Stay on target ROAS and change conversion goal (campaign level optimisation)

At the campaign level, change to a new conversion goal or modify the composition of the existing conversion goal (add or remove actions as primary).

Recommended steps

Identify the new or existing conversion goal that you want to optimise towards.

1. a. If creating a new conversion goal, create a new conversion action and categorise it to the new conversion goal. Don't set your conversion goal as account default yet.
2. b. If you are changing the composition of an existing conversion goal (add or remove conversion actions), ensure the conversion category is the same as the existing goal. Don’t set the conversion action as primary yet.
3. c. Ensure that everything is configured and reporting values correctly before moving to step #2.

Based on your selection in #1 above, change to primary in select campaigns and enable campaign level settings.

1. a. Change to the new conversion goal (set at campaign level), or
2. b. Change composition of conversion goal (add or remove conversion actions as primary in select campaigns)

Keep bidding towards target ROAS.

1. a. Mitigate performance fluctuations by adjusting CPA targets.
2. b. Gradual target changes are recommended. However, if there is a significant difference in conversion rate and volume, consider larger target changes.

Repeat step #2 by moving campaigns in batches. Start with low conversion volume campaigns and scale up over time.

After moving over all campaigns, change the conversion action to the account default and slowly move from campaign-level bidding to account-level bidding.

Smart Bidding will adjust to the new target over the next 2–3 conversion cycles. Adjust ROAS targets and/or budgets to manage performance.
