Prerequisites for ROAS bidding
To use target ROAS bidding, most campaign types need at least 20 conversions in the past 45 days. The exception is Search campaigns, which need at least 15 conversions in the past 30 days. To maximize results and give machine learning algorithms enough data to make informed bidding decisions, we recommend that you have at least 50 conversions in the past 30 days.
Prerequisites for using Smart Goals
To use Smart Goals, you’ll need to meet certain prerequisites and complete the following actions:
- Link your Analytics and Google Ads account(s).
- The linked Google Ads account(s) must send enough traffic to your website; Google Ads clicks have to result in at least 500 Analytics sessions over the past 30 days before you can set up Smart Goals.

- The reporting view must not receive more than 10 million sessions in 30 days.
