Inserting Google Adwords Conversion Tracking with

Question

I'm pretty new to javascript, and therein probably lies my problem. I'm trying to track AdWords conversions that occur within a widget on our site. The user fills in a form and the result from the widget is published in the same div without a page refresh. The issue I'm having is when I try to appendChild (or append in jQuery) both script elements in Google's code (shown below) the page gets 302 redirected to a blank Google page (or at least that's what it looks like through FireBug). I'm able to provide a callback method for the results of the form, and that's where I'm trying to insert the AdWords tracking code. For reference, this is the code provided by Google:

<script type="text/javascript">
/* <![CDATA[ */
var google_conversion_id = 993834405;
var google_conversion_language = "en";
var google_conversion_format = "3";
var google_conversion_color = "ffffff";
var google_conversion_label = "bSpUCOP9iAIQpevy2QM";
/* ]]> */
</script>
<script type="text/javascript" src="http://www.googleadservices.com/pagead/conversion.js">
</script>
<noscript>
<div style="display:inline;">
<img height="1" width="1" style="border-style:none;" alt="" src="http://www.googleadservices.com/pagead/conversion/993834405/?label=bSpUCOP9iAIQpevy2QM&amp;guid=ON&amp;script=0"/>
</div>
</noscript>

Pretty standard stuff. So, what I'm trying to do is insert this into the results page using the callback method (which is provided). Frankly, I'm redirected no matter when I try to insert this code using js or jQuery (either on original page load or in the callback) so maybe the callback bit is irrelevant, but it's why I'm not just pasting it into the page's code.

I've tried a number of different ways to do this, but here's what I currently have (excuse the sloppiness. Just trying to hack my way through this at the moment!):

function matchResultsCallback(data){

    var scriptTag = document.createElement('script');
    scriptTag.type = "text/javascript";
    scriptTag.text = scriptTag.text + "/* <![CDATA[ */\n";
    scriptTag.text = scriptTag.text + "var google_conversion_id \= 993834405\;\n";  
    scriptTag.text = scriptTag.text + "var google_conversion_language \= \"en\"\;\n";   
    scriptTag.text = scriptTag.text + "var google_conversion_format \= \"3\"\;\n";
    scriptTag.text = scriptTag.text + "var google_conversion_color \= \"ffffff\"\;\n";
    scriptTag.text = scriptTag.text + "var google_conversion_label \= \"bSpUCOP9iAIQpevy2QM\"\;\n";
    scriptTag.text = scriptTag.text + "/* ]]> */\n";
    $('body').append(scriptTag);

    $('body').append("<script type\=\"text\/javascript\" src\=\"http://www.googleadservices.com/pagead/conversion.js\" />");
    //I have also tried this bit above using the same method as 'scriptTag' with no luck, this is just the most recent iteration.

    var scriptTag2 = document.createElement('noscript');
    var imgTag = document.createElement('img');
    imgTag.height = 1;
    imgTag.width = 1;
    imgTag.border = 0;
    imgTag.src = "http://www.googleadservices.com/pagead/conversion/993834405/?label=bSpUCOP9iAIQpevy2QM&amp;guid=ON&amp;script=0";

    $('body').append(scriptTag2);
    $('noscript').append(imgTag);
}

The really odd thing is that when I only insert one of the script tags (it doesn't matter which one), it doesn't redirect. It only redirects when I try to insert both of them.

I've also tried putting the first script tag into the original page code (as it's not making any calls anywhere, it's just setting variables) and just inserting the conversions.js file and it still does the redirect.

If it's relevant I'm using Firefox 3.6.13, and have tried the included code with both jQuery 1.3 and 1.5 (after realizing we were using v1.3).

I know I'm missing something! Any suggestions?

Answer 1

All I do is return the code (or in our case, an image) along with the "success" message in the callback.

When a contact form is submitted, or a registration form filled out and submitted, we post to a php script using jQuery, then output a "thank-you" message to a div:

"$first_name, Thanks for requesting more information. A representative will contact you shortly."

... followed by the 1x1 gif Google provides.

Here's the jQuery:

$.post('script.php',{'first_name':first_name,'last_name':last_name,'email':email,'phone1':phone1,'password':password,},function(data){
var result=data.split("|");
if(result[0] ==='success'){
$('#return').html(result[1] + $result[2]);

And the php...

echo 'success|'.$first_name.', Thanks for requesting more information.
A representative will contact you shortly.|<img height="1" width="1" alt="" src="http://www.googleadservices.com/pagead/conversion/xxxxxxxx/imp.gif?value=0&amp;label=xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx&amp;script=0"/>';

You might need to throw in a "document.location.reload();" if it isn't being picked up by google

Answer 2

I tried all the ways to manually include conversion.js, it all loaded the script, but didn't further execute what we needed inside the script, there's a simple solution.

Just put your conversion code in a separate HTML, and load it in an iframe.

I found code to do that at http://www.benjaminkim.com/ that seemed to work well.

function ppcconversion() {
var iframe = document.createElement('iframe');
iframe.style.width = '0px';
iframe.style.height = '0px';
document.body.appendChild(iframe);
iframe.src = '/track.html'; // put URL to tracking code here.
};

then just call ppcconversion() wherever in the JS you like to record it.

If you're using jQuery in your pages, why don't you use the getScript method of the same to poll the conversion tracking script after setting the required variables?

This is what I usually do, once I've received a success response from my AJAX calls.

var google_conversion_id = <Your ID Here>;
var google_conversion_language = "en";
var google_conversion_format = "3";
var google_conversion_color = "ffffff";
var google_conversion_label = "<Your Label here>";
var google_conversion_value = 0;
if (100) {
    google_conversion_value = <Your value here if any>;
}
$jQ.getScript( "http://www.googleadservices.com/pagead/conversion.js" );

This works just fine for me. If you want a more detailed example:

$.ajax({
    async:      true,
    type:       "POST",
    dataType:   "json",
    url:        <Your URL>,
    data:       _data,
    success:    function( json ) {

            // Do something
            // ...

            // Track conversion
            var google_conversion_id = <Your ID Here>;
            var google_conversion_language = "en";
            var google_conversion_format = "3";
            var google_conversion_color = "ffffff";
            var google_conversion_label = "<Your Label here>";
            var google_conversion_value = 0;
            if (100) {
                google_conversion_value = <Your value here if any>;
            }
            $.getScript( "http://www.googleadservices.com/pagead/conversion.js" );

        } // success
});

If you use other libraries such as Mootools or Prototype, I'm sure they have similar in-built methods. This AFAIK is one of the cleanest approaches.

For anyone still looking for a good solution to this, Google supports AJAX Conversions natively now through their Google Analytics API.

You can do it by making a event API call in Google Analytics. What you do is setup an Analytics event, tie it to a goal, then import that goal into AdWords as a conversion. It's a bit of a lengthy process but it's a clean solution.

Answer 5

As you have seen, the google conversion tag only calls on a redraw. I had to make sure it was called when a part of a page was redrawn. (Due to some bad website design that I could not fix at the moment.) So I wrote a function to call from an onClick event.

Essentially, all you have to do is to call doConversion();

Here is what we ended up with:

    // gothelp from from http://www.ewanheming.com/2012/01/web-analytics/website-tracking/adwords-page-event-conversion-tracking

    var Goal = function(id, label, value, url) {
    this.id = id;
    this.label = label;
    this.value = value;
    this.url = url;
    };

function trackAdWordsConversion(goal, callback) {
// Create an image
var img = document.createElement("img");

// An optional callback function to run follow up processed after the conversion has been tracked
if(callback && typeof callback === "function") {
    img.onload = callback;
}
// Construct the tracking beacon using the goal parameters
var trackingUrl = "http://www.googleadservices.com/pagead/conversion/"+goal.id;
trackingUrl += "/?random="+new Date().getMilliseconds();
trackingUrl += "&value="+goal.value;
trackingUrl += "&label="+goal.label;
trackingUrl += "&guid=ON&script=0&url="+encodeURI(goal.url);
img.src = trackingUrl;

// Add the image to the page 
document.body.appendChild(img);

// Don't display the image 
img.style = "display: none;";
    }
function linkClick(link, goal) {
try {
    // A function to redirect the user after the conversion event has been sent
    var linkClickCallback = function() {
        window.location = link.href;
    };

    // Track the conversion
    trackAdWordsConversion(goal, linkClickCallback);

    // Don't keep the user waiting too long in case there are problems
    setTimeout(linkClickCallback, 1000);

    // Stop the default link click
    return false;
} catch(err) {
    // Ensure the user is still redirected if there's an unexpected error in the code
    return true;
}
}
function doConversion() {
var g = new Goal(YOUR CODE,YOUR_COOKIE,0.0,location.href);
return linkClick(this,g);
}

Answer 6

this simple code worked for me (the $.getScript version didn't).

var image = new Image(1,1);
image.src = 'http://www.googleadservices.com/pagead/conversion/' + id + '/?label=' + label + ' &guid=ON&script=0';
