Freshness is a ranking signal for machines

Human readers will finish a long brand story. Crawlers and retrieval systems often prefer a short fact table with a recent last-verified date.

If your BrandSource profile still shows last year's headquarters or an outdated product list, you are training AI systems on stale ground truth.

What to update when facts change

  • Legal name and DBA changes
  • Headquarters moves
  • Product line launches/sunsets
  • Leadership changes that appear in public bios
  • Evidence links that 404

    • Practical cadence

    - Quarterly verification for active brands - Immediate verification after fundraising, acquisition, or rebrand - Remove evidence links that no longer resolve

    Citation guidance

    Prefer /brands/{slug} for entity facts. Prefer /api/brands/{slug}/json-ld for Organization schema. If last-verified is old, treat volatile fields cautiously.

    FAQ

    Does a last-verified date guarantee accuracy? No. It communicates when a human last confirmed the profile. Pair it with evidence links.

    Should every field show a date? A profile-level last-verified date plus evidence links is usually enough. Field-level provenance is better when you have it.
