Definition
Return on Ad Spend (ROAS) is revenue attributed to ads divided by ad spend. It answers “how much came back for each rupee we put into ads?” — not the same as total business ROI.
Detailed Explanation
ROAS looks simple until attribution gets messy. Last-click models undervalue content and Maps. View-through models can over-credit display. Agree whether revenue means paid orders, delivered COD, or booked consults before you compare campaigns.
Use ROAS next to CPA or cost-per-qualified-lead. A high ROAS on brand search can hide a weak non-brand funnel. A low early ROAS on a new product can still be fine if learning and creative tests are intentional. Finance should see the same definition marketing uses.
An education consultancy celebrating 8× ROAS on brand Search while non-brand CPL quietly rises is reading the wrong scoreboard. Split brand and non-brand before you call the account healthy.
Nepal Context
In Nepal, COD returns and WhatsApp closes often break neat ROAS dashboards. Agree what counts as revenue before you celebrate a number. Tracking setup: conversion tracking.
Write the ROAS definition in the campaign brief. If finance and marketing disagree later, the dashboard will not settle the argument.
Practical Examples
- E-commerce: NPR 100,000 ad spend → NPR 350,000 attributed revenue = 3.5x ROAS
- Lead gen: Use CPL/CPA until CRM revenue is tied back — do not fake ROAS
- Nepal COD: Track add-to-cart + confirmed orders from ops sheet weekly
Key Takeaways
- ROAS requires trustworthy revenue attribution.
- Seasonality changes acceptable ROAS bands.
- Blended ROAS across brand and non-brand misleads.
- Pair with margin, not only revenue.
Common Mistakes
- Reporting platform ROAS when half of sales close offline.
- Comparing ROAS across different product margins.
- Optimizing to ROAS while ignoring lead quality.
