacting to underperforming campaigns
Inability to spot and leverage high-converting time windows
Missing out on impressions and conversions due to out-of-budget blind spots
These limitations slowed down decision-making and also restricted advertisers from capturing micro-moments that drive performance.
How Amazon Marketing Stream Works
Amazon Marketing Stream delivers data hourly and in near real time. Meaning, advertisers no longer have to wait until the next morning to find out their campaign performance. They help you in:
Monitoring campaign performance by specific hour
Identifying conversion trends throughout the day
Taking immediate action to optimize budgets, bids, and placements
In order to use Amazon Marketing Stream, advertisers must access it through an Amazon Ads API-integrated platform capable of receiving and processing streaming data in real time.
Benefits of Amazon Marketing Stream
1. Near Real-Time Campaign Visibility
The major advantage of Amazon Marketing Stream is clear: speed. You get to see the hourly updates with minimal delay. This enables smarter, faster decisions, like pausing an underperforming ad set mid-day or boosting the budget for a high-performing one during peak hours.
2. Dayparting
AMS enables data-driven dayparting by surfacing hourly trends. Actual bid or budget adjustments must be implemented via API-based tools or third-party platforms. With hourly breakdowns, advertisers can pinpoint:
What time of day are customers most likely to click and convert
Which hours drain the budget without driving results
When CPCs spike or drop
With these insights, advertisers can automate bid and budget adjustments based on hourly performance patterns.
This level of time-based control can significantly improve ROAS without increasing overall spend.
3. Granular-Level Data
While AMS provides hourly data at the targeting level, deeper insights such as search term performance by hour require additional layering using other Amazon Ads reports.
Granular-level data enables:
Pausing or reducing bids on inefficient queries in specific time slots
Spotting top-converting keywords by hour
Aligning keyword strategy with consumer intent throughout the day
For instance, a search term like "Anti-dandruff shampoo" might convert better in the morning hours, while "hair oil" peaks in the evening. Without granular visibility by hour and search term, those insights stay hidden.
4. Budget Efficiency and Spend Control
Amazon Marketing Stream also sends event-level budget updates, including:
When a campaign goes out of budget
When it re-enters budget
Real-time pacing insights
This enables advertisers to:
Prevent premature budget exhaustion
Redistribute remaining budgets throughout the day
Ensure high-impact hours always have funds available
5. Enhanced Placement Strategy
With hourly performance visibility, advertisers can refine not just when they bid, but where they bid.
For example:
Target Top of Search during high-converting hours for maximum visibility
Shift to the Rest of Search or Product Pages during less competitive times to maintain presence at lower CPCs.
While AMS does not provide placement-level breakdowns, advertisers can still infer when to activate certain placement strategies based on hourly performance trends at the campaign or targeting level.
