How API Tracking Boosted EPC and ROI for Adult Dating Campaigns

27 June, 2025 Guides and Tutorials

In a highly competitive vertical like adult dating, it’s no longer enough to simply drive traffic — you need to track deeply, optimize quickly, and automate smartly. This case highlights how switching to API integration via the Marksel platform helped increase EPC by over 10%, with measurable impact on ROI.

Background

Offer Source: Affmy (Direct)
Vertical: Adult Dating
Geo: United States
Traffic Source: Branded members area traffic (native placements inside dating products)
Tracking Solutions Used:
Binom / Keitaro (legacy tracking setup)
Marksel platform (with API tracking)

Test Structure
We launched two parallel campaigns to evaluate the impact of API integration:

Campaign 1 — Standard Funnel (No API)
Used typical landing pages to warm up users
Click-based tracking only
No backend data exchange
Conversions tracked passively through pixel/postback
Limited optimization opportunities

Campaign 2 — Marksel + API Integration
Integrated API tracking to establish real-time data exchange between traffic and offer platforms
Modified landing pages to include an email capture form
Used backend logic to push session data instantly
Enabled creative and landing page automation based on user interaction and source performance
Improved attribution accuracy and control over each touchpoint

Results Breakdown
Without API (Standard Funnel via Affmy Direct)
Visits: 3,260
EPC: $0.1678

With API (Integrated via Marksel)
User Sessions: 1,355
EPS (Earnings per Session): $0.185
CR (Conversion Rate): 83.0%
ROI: 1.28

Why API Makes a Difference
API integration isn’t just about cleaner data — it unlocks a new level of control and flexibility, especially in dynamic verticals like adult dating.

Here’s what we achieved thanks to API tracking on Marksel:
Higher EPC (+10%) through better targeting and session tracking
Landing Page Personalization: We could test and switch landings in real time, depending on traffic quality
Creative Optimization: Creatives were adapted dynamically based on user agent data and click patterns
Traffic Routing Logic: API allowed for redirect adjustments mid-session without losing attribution
Reduced Discrepancy: Server-to-server data exchange eliminated gaps between platforms like Affise, Binom, and advertiser’s endpoint
Faster Iteration: We could implement micro-changes (copy, flow, prelanders) and see results in real time

Lessons Learned
Working with click-only funnels is no longer viable if you want to scale profitably. Discrepancies, broken attribution, and delayed data make optimization nearly impossible.

API tracking:

Provides reliable and rich performance data
Enables automated funnel control and testing
Drives higher CR, EPC, and ROI
Reduces tech debt and manual ops across tracking systems

Conclusion
For affiliate teams, media buying agencies, or networks operating in the adult vertical, Marksel with API tracking and Cascades management is a game-changer.

It’s not just about tracking.
It’s about building smarter funnels that adapt, learn, and scale — automatically.
