How it works
Paste any source URL and check the trust signals the source actually carries. The tool scores the domain tier, HTTPS, author byline, date, external citations and freshness. The composite score is the rough probability that an AI assistant will lift content from this URL.
Why domain tier is 50% of the score
- Tier 1 domains (major news, research institutions, .gov, .edu) are treated as near-ground-truth by every major assistant.
- Tier 3 domains (Medium, Substack, Reddit) can still be cited, but only when paired with strong internal signals: named authors, dates, external sources.
- Unknown domains default to a middle score - this is where ambitious brands can punch above their weight by nailing every other signal.
Pair with
For content on a low-tier domain, load up on the other trust signals: use the Trust Signal Analyzer to audit your content, the Citation Builder for inline references, and the Article schema generator for machine-readable author and date metadata.
