Question

I have a subpage in a jquery mobile page where I’d like to insert att Google adwords conversion cookie. But using the traditional snippet from Adwords doesn’t work. On Android it even makes the page go blank.

Anyone done this before?

Answer 1

You are probably loading the conversion script later on the page by doing something like this:

(function(){
    var s=document.getElementsByTagName('script')[0];
    var ga=document.createElement('script');
    ga.type='text/javascript';
    ga.async=true;
    ga.src='http://www.googleadservices.com/pagead/conversion.js';
    s.parentNode.insertBefore(ga,s);
})();

Or using a jQuery function to load scripts that is similar to the function above. Turns out that you can’t include the conversion.js script in this manner because it uses document.write to write the img tag on the page. Because it uses document.write some browsers will remove everything from the page and replace the content with the output of document.write, which in this case is an empty gif.

You better use the default tag provided by google to mark a conversion. If you need to load it without a page refresh just open an iframe to a page that contains this tracking code.

<script type="text/javascript"> 
  var google_conversion_id = 1234567890;
  var google_conversion_language = "en_US";
  var google_conversion_format = "1";
  var google_conversion_color = "666666";
  var google_conversion_label = "Purchase";
  if (10.0) {
    var google_conversion_value = 10.0
  }
</script>
<script type="text/javascript" src="http://www.googleadservices.com/pagead/conversion.js">
</script>
<noscript>
  <img height=1 width=1 border=0 
  src="http://www.googleadservices.com/pagead/conversion/1234567890/?value=10.0&label=Purchase&script=0">
</noscript>

Of course this is just an example. You should use your own code that have your unique conversiod_id.
