What this checks
The format of Offer price and priceSpecification.price values, and AggregateOffer lowPrice and highPrice.
Why it matters
Schema.org asks for "." as the decimal separator and for the currency in priceCurrency, not in the price.
How to fix
Write prices such as 1299.00, without currency symbols or thousands separators.
Expected
A number, or a string of digits with an optional "." decimal part.
Applies to
Pages with at least one inspected Offer or AggregateOffer price value linked from a fully inspected Product.
Authority

Technical Score
Weight 2 of 3A price that is not machine-readable cannot be interpreted reliably.
How MaxiMarket detects it
Reports when an inspected price value (linked from a fully inspected Product) is neither a finite non-negative JSON number nor a string of digits with an optional "." and digits (surrounding whitespace ignored). Missing prices are STRUCTURED-OFFER-001 and -002.
