7. How cross domain tracking works
• The sites create a shared cookie
• Webtrends analysis engine glues the data
together
8. Cookies
SiteA.com SiteB.com
Cookie store for siteA.com
on your computer Cookie store for siteB.com
on your computer
SiteB.com CANNOT read the data from the cookies set in
SiteA.com and vice-versa, Thus SiteB.com does not know if you
ever visited SiteA.com or what you did there
9. Cookies
SiteA.com SiteB.com
Webtrends.com Webtrends.com
Cookie store for siteA.com
on your computer Cookie store for siteB.com
on your computer
If SiteA.com and SiteB.com load Webtrends, a third-party cookie
(Webtrends) can be generated that allows data to be passed
(visitor id) between the sites. This allows cross-domain reporting.
10. Cookies
SiteA.com
Webtrends.com
Cookie store for siteA.com on Both can read the
your computer AND same 3rd party

11. Cross-domain limitations
• If third-party cookies are disabled or
blocked, cross-domain reporting will not
function.
13. Data Collection from iFrames
• iFrame Tracking
– Requires adding some code to the iFrame
• Method 1: Add full Webtrends code to iFrame
• Method 2: Add postMessage to iFrame
14. Method 1:
Add full Webtrends code to iFrame
• Requires code be added to the iFrame
• Larger foot print
• Acts as second page load when iFrame loads
• Needs to utilize 3rd party cookie for x-domain
15. Method 2:
Add postMessage to iFrame
• Requires code to be added to the iFrame
• Very small foot print
• Sends tracking message to parent window
so all tracking comes from the home domain
16. Data Collection from iFrames
SiteA.com
SiteB.com
<iframe id="myiframe" src="http://www.sweetspottaxidermy.com/testiframe.html" width="420" height="380"></iframe>
• Cross-domain iFrame pulls content from
one domain into another
17. Data Collection from iFrames
• If the third party can add some code to the
iFrame we can still track the visitor
behaviors.
• HTML5 provide us a mechanism for the
iframe to communicate with the parent
window with an event listener
18. Site B sends the tracking message to Site A
SiteA.com
<input type="Button" value="Test" name="Test"
SiteB.com onClick="dcsMultiTrack('DCS.dcssip',window.location.hostname,
'DCS.dcsuri',window.location.pathname,
'WT.ti',document.title,
'WT.event','Test Button',
'WT.dl','99')">
<script>
dcsMultiTrack = function() {
var m = Array();
// stringify the arguments
for (obj in arguments) m.push(arguments[obj]);
// send to the listner in the parent window
window.parent.postMessage([m], "*");
}
</script>
<script>
window.addEventListener("message", function(e) { Webtrends.multiTrack({argsa: e.data.split(",")}) } ,false);
</script>
21. Event Data Collection
• Its becoming ever more popular to collect
not only page load data, but event based
data to understand how visitor are
interacting with objects on pages
23. Event Data Collection
• Collecting event based data is easy with Webtrends!
– Track when a visitor clicks a checkbox in a filter object
jQuery Selector Webtrends Selector
jQuery('.filterOption').live('click', function (evt) { dcs.addSelector(‘.filterOption'’,
transform: function (dcsObject, o) {
var e = evt.target || evt.srcElement;
var e = o[‘element’];
Webtrends.multiTrack({
element: this, o.argsa.push ("DCS.dcssip", window.location.hostname,
argsa: ["DCS.dcssip", window.location.hostname, "DCS.dcsuri", window.location.pathname,
"DCS.dcsuri", window.location.pathname, "WT.ti", document.title,
"WT.ti", document.title, "WT.dl", "31",
"WT.dl", "31", "WT.e_nam", jQuery(e).text(),
"WT.e_nam", jQuery(e).text(), "WT.e_typ", 'filter',
"WT.e_typ", 'filter', "WT.e_state", ", e.checked?’true’:’false’);
"WT.e_state", e.checked?’true’:’false’] }
}) });
});
• Using this technique you can track almost any page event on any
object. (hoverovers, focus, clicks, tap, swipe, …)
24. Keys For Event Data Collection
• Set the page determination level!
– WT.dl defines if the hit is counted as a page
view or an event.
• 0 = page view
• Non-zero = event
– If you forget to set the dl value, your page
view will be inflated
26. Geek alert
!
There are 10 kinds of people,
those that will understand this
section and those that won’t
27. HTML5 Event Listeners To The Rescue
e.addEventListener('play', function () {h5v_tracking('play', e, states)})
Key HTML5 Video events
• Play
• Pause
• Error
• Timeupdate
• Seeking
• Seeked
• Ended
28. Bind to all the events
e.addEventListener('play', function () {multitrack(…)});
e.addEventListener('pause', function () {multitrack(…)});
e.addEventListener('ended', function () {multitrack(…)});
e.addEventListener('error', function () {multitrack(…)});
e.addEventListener('timeupdate', function () {multitrack(…)});
e.addEventListener('seeking', function () {multitrack(…)});
e.addEventListener('seeked‘, function () {multitrack(…)});

33. No Clear Standards - Yet

standard metrics
have yet to be
established. One-
third said their clients
considered unique viewers
to be the best way to
measure audience. Another
one-quarter said it was
target impressions.

34. Action Script (flash)
• Requires developers
integrate code into the
flash objects
• Use JavaScript
• Use Webtrends data
insertion API
• Use Hybrid model
36. Data Collection with Data Insertion
• Data collection with mobile apps is done
the same way as with Flash
• Collect data from almost ANYTHING using
the data collection API
37. Collect Data From Almost Anything
• This Power Point
presetation is being
tracked with a simple
macro and the data
insertion API
39. Top Take-Aways
• Cross-domain tracking requires 3rvd party
cookies
• iFrame tracking appears complicated, but its not
• Event level tracking is becoming more popular,
and it easy to implement
• Use the DC API for site assets that don’t support
JavaScript
• Video tracking is rapidly expanding
