Facebook Says It Gave Advertisers Inflated Video Metrics


Facebook Inc.s rapid growth has been tightly linked to convincing advertisers that people are watching more videos on its social network. Now the company is disclosing it has been giving marketers an inflated number for the average time being spent viewing online clips.

The company, owner of the worlds largest social network, boosted the figure by only counting a video as viewed if it had been seen for more than 3 seconds. Not included in the calculation was when a person didnt watch — or watched for less than 3 seconds. Facebook said it was taking steps to fix the problem and that advertisers werent overcharged.

As soon as we discovered the discrepancy, we fixed it, David Fischer, Facebooks vice president of business and marketing partnerships, said in a statement Friday. We informed our partners and made sure to put a notice in the product itself so that anyone who went into their dashboard could understand our error.

After reviewing other metrics, Facebook concluded that the error had no impact on video statistics the company has shared in the past, such as time spent watching video or the number of video views, according to the statement.

The disclosure may hurt Facebooks effort to get marketers to augment television campaigns, which carry the largest budgets in advertising, with clips on its social network. The metric Facebook has been giving advertisers doesnt include the roughly 80 percent of people who dont watch online videos at all, or quickly browse past them, according to Rob Norman, chief digital officer at GroupM, an advertising company.

Nobody is saying Facebook is defrauding anybody, but what they are doing is giving specific measurements which some people may find misleading, Norman said.

Facebooks stock fell 1.7 percent to $127.87 at 2:43 p.m. in New York. The stock had gained 24 percent this year through Thursdays close.

Measuring Consumption

How to classify online video consumption is important to marketers and has long been a source of contention in the industry, Norman said. Figures that show people are, on average, spending a longer-than-expected amount of time viewing an ad may lead a brand to budget more because it shows potential customers are paying attention.

If you get a report that says your reach on television was 70 percent of your audience, and that by adding Facebook youre reaching 80 percent of your audience, you may spend more, Norman said.

Martin Sorrell, chief executive officer of WPP Plc, the worlds largest advertising company, said Facebooks miscalculation increases the need for an independent body like ComScore Inc. to play a bigger role in overseeing important metrics.

We have also been calling for a long time for media owners like Facebook and Google not to mark their own homework and release data to ComScore to enable independent evaluation, said Sorrell, whose company owns GroupM and has invested in ComScore. The referee and player cannot be the same person.

Facebook disclosed the issue in a posting on its advertiser help center web page several weeks ago. Big advertising buyers and marketers are upset about the inflated metric, and asked the company for more details, according to the report in the Wall Street Journal, which first reported the metric issue.

Media Impact

Facebooks publishing partners are affected by the error as well. News outlets like the New York Times are under increasing pressure from advertisers to prove that their online videos are actually seen by readers for more than a split-second. If Facebooks data about video viewing is inaccurate or incomplete, those companies may decide to put more videos on other platforms like YouTube. However, Facebook has become such a dominant source of traffic for publishers that they may have little choice but to accept Facebooks mistake and move on.

Think of the advertising dollars that flowed to Facebook because of the inflated growth in their videos, said Jason Kint, chief executive officer of Digital Content Next, a trade group that represents publishers like the New York Times, Washington Post and Bloomberg. Advertisers could have used the funds on TV or video elsewhere on the web, he said. Referring to media companies, he said: Thats money out of their pockets.

The social network, which has more than 1.7 billion users, has been making video a centerpiece of its strategy, and its robust growth in mobile advertising has been driven by strong demand for video spots. Chief Executive Officer Mark Zuckerberg said in July he wants Facebook to be a video-first company — and the news feed is likely to be mostly video in a few years.

Facebooks executives are set to meet with their top advertisers in New York next week during the Advertising Week conference.
