Amazon Sales Dropped Suddenly? A Diagnosis in Six Checks

Key takeaways: A sudden sales drop is a sessions problem or a conversion problem, and the Business Reports tab tells you which within five minutes. Check listing status, Buy Box, stock, ad delivery, price position and rank in that order. Do not change bids or copy until you know which number moved.

Answer the first question before anything else

Open Business Reports, choose Detail Page Sales and Traffic by Child Item, and compare the last seven days with the seven before. Two columns matter: sessions and unit session percentage. If sessions fell and conversion held, you have lost traffic. If sessions held and conversion fell, something on or around the page changed. If both fell at once, the listing was probably unavailable for part of the period. This one split decides which of the six checks below you run first, and it stops the most common mistake, which is cutting bids on a listing that simply went out of stock.

The six checks in order

1. Is the listing live?

Go to Manage All Inventory and filter for suppressed, inactive and stranded. A listing can be suppressed for a missing main image, a restricted claim in the copy or a category attribute that changed. It can also be blocked at the ASIN level after a pricing error or a safety complaint. Check Account Health for policy notifications on the same day the drop started. If the listing was down for three days, the sales curve will show a hole rather than a slope, and nothing else needs fixing until it is back.

2. Did you lose the Buy Box?

In Business Reports, the Featured Offer percentage column shows how often your offer was the one in the cart button. If it dropped from the high nineties to something lower, another seller is on the listing, or your price rose above Amazon's reference for the product, or your shipping time slipped. Ads only run when you hold the Featured Offer, so a Buy Box loss also cuts paid traffic, which is why it can look like a traffic problem at first.

3. Are you in stock, and are ads delivering?

Check FBA inventory for the child ASINs that carry most of the sales. A stock-out on the best-selling size or color drops the parent's total even though the listing is live. Then open Campaign Manager and look at spend by day for the same window. Spend that fell to zero means an out-of-budget campaign, a payment failure on the advertising account, or an ad rejected in moderation. Spend that held while sales fell points back to the page.

4. Did the price position change?

Your price may not have moved, but the price around you may have. Look at the top three competitors on your main keyword and note their current price, coupon and deal badge. A competitor running a 20% coupon for two weeks can cut your conversion rate by a third without any change on your side.

5. Did the page change?

Amazon can alter a listing without your input: a contribution from another seller overwrites a title, a variation gets split, a review is removed and the rating falls below a threshold shoppers filter on, or an image is rejected. Compare the live page against your saved copy. Read the newest reviews too. A cluster of one-star reviews about the same defect will move conversion faster than any copy change can recover.

6. Did rank or demand move?

Only now look at keyword rank. Search Query Performance in Brand Analytics shows impressions and clicks per query by week. If your share of impressions fell on the top queries, rank slipped. If total query volume fell across the category, demand moved, which is seasonal or market-driven and is not fixed by spending more.

What not to do in week one

Do not raise bids across the account to buy the sales back. If the cause is conversion, more clicks at a lower conversion rate raise ACoS and do nothing for the trend. Do not rewrite the listing while a suppression or Buy Box issue is open, because you will not be able to read the effect of the rewrite. Fix the cause, give the account a week of clean data, and then judge whether anything else is needed.

How we run this

Every account we manage has one owner for this diagnosis, and the six checks run in the same order every time. The output is a single line in the weekly report: the cause, the fix, and the number we expect to recover first.
