Google is currently sending out warnings about navigation path problems through Search Console
With this, Google would like to point out that they are concentrating on the schema.org schema when developing the crawler and no longer support metadata from the outdated namespace data-vocabulary.org .
Google made the change on April 6, 2020. Since then, only the more widely used schema.org schema has been supported by the search engine.
What are structured data such as schema.org ?
Structured data are instructions to search engines about the specific meaning of data and how it relates to other data.
Without becoming too theoretical: This means that data can be given separately on one page. In the case of an eShop, for example, the title, article number, price, etc. can be given to the search engine without the crawler having to read out the information in the text on the page. The latter is not that easy at all. This might still be possible with prices, but with article numbers the question arises where it is and what does it look like. In order to solve the problem exactly, there is structured data (see also ontology at Wikipedia ).
Do I have to do something about it?
It is not entirely clear to me who exactly receives the message. Maybe they all get webmasters. If you have received this message, it does not mean that you have an acute problem.
If the CMS / ESHOP or the SEO plugin that you are using supports schema.org metadata, then you do not need to do anything else. If it is a current version, this should be the case. The developers of an actively developed system are usually in the know and develop the software according to the current standards.
To test structured data on your own data, Google offers the online tool to test structured data (external link). If data about products (in the case of an online shop), such as titles, prices, etc. appear, everything is fine.
The current version of WooCommerce supports the schema.org schema. WordPress can be supplied with structured data according to schema.org with the help of YOAST SEO. Further information is available from YOAST under this link: Structured data with Schema.org: the ultimate guide (external link).
