Schema Markup Validator

Errors are problems that make the markup invalid for a rich result: a missing required property, a value in the wrong format, or a contradiction such as an end date before the start. Fix every error. Warnings point to recommended properties that are missing; the markup still works, but adding them, for example an image, dateModified or a price valid-until date, gives search engines more to show and can make the result more attractive.

The rules follow Google's structured data documentation for each type. Other consumers such as Bing, social networks and AI assistants read the same schema.org vocabulary, so clean markup helps everywhere.

The most frequent errors are dates written like 17/10/2026, prices such as ₹1,499 with a symbol and comma, image addresses starting with / instead of https://, ratings above five, availability written as In stock instead of https://schema.org/InStock, and plugins that output two conflicting Product blocks on the same page. Pasting the whole page source shows all blocks together, so duplicates and conflicting values from different plugins or themes are easy to spot and remove.
