How your existing and duplicate structured data is treated by Google

By Ilana Davis

A customer asked about how JSON-LD for SEO works with old microdata, which is structured data most Shopify themes provide.

A question I had was about how the old Microdata is affected by installing your app. Does this live side by side with the new JSON-LD or get poofed?

JSON-LD for SEO only adds new structured data so you’ll have the existing microdata still there.

Google is okay with having duplicate sets of structured data on a page. They’ll end up using the most complete and error-free set they find (usually from my app).

This also means that you don’t need to clean up or remove any existing structured data that’s broken or incorrect.

You can just install JSON-LD for SEO and you’re good to go.
