Targets are how Search Terms decides whether a term's spend is efficient. They're used only to judge recommendations - they never touch your Google Ads bidding.
Target CPA: your cost-per-sale goal in dollars. If it's $50, a term converting at $40 is strong; one at $120 is not.
Target ROAS: your return goal as a ratio. 4.0 means $4 back per $1 (400%).
Leave a field blank and Search Terms fills it in, in this order:
Google's live target for the campaign, if one is set.
Your campaign setting.
Your client setting.
The account average as a last resort.
For CPA, if nothing usable is found it falls back to a sensible derived figure. For ROAS there's no universal default, so when a usable ROAS target is missing, value-based changes simply stay in review rather than guessing.
How to set a target:
Open client (or campaign) settings.
Enter the target CPA and/or ROAS, or leave blank to auto-detect.
Save.
