One lever at a time

The engine enforces one non-negotiable discipline: never adjust bid and budget on the same campaign in the same cycle.

Why

Smart Bidding recalibrates after every material change. Change the bidding strategy and the budget together and you've moved two variables at once - if performance shifts, you can't tell which change caused it, and Google's algorithm is trying to learn against a moving target. One lever, then wait, then the other.

How it shows up

• When a bidding change is recommended, the budget recommendation is forced to Hold for that campaign - even if a budget case exists.

• After a change is applied, the other lever is also blocked for the same campaign during the cooldown window.

• The decision card always tells you which lever is live and which is waiting.

Example. A campaign crosses 30 conversions and gets a "switch to tCPA" recommendation, and it's also budget-constrained. This cycle: the strategy switch. Next cycle, after the learning period: the budget scale - now measured against the new strategy's stabilised performance.
