Structured data is a crucial component of technical SEO for voice search. It provides context to search engines and helps them understand a website's content. Structured data implementation involves adding code to a website that helps search engines identify important information such as business name, address, phone number, and other relevant details.

By implementing structured data, businesses can improve their chances of appearing in voice search results. This is because voice assistants rely heavily on structured data to provide relevant answers to user queries. Therefore, ensuring that structured data is implemented correctly on a website is important.
