Data: Voice search in United States digital media outlets. Use of the "speakable" markup

This dataset explores how U.S. digital media outlets use the "speakable" semantic markup for voice search. Its use is intended to attract informational content to Google Assistant and Google Home devices, while it is also considered a necessary strategy for voice search optimization (VSO). The analysis of the use of this markup is limited to 50 U.S. media outlets because it is currently only implemented in this geographic area. In this study, 372,000 news items were analyzed with the SEO tool Screaming Frog.
