Re: schema.org and DIVI sites

Divi 3.0 uses React and unfortunately, their plugins are not open source.
(that sucks)

My suggestion is to reach out to Divi customer support and demand that they
add Schema.org support for their 30+ Elements and 40+ Content modules, at a
minimum.

An good alternative is mentioned here by our resident Jarno:

But all depends on what you are trying to accomplish or tell the world
about the data that is contained on your site by giving it structure
through Schema.org

Take a cruising look through the Semantic Search Marketing posts
specifically about Wordpress:

(and I would encourage you to join Semantic Search Marketing as well, where
you will find helpful folks within its great community)

Best,
