Domain Authority Calculator

The Domain Authority Calculator estimates a proxy score using four input signals: backlinks, referring domains, domain age, and on-page quality. It targets SEO managers, agencies, and site owners seeking a quick baseline for comparison. The tool is designed for repeatable assessments across multiple domains and campaigns, aiding planning and prioritization.

Conceptually, it combines normalized signals into a single score with transparent weighting so users can understand which inputs drive the result. A breakdown shows each component's contribution, enabling targeted optimization efforts. Results can be exported for reporting or archival purposes, and the scoring model can be adjusted in advanced mode to reflect evolving benchmarks.

Use cases include pre-campaign benchmarking, partner evaluation, competitor analysis, and progress tracking over time. Distinctive value lies in providing a transparent, reproducible proxy score without relying on proprietary data sources, making it accessible for in-house teams and smaller agencies. Core features include data input fields for backlinks, referring domains, domain age, and on-page quality, with optional weighting presets and export options. The tool emphasizes explainability, enabling users to trace the score to its contributing signals and to compare domains on a like-for-like basis.
