Methodology
How NPS Sounds Promotes A Place
NPS Sounds tracks National Park Service places through live signals, seasonal patterns, and sonified place-state.
Publish-tier governance
Every programmatic surface is governed before it is promoted to sitemaps or answer surfaces.
- FULL
- Indexable, sitemap-visible, internally promoted, source-provenance visible, answer brief present, quality score at least 75.
- SHELL
- Useful preview page with noindex, follow; excluded from Google-facing sitemaps until source-backed depth clears the FULL threshold.
- SUPPRESS
- Not public, broken, duplicate, or too thin to serve a reader or answer engine.
Answer extraction
FULL pages expose the same answer brief to humans, JSON-LD, markdown surfaces, and public answer APIs.
The answer brief names the best use, strongest months, peak crowd pressure, current signal status, visitor takeaway, and the sonified interpretation of the place. Structured data only describes claims visible on the page.
Source provenance
Source cards separate official identity, live operations, modeled weather and seasonality, and the NPS Sounds visibility model.
NPS Sounds is an independent Targeted Impressions project. It is not affiliated with, endorsed by, or operated by the National Park Service. Official alerts, closures, reservations, and safety guidance should be verified through nps.gov and other official public agencies.
