Why does my Amazon campaign have zero impressions?
A campaign with zero impressions is failing the auction, not broken: your bid is below the floor for those keywords, the daily budget already exhausted, the offer lost the Buy Box (ads won't serve), targeting is too narrow, or it's simply night hours in your marketplace. Check in that order. The fix is usually a modest bid raise on evidence — not doubling everything in a panic.
The reasons, most common first
Bid below the auction floor
Every keyword has an effective minimum. Bidding ₹3 where page-one costs ₹11 buys you nothing — literally. This is the most common cause on new campaigns.
Budget exhausted before you looked
A small daily budget can be spent by 10am; the rest of the day shows zero delivery and the campaign looks dead.
No Buy Box, no serve
Sponsored Products require the featured offer. If the Buy Box is lost, impressions collapse regardless of bids.
Targeting too narrow
Five exact-match keywords with low volume plus a restrictive negative list can leave the auction with nothing to enter.
It's 3am
Low overnight impressions are normal buyer behaviour, not a delivery problem. Raising bids at night because impressions "stopped" burns money at the worst hours — day hours tell the truth.
How to check it yourself
Diagnose in order:
-
1
Campaign Manager → check budget consumed for today (if 100%, that's the answer).
-
2
Compare your bid to Amazon's suggested bid range per keyword — below the low end usually means no delivery.
-
3
Confirm the Buy Box on the advertised products.
-
4
Count targetable keywords after negatives; under ~10 with low volume, widen before raising bids.
-
5
Only judge delivery on daytime hours in your marketplace timezone.
The panic-raise trap
Doubling every bid at midnight because impressions "died" doesn't buy impressions at 1am — buyers are asleep. It buys expensive clicks at 9am at the panic price. Bid changes should follow daytime evidence with small steps and a revert if nothing improves.
How AIAdKing handles this for you
AIAdKing's campaign accelerator watches new campaigns hourly, raises bids in small steps only during buying hours in your marketplace timezone (never reacting to quiet nights), holds a 2-hour gap between raises so Amazon can respond, reverts automatically if a raise buys impressions but no economics, and stops with an alert instead of raising forever when the listing itself is the blocker.
Sellers also ask
How long should a new campaign take to get impressions? +
With a competitive bid and healthy listing: hours. Give a new campaign a business day before intervening — but zero impressions after 24 hours with a sensible bid means one of the five causes above, not patience.
Should I use Amazon's suggested bid? +
The suggested range is a fair starting anchor for delivery, then adjust on your own conversion economics. Starting far below it usually means a week of nothing.
Do negative keywords block my own keywords? +
Yes — a careless negative (broad "chess" while targeting "chess set") silently kills your own targeting. Audit negatives whenever delivery seems impossible.
