I am unclear how the integration with Rankmath works, I enabled the Settings but there is nothing in the drop down as seen on other posts in this forum.
1 – Enable the RankMath Pro integration in the Site Reviews settings.
2 – Enable the schema option in the “Latest Reviews” Elementor widget settings.
When you do this, Site Reviews will automatically add the rating schema of your reviews to the existing RankMath Schema Markup that you have added to your page.
I added additional values to the schema but they do not show when testing the page. I enabled rankmath support but nothing shows after clearing cache when using the testing tool local business shows twice, looking at the raw html LocalBusines shows twice there is something not set up properly its driving me crazy.
It sounds like you haven’t yet configured the RankMath Pro plugin for your website.
When the RankMath Pro schema integration is enabled in the Site Reviews settings, you will not be able to set any schema properties in the Site Reviews settings, or use the Site Reviews schema filter hooks. Instead, you will need to manage your schema markup and settings with the RankMath Pro plugin!
