Amazon New Product Launch Analytics
Track new ASIN performance with a 3-phase scorecard. Detect cannibalization, set kill thresholds, and measure true launch ROI inside large portfolios.
Gemini
ChatGPTYou launched 12 products last year. How many actually earned their shelf space after 90 days? If you can't answer that question with specific numbers, you're not alone. Most portfolio sellers track launch spend and launch revenue, but not launch ROI relative to the rest of their catalog.
Launching inside a large portfolio is fundamentally different from launching your first product. You have existing products that could be cannibalized. You have portfolio-level TACoS that the new ASIN's ad spend affects. You have opportunity costs: every dollar spent on a failing launch is a dollar not spent on scaling a proven winner.
This guide introduces the 90-Day Launch Scorecard: a structured measurement framework that tells you exactly when a launch is working, when it's failing, and when to make the kill-or-scale decision. It includes cannibalization detection, phase-specific benchmarks, and the five "Kill Threshold" signals that save you from sunk-cost escalation.
TL;DR - Key Takeaways
- •Most portfolio sellers can't answer which of their launches actually earned their shelf space after 90 days.
- •The 90-Day Scorecard splits launch measurement into 3 phases: Traction (Days 1-30), Validation (Days 31-60), and Decision (Days 61-90).
- •Cannibalization detection matters more than standalone metrics. Track portfolio-level TACoS alongside new ASIN performance to catch substitution effects.
- •Five 'Kill Threshold' signals tell you when to pull the plug before sunk costs escalate into serious losses.

The 90-Day Launch Scorecard
The scorecard divides your first 90 days into three phases, each with different success criteria. Evaluating a Day 15 product against Day 75 benchmarks leads to premature kills. Evaluating a Day 75 product against Day 15 expectations leads to sunk-cost traps.
Phase 1: Traction (Days 1 to 30)
Goal: Prove initial demand exists
You're not looking for profitability. You're looking for signal. Can this product attract sessions? Can it convert those sessions at a reasonable rate? Is the review engine working?
| Metric | Target | Red Flag |
|---|---|---|
| Daily Sessions | 50+ (category dependent) | Under 20 by Day 14 |
| Conversion Rate | 8%+ stabilizing | Under 5% and volatile |
| Reviews | 5-10 by Day 30 | Zero reviews by Day 21 |
| ACoS | Under 80% (launch mode) | Over 120% with no improvement trend |
Phase 2: Validation (Days 31 to 60)
Goal: Confirm demand is sustainable and improving
Traction proved the product can sell. Validation proves it can sell efficiently. You're looking for positive trends: declining TACoS, improving organic share, and revenue growth week-over-week.
| Metric | Target | Red Flag |
|---|---|---|
| Week-over-Week Revenue | Growing 5-15% | Flat or declining by Week 6 |
| TACoS Trend | Declining from launch peak | Still rising at Day 45 |
| Organic Sales Share | 15-25% and growing | Under 10% with no upward trend |
| Reviews | 15-25 total, 4.0+ rating | Under 10, or rating below 3.8 |
Phase 3: Decision (Days 61 to 90)
Goal: Make the keep-or-kill decision with data
By Day 61, you have 2 months of data. Enough to see trends, not just snapshots. The question is simple: is this product on a trajectory to reach breakeven contribution margin within the next 60 days?
| Metric | Scale Signal | Kill Signal |
|---|---|---|
| Contribution Margin | Approaching breakeven | Still deeply negative, no improvement |
| TACoS | Under 25% and declining | Over 30% with no improvement |
| Organic Share | 30%+ of total sales | Under 15% |
| BSR | Stabilizing in target range | Erratic or worsening |
Cannibalization Detection
This is where portfolio sellers need a different lens than single-product sellers. A new ASIN might look successful in isolation: growing revenue, decent conversion rate, reviews building. But if your portfolio revenue stays flat or declines during the same period, the new product may be stealing from your existing catalog.
Three Cannibalization Signals
- Portfolio revenue stagnation: Total portfolio revenue doesn't grow proportionally to the new ASIN's revenue. If you launch a product doing $10K/month but portfolio revenue only grows $3K/month, roughly $7K is substitution.
- TACoS creep at portfolio level: your portfolio TACoS increases beyond what the new ASIN's ad spend would explain. This means existing products are losing organic momentum.
- Sibling ASIN decline: Products in the same category or parent ASIN family show declining sessions or conversion rates after the launch.
Use Custom Breakdowns to create a "Launch Cohort" view that isolates new products. Then compare portfolio performance with and without the launch cohort to spot substitution effects.
The Kill Threshold Framework: 5 Signals
The hardest part of launching isn't spending money. It's knowing when to stop. These five signals, when observed together, indicate a launch that won't recover:
| # | Signal | When to Check | What It Means |
|---|---|---|---|
| 1 | Conversion rate below 5% after Day 30 | End of Phase 1 | The listing doesn't resonate. More ad spend won't fix a listing problem. |
| 2 | Zero organic sales by Day 45 | Mid Phase 2 | Ads are the only demand source. No organic flywheel is forming. |
| 3 | TACoS still rising at Day 45 | Mid Phase 2 | You're spending more per dollar of revenue, not less. The efficiency curve is wrong. |
| 4 | Fewer than 10 reviews by Day 60 | End of Phase 2 | Review velocity too slow to build social proof. Competitors with 500+ reviews will always win the click. |
| 5 | Portfolio cannibalization detected | Any phase | The new product is growing your costs without growing your portfolio. |
Any single signal warrants investigation. Three or more signals together warrant a kill decision. Don't wait until Day 90 if signals 1, 2, and 3 are present at Day 45. That's $4K to $8K in additional losses you can avoid.
Setting Up Launch Tracking in Nova
The implementation uses three features working together:
- Custom Breakdowns: Tag new products with "Launch" and the launch date. This creates a filterable cohort for all launch metrics.
- Custom Breakdowns: build a "Launch Cohort" view that shows launch products against portfolio averages. This is your cannibalization detection dashboard.
- Winners and Losers: Surface which launches are trending up (scale candidates) vs. Trending down (kill candidates) in real time.
Track each launch product against the phase-specific benchmarks in the tables above. When a product clears Phase 3 successfully, graduate its tag from "Launch" to "Growth" and shift it into your lifecycle management Framework.
Real Example: 8 Launches, 3 Killed, 2 Scaled, 3 Pivoted
Home goods brand, 350-SKU catalog, H1 2025 launch batch
A home goods brand launched 8 new products in Q1 2025 with a total launch budget of $95K (inventory plus ad spend). Using the 90-Day Scorecard:
- 3 killed at Day 45: all three had conversion rates below 4% and zero organic sessions. Total loss: $18K. Without the scorecard, these would have run through Day 90, costing an estimated $38K.
- 2 killed at Day 90: One showed cannibalization of an existing best seller. The other never achieved organic traction despite 20+ reviews. Total loss: $22K, but early detection saved roughly $15K vs. Running to 6 months.
- 3 scaled: these products cleared all Phase 3 benchmarks. Combined, they generated $142K in revenue in months 4 to 6 with 22% contribution margin. By month 9, they accounted for 8% of portfolio profit.
Net result: $95K invested, $40K lost on 5 kills (saved an estimated $53K by killing early), and $31K in contribution margin from the 3 winners in their first 6 months. The winners alone paid back the entire launch batch within 9 months.

How Launch Analytics Fits Your Portfolio Strategy
Launch measurement is one piece of the broader portfolio management system:
- Pre-launch: Use portfolio segmentation to identify gaps worth filling.
- During launch: Apply the 90-Day Scorecard with daily dashboard monitoring.
- Post-launch success: Graduate to lifecycle stage management and catalog profit optimization.
- Post-launch failure: Apply SKU rationalization to extract remaining value and reallocate capital.
- Seasonal launches: Use the seasonal portfolio planning Framework to time launches for maximum impact.
