Case Study: How SDK Conversion Tracking Revealed Which Placements Actually Convert
Impressions and clicks are vanity metrics. What really matters is conversions - actual leads, sales, or signups that generate revenue. This case study shows how one buyer used PopTrades SDK to finally see which traffic sources were actually making them money.
The Problem
A media buyer was running popunder campaigns to a simple landing page with a signup form. They faced a common challenge:
- Blind optimization - They could see clicks and CTR but not which clicks converted
- Placement mystery - Some placements had great CTR but unknown conversion performance
- Wasted spend - Money going to sources that generated clicks but no real value
- Gut-feel decisions - Pausing or scaling placements based on assumptions, not data
Without conversion data flowing back to PopTrade, they were essentially optimizing for the wrong metric. A placement with 2% CTR and 0% conversion rate was treated the same as one with 1% CTR and 5% conversion rate.
What They Did
The buyer implemented PopTrades SDK conversion tracking on their landing page:
Step 1: Generated SDK Code
In the PopTrade dashboard, they used the SDK Generator to create tracking code:
- Selected their campaign
- Configured conversion parameters
- Generated the JavaScript snippet
Step 2: Installed Base Tracking
They added the PopTrade SDK script to their landing page header. This script:
- Captures the click ID from URL parameters
- Stores it for the user session
- Prepares for conversion event firing
Step 3: Added Conversion Event
On their thank-you page (shown after successful signup), they added the conversion call:
- Fires when the thank-you page loads
- Sends the conversion back to PopTrade with the original click ID
- Optionally includes conversion value for revenue tracking
Step 4: Verified Integration
Before scaling, they tested thoroughly:
- Completed test conversions from different placements
- Verified conversions appeared in PopTrade statistics
- Confirmed attribution was working correctly
Step 5: Analyzed and Optimized
With conversion data flowing, they could finally see:
- Conversion rate by placement
- Cost per conversion by source
- Which placements to scale vs pause
The Result
Conversion tracking transformed their campaign management:
- Data-driven decisions - Every optimization backed by real conversion data
- Hidden winners discovered - Some low-CTR placements had excellent conversion rates
- Budget vampires identified - High-CTR placements with zero conversions got paused
- Improved ROI - Budget shifted to placements that actually generated revenue
- Smart Rules automation - Set up rules to auto-pause placements below conversion thresholds
The buyer discovered that their assumptions about placement quality were often wrong. The data revealed a completely different picture than click metrics suggested.
Key Takeaways
CTR Lies, Conversions Dont
High CTR can indicate engaged users or it can indicate bot clicks, misleading placements, or accidental clicks. Only conversion data tells you whats actually valuable.
Integration Is Simpler Than You Think
Adding SDK tracking is typically just two code snippets - one on landing page, one on conversion page. Most developers can implement it in under an hour.
Test Before Scaling
Always verify conversions are tracking correctly with test transactions before making optimization decisions based on the data.
Enable Smart Rules Once Data Flows
With conversion data available, you can automate optimization - pause placements below target CPA, scale those exceeding targets.
When to Implement SDK Tracking
Conversion tracking is valuable if:
- You have a measurable conversion event (signup, purchase, lead form)
- Youre currently optimizing based on clicks or CTR alone
- You want to use Smart Rules based on conversion performance
- You need to calculate actual ROI per traffic source
- Youre scaling spend and need confident optimization data
Technical Implementation
Landing Page Code
Add the SDK script to capture incoming click parameters:
- Place in the head section of your landing page
- Loads asynchronously (wont slow your page)
- Automatically captures click_id from URL
Conversion Page Code
Fire the conversion event when user completes desired action:
- Call on thank-you page or after form submission
- Include optional revenue parameter for value tracking
- Can fire on any event (button click, page load, etc.)
Server-Side Option
For higher security or complex funnels, use server-side conversion API:
- Send conversions from your backend
- Harder for fraudsters to fake
- Works with multi-page conversion flows
Debugging Tips
- Check browser console for SDK errors
- Verify click_id parameter passes through your funnel
- Test with PopTrades conversion log viewer
- Allow a few minutes for conversions to appear in stats
You cant optimize what you cant measure. SDK conversion tracking gives you the visibility needed to make every advertising dollar count.
