Validation of semantic markup Yandex and Google

Semantic markup will tell search engines a maximum of useful information in a structured form. No matter how good search engines are, they cannot determine the purpose and ownership of information. For example, when a search engine sees the date, it won’t be able to figure out what it is: the date the page was updated, the date the product was manufactured, or maybe it’s the date the product review was published. Semantic markup helps to clearly define what this or that information is. This helps search engines better understand the content of the site, which is why they often show you for low-frequency queries.
