Every month I write a column for MediaPost’s Metrics Insider.  This month I wanted tackle my evolving take on Internet video measurement.  Very few companies offer solutions in this space.  Only a few are really differentiated.  Check out Visible Measures, NedStat, TubeMogul, Divinity Metrics, and the usual suspects, Omniture, Unica, WebTrends, ComScore, and Neilsen NetRatings. 

Here’s my column:

IN LATE 2007, THE DIGITAL Video Barometer Executive Survey indicated that more than 80% of media and entertainment executives believe tracking, measuring, and monitoring Internet video content is critical to bottom-line profit.  That’s not surprising. Accurate measurement informs decision-making and improves business performance, and Internet video is more mainstream and popular than ever before.  What may be surprising to those executives is that technology for measuring Internet video generally focuses on video content served on-site, not off-site.  It’s fairly straightforward for a Web analytics tool to tell you how people are consuming and interacting with on-site video, but consumption and interaction of videos distributed across multiple sites, perhaps virally or via social media campaigning, aren’t directly measurable by Web analytics tools.  Panel-based technologies can approximate certain off-site measures of video consumption and distribution, but don’t provide very deep on-site metrics. Measurements of Internet video consumption, interaction, and distribution may be categorized as follows:

• Instream measurement.  Refers to measuring the video itself and the various events and behaviors that occur during a video viewing experience, such as time-based duration metrics and interaction and behavioral metrics (for example, the number of stops, plays, pauses, rewinds, fast-forwards, sites that posted or syndicated the video, clicks on hotspots and social media features).
• Outstream measurement.  Refers to measuring the content environment and user experience surrounding the video on the site or in the skin, such as the conversion metrics (percentage of visitors downloading or viewing a video), source metrics (refers to the video page, players used), and content metrics (percentage videos viewed by topic, percent videos viewed by file type). 

Those categories form a framework for Key Performance Indicators (KPI’s) that help to identify how people interact with videos, how videos perform when compared to other videos, and against pre-defined business goals.  Analysis of KPIs enables video content to be tailored to maximize performance.  Example KPI’s include:

Instream KPI’s:

• Percent high, medium, and low duration video views
• Average viewing time per video
• Percent visitors who complete the video
• Percent visitors that stop the video within 10 seconds
• Percent visits when this video was the last video viewed
• Percent visits when this video was the first video viewed

Outstream KPI’s:

• Conversion rates by video, topic, channel, taxonomy node, referrer, geography, keyword, and so on
• Average video views per visit
• Percent visits/views from different channels (such as email/rss, organic search, paid search, direct)
• Average time between visits that include a video view
• Repeat visit rate for visits involving a video view or download

These KPIs are measurable using a Web analytics tool, and perhaps a few of them are possible using traditional panel-based measurement.  But if off-site video distribution creates a whole new set of challenges to using current analytics and audience measurement tools to track instream and outstream metrics and KPIs, what are publishers and advertisers to do?  It’s a business problem that demands a new technology solution for understanding audience behavior, consumption, and distribution patterns of off-site syndicated or viral video content.

So what would a new technology solution for measuring Internet video and audience behavior do?  First it would have to fill the gap between panel and census-based measurement systems in a way that helps both publishers and advertisers  – not just one or the other — understand audience reach, frequency, and behavior.  The technology must enable tracking and actionable reporting and dashboarding of key metrics and KPIs, distribution patterns, behaviors, and interactions regardless of where the video “goes” on the Internet.  Audience characteristics from external databases (like OpenID for example) and internal company databases (like subscription and registration dbs) should be able to be integrated with data collected about behavior, video metadata, and instream and outstream metrics. 

If measuring digital video is as important as eight out of 10 media and entertainment executives believe it to be, there are some huge money-making opportunities on the horizon — for companies that are already providing technology for tackling this emerging business need, for advertisers using Internet video to drive awareness and response, and for measurement professionals who can help make sense of the Internet video ecosystem, solve measurement challenges, identify significant business opportunities, and use video metrics to improve business performance.  We’re certainly at the beginning of the J-curve for Internet video measurement for both publishers and advertisers.  After all, Forrester predicts Internet video advertising spend to increase from $471 million last year to $7.1 billion in 2012. 

About a year ago, I wrote a guest blog post over on Robbin Steif’s blog about using Google Analytics for tracking Javascript and Flash events.  This weekend Jeremy Geelan, SVP over at Sys-Con Media, asked if he could republish the work.  Of course I said “yes.”  Then I noticed that a lot has happened to GA in a year (and more to come, ahem, API’s!).  What I had wrote was now incomplete, so what you’ll find below is my attempt to sum up “event tracking” using ga.js and the Great Google’s Event Tracking Data Model.  Let me know how I did covering it, and if you think I should clarify of expand on anything.

Since we all know about page tags, let’s get down to business with “the Google” and how it tracks “the Rich Media.”  Google Analytics currently has two different javascript page tags:

• urchin.js.  The legacy version of the Google Analytics page tag.
• ga.js.  The current, rebranded version of the Google Analytics page tag.

How you track rich media depends on which page tag you are using.  I’ll discuss using urchin.js first, then ga.js.  I’ll also provide some information about Google’s Event Tracking function for capturing specific “events” within their event architecture.

Tracking Rich Media using Urchin.js

In the legacy version of Google Analytics, the smarties at Google created a little JavaScript function called urchinTracker() that enables event tracking.  Use the JavaScript function with an argument specifying a name for the event. For example, the function:

javascript:urchinTracker(’/mysite/flashrichmedia/playbutton’); 

logs each occurrence of that Flash event as a page view of:

/mysite/flashrichmedia/playbutton

Some caveats:

1. Always use a forward slash to begin the argument.
2. Actual pages with these filenames do not need to exist.
3. You can organize your events into any structure or hierarchy you want.

Important: Google says to place your tracking code “between the opening tag and the JavaScript call” if your pages include a call to urchinTracker(), utmLinker(), utmSetTrans(), or utmLinkPost(). For example, if the page view is the major event and the “play” event a minor event; then, your hierarchy would be Page View > Event, where the page contains an event, such that:

/mysite/ria_bittons/playbutton
/mysite/ria_bittons/pausebutton
/mysite/ria_bittons/playbutton
/mysite/ria_clips/clip

Some examples of the code (from Google Help):

on (release) {
// Track with no action
getURL(”javascript:urchinTracker(’/folder/file’);”);
}

This one above tracks when you click and release (although technically, it just notices the release) of a flash button (and records the file you specify as a page view).

on (release) {
//Track with action
getURL(”javascript:urchinTracker(’/folder/file’);”);
_root.gotoAndPlay(3);
myVar = “Flash Track Test”
}

The second one is the same, but by using a function, passing it a parameter, and identifying the instance you want to track, you can measure when your file was used in a specific scene in a little flash movie. So it is a more specific method for handling event tracking in Flash.

onClipEvent (enterFrame) {
getURL(”javascript:urchinTracker(’/folder/file’);”);
}

And the third one repeats the action throughout the movie so that each time the file is loaded, it gets tracked as an event. If you were to pass a unique file at the end of the movie, you could recognize it using this method (or the other methods) to know that the whole movie was watched (as long as your session doesn’t time out). Next, wait until Google updates your analytics, then check the Top Content report to see if it all worked. Now let’s discuss how to the exact same thing using the new trackPageview function released with ga.js.

Tracking Rich Media using ga.js

In the current version of Google Analytics, the brainiacs at Google created a little JavaScript function called trackPageview() that enables event tracking.  Use the JavaScript function with an argument specifying a name for the event.For example, the function:  

javascript:pageTracker._trackPageview (“/mysite/flashrichmedia/playbutton”);

logs each occurrence of that Flash event as a page view of:

/mysite/flashrichmedia/playbutton

Some caveats:

1. Always use a forward slash to begin the argument and use quotes around the argument.
2.  Actual pages with these filenames do not need to exist.
3. You can organize your events into any structure or hierarchy

You must put calls to _get._getTracker and _initData above the call to _trackPageView.  For example, you would insert the following code:

<script type=”text/javascript”>
var pageTracker = _gat._getTracker(”UA-xxxxxx-x”);
pageTracker._initData();
pageTracker._trackPageview();
</script>

Here are some examples of the ga.js code (from Google Help) that replicate what I described above using the most recent code:

on (release) {
// Track with no action
getURL(”javascript:pageTracker._trackPageview(’/folder/file.html’);”);
}

This one above tracks when you click and release (although technically, it just notices the release) of a flash button (and records the file you specify as a page view).

on (release) {
//Track with action
getURL(”javascript:pageTracker._trackPageview(’/folder/file.html’);”);
_root.gotoAndPlay(3);
myVar = “Flash Track Test”;
}

The second one is the same, but by using a function, passing it a parameter, and identifying the instance you want to track, you can measure when your file was used in a specific scene in a little flash movie. So it is a more specific method for handling event tracking in Flash.

onClipEvent (enterFrame) {
getURL(”javascript:pageTracker._trackPageview(’/folder/file.html’);”);
}

And the third one repeats the action throughout the movie so that each time the file is loaded, it gets tracked as an event. If you were to pass a unique file at the end of the movie, you could recognize it using this method (or the other methods) to know that the whole movie was watched (as long as your session doesn’t time out).

Tracking Rich Media using Google Analytics Event Tracking

When Google released ga.js in fourth quarter 2007, Google also released a data model for tracking events.  It provides more flexibility and ease of customization than the methods I described above.   The data model makes use of:

• Objects. These are named instances of the eventTracker class and appear within the reporting interface.

var videoTracker = pageTracker._createEventTracker(”Movies”);

• Actions. A string you pass to an event tracker class instance as a parameter.

videoTracker._trackEvent(”Stop”);

• Labels. An optional parameter you can supply for a named object.

downloadTracker._trackEvent(”Movies”, “/mymovies/movie1.mpg”);

• Values. A numerical value assigned to a tracked object.

To set up event tracking you should:

1. Identify the events you want to track.
2. Create an event tracker instance for each set of events.
3. Call the _trackEvent() method on your page.
4. Enable “event tracking” in your profile.

To instantiate an event tracker object, you might do something like this:

var myEventObject = pageTracker._createEventTracker(”Object Name”);
myEventObject._trackEvent(”Required Action Name”, “Optional Label”, optionalValue);

createEventTracker() is order dependent and must be called after the main tracking code (ga.js) has been loaded.Next you would call the _trackEvent() method in your source code either on every page that contains the event or as part of the tracking code for every page:

_trackEvent(action, optional_label, optional_value)

If you wanted to track interaction with the Flash UI, such as the button on a Flash Video Player, you would create a videoTracker object with name “Video”:

var videoTracker = pageTracker._createEventTracker(’Video’);

Then, in your Flash code for the video player, you would call the videoTracker object and pass a value for the action and label for the event:

onRelease (button) { 
   ExternalInterface (”javascript:videoTracker._trackEvent(’Play’, ‘MyVideo’);”)
}

You could also use the ExternalInterface ActionScript function as an eval() function to parse FlashVars and attach them to every Flash UI element that needs a tracking action.  For example, the code below associates a Stop action for the Video object and retrieves the provided label and value from the FlashVars:

onRelease (button) { 
   ExternalInterface (”javascript:videoTracker._trackEvent(’Stop’” + label + “,” + value + “);”)
}

Adding event tracking code would generate event reports in the Content section of the Google Analytics Interface.  Pretty cool stuff, Google!

Measuring video content with web analytics isn’t super difficult, but it has its nuances and challenges.  I’ve been thinking a bit about it lately, and have had some good conversations with a few people.  Folks I know are playing around with the likes of Joost, Vuze, and Hulu, TVUNetworks, as well as using BrightCove and Videoegg.  And, man, the popularity of BitTorrent and other swarm structure 4th gen P2P networks is larger than ever.

Simply speaking video measurement can be divided into the following types:

• Instream measurement.  Refers to measuring the video itself and the various abstract elements of the video experience, such as duration metrics (average viewing time) and interaction metrics (number of stops, plays, pauses, rewinds, fast forwards, and clicks on video content).
• Outstream measurement.  Refers to measuring the content environment and user experience surrounding the video, such as the conversion metrics (percentage of visits downloading or viewing a video), behavioral metrics (referrers to the video page, players used), and content metrics (percentage videos per channel, percentage videos viewed by topic, percent videos viewed by file type). 

By categorizing the web video analytics into these two buckets, you are better able to answer meaningfully the following questions, which must be considered prior to any rollout:

1. What are the business objectives for rolling out video features on the site?
2. What format are the videos in?
3. Are the videos downloads or streams?
4. Am I using a content distribution network or streaming video network?
5. Does my web analytics tool have the features necessary for video measurement? Or should I look for a third party, niche vendor?
6. What data collection method should I use?
7. Do I understand event models?
8. What KPI’s are relevant and important based on my business goals?

To help you formulate answers to those questions, here’s some thinking:

• Business objectives.  You, the analyst, must understand why your company is rolling out video.  In other words, what’s the goal and what strategy underpins the goal?  While video is “the rage” right now, simply rolling out video because “everyone is doing it” is no strategy (though doing so may yield a strategy ;).  A goal for video deployment could be “to generate leads,” thus you measure the scenario conversion rate for the funnel resulting in the lead generation and video download (outstream video analysis).  The objective might be “to keep visitors on the site longer,” then you would measure duration and interaction (instream video analysis).  As you all know, I firmly believe that it the business goal that allows you to contextualize what you’re measuring so that you may build KPI’s.
• Video format. Lots of different video file types exist: mpegs, qt, mov, swf, flv, avi, wma, ra, wmf, mp4 and more.  You’ll need to identify the video types you want to track so you can configure your web analytics tool to measure them.  Removing or adding filters or changing your tag’s javascript might be necessary. 
• Download or streams.  Videos can be downloaded (by right clicking) or spawned in a media player.  They can also exist embedded on the page or in another object for on-page streaming.  Thus, the way you instrument your pages will differ based on the way you present the video content. For example, if you are streaming videos, you may want to use javascript (or a vendor provided scripting language) to instrument your pages to track the video.  If you are just hosting downloads, you may simply want to run your logs to detect the number of times videos were downloaded.
• Content distribution network or video network. If your video content is distributed by a CDN or a video network, you will have to apply page tags on all the pages rendered by combining your server’s content with the content served by the CDN. Some video networks provide basic reporting that you can extend with a client-side page tagging solution.  Alternatively, you can process the logs provided by a CDN. The challenge with CDN log file processing is that you will most likely not be able to merge the data with your log files for the same site, resulting in two “profiles” of analytics data related to one site: one profile with the site analytics data and one with the CDN analytics data.
• Data collection method.  If you’ve read this far in my blogivation, you probably picked up that the data collection method you have at your disposal will constrain or enable the way you measure video.  Page tags will enable you to instrument your pages with onclick functions that pass values to the javascript and in turn to the analytics server.  Packet sniffers and log files enable you to measure downloads without modifying code.   If you need modify your web analytics tool or tag configuration to track video filetypes, you can reprocess logs to access the data.  With tags any data related to downloads or interactions with the video object prior to the config change will be lost.
• Web analytics tool features. Many web analytics tools will allow you track a video play or download in your page view reports, but only two tools support true event models: Unica NetInsight and Google Analytics.  At Emetrics San Fran in May 2007, Ian Houston and I gave a preso on “from page views to events.”  It looks like the vendors agreed, ay? ;)
• Third party tools.  With the convergence of internet and television, we’re not many years away from having a single-screen for viewing the internet, tv, and movies.  Many of us already connect our TV’s to our computers (Windows Media Server), use Slingbox, have had Tivo for years, use BitTorrent and perhaps even consume content from the sites I listed at the beginning of this post.  Companies like Visible Measures, Zango, VidMetrix, and Maven Networks already provide some flavor of a video measurement solution too.
• Event models provide the conceptual and logical framework for measuring interactions that are subordinate, equal, or a replacements for the page view.  Without getting into much detail, “events” are interactions such as the play, stop, pause in a video stream, or the pan, zoom events in a online mapping experience.  In order to articulate the instream video experience, you should understand what an event model is and how it applies in Web Analytics 2.0.
• KPI’s.Based on business goals resulting from site strategy, you can build KPI’s related to instream and outstream video measurement.  For example:

Instream:

• Percentage high duration streams
• Percentage medium duration streams
• Percentage low duration streams
• Average viewing time per stream/overall across all streams
• Percentage visits who complete stream
• Percentage visits that stop stream within 10 seconds
• Percentage visits when this stream was the last video viewed
• Percentage visits when this stream was the first video viewed

Outstream:

• Conversion rates by video filetype, video topic, channel, taxonomy node, referrer, geography, keyword, and so on
• Average streams per visit
• Percent visits/views from different channels (such as email, organic search, paid search, direct, offline)
• Average time since last stream/video downloads
• Average time between stream/video downloads
• Repeat visit rate for visits involving a stream/video download

The Internet has come a long way since I saw my first streaming video over 9 years ago (VIVO for those old timers out there).  The options for consuming video content over the web are growing everyday (and not at all limited to YouTube, ay?).  I firmly believe video on the Internet is still in its infancy, and video measurement technologies both inside and outside of “web analytics” are quite embryonic.  What a huge space for growth! 

As the internet-originated video becomes even more pervasive for home entertainment and for business communication, companies will need to employ analysts who know how to create frameworks measuring video content.  Do you? 

One of the web analytics bloggers in my blogroll is Robbin Steif.  She runs LunaMetrics, leads the Marketing Committee for the Web Analytics Association, and was even recently elected to the Board of Directors for the Web Analytics Association.  Her history includes an impressive set of initialisms: IBM, HBS, MBA, CFO, CEO. 

A few weeks ago she invited me to guest blog on how to measure Rich Internet Applications and enable event tracking. The post evolved into a three-part series:

• Rich Internet Apps for Beginners, Part I of III: What is it?
• Rich Internet Apps for Beginners, Part II of III: Google Analytics
• Rich Internet Apps for Beginners, Part III of III: Unica

Check Robbin out at Emetrics in San Francisco.  She’s going to tell you how to put your best foot forward and understand the wild, wide world of web analytics.  And, if you’re lucky enough to attend Emetrics, also come see me and Ian Houston on Wednesday, May 9th.  We’re going speak about Web 2.0 analytics and present a conceptual framework for measuring all the new and cool stuff going on today.
