How to generate useful schema markup without making SEO promises
Choose the type that describes the main visible content, then enter only facts a visitor can verify on the page. Siftlet emits JSON-LD because Google recommends it as the easiest structured-data format to maintain.
The local receipt checks JSON syntax, the selected template's required fields, absolute URLs, numbers, breadcrumb items, and a few format-specific values. It does not replace Google's Rich Results Test or the Schema.org validator, and valid markup does not guarantee a rich result.
Paste the script into the page HTML, normally in the head or body. Keep dates, price, availability, address, ratings, and other changing values synchronized with the visible page. Never add fake reviews or facts that exist only in the markup.
