Let’s begin!

1. What Is Digital Marketing ROI and Why It Matters

1.1 Definition & Formula

At its most fundamental level:

Net Profit from Marketing includes revenue directly attributable to marketing campaigns minus their associated costs. If you spend $100,000 and earn $300,000 in attributable revenue, net profit is $200,000 — yielding an ROI of 200%.

This measure communicates simply: for every rupee spent, what does the business earn back?

1.2 ROMI vs. ROI

Digital ROI is often referred to as ROMI (Return on Marketing Investment) — essentially the same concept but used interchangeably to emphasize marketing-specific attribution analyticodigital.com+1attanomedia.com+1vervocity.io+1wsj.com+1en.wikipedia.org.

2. Key Metrics to Measure ROI

You need more than just final revenue numbers. A variety of metrics give structure and transparency:

2.1 Cost per Acquisition (CPA) / Cost per Conversion

Measures how much you spend to acquire a single customer or lead:

Lower CPA = more efficient budgets ikonik.digitalsaleshive.com+4almondsolutions.com+4attanomedia.com+4.

2.2 Customer Acquisition Cost (CAC) & Lifetime Value (CLV)

CAC calculates acquisition cost across marketing, sales, and support. CLV measures the total revenue from a customer during the entire relationship analyticodigital.com+1ikonik.digital+1.

• CAC = Total acquisition spend / # new customers

• CLV = Avg revenue per sale × # of purchases × retention period en.wikipedia.org+9ikonik.digital+9almondsolutions.com+9

Comparing CLV with CAC reveals whether your marketing is sustainable long-term.

2.3 Return on Ad Spend (ROAS)

Focused on ad-focused ROI, this shows how much revenue you gain per advertising rupee:

A ROAS of 4:1 means ₹1 in ads yields ₹4 in revenue en.wikipedia.org+14ikonik.digital+14webfx.com+14.

2.4 Click‑Through Rate (CTR) & Conversion Rate

CTR indicates how well you attract clicks with your messaging:
CTR = Clicks / Impressions theaustralian.com.auen.wikipedia.org.

Conversion rate shows how many of those clicks actually convert:
Conversion Rate = Conversions / Visitors attanomedia.com+15analyticodigital.com+15webfx.com+15.

2.5 Cost Per Click (CPC), Cost per Lead (CPL), View-Through Rate (VTR)

• CPC: how much each click costs you — vital for PPC efficiency saleshive.com.

• CPL: cost to gain a qualified lead — especially important in B2B/premium industries vervocity.io+2webfx.com+2techfunnel.com+2.
