Prebid Click Tracking

[AStephenson]

How can I track prebid clicks in GAM? The bidder is AppNexus. Creative is below, but I am unsure where to put the click tracker in the creative tag.

<script src = "https://cdn.jsdelivr.net/npm/prebid-universal-creative@latest/dist/creative.js"></script>

<script>
  var ucTagData = {};
  ucTagData.adServerDomain = "";
  ucTagData.pubUrl = "%%PATTERN:url%%";
  ucTagData.adId = "%%PATTERN:hb_adid_appnexus%%";
  ucTagData.cacheHost = "%%PATTERN:hb_cache_host_appnexus%%";
  ucTagData.cachePath = "%%PATTERN:hb_cache_path_appnexus%%";
  ucTagData.uuid = "%%PATTERN:hb_cache_id_appnexus%%";
  ucTagData.mediaType = "%%PATTERN:hb_format_appnexus%%";
  ucTagData.env = "%%PATTERN:hb_env%%";
  ucTagData.size = "%%PATTERN:hb_size_appnexus%%";
  ucTagData.hbPb = "%%PATTERN:hb_pb_appnexus%%";
  // mobileResize needed for mobile GAM only
  ucTagData.mobileResize = "hb_size:%%PATTERN:hb_size_appnexus%%";
  try {
    ucTag.renderAd(document, ucTagData);
  } catch (e) {
    console.log(e);
  }
</script>

Someone with javascript chops might be able to add some code that listens for click events?

Maybe set a variable like

var gamClickTracker="%%CLICK_URL_UNESC%%"; // this will be resolved by GAM

//pseudo-code!
listenToClickEvents() {
   fire gamClickTracker;
}

Do you just want the clicks tracked in GAM, in the bidder reports, or in a Prebid Analytics report?

Tracked in GAM. Thanks!

I don't think that works @bretg as I don't think there is an event to listen to

I think #5796 is more likely to succeed, but requires the ssp to deliver specific markup

I was thinking something like this -- https://stackoverflow.com/questions/2381336/detect-click-into-iframe-using-javascript/32138108#32138108

Prebid creatives are wrapped in an iframe, so maybe there's something we can do to detect clicks on that iframe without affecting the rest of the page?

So I have been digging into this a bit and the <iframe> html tag supports global and event attributes so you are fine attaching event listeners to them like some of the above StackOverflow solutions. It seems like people are approaching this in generally 2 different ways.

One way seems to be setting the focus and then listening to blur and focus events but when I was trying this with multiple iframes I was getting some weird interactions but could have just been me.

Another way that I seemed to have a bit more success with was defining an object with fields related to different mouse events and then setting those to true or false using different event listeners. You can then build functions off the main object to send the data around.

I haven't been able to figure out how to communicate this back to GAM though yet

That link is fascinating, thanks Bret! There are a bunch of solutions there. I would think we would want %%CLICK_URL_ESC%% to be added to the creative in gam and then passed up in the post message, and secure_creatives.js would need to receive it, does that sound right?

A few links and implementations exampled in this issue for reference

[patmmccann]

I don't see the resolution here, are you closing as 'won't do'

@ChrisHuie - the goal here would be to add some documentation on the site giving an example and/or guidance. If you can post your experiments here, we can discuss how best to document.
