How viral is your viral?

Video analytics firm Visible Measures is launching a service that enables advertisers and agencies to measure the viral reach and audience engagement of video campaigns, reports MediaPost.

Visible Measures' technology monitors user engagement in a given video stream. Its Viral Reach Database, which tracks the performance of 80 million unique videos across 150 video-sharing sites, serves as a yardstick against which video ad campaigns can gauge their progress.

The company is currently working with a handful of large agencies, such as Hill Holliday, to tailor the offering to client needs.
