Google has updated its Demand Gen bidding documentation, lowering the recommended daily budget for campaigns using Target CPA bidding.
The new guideline suggests a budget of at least 10 times the target CPA, down from the previous recommendation of 15 times. This change makes it easier for advertisers to engage with Demand Gen campaigns that utilize tCPA bidding strategies, potentially encouraging more brands to test their efficacy.

This update could assist advertisers who previously hesitated to start due to higher financial commitments under the old 15x rule.
