Smart Bidding with TrueView for Action includes two strategies: tCPA and Max conversions. Which is used for advertisers who are new to driving conversions on YouTube and simply want to maximize conversions?

• A. tCPA
• B. Max conversions
• C. Target CPA
• D. Target ROAS

Answer: (A)

Target CPA uses a specific cost-per-conversion target and lets Smart Bidding work to drive as many conversions as possible while staying near that target. For advertisers who are new to driving conversions on YouTube, this provides a clear goal and a safety net: you set a CPA you’re comfortable with, and the system optimizes bids to maximize conversions within that cost boundary. This reduces guesswork and helps you learn quickly how campaigns perform because you’re measuring success in conversions without blowing through spend. As you gather more data, the bidding adjusts to approach that target CPA while still seizing conversion opportunities, giving you both volume and cost discipline. In contrast, a pure maximize-conversions approach focuses on volume without a CPA cap, which can lead to unpredictable costs early on. So starting with a target CPA offers a practical balance of driving conversions and keeping costs under control for beginners.
