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.本数据集探究了美国数字媒体机构如何针对语音搜索使用可朗读语义标记（speakable semantic markup）。该标记的应用旨在将资讯内容引流至谷歌助手（Google Assistant）与谷歌家居（Google Home）设备，同时也被视为语音搜索优化（VSO）的必要策略。由于该标记目前仅在该地理区域落地应用，因此本次分析仅覆盖50家美国媒体机构。本研究借助SEO工具Screaming Frog，对37.2万条新闻内容进行了分析。
