Target ROAS
Smart Bidding strategy that optimizes bids to hit a specific revenue-to-spend ratio.
Definition
Target ROAS (Return on Ad Spend) is a Smart Bidding strategy where you set a target revenue ratio (e.g., 400% = $4 revenue for every $1 spent), and Google automatically adjusts bids to achieve that return across your campaigns. Unlike Target CPA (which optimizes for conversion volume), Target ROAS optimizes for conversion value — making it ideal for healthcare practices that can track actual procedure revenue per patient.
The Practitioner's Perspective
Target ROAS requires assigning conversion values to your tracked actions. For healthcare, this means either using static values (a rhinoplasty consultation is assigned $5,000 expected revenue) or dynamic values (your CRM sends actual booking amounts back to Google through the API). Static values are simpler to implement; dynamic values are more accurate and result in better algorithm optimization.
The minimum data requirement for Target ROAS is more demanding than for Target CPA — Google recommends 15–20 conversions per month with conversion values. For many healthcare practices, this means Target ROAS is a later-stage optimization. Start with Target CPA once you have consistent conversion data, then transition to Target ROAS when you can reliably attribute revenue to individual ad-driven conversions.
Target ROAS is particularly powerful for practices with a mix of high-value and lower-value procedures in the same account. The algorithm bids more aggressively for queries likely to lead to rhinoplasty ($8,000 procedure) and less aggressively for queries likely to lead to a single Botox appointment ($400 procedure) — optimizing total revenue, not just conversion volume. This value-based optimization is impossible to replicate with Target CPA alone.
Frequently Asked Questions
What Target ROAS percentage should I set?
Start at a level your historical data supports. If your current ROAS is 350%, set a target of 300–320% (slightly below to allow room for the algorithm to perform). Once it's consistently hitting that target, increase gradually. Setting an unrealistically high ROAS target will cause the algorithm to sacrifice volume.
How do I assign conversion values for healthcare?
For simplicity, use average procedure values as static conversion values (e.g., consultation = $3,500 average procedure value). For accuracy, integrate your booking/CRM system with the Google Ads Conversion API to pass actual appointment revenue dynamically. The latter requires developer work but produces much better optimization.
Can I use Target ROAS if I only track form fills, not revenue?
Technically yes, by assigning a static dollar value to your conversion action. But it's only meaningful if that value reflects real patient revenue. If you assign $100 to a form fill but some form fills become $10,000 procedures and others never convert, the algorithm is optimizing for a proxy that may not reflect actual business outcome.
