A PPC budget is not a spending limit
It is a bet on which keywords deserve your money
Treat it like a fixed bill
You will starve your winners
while your losers keep eating
Start with your break even ACoS
Take your profit margin before ad spend
That is the ceiling for any single campaign
Spend above it and every sale costs you money
Know this number before you touch a single bid
Watch TACoS
not just ACoS
ACoS only grades your ads
TACoS shows whether ad spend
is lifting total sales
including organic
During a launch
High TACoS is fine if organic rank is climbing
If TACoS stays high and organic sales stay flat
Your ads are renting sales
instead of building rank
Give data time before you judge it
Amazon attribution lags by a few days
Cut a campaign too early
You kill it right before the sales report catches up
Check when campaigns run out of budget
not just whether they do
A campaign that dies at lunch
misses every evening shopper
That is often your best converting traffic
With Cyber Five here
Set up budget rules in Campaign Manager now
Schedule based rules raise budgets for the event dates
Performance based rules raise them only when ROAS holds
Both stop you from going dark
during the busiest days of the year
Budgets that win are reviewed every week
and moved on purpose
Money follows performance
Never the other way around
