Google – and by extension YouTube – have been trying to get accurate Nielsen ratings for months, and are finally confident enough in the system to begin selling ratings next month. The Online Campaign Ratings product features pre-roll ads on the video platform, and will include guarantees to advertisers starting n month from today. By the end of the year, Google wants to have OCR directly integrated into the Doubleclick platform, so advertisers will be dealing directly with Nielsen ratings in their plans. If the deal is as set in stone as Google is portraying, it would mean deliverable metrics for advertisers looking to expand their online presence and digital campaigns in a fashion that is designed to guarantee results. As OCR and this type of technology develops, the more granular marketers can get about their strategies.
