Domain Authority

developer
GET/v1/domain/authority

Calculates a composite authority score for a domain based on multiple signals including traffic rank, domain age, and web presence indicators.

What It Does

Aggregates authority signals from multiple data sources: Tranco traffic ranking data, WebsiteLaunches site authority, and domain age via RDAP. Combines these into a single composite authority score (0-100) that reflects the domain's overall strength and credibility.

Why It's Useful

Domain authority is a key metric for SEO, competitive analysis, and business evaluation. A single composite score makes it easy to compare domains, track authority growth, and evaluate web presence.
