Changing auto campaign - impressions fall of cliff


We’ve been selling on Amazon a few weeks and the auto campaign has been doing well. I tried to be clever and took out the best performing searches (through negative keywords) to put into a manual campaign. That day our sales dropped a lot, I panicked, paused the new manual campaign and removed the negative keywords from the auto campaign.
Now our impressions have plummeted and our best performing asins haven’t featured in the auto campaign.
I have 3 questions:
How long should it take for my new manual campaign to start working - I was expecting straightaway?
Has my tampering with the auto campaign caused the algorithm to re-set?
If so, should I redo what I did originally and let the manual campaign do it’s thing with all our best performing asins?

Any advice or insights from more seasoned sellers would be very much appreciated. Christmas is coming and I’m a bit worried about this turn of events.

It’s not uncommon to experience fluctuations in performance when making changes to your advertising campaigns. Here are some insights to consider:

  1. New Manual Campaign: A new manual campaign may take some time to gain traction and start performing effectively. Give it a few days to a week for Amazon’s algorithm to optimize and deliver results. Patience is essential in the early stages of a campaign.
  2. Impact of Changes: Making significant changes to your auto campaign, such as removing best-performing searches through negative keywords, could have disrupted the algorithm’s optimization. The sudden drop in impressions might be a result of these changes.
  3. Algorithm Reset: Amazon’s algorithm might need some time to readjust after the changes made to your auto campaign. When you pause or modify a campaign, it can temporarily affect the algorithm’s learning and performance.
  4. Restoring Original Settings: If your best-performing ASINs were featured in the auto campaign, consider reverting the changes you made and letting the auto campaign run with its original settings. This can help the algorithm regain stability and potentially bring back the performance you experienced before.
  5. Monitor Performance: Continuously monitor the performance of both the auto and manual campaigns. If you see improvements or stabilization in the auto campaign, you can decide to reintroduce the manual campaign and observe its impact.
  6. Stay Flexible: Advertising on Amazon can be dynamic, and it’s essential to be adaptable. Be prepared to adjust your strategies based on performance data and make data-driven decisions to optimize your campaigns effectively.

Lastly, remember that seasonal fluctuations and changes in ad performance are common.
