Frequently asked questions
Why does domain age matter for SEO?
Older, established domains often correlate with higher trust and authority, since they've had more time to build backlinks and content history - though age alone isn't a direct Google ranking factor, it's a useful signal when researching a domain.
Is a newer domain automatically at a disadvantage?
Not necessarily - a well-optimized new domain with quality content and backlinks can still rank well. Age is one signal among many, not a hard requirement.
Where does the domain age data come from?
It's calculated from the domain's original WHOIS registration date, which is publicly available registration data.
