Gets the page's structured data.
The structured data on your page helps search engines understand more about your page and your business so they can display a richer snippet of your pages in search results.
Set the structured data with a list of structured data objects in the JSON-LD format as defined by schema.org.
Note:
You should always invoke the wixSeoFrontend.structuredData getter outside of the onReady() event handler to
ensure receiving the proper response.
This method doesn’t return any custom errors, but may return standard errors. Learn more about standard Wix errors.
