The metric uses comScore’s multi-platform audience de-duplication methodology combined with comprehensive tagging to produce a measure of unique people being reached across the globe. This covers reach across PCs, laptops, smartphones and tablets and accounts for website, app and video audiences.

The initiative has been tested in partnership with MailOnline.

“As more and more websites compete in a global marketplace, we are very excited to provide a credible and independent international audience reach number across all platforms and geographies,” said Mike Pilcher, senior vice president Sales EMEA at comScore.

“We believe this approach offers great potential to other global media brands seeking to present their full offering to pan-national advertisers and their agencies.”
