Nine causes, in the order they are worth checking. Most sellers start with the advertising, because that is the dashboard they look at every day. Advertising is usually the symptom, not the cause.
Written by people who run their own brands on Amazon, not only other people’s.
Pick the exact week the drop started. Not the month — the week. Then compare that week against the four before it, in Business Reports, by ASIN.
You are looking for which number moved first. Sessions, or conversion? If sessions fell and conversion held, fewer people arrived and the page is fine. If sessions held and conversion fell, the same people arrived and stopped buying. Those are two completely different problems, and half of the wrong fixes come from skipping this step.
Sessions down is a traffic problem. Conversion down is a page problem. Find out which one you have before you touch a bid.
Roughly ordered by how often they turn out to be the real answer.
The listing still looks fine. The sales go to whoever holds the box. This is the single most common cause and the easiest to miss, because nothing on the page looks broken.
Where to look: Business Reports → Detail Page Sales and Traffic by Child Item, Buy Box percentage column. Anything below 90% on your own brand needs an explanation.
Rank decays while you are out and does not come back on its own when you restock. A four-day gap in a competitive keyword can take six weeks to recover, and most of that recovery has to be bought back with advertising.
Where to look: Inventory → Manage FBA Inventory, and your own shipment history. Line the out-of-stock dates up against the week the sales fell.
A competitor buys your brand name, or places Sponsored Products on your detail page. Your organic position has not changed at all. The clicks are being taken before they reach you.
Where to look: Search your own brand name and your best products as a shopper, in an incognito window, on the marketplace in question. Then check Brand Analytics → Search Query Performance for your branded terms: if impressions held and your click share fell, you are being intercepted.
Another seller edited the title. Amazon merged or split a variation family. An image was swapped. A bullet was truncated. These happen quietly and nobody emails you about it.
Where to look: Your own screenshots, or the listing’s edit history. If you do not keep screenshots of your own detail pages, start this week — it is the cheapest insurance on Amazon.
Demand shifts. A new phrase takes over a category and the listing is still written for the old one. The drop looks gradual, which is why it gets blamed on the season.
Where to look: Brand Analytics → Search Query Performance. Compare this quarter against the same quarter last year, by query. The queries you have lost will be obvious.
Not the average — the top review. A critical review pinned at the top of the page moves conversion more than a tenth of a star does.
Where to look: Open the detail page as a shopper and read the first three reviews. Then check whether the rating crossed a round number, 4.3 to 4.2 or 4.0 to 3.9.
A budget cap hit mid-month. A bid rule moved. A campaign lost its best keyword to a negative added months ago. Spend can look identical while the mix underneath it has turned over completely.
Where to look: The search term report, this month against three months ago. Not the campaign totals — the terms. Totals hide this.
Sometimes it is not you. Worth establishing early, because it changes what you should do: hold margin rather than chase volume into a falling market.
Where to look: Product Opportunity Explorer, at category level, against the same period last year. If the category fell and you fell less, you gained share.
In Europe this is a real and growing cause. A missing EPR registration, a packaging registration, no responsible person, or an expired document. The listing goes quiet rather than disappearing loudly.
Where to look: Account Health, and the Compliance dashboard per marketplace. Germany and France enforce most aggressively.
Across the accounts we take over, the pattern is consistent enough to be worth stating plainly.
| If this moved | Look here first |
|---|---|
| Sessions fell, conversion held | Buy Box, stock gap, rank lost to a competitor, or advertising on your listing |
| Conversion fell, sessions held | The page itself: a changed image, a new top review, a price move, or a competitor who improved theirs |
| Both fell together | Stock, suppression or compliance. Something structural, not gradual |
| Only one marketplace fell | Local: compliance, a local competitor, or a translation that was never right |
The honest version: most drops we are called in for turn out to be a Buy Box or a stock gap from weeks earlier. The advertising was fine. It was just the only place anyone was looking.
