What is the critical render path?

Resource Description Frameworks (RDFa) is conceptually similar to Microdata. The primary difference is the syntax and how to implement the code. Therefore, some developers might prefer to use either this or Microdata and both work fine.

This code is not interchangeable with the Microdata syntax, so the rule of thumb is to pick one and stick with it. Microdata is the more popular syntax, so I would recommend that you use that instead.

How can I check my Resource Description Frameworks?

The easiest way to check structured data is by using Google’s Structured Data Testing Tool. Directly input a URL or copy and paste your code, and it will notify you of any errors, warnings and suggestions.

The most common errors are to do with the formatting of the code. Tools that automatically generated structured data can often include mistakes. An excellent example of this is missing required fields such as the name of a product, or bad formatting of JSON code.

The most frequent warnings include other useful data for the object type. An excellent example is suggestions for GTIN or SKU codes on the product markup.
