It is possible with google ads to track conversions with a custom variable using the pixel only method to track conversions?
Our company uses this method We wish to add a custom variable to each tracked conversion. Unfortunately, we cannot find any information how to implement a custom variable with the pixel only approach.
Does anyone know what parameter to use to send a custom variable back to google using the pixel only approach? And does anyone know which parameters are allowed using the pixel only approach. I know parameter "label" is required and "guid" and "script" are available, but we do not know which other parameters can be used.
I assume it is just a simple as adding the right paramter to the script below. Something like:
<img src="http://www.googleadservices.com/pagead/conversion/123456789/
?label=AAA&guid=ON&script=0&CUSTOM_VARIABLE=1"/>
But as said, we cannot find any information on this subject. Hope someone can help!
