💡 A Beginner’s Guide for Those Starting in Mobile VAS
Mobile VAS campaigns (Value Added Services — mobile subscriptions for content, games, utilities, and entertainment) are among the most profitable verticals in affiliate marketing.
But to earn consistently, you need to do more than just run traffic — you need to understand your numbers.
👉 In this guide, we’ll break down three essential metrics every affiliate must know:
- 💰 EPC (Earnings per Click) — how much you earn per click
- 🎯 CR (Conversion Rate) — how well your traffic converts
- 📈 ROI (Return on Investment) — how profitable your campaign really is
You’ll learn how to calculate, interpret, and improve each of them — step by step.
💰 EPC — Earnings per Click
EPC shows how much you earn on average from each click on your ad.
📊 Formula:EPC = Revenue / Number of Clicks
Example:
If your campaign generated $200 from 1,000 clicks, then EPC = $0.20.
🔍 Meaning:
- The higher the EPC, the more profitable your setup is.
- EPC helps you compare offers and traffic sources.
⚡️ Tip:
Don’t rely solely on the “average EPC” shown by the network — that’s the overall average across all affiliates.
Focus on your personal EPC. Test new creatives, pre-landers, and audiences to push your own EPC above the average.
🎯 CR — Conversion Rate
CR (Conversion Rate) shows what percentage of users complete the target action — for example, a subscription or purchase.
📊 Formula:CR = (Conversions / Clicks) × 100%
Example:
If 50 users out of 1,000 visitors subscribed → CR = 5%.
🔥 Interpretation:
- High CR = your offer and landing page are working well.
- Low CR = the traffic is poorly targeted or the page fails to persuade.
💡 Benchmarks:
- 2–3% → normal for e-commerce
- 5–10% → good for simple mobile subscriptions (mVAS)
- 10%+ → excellent for 1-click flows
📈 ROI — Return on Investment
ROI tells you how much profit your campaign generates compared to what you spent — the ultimate profitability metric.
📊 Formula:ROI = ((Revenue – Cost) / Cost) × 100%
Example:
You spent $100 and earned $200 → ROI = ((200 – 100) / 100) × 100% = 100%.
📊
- ROI > 0% → profit
- ROI = 0% → break-even
- ROI < 0% → loss
💡 Tip:
Always include all expenses — traffic, creatives, trackers, hosting, etc.
Only then will you see the real picture and make smart scaling decisions.
🧠 How to Improve EPC, CR and ROI
🔹 Traffic sources:
- Compare placements by EPC and CR.
- Cut “empty” traffic that brings clicks but no conversions.
- Keep your CPC lower than EPC — that’s how you stay profitable.
🔹 Creatives:
- Test different formats (banners, videos, native ads).
- Focus on user pain points or clear benefits.
- Don’t mislead — fewer clicks but higher CR is better than empty traffic.
🔹 Landing pages:
- Optimize for mobile 📱.
- Make the CTA button clear and visible.
- Remove unnecessary fields and steps — the simpler the flow, the higher CR.
- Run A/B tests: titles, texts, colors, button placement — and keep what converts best.
🔹 Offers:
- Check the payout and the subscription type (1-click, PIN-submit, MO/MT).
- Choose offers that truly fit your traffic.
- Don’t chase the biggest payout — focus on ROI instead.
⚙️ Metric synergy:
EPC and CR directly influence ROI.
When CR grows and CPC stays stable, ROI rises.
If EPC drops — the problem is usually the creative, landing, or traffic quality.
🔚 Conclusion
Analytics is the ❤️ of affiliate marketing.
Track these three core metrics:
- EPC — how much you earn per click
- CR — how well your traffic converts
- ROI — how profitable it all is
By combining analysis and testing, you turn chaotic traffic into predictable profit 🚀
Work with your numbers — and your mVAS campaigns will deliver stable, long-term results.
