A: Hi Sumo-ling,

Yes, uSchema is compatible with all themes and plugins that follow Standard WordPress coding practices.

RankMath and uSchema both plugins use their own techniques to add schema. You may use both to create different schemas. For instance, you may use RankMath to add organization schema and simultaneously use uSchema to create more advanced schema that RankMath does not offer to add for your CPTs.

To get the content of the Post/Page, uSchema pluign uses standard WordPress 'the_content' filter. So, if a pluign is using this standard whether its Zion / Oxygen / Elementor or Blocksy, uSchema will work perfectly.

You can always spin-up a test install at https://test.uschema.io/
Blocksy, Zion Builder and Rankmath are installed on the test environment to check compatibility as you like.

Hope this test install will help you try the plugin along with your desired theme/plugins.

Cheers,
