How to install the markup
Copy the generated script tag and place it in the <head> of the relevant page — the homepage for the main business entity. On WordPress, use your SEO plugin’s custom-schema slot or a header snippet plugin rather than pasting into theme files. Install it once: duplicate business markup from multiple plugins is a common mess this generator cannot fix.
Then validate: run the page through the Schema.org validator (syntax) and Google’s Rich Results Test (feature eligibility). Both are free and take under a minute.
