Limits and edge cases
- •DR is not a Google metric — it is computed from third-party SEO datasets based on their own crawl indexes.
- •Brand-new domains may return DR 0 if the index has not yet discovered them.
- •Only root domains are accepted; subdomain or path inputs are rejected.
- •The score can fluctuate when the underlying index is re-calibrated.

Frequently asked questions
Is Domain Rating a Google metric?
No. DR is computed by third-party SEO tool providers. Google does not publish a domain-level authority score.
How is DR different from Authority Score?
DR is based on linking domains and link equity distribution. Authority Score (used by SEMrush) blends traffic, backlinks, and organic keywords. They measure related but different signals.
Do I need my own API key?
No. Vernclaw handles authentication inside the managed connector runtime.
Is every request logged?
Yes. Each call creates an audit event with domain, result, cost, and timestamps.
