Your Amazon sales just crashed and you're staring at your dashboard like it betrayed you. Been there.
Last month, we helped 847 sellers figure out why their revenue tanked overnight. Here's the thing—sales drops aren't mysterious. They follow patterns, and every Amazon seller running into this problem needs a systematic way to diagnose it.
After analyzing thousands of seller accounts, we built an Amazon Sellers Diagnostic Checklist—seven critical checkpoints that reveal exactly what killed your rankings, tanked your conversions, or hijacked your Buy Box.
No guessing. No panic buying expensive courses. Just a step-by-step diagnostic framework that spots the real problem in under 30 minutes.
The 7-Point Amazon Sellers Diagnostic Checklist
Run through these seven checks in sequence to identify your problem within 30 minutes.
| Check | Problem | Quick Action |
|---|---|---|
| 1. Listing Hijacking | Unauthorized changes to title, bullets, images, or Buy Box | Use Helium 10 Alerts to monitor 24/7 |
| 2. Keyword Indexing | Lost indexing for critical keywords | Run Index Checker on top 20 converting keywords |
| 3. Ranking Plummet | Dropped from page 1 to page 5+ | Track 60-day ranking history with Keyword Tracker |
| 4. New Competitor | Well-funded competitor entered market | Monitor with Market Tracker for new ASINs |
| 5. PPC Underperforming | High ACOS burning budget without sales velocity | Review ACOS, CTR, conversion rates in Ads dashboard |
| 6. Negative Review Impact | Bad review tanking conversion rate | Use Seller Assistant to monitor sentiment trends |
| 7. Profit Erosion | Margins compressed by fees or COGS increases | Analyze true profitability in Profits dashboard |
Check 1: Has Your Listing Been Hijacked or Changed? (Use Alerts)
The Problem: Listing hijackers and unauthorized changes can kill your sales faster than a bad review bomb. Sometimes Amazon's algorithm changes your bullet points, titles, or even your main image without warning. Other times, competitors or hijackers manipulate your listing details to confuse customers or redirect traffic.
The Diagnostic Tool: Helium 10's Alerts function monitors your listings 24/7 for any unauthorized changes. It tracks everything from title modifications to bullet point edits, price changes, and even Buy Box hijacking attempts.

How to Run This Check:
- Log into your Helium 10 dashboard and navigate to Alerts
- Add your top-performing ASINs to the monitoring list
- Set up notifications for title changes, bullet point modifications, and Buy Box alerts
- Review the alerts history for the past 30 days
- Check if any changes coincide with your sales drop timeline
What to Look For:
Check 2: Are You Still Indexed for Your Main Keywords? (Use Index Checker)
The Problem: Amazon's indexing system can be temperamental. Your product might lose indexing for crucial keywords due to algorithm updates, policy violations, or technical glitches. Without proper indexing, your listings become invisible to customers searching for those terms.
The Diagnostic Tool: Helium 10's Index Checker instantly tells you which keywords Amazon is currently indexing your product for.
How to Run This Check:
- Open Index Checker in your Helium 10 toolkit
- Enter your main ASIN
- Input your top 20 converting keywords (check these in your Search Term Reports)
- Run the indexing scan
- Compare current results with a previous scan if available
| Keyword Status | What It Means | Action Required |
|---|---|---|
| ✅ Indexed | Amazon shows your product for this keyword | Continue monitoring |
| ❌ Not Indexed | Your product won't appear for this search | Immediate optimization needed |
| ⚠️ Partially Indexed | Limited visibility for this term | Review keyword placement |
Check 3: Did Your Keyword Rankings Plummet? (Use Keyword Tracker)
The Problem: Ranking drops often precede sales crashes by 1-2 weeks. Your product might have fallen from page 1 to page 5 for your money keywords, drastically reducing organic visibility and sales velocity.
The Diagnostic Tool: Helium 10's Keyword Tracker provides historical ranking data showing exactly when and how far your rankings dropped.
How to Run This Check:
- Access Keyword Tracker in your Helium 10 dashboard
- Review ranking history for your tracked keywords over the past 60 days
- Identify any sudden ranking drops that correlate with your sales decline
- Check ranking velocity trends for early warning signs
- Compare your rankings against direct competitors
What Ranking Patterns Mean:
Check 4: Did a New Competitor Enter the Market? (Use Market Tracker)
The Problem: New competitors—especially well-funded ones—can disrupt your market share overnight. They might launch with aggressive pricing, superior PPC budgets, or better product features that make your offering less attractive.
The Diagnostic Tool: Helium 10's Market Tracker monitors your niche for new entrants and tracks competitor performance metrics.
How to Run This Check:
- Open Market Tracker and review your main keywords
- Look for new ASINs that appeared in the past 30-60 days
- Analyze these new competitors' review counts, pricing strategies, and BSR performance
- Check if any new entrants have captured significant market share
- Review their listing optimization and PPC strategies

Check 5: Is Your PPC Campaign Underperforming? (Review in Helium 10 Ads)
The Problem: PPC performance directly impacts organic rankings through sales velocity signals. If your ad campaigns are burning budget without generating profitable sales, you're likely experiencing a double hit: wasted ad spend plus declining organic visibility.
The Diagnostic Tool: Helium 10 Ads provides advanced PPC analytics beyond what Amazon's native dashboard offers.
How to Run This Check:
- Access Helium 10 Ads and connect your advertising account
- Review campaign performance for the past 30 days
- Check key metrics: ACOS, conversion rates, click-through rates, and keyword performance
- Compare current performance against your historical averages
- Analyze search term reports for irrelevant traffic
Critical PPC Metrics to Monitor:
| Metric | Healthy Range | Warning Signs |
|---|---|---|
| ACOS | 15-30% (depending on margins) | >40% consistently |
| CTR | 0.5-2% | <0.3% or >3% |
| Conversion Rate | 10-20% | <8% for main keywords |
| CPC Trends | Stable or gradual increase | Sudden 50%+ spikes |
PPC Optimization Steps:
Check 6: Did You Receive a Negative Review? (Monitor with Seller Assistant)
The Problem: A single detailed negative review can tank your conversion rate, especially if it highlights a genuine product flaw or shipping issue. Amazon's algorithm also factors review velocity and sentiment into ranking decisions.
The Diagnostic Tool: Helium 10's Seller Assistant Chrome extension provides quick review monitoring and competitor analysis directly on Amazon product pages.
How to Run This Check:
- Install Seller Assistant Chrome extension
- Visit your product listing and scroll to the reviews section
- Check for new negative reviews in the past 30 days
- Analyze review sentiment trends and common complaint themes
- Compare your review metrics against direct competitors
Review Impact Assessment:
- 1-star reviews with photos: Highest negative impact on conversions
- Recent review clusters: Multiple reviews mentioning the same issue
- Verified purchase reviews: Carry more weight than unverified ones
- Review velocity drop: Fewer reviews per week can signal declining sales
Review Management Strategy:
- Immediate response: Reply professionally to legitimate negative reviews
- Product improvement: Address valid complaints in future inventory
- Follow-up campaigns: Increase positive review acquisition efforts
- Vine program: Consider Amazon Vine for established products (if eligible)
Check 7: Is Your Profit Margin Still Healthy? (Analyze in Profits)
The Problem: Sometimes sales appear to drop when actually your profit margins have eroded due to increased costs, fee changes, or pricing pressures. You might be selling the same units but making significantly less money per sale.
The Diagnostic Tool: Helium 10's Profits dashboard tracks your true profitability including all Amazon fees, PPC costs, and COGS changes.
How to Run This Check:
- Open Profits and review your product profitability over the past 90 days
- Check for margin compression trends even if unit sales remain stable
- Analyze fee changes, including FBA storage fees and referral fee updates
- Review your landed costs for any COGS increases
- Calculate your true ROI including PPC spend
Profitability Warning Signs:
Profit Recovery Tactics:
| Issue | Solution | Timeline |
|---|---|---|
| Rising COGS | Negotiate with suppliers or find alternatives | 30-60 days |
| High PPC costs | Optimize campaigns and focus on organic growth | 2-4 weeks |
| Amazon fee increases | Adjust pricing or improve operational efficiency | Immediate |
| Currency fluctuations | Hedge or adjust pricing quarterly | Ongoing |
