How do you measure online video?
Thursday, October 28th, 2010Measuring the performance of an online video campaign can seem like a Las Vegas buffet; so much to choose from, that you are more than likely to end up with more on your plate than you can digest. But fear not! Not every metric is equally important, and only a few are critical to gauge the performance of your campaign.
In a new report “Measuring Video Ads: Metrics for Brand Advertisers”, eMarketer’s David Hallerman quotes a survey that asked advertisers which metrics they would consider most important for measuring online video. Not surprisingly, ‘user interaction’ came in first.
The majority of advertisers have hit the nail on its head; interaction is the most important metric that they should be measuring. The MediaMind equivalent, Dwell Rate, which measures mouse roll-overs lasting more than one second, indicates how many users have actually noticed the video, and was linked in previous research to a lift in brand metrics. Average Dwell Time, which is the MediaMind equivalent for ‘time spent’, was also rated by advertisers in the top three metrics.

While nearly all metrics on this list come as a standard from your campaign management platform, ‘increase in brand awareness’, which was rated as the second most important metric for online video, comes at a steep price. While there is no doubt that it may be the best measure for the branding effect of the video, it can only be obtained through expansive market research. When considering the accessibility of all other metrics, advertisers and marketers should consider whether ‘increase in brand awareness’ is worth the considerable extra cost.
‘Purchase’, typically used to measure direct response, was selected as the fourth most important metric. This shows that many advertisers and marketers still think about online video as a direct response medium, and not as a branding tool – equivalent to TV ads. ‘Completion Rate’ may pose a challenge for measuring online video as most users do not click stop, and the ad keeps playing as long as they are still on the page even if they are not watching.
Thus ‘Completion Rate’ may not be a sign that people watched the full video. Dwell Rate and Dwell Time may give a better indication of that. ‘Impact on search behavior’ is one of the most interesting metrics on the list. It enables advertisers to see whether users have retained the message from the video and what keywords they subsequently searched for. While it may require some work to drive insights from the overlap between search and display, it is one of the most powerful metrics for branding.
Last, the ‘number of times forwarded’ is a powerful metric to measure the viral effect of a video ad. However, the vast majority of users are not going to forward your video to their friends, and therefore this metric should complement the others, not replace them.
