Depending on your site's topic, certain data such as an office address or detailed parameters for particular pages can be used as markup content.
These types of data may be used to better represent your site in search results (by creating special snippets) and may also be used in other Yandex services. Each type of data is processed in its own way. If you would like to read more about rules for sending data and how data is used by Yandex, please read the appropriate help section.

On the Site contents page you can choose the appropriate type of additional information and click on the corresponding point. Afterwards you will see instructions on how to add the corresponding data type.
