You can use Data Highlighter to tag data about a book, such as its title, author, reviews, and reader ratings. Then Google can present your data more attractively -- and in new ways -- in search results and in other products. (Each Google product applies its own rules when deciding whether and how to display your data.)
You can use Data Highlighter to tag any of the data described in the table below. Each tag corresponds to a property in the schema.org/Book schema. The name of each tag is followed by the name of the schema.org property in parentheses. Required tags are listed in bold.
Note that the data you can tag with Data Highlighter is a subset of the properties in the schema.org schema.
If your site is missing any of the data described below, you can add missing data from Data Highlighter. If Data Highlighter has a low level of confidence in the tagged data, an alert icon () displays while you are creating a page set. Data Highlighter will still make the low-confidence data available to Google, but other Google products might not use it.
