Validation microdata Google
Markup will tell search engines as much useful information as possible 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. Micro-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.
Here are some recommendations to follow:
- All pages, except the main one, must have BreadcrumbList markup. It helps search engines to index the site.
- All pages must have WebPage markup. It provides key information about your site, used by Google.
- 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 only supported 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- It is better to replace outdated vCard and hRecipe microformats with Organization and Recipe microformats.
