Camapign Impressions gradually dropped to zero over a period of 4-5 days - PPC
Hi,
I am running different PPC campaigns for my ASIN and one of my campaigns, which targets only one keyword has stopped receiving impressions. Find a graph attached illustrating this.
All of the other campaigns are running fine but the broad and exact match campaigns for this keyword seem to have died.
I can confirm that the ASIN in question is indexed and organically ranked for this keyword and also making organic sales.
As far as I recall I tweaked two things:
- Started pausing campaigns during low sales hours: As far as I know this shouldn't be impacting the campaign. No other campaigns have been affected by this action.
- Updated my backend (generic keywords): I would assume that this could causes issues with indexing and this be causing troubles but as mentioned above indexing is retained.
Any ideas?
Contacted support but they've asked to me to wait for 3 consecutive days with zero impressions before they can escalate the issue. One day the campaign received 1 impression and the won't consider that as a day with no impressions.

Hi,
Here are a few points I’d check to help troubleshoot the drop in impressions. Some may be easy to rule out, but I’ll mention them for completeness:
- Account Issues (PPC Payment Errors): Unlikely, since your other campaigns are running fine, but worth a quick check.
- Product Issues (e.g., Buy Box): Since you’re still getting organic sales, it doesn’t appear to be a Buy Box issue.
- Budget Rules: Confirm there are no budget rules limiting this specific campaign’s ability to spend.
- Suggested Bids: This would be my top recommendation given the information provided. A competitor may have increased their bid on this keyword, potentially leading to a drop in impressions if they’re now outbidding you.
On the strategy of pausing campaigns based on sales volume: Low sales volume during certain hours of the day doesn’t necessarily mean ACoS is worse at those times. For instance, between 4 and 6 a.m., customers are often in a rush to get ready for work and may have less time to shop around. This can lead to higher conversion rates and, as a result, a particularly good ACoS. If you’re interested in exploring patterns like these in more detail, the Amazon Marketing Stream might be a helpful tool.
Hope this helps with your troubleshooting!

Hi again guys,
So yes I found the reason for this drop in impressions.
I found that a close variant (plural form) of my keyword was wasting my ad spent so I had added it as a negative exact match for that campaign.
What I didn't know was that it would also negate the actual keyword and hence all impression for that keyword were blocked.
While plurals make some sense I am noat very happy with how I can not negate variants like pepper for grinder if the target is pepper grinder.
How do you guys negate plurals and close variants for exact match campaigns?
