Domain Age And Authority Signal Extraction

Unique: Integrates domain age, authority metrics, and historical WHOIS data as explicit valuation inputs rather than treating them as secondary factors, enabling detection of domain quality issues (spam history, frequent transfers) that affect valuation

vs others: More comprehensive than simple domain age checks; integrates multiple authority signals (DA, DR, TF) rather than relying on a single metric; less detailed than professional domain appraisals which include manual reputation assessment
