Google’s help document has been updated on using “how-to” structured data with new guidelines about things people should try avoiding.
How-to structured data is a type of markup that communicates to Google that a piece of content is a how-to article.
By using how-to mark up, it makes a page eligible to appear in search as a rich result.
Lizzy Harvey, a technical writer at Google, sent out a tweet yesterday notifying everyone about the updates. She also updated the mobile-first indexing document to align with yesterday’s announcement.
So if you have a how-to guide with multiple sets of instructions, it may be best to separate them into several pages if you plan on using how-to markup.
