ClickTag for Google Ad Manager

GAM requires a specific pattern to detect clickTags. The clickTag variable must be declared as a global variable in the <head>:

<script type="text/javascript">
var clickTag = "https://www.example.com";
</script>

GAM overrides the default URL with the click-through URL from the creative settings. The click handler uses window.open(window.clickTag).

Common Mistakes

  • var clickTag inside <body> — GAM scans <head> only
  • Dynamic URI param parsing — GAM doesn't recognize getUriParams.clicktag
  • clickTag in a closure/IIFE — Must be a global variable
  • Minified clickTag code — GAM can't parse minified declarations
  • Missing ad.size meta — GAM needs this for dimensions
