PR003 – Taxonomy Validation

Overview

Assessment for taxonomy validation. Checks that product category/taxonomy is consistent and valid across schema, breadcrumbs, and page.

Probability that AI systems use this signal: Crawlers and generative AI pipelines consume structured and visible page signals for training and inference. Assessment-specific signals (e.g. schema, canonicals, trust cues) affect how likely a page is indexed and surfaced. The probability that this assessment's signal influences AI behavior is high when the page is in a product or compliance context.

Impact on geo compliance: Passing this assessment supports geo compliance by ensuring machine-readable and visible content meet standards that reduce the risk of wrong locale, pricing, or trust in AI-generated answers. Failing can lead to non-compliant or misleading surfacing.

What We Check

  • Taxonomy extraction and validation: category/category path consistency across schema, breadcrumbs, and page content; valid category codes or paths.
  • schema.org Product category can be Text, URL, or CategoryCode; align with breadcrumb list and visible category labels for clarity and SEO.
  • Full logic in backend: pr003_taxonomy_validation (product_relationships).

Additional Resources

  • schema.org Product category — A category for the item; greater-than or slashes can indicate hierarchy. Keep category values consistent with breadcrumbs and site taxonomy.
  • Site taxonomy best practices: stable category IDs/paths, consistent naming across locale variants; helps SH008 (category tagging) and discovery.
