Micro-markup format requirements and recommendations
Markup describes the content of the page in a structured way. It also reports additional service data, such as the structure of the site. It can also accurately describe not only the contact details of the organization, but also the opening hours.
The top snippet shows a beautiful hierarchy of sections at the link location. This is done using BreadcrumbList markup. The bottom one shows just a link.
Here are some recommendations to follow:
- All pages, except the main one, must have BreadcrumbList markup. It helps search engines to index the site.
- Enter information about your company using the Organization schema or its subsidiaries on each page.
- There are special micro-markup formats for products, recipes, movies, and other types of information materials. For such pages, search engines display information in special graphic blocks. Read more about them you can read in the documentation Yandex, and Google.
- If the scheme assumes a large amount of text, then use the Microdata format. If not, use JSON-D.
- Refrain from using the RDF markup format. It is supported only by Google. Microdata and JSON-D formats are supported by both Yandex and Google.
- It is better to replace outdated vCard and hRecipe microformats with Organization and Recipe microformats.
