🔍 Overview
When sales decline on Amazon, the root cause usually falls into one of two categories: not enough traffic or poor conversion. Knowing which problem you actually have is critical, because fixing the wrong one wastes time and ad spend.
In this guide, you’ll learn how to diagnose traffic vs conversion issues using Amazon’s native reports and apply the right fixes with confidence.
👥 Who This Is For
This article is useful if you are:
A new seller unsure why your product isn’t selling despite being live
An FBA seller running ads but not seeing profitable growth
A brand owner launching new ASINs or optimizing existing listings
An advanced seller troubleshooting sudden sales drops or stalled growth
🧠 Key Concepts You Need to Know
Before diagnosing issues, make sure you understand these Amazon metrics:
Sessions
The number of unique visits to your listing.Page Views
Total times your listing was viewed (can include repeat views).Unit Session Percentage (USP)
Amazon’s conversion rate metric.
Formula: Units Ordered ÷ SessionsImpressions
How often your product appears in search results or ads.Click-Through Rate (CTR)
Percentage of impressions that turn into clicks.
Understanding how these metrics interact is the foundation of accurate diagnosis.
🛠️ Step-by-Step Framework: Traffic vs Conversion Diagnosis
1️⃣ Step 1: Check Sessions First (Traffic Baseline)
Go to Business Reports → Detail Page Sales and Traffic by Child Item.
Look at:
Sessions
Page Views
What to look for:
Very low sessions = traffic problem
Stable or high sessions = move to conversion analysis
Common Pitfall:
Comparing today’s sessions to yesterday instead of a 7–30 day range.
💡 Pro Tip:
Always compare performance to a similar time period (weekday vs weekday, promo vs non-promo).
2️⃣ Step 2: Evaluate Conversion Rate (USP)
In the same report, review Unit Session Percentage.
General benchmarks (varies by category):
Below 8% → Conversion issue
8–15% → Needs optimization
15%+ → Healthy conversion
If USP is low while sessions are healthy, traffic is not the issue.
💡 Pro Tip:
Compare your USP to your own ASIN history, not generic benchmarks.
3️⃣ Step 3: Diagnose Traffic Problems (If Sessions Are Low)
If sessions are low, check where traffic should be coming from:
Organic search visibility
Amazon PPC
External traffic
Key checks:
Are your primary keywords indexed?
Is your PPC impression volume declining?
Have you lost Buy Box eligibility?
Common Pitfall:
Increasing ad bids before confirming indexing or Buy Box status.
4️⃣ Step 4: Diagnose Conversion Problems (If USP Is Low)
If traffic exists but sales lag, inspect the listing itself:
Main image quality and compliance
Title clarity and keyword relevance
Bullet points answering buyer objections
A+ Content presence (if brand registered)
Review count and star rating
Pricing vs competing offers
💡 Pro Tip:
Conversion issues are often trust issues, not traffic issues.
5️⃣ Step 5: Confirm with Ads Data (Optional but Powerful)
In Advertising → Campaign Manager, review:
CTR
Conversion Rate
Spend vs Sales
Patterns to watch:
High impressions + low CTR → traffic relevance issue
Good CTR + low conversion → listing problem
This helps validate what Business Reports already show.
📈 Real-World Examples
Example 1: Beginner Private Label Seller
Seller Type: New FBA seller

Example 2: Established Brand with a Sales Drop
Seller Type: 7-figure brand
Problem: Sudden 30% sales decline
Diagnosis:
Sessions dropped sharply
USP remained stable
Action Taken:
Identified lost keyword indexing after title update
Restored core keywords

⚠️ Common Mistakes to Avoid
Increasing ad spend before fixing conversion
Why it happens: Sellers assume “more traffic = more sales”
Do this instead: Fix USP first, then scale traffic
Judging performance by sales alone
Why it happens: Sales are the most visible metric
Do this instead: Always start with Sessions and USP
Making multiple changes at once
Why it happens: Sellers want fast results
Do this instead: Change one variable, wait 7–14 days, then evaluate
✅ Expected Results
After applying this framework, sellers typically see:
Clear identification of traffic vs conversion bottlenecks
More efficient ad spend
Higher listing conversion rates
Faster, more predictable scaling decisions
Fewer reactive or guess-based optimizations
❓ FAQs
How often should I check traffic vs conversion?
Weekly for active ASINs, daily during launches or promotions.
What matters more: traffic or conversion?
Conversion comes first. Traffic only helps if the listing converts.
Can seasonality affect this diagnosis?
Yes. Always compare to similar historical periods.
Is low conversion always a listing problem?
Not always. Pricing, reviews, and fulfillment issues can also reduce conversion.
Should I pause ads if conversion is low?
Not always. Reduce spend, but keep enough data flowing to measure improvements.
