Which bidding option corresponds to aiming for installs at a target cost-per-install (tCPI)?

• A. Cost per click (CPC)
• B. Return on ad spend (ROAS)
• C. Target cost-per-action (tCPA)
• D. Target cost-per-install (tCPI)

Answer: (D)

Choosing a bidding strategy that targets a specific cost per install. This option is built to optimize for app installs while keeping each install's cost close to your defined target. Google Ads uses historical data and real-time signals to adjust bids so you get as many installs as possible within your budget, but at or near the set cost per install.

Other bidding options focus on different goals: cost per click aims to optimize for clicks rather than installs; ROAS targets revenue return rather than install cost; target cost-per-action optimizes for a chosen action, which can be any conversion, not exclusively installs. If your primary objective is to acquire users at a fixed cost per install, the target cost-per-install strategy is the most direct and appropriate choice.
