What Target ROAS should I set in Google Ads?

Start with your historical ROAS minus 10-20%. If historical is 4:1, set target at 3.2:1 to 3.6:1 initially.

Is Google Ads ROAS better than Facebook?

They serve different intents. Google captures active searchers (higher intent), Facebook creates demand. ROAS benchmarks differ by platform.

How does Target ROAS bidding work?

Google's AI automatically sets bids to achieve your target ROAS. It needs 15+ conversions in 30 days to work well.

Why is my actual ROAS lower than Target ROAS?

Google optimizes for the target but can't guarantee it. Market competition, seasonality, and campaign changes affect actual ROAS.
