# Check Domain Age

Domain age is a widely used trust signal across the internet. Search engines, email providers, and security tools all factor domain age into their assessments. A domain registered yesterday that sends bulk email gets flagged as spam. A domain with 15 years of continuous registration carries inherent authority. For SEO, older domains tend to have stronger backlink profiles and established authority.

The lookup_domain skill retrieves the original creation date for any domain, letting you calculate its exact age. This is valuable for SEO analysis (assessing domain authority potential), security evaluation (new domains are more suspicious), domain investment (age adds value), and competitive research (understanding how long competitors have been established). A simple data point that informs decisions across multiple contexts.
