Amazon Listing Health Score: What to Check Weekly

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.
