About schemaconflict
A free, open checker for value-level contradictions across the structured data on a page.
Google's Rich Results Test and the Schema.org validator check each block in isolation — and stay silent when two
valid blocks describe the same thing with different values. That is where the damage happens: a
product priced $19 in one block and $29 in another, two plugins each emitting an
Organization, an aggregateRating that disagrees between blocks.
schemaconflict parses every JSON-LD, Microdata and RDFa item, groups the ones that describe the same entity (by @id, GTIN/SKU/MPN, URL or name) and diffs their fields, mapping each contradiction to the Search Console or Merchant Center message it triggers. Paste mode runs in your browser; URL mode runs on Cloudflare and keeps no logs.
