Create a Legacy Conversion Pixel

Learn how to create and implement Legacy Conversion Pixels to effectively track user actions from your advertising campaigns. This guide outlines the differences between Universal and Legacy Pixels, and provides step-by-step instructions for setup and code export.

Standard Conversion Pixels are designed for specific tracking scenarios where you need detailed control over conversion attribution and tracking parameters. This guide covers the advanced features and configuration options available when creating Standard Pixels.

New to pixel tracking? Start with our main pixel creation guide to understand the basics of Universal Tag vs Standard Pixel options.


Understanding Standard Conversion Pixels

Standard Pixels offer granular control over conversion tracking with these key advantages:

  • Standalone Operation: Works independently without requiring a Universal Pixel installation
  • Advanced Attribution: Configurable post-view and post-click attribution windows
  • Flexible Conversion Counting: Choose between single or multiple conversions per user
  • Multiple Implementation Options: JavaScript, Image tag, or Server-side tracking
  • Server-Side Capabilities: Advanced server-to-server tracking for complex scenarios

When to Use Standard Pixels:

  • You need specific attribution window settings
  • Tracking mobile app conversions or complex user journeys
  • Server-side implementation is preferred or required
  • You want standalone pixel operation without Universal Pixel dependency

Standard Pixel Creation

Creating a Standard Conversion Pixel

Follow these steps to configure your Standard Pixel in the ad:personam dashboard:

1. Choose Standard Pixel Type

From the pixel creation dialog, select "Standard Pixel" to access advanced configuration options.

2. Configure Basic Settings

Pixel Name: Enter a descriptive name that clearly identifies the conversion action you're tracking (e.g., "Mobile App Install" or "Premium Subscription Purchase").

3. Set Repeat Conversion Rules

Choose how to handle multiple conversions from the same user:

  • Count one conversion per user: Best for one-time actions like signups or first purchases
  • Allow multiple conversions: Ideal for recurring actions like repeat purchases or content downloads

4. Configure Attribution Windows

Set precise timeframes for conversion attribution:

Post-View Attribution Window (1-30 days): How long after seeing your ad should conversions be attributed to the view.

Post-Click Attribution Window (1-30 days): How long after clicking your ad should conversions be attributed to the click.

Pro Tip: Longer attribution windows capture more conversions but may include less relevant actions. Consider your typical customer journey length when setting these values.

5. Generate Pixel Code

Once configured, click "Create Pixel" to generate your tracking code. You'll receive three implementation options:


Implementation Options

JavaScript Tag Implementation

Place this script on your conversion page:

<!-- Conversion Pixel - [Pixel Name] - DO NOT MODIFY -->
<script src="https://secure.adnxs.com/px?id=[PIXEL_ID]&t=1" type="text/javascript"></script>
<!-- End of Conversion Pixel -->

Best for: Most web-based conversion tracking scenarios.

Image Tag Implementation

Use this HTML image tag for simple tracking:

<!-- Conversion Pixel - [Pixel Name] - DO NOT MODIFY -->
<img src="https://secure.adnxs.com/px?id=[PIXEL_ID]&t=2" width="1" height="1" />
<!-- End of Conversion Pixel -->

Best for: Environments where JavaScript isn't allowed or email tracking.

Server-Side Implementation

For advanced server-to-server tracking scenarios:

http://sspx-router.adnxs.net/sspx?id=[PIXEL_ID]&sspdata=[SSPDATA]

Best for: Mobile app tracking, complex attribution scenarios, or environments requiring server-side calls.

Managing Your Standard Pixels

After creation, monitor and manage your Standard Pixels through the Pixels dashboard:

  • Track Performance: View conversion counts and last-fired timestamps
  • Monitor Status: Ensure pixels are actively firing ("Active" status)
  • Update Settings: Modify attribution windows or conversion counting rules as needed
  • Access Code: Re-export pixel code for new implementations

Advanced Features

Custom Parameters

Add custom parameters to track additional conversion data:

?id=[PIXEL_ID]&order_id=1234&value=99.99&currency=USD

Multiple Tracking Methods

Combine different implementation methods for comprehensive tracking:

  • Use JavaScript tags for web conversions
  • Implement server-side calls for mobile app events
  • Add image tags as backup tracking

Testing Your Implementation

  1. Test Environment: Set up the pixel in a test environment first
  2. Verify Firing: Check the Pixels dashboard for successful test conversions
  3. Monitor Attribution: Ensure conversions are properly attributed within your set windows
  4. Validate Data: Confirm custom parameters are correctly passed and recorded

This advanced pixel configuration ensures accurate conversion tracking tailored to your specific campaign requirements and technical environment.
