When implementing Rich Pins, what is the immediate action required after adding schema markup to your website to ensure correct functionality on Pinterest?

The immediate action required after adding schema markup to your website when implementing Rich Pins is to validate the Rich Pins using Pinterest's Rich Pin Validator. The Rich Pin Validator is a tool provided by Pinterest that checks if the schema markup on your website is correctly implemented and if Pinterest can properly extract the relevant data. Submitting a URL to the validator allows Pinterest to crawl the page and verify the presence and accuracy of the markup. This validation step is essential to ensure that Pinterest can correctly display Rich Pin information like product prices, article authors, or recipe details. If the validation is successful, Pinterest will enable Rich Pins for your domain. If errors are found, the validator will provide specific feedback on what needs to be corrected in the schema markup before Rich Pins can be activated.
