What gets checked?

Identity and matching

Property IDs, names, duplicate identifiers and fields used for platform matching.

Location and contact

Address, city, country, postcode, phone and coordinate quality checks.

Content and distribution

URL, image, description and target-specific required/recommended field coverage.

Compare one feed across platforms

We do not mix contract levels
Google Hotel Center, Wego and trivago checks use publicly documented requirements. Meta and Criteo checks are mapping/readiness pre-checks and are not presented as official platform certification.

Developer usage

Alongside browser validators, the same validation approach is exposed to AI agents over MCP and to local files, URLs, stdin and CI/CD through the @metasearch/feed-validator CLI/NPM package.
