Overview

With the Conversion Pixel from AdUp Technology, you measure conversions and assign them to your campaigns. This allows you to identify which advertisements, keywords, or placements are achieving the best results.

Typical conversions include:

  • Purchases

  • Registrations

  • Contact enquiries

  • Newsletter signups

  • Page impressions of specific landing pages

A prerequisite for tracking is at least one active campaign in your advertiser account.


How Conversion Tracking works

For each desired conversion, you create an individual conversion code in the advertiser frontend.

You then integrate this code on the page where the conversion is completed — for example, on the:

  • order confirmation page

  • thank-you page

  • registration confirmation

  • successful form submission

Tracking is carried out via an embedded <img> tag.

As soon as a user reaches your website via an AdUp ad, temporary tracking information is stored. If the conversion pixel is subsequently loaded, the conversion can be assigned to the corresponding campaign.


Creating Conversion Code

Step 1: Log in

Log in to the advertiser frontend with your access details.


Step 2: Open Conversion Tracking

Navigate to:

Tools → Conversion Tracking


Step 3: Create new conversion code

Click on:

Create conversion code


Step 4: Configure conversion

Assign:

  • a unique name

  • a conversion type

Available types:

  • Enquiry

  • Registration

  • Page view

  • Sale

  • Other

This classification is used exclusively for internal organisation.


Step 5: Define conversion value (optional)

Optionally, you can store a fixed conversion value.

Alternatively, you can pass the value to the pixel dynamically at a later stage via URL parameters.

Example:

&total=199.99


Step 6: Set counting method (optional)

You can define an individual counting method for each conversion code.

Count every conversion

Every valid conversion after an ad click is recorded.

Suitable for:

  • recurring purchases

  • multiple orders

  • repeated actions

Count unique conversions

Only the first conversion after a click is counted.

Suitable for:

  • registrations

  • lead generation

  • one-off conversions


Step 7: Save

After saving, the new conversion code will automatically appear in the overview.

There you will also find the complete integration code.



Integrating the Conversion Pixel on your website

Pixel Integration

Integrate the conversion pixel within the <body> section of the page where the conversion is completed.

Example:

..
<img src="https://d.adup-tech.com/campaign/conversion/[USER_ID]?[PARAMETER]"      
     width="1px"
     height="1px" 
     border="0px"
     alt="" />


..
<img src="https://d.adup-tech.com/campaign/conversion/[USER_ID]?[PARAMETER]"      
     width="1px"
     height="1px" 
     border="0px"
     alt="" />


..
<img src="https://d.adup-tech.com/campaign/conversion/[USER_ID]?[PARAMETER]"      
     width="1px"
     height="1px" 
     border="0px"
     alt="" />

You can find the unique integration code in the advertiser frontend under:

Tools → Conversion Tracking → Actions → Integration Code


Tracking multiple conversions

You can create as many conversion codes as you like.

This allows you to measure different conversion goals separately, for example:

  • Completed purchase

  • Newsletter subscription

  • Contact form

  • Demo request

Each conversion code can be integrated on a different target page.


Required parameters

Parameter: t

The t parameter contains your unique conversion code.

Requirements

  • maximum 255 characters

  • UTF-8 and URL-encoded

Example

t=ABCDEF


Optional parameters

Parameter: order_id

Unique order or transaction number.

Used for deduplicating conversions.

Requirements

  • maximum 25 characters

  • UTF-8 and URL-encoded

Example

order_id=A12345


Parameter: total

Passes the total value of the conversion.

Requirements

  • maximum of two decimal places

  • decimal separation with a dot

  • no thousands separators

  • maximum value: 99999.99

Example

total=399.98


Parameter: item_number

Optional item or product number.

Requirements

  • maximum 25 characters

  • UTF-8 and URL-encoded

Example

item_number=EF_7890


Best Practices

Only integrate pixel on conversion pages

The conversion pixel should only be loaded on pages where a conversion actually occurs.


Use dynamic values

Pass order values and order IDs dynamically in order to:

  • correctly evaluate revenues

  • prevent duplicate conversions

  • optimise campaigns more precisely


Test function after integration

Check after integration:

  • whether the pixel is loaded

  • whether the URL format is correct

  • whether all parameters are passed correctly


Common sources of error

Pixel is loaded on multiple pages

This can result in duplicate conversions.


Missing URL encoding

Parameters should always be transmitted URL-encoded.


Invalid value formats

Pay particular attention to the correct number format for the total parameter.

Correct:

399.98


Incorrect:

399,98
