Computed from: matched URL + rank + last crawled + algorithm version. This identifies the GoGuides trust record state; it is not domain-owner verification.

Provenance Observation History

This timeline shows when GoGuides recorded this trust state, including rank, crawl timing, algorithm version, and verification fingerprint.

Trust Favicon Previews

These favicons are generated directly from GoGuides trust measurements for the site. They are not decorative — the design is derived from the same data used to evaluate the domain (AI Rank and crawl timing). Because the favicon is generated from these measurements, the same inputs always produce the same trust favicon. Each favicon is therefore unique to the website it represents. If the favicon ever appears different elsewhere, verify the record here to confirm the current measured state.
