Here’s the method:
When a search term starts converting consistently (2–3 sales minimum), don’t just increase its bid…
Move it into a dedicated Exact Campaign for that single term.
Link it to the best-performing SKU only.
Add it as a negative in the original auto/phrase campaign.
Why this works:
-
Eliminates internal keyword competition.
-
Gives full budget control to proven queries.
-
Improves TACoS by isolating “profit keywords”.
-
Prevents algorithm dilution across multiple ASINs.
-
Makes scaling predictable instead of random.
Result: You stop “chasing keywords” and start building keyword-controlled profit engines.
