You match the bid.
You match the budget.
You expect the same results.
But instead — performance drops, impressions die, and the keyword completely resets.
Every Amazon advertiser has felt this pain.
And here’s the truth:
When you move a keyword, you don’t just move the keyword.
You delete the history that made it successful.
A high-performing keyword isn’t powered by bids or match types alone.
It’s powered by months of invisible algorithmic trust signals built inside that specific campaign.
When you duplicate or relocate it, the keyword starts from zero:
• No click history
• No conversion signals
• No placement data
• No relevancy score tied to the old campaign
• No auction behavior patterns
• No predictive performance history
This is why duplicated campaigns almost always struggle — and why sellers unknowingly kill their best keywords.
Most advertisers turn off the original campaign too fast, long before the new one builds enough history.
That’s when revenue drops and panic starts.
Here’s the honest truth:
If a keyword is performing inside a messy campaign, leave it there.
Messy structure doesn’t hurt you — broken signals do.
Some of the most profitable accounts I’ve seen look chaotic on paper…
but they contain one or two keywords producing massive returns simply because their historical trust is intact.
The campaign may look messy — but the signals are clean.
And clean signals are gold.
However, if you must isolate a keyword (for ranking, for budget control, or for scaling), follow this rule:
Run both campaigns at the same time
Let the new campaign build fresh history slowly
Only phase out the old one when the new one proves stability
