What's the role of structured data and schema markup in optimizing for voice search?

Structured data and schema markup enhance voice search optimization by providing context to search engines. You can implement schema markup to define product attributes, reviews, prices, and availability. This technique aids voice assistants in delivering precise and relevant information to users.

On the other hand, structured data enables featured snippets — a common source for voice search responses. It leads to enhanced discoverability in voice search results. You need to regularly validate your markup for accuracy and compliance with evolving search engine standards.
