Google Search Central — "We won't show a rich result for time-sensitive content that is no longer relevant"; data freshness is implicitly rewarded

Claim: Google's structured-data guidelines: "Provide up-to-date information. We won't show a rich result for time-sensitive content that is no longer relevant."

Confidence: Verified — primary.

Why this matters for Candid: Supports the "change frequency" leg of R1 — Build a searchable, structured catalogue when records are numerous, change often, or carry several independent queryable attributes. Frequently-changing data benefits from a structured/automated source of truth rather than a hand-edited document — the alternative is silent ineligibility for rich results once the content goes stale. Bridges into the cms-workflow / maintenance burden topic.
