Glossary entry
What is ROAS (Return on Ad Spend)?
ROAS is revenue divided by ad spend, expressed as a ratio (3.0 ROAS means $3 revenue per $1 spent). It's the headline efficiency metric for ecommerce and any business where revenue is attributable to a single conversion event. Healthy targets are 2.0 to 4.0 depending on margin.
ROAS vs. ROI
ROAS counts gross revenue against ad spend. ROI counts profit (revenue minus all costs) against total investment. A 4.0 ROAS on a 50% margin product is a 2.0 ROI. Always know which one you're optimizing.
Target ROAS bidding
Google and Meta both offer Target ROAS bidding, where you tell the algorithm a revenue-per-dollar target and it bids accordingly. Needs accurate conversion value tracking and 50+ conversions per month per campaign to converge.
Why ROAS can mislead
ROAS is a ratio. A 10.0 ROAS on $1,000/month spend is mathematically excellent but commercially small. Always read ROAS alongside total profit dollars.
How Unled Network helps
Managed Campaigns sets ROAS targets per campaign, audits attribution monthly, and rebuilds the conversion stack when reported numbers diverge from finance reality.

Frequently asked
What's a good ROAS?
Depends on margin. 50% margin businesses can run on 2.0. 20% margin businesses need 5.0+.
Why is my ROAS dropping at scale?
Audience saturation. The most efficient slice of the audience converts first. Volume usually buys lower-value clicks.
Can I bid to ROAS without ecommerce tracking?
Lead-gen businesses can pass back assigned values per lead type. Anything else is guesswork.
How does iOS 14 affect ROAS?
Reported ROAS undercount on Meta because iOS opt-out hides conversions. Use a conversion API and modeled conversions to see truth.
