Return on Ad Spend (ROAS)
Revenue generated for every dollar spent on ads.
Definition
Return on Ad Spend (ROAS) is the ratio of revenue attributed to your Google Ads campaigns divided by the total spend. A 5x ROAS means you generated $5 in revenue for every $1 spent on ads. For healthcare practices, ROAS is most meaningful when you can track procedure revenue back to specific campaigns — which requires robust conversion tracking and a CRM.
The Practitioner's Perspective
ROAS is the gold standard for e-commerce but requires more setup for service businesses like healthcare practices. To measure ROAS accurately, you need to know not just how many leads came from ads, but how many of those leads converted to booked procedures and at what value. This typically requires tracking from ad click → lead → consultation → booked procedure using a CRM integration.
For practices that can measure it, ROAS targets vary by procedure type and margin. A plastic surgery practice might target 3–5x ROAS, while a med spa with lower ticket sizes might target 4–8x. The Target ROAS bidding strategy in Google Ads allows you to set these targets and let Google's machine learning optimize bids to hit them — but it requires at least 15–20 conversions per month to work effectively.
One common mistake in healthcare is conflating 'lead ROAS' (revenue from all leads, not just ones that closed) with true ROAS. If you're measuring revenue at the lead stage rather than the closed-patient stage, you're overstating performance. Track closed revenue from ads to get the real number.
Frequently Asked Questions
What ROAS should a medical practice target?
A 3–5x ROAS is a healthy target for most practices. This means for every $1,000 in ad spend, you generate $3,000–$5,000 in procedure revenue. Higher-ticket practices (plastic surgery, bariatric) can often achieve 5–10x ROAS with well-optimized campaigns.
How is ROAS different from ROI?
ROAS measures gross revenue against ad spend only. ROI factors in all costs (ad spend, management fees, overhead) and measures net profit. A 4x ROAS may still be unprofitable if your margins are thin. ROAS is a campaign efficiency metric; ROI is a business profitability metric.
Can I use Target ROAS bidding with a small budget?
Target ROAS requires sufficient conversion data — Google recommends at least 15 conversions in the past 30 days. If you're below that volume, start with Target CPA or Maximize Conversions, then switch to Target ROAS once you have enough data.
