👍 thanks

@slorber just found out, we can annotate existent HTML markup to following BlogPosting schema, then we won't need to use JSON-LD. What do you think of this? https://orbitingweb.com/blog/schema-org-microdata-guide/

[slorber]

This might make the structured data more maintainable and avoid using duplicate conditional logic?

Not sure we have this case on the blog posts, but how does it work when 2 structured data entities markup get interleaved in the HTML markup?

Does it lead to the exact same SEO outcome?

That's worth attempting a refactor

@johnnyreilly any opinion?

There shouldn't be a problem with this, since there is microdata for blog lists.

Yes, and moreover we get rid of duplicated data in separated comp. I'll see to this, maybe it will work out.
