How to correctly apply article and video schema for improved SERPs?

Hello, we recently hired a company to check over our SERP and Core Vitals and they came back with a few suggestions that I was hoping the Shopify Community could help us with.

The issue:

  1. Ensure article schema and video schema have the correct fields.
  2. Add video schema markup to pages with Youtube videos to improve chances of ranking for Videos on the SERPs

The Suggestion:

  1. Dynamically pull in each blog’s URL under the URL field in the article schema
  2. Add video schema code to each page with videos.

They sent us over 2 documents that appear to have a bunch of schema code.

My question for you is, where does this go?
