UK advertisers spent about £606 million on online ads last year that didn’t meet minimum viewability thresholds, according to the latest quarterly benchmark report from ad verification company Meetrics.
In the final quarter of 2016, only 49% of banner ads served met the IAB and Media Ratings Council’s recommendation that 50% of the ad was in view for at least 1 second. This was the same figure as Q3, which itself was a marginal improvement on the 47% in Q2, but a noticeable drop from the 54% viewability level in Q1 2016.
