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.
Related GoGuides AI Visibility & Trust Utilities
These GoGuides utilities work together: explain crawler activity, inspect AI visibility gaps, compare robots.txt with trust-layer signals, check verified text records, and activate a public Trust Signal when a domain is ready.
