HTML5 Edits

There are two basic edits needed for all Sizmek ads.

HTML5 Include Code:

At the top of your HTML doc you will need to add the following line. This covers all of the basic tracking and security code needed.

<script type="text/javascript" src=""></script>


The script is added on line 11 in the screenshot below.

Add the Click-through Code

  1. Inside the javascript file, you will need to add our clickthrough code. The Flash CC conversion process automatically creates a click function near the bottom of the doc. Look for "this.frame_0 = function()" to find it.
  2. Within that function you should replace the existing click code with the following:
this.clickthrough_btn.addEventListener("click", clickThroughFunc.bind(this));

function clickThroughFunc(){

In the screenshot below it is shown on line 22 thru 29.

QA your HTML5 Ad

For Standard Banners, QA is fairly simple. To tell if the ad is working correctly there are 2 things to look for. Does the landing page window open? Is the click being tracked?

  1. Click the Preview button at the bottom right of the Ad Creation window or select your ad from the Ad list and click Preview.
  2. Within the platform preview, you should be able to click the button and see your landing page open if you assigned a URL during the ad build process.
  3. To see if it is trackable, look in the Interactions Monitor in the right bar. When you click the button, you should see it say "Click."

Also in this right bar is your official ad size, all assets used, Ad ID, Ad Format, the click-through URL, etc.
