About

Domain age is a fundamental signal in search engine algorithms, representing the length of time a domain has been registered and active. Search engines like Google utilize this metric as a proxy for trustworthiness and stability. Newly registered domains are often subjected to the Sandbox Effect, a probationary period where ranking potential is artificially suppressed to combat spam. Conversely, aged domains benefit from accumulated Trust Flow and are statistically less likely to be used for ephemeral malicious activities.

This tool bypasses the limitations of browser-based Whois lookups by leveraging the RDAP (Registration Data Access Protocol). It parses raw endpoints, normalizes inconsistent TLD data structures, and computes the exact chronological lifespan in years, months, and days. It is essential for domain investors evaluating backorder targets and SEO specialists auditing backlink profiles.

Formulas

The domain age A is calculated as the precise temporal distance between the Registration Date t_reg and the Current Date t_now. The Trust Score S is a non-linear function of age.

{

A = t_now - t_regS = min(100, log(A) × k)

Where k is a coefficient adjusted for industry volatility. Expiration proximity is visualized as:

t_now - t_regt_exp - t_reg

Reference Data

Domain Age Tier	SEO Classification	Trust Impact	Risk Profile
0 - 6 Months	The Sandbox	LOW	High volatility; frequent fluctuations in SERP.
6 - 12 Months	Probationary	MODERATE	Stability improves; eligibility for competitive keywords begins.
1 - 5 Years	Established	HIGH	Full ranking potential unlocked; "brand" signals recognized.
5+ Years	Authority	VERY HIGH	Legacy advantage; resistant to minor algorithm shifts.
10+ Years	Legendary	MAXIMUM	Top-tier trust signal; often correlates with premium valuations.

Frequently Asked Questions

Registrars sometimes display the "Updated Date" as the creation date if the domain was transferred. This tool queries the RDAP "registration" event specifically, but data depends on the TLD registry's transparency.

No. While age is a trust signal, it is one of hundreds. A 10-year-old domain with toxic backlinks or poor content will still fail. Age acts as a multiplier for good practices, not a substitute.

RDAP (Registration Data Access Protocol) is the modern successor to WHOIS. It provides structured JSON data instead of unstructured text, allowing for more reliable parsing of dates and statuses.

If a domain is fully expired and deleted, it returns a 404 (Available). If it is in the "Redemption Period" or "Grace Period", the original creation date usually persists until deletion.
