Viewability by age and gender segments is now available for all computer display impressions in Digital Ad Ratings markets including the UK, US, France, Germany, Italy, Brazil, Canada and Australia.

“It’s extremely important to our clients to know whether their ads are viewable and that they’re being viewed by the audience they were intended for,” said Megan Clarken, executive vice president at Nielsen. “This is why we collaborate with a leading provider like Integral Ad Science to offer viewability as part of our Digital Ad Ratings service.

“The ability to offer clients the most complete measure of their advertising reach is another example of our commitment to bringing comprehensive third-party independent measurement to the marketplace.”
