Most Amazon sellers check their sales numbers daily, but never inspect their listing's underlying health. By the time sales drop, the damage has been building for weeks.
A healthy listing maintains or grows organic rank, converts visitors at a competitive rate, and stays eligible for Buy Box. Here's the 7-point weekly checklist we use to monitor 50+ ASINs.
1. Conversion Rate Check
Your conversion rate (CR) is the single most important health metric. Log into Seller Central and check your CR for the past 7 days.
Healthy: CR within 10% of the category average (typically 5-15%).
Warning: CR dropped 20%+ week-over-week. Likely causes: new negative review, competitor price drop, or Amazon changed buy box eligibility.
Critical: CR below 3%. Something fundamental is wrong — check your Buy Box percentage, recent reviews, and pricing.
2. Keyword Ranking Position
Check your top 5-10 target keywords. Use the keyword tracking in Listing Grader or search manually in incognito mode.
A drop of 3+ positions on a primary keyword in one week indicates: a competitor optimized their listing, your sales velocity dropped, or the keyword's search volume shifted seasonally.
Action: If rank drops, increase PPC bid on that keyword by 15% and check if your listing content still targets that term effectively.
3. Inventory Status
Check your FBA inventory dashboard for:
- Sellable units: Do you have 30+ days of cover? If under 20, create a shipment immediately.
- Inbound status: Is your shipment on track? Delayed inventory is the most common cause of lost ranking.
- Stranded inventory: Any listing issues causing FBA to stop selling? Fix immediately.
4. Review Velocity
Check how many reviews you received in the past 7 days and the average star rating.
Ideal: 3-7 reviews per week, average 4.3+ stars. This rate tells Amazon your product is popular.
Warning: A single 1-star review can drop CR by 15-25% on low-review-count listings. Respond professionally.
Critical: Zero reviews in 14+ days. Adjust your follow-up email sequence or request Vine reviews.
5. Pricing Position
Your price relative to competitors determines Buy Box share and conversion rate.
If a major competitor dropped price by 20%+, you have two options: (a) match to maintain Buy Box, or (b) differentiate with a bundle, coupon, or improved packaging.
Never engage in a race-to-the-bottom price war unless you have a significant COGS advantage.
6. Buy Box Percentage
If your Buy Box percentage dropped below 90%, check who is winning the remaining share. Common causes: your price is too high, you're out of stock, or a new seller is undercutting.
If an unauthorized reseller is winning Buy Box, file a MAP violation or Brand Registry complaint.
7. Ad Performance Summary
Check your overall ACOS and impressions for the week. A sudden drop in impressions usually means either budget exhaustion or reduced keyword ranking.
If ACOS jumped 10%+ while impressions stayed stable, the issue is likely conversion-related. If ACOS spiked with increased impressions, your bids may be too high relative to conversion rate.
