Domain Age & History Checker

Registration · First Seen Online · Live Status

Find out when any domain was first registered, when it was first spotted live on the web, and whether it's reachable right now — all in one free lookup.

Enter any domain (example.com) or URL — www and path are stripped automatically.

What You Get in One Lookup

Most domain age tools only show the registration date. We cross-reference multiple independent sources to build a complete picture: when the domain was registered, when it first appeared on the live web, and whether it's reachable right now.

📅

Registration Date

We query the official domain registry (like Verisign for .com or Nominet for .uk) to get the exact date the domain was registered, when it expires, who the registrar is, and any status flags like transfer locks.

🕸

First Spotted Online

The Wayback Machine (Internet Archive) has been crawling the web since the late 1990s. We find the earliest saved snapshot of your domain — the best available proof that the website was live on a given date. If Wayback has no record, we also check Common Crawl as a fallback.

🌐

Live Website Check

We make a live request to the domain right now, following any redirects, and report back the final status — whether it's up and loading, returning an error, or not responding at all. Response time per step is included.

When to Use Domain Age Data

🔄 Expired domain research

Before buying an expired domain, verify its registration history, check the Wayback Machine for previous content, and confirm it's not pointing to spam or thin affiliate sites.

🔍 Competitor intelligence

See when a competitor first registered their domain and when they first appeared in search (via Wayback). Understand how much of their authority comes from domain age vs. content.

🛡️ Trust assessment

New domains (< 6 months) purchasing paid traffic, offering services, or requesting backlinks deserve extra scrutiny. A fresh domain with aggressive claims is a common fraud signal.

🔗 Link building vetting

When evaluating a site for a guest post or link exchange, check its domain age. Very new domains with high traffic claims or inflated metrics are often PBN sites or content farms.

📋 Technical SEO audits

Confirm a client's domain registration is current and not expiring in the next 90 days. Check that name servers match the expected hosting provider. Verify no unexpected status flags.

🧪 Brand protection monitoring

Check whether a typosquat or brand-impersonating domain was registered recently. A fresh registration combined with a redirect to your domain is a brand abuse signal.

Frequently Asked Questions

What is domain age and why does it matter for SEO?

Domain age is the time elapsed since a domain was first registered. It's often cited as a trust signal — older domains with consistent history tend to have more established backlinks, content, and crawl history. However, Google has confirmed domain age alone is not a direct ranking factor. What matters more is how long the domain has had quality content and backlinks. Domain age is most useful when evaluating expired domains for purchase or assessing a competitor's history.

Where does the registration date come from?

We query the official domain registries directly — the same authoritative databases that WHOIS pulls from, just via a more structured, modern interface. For example, .com domains go through Verisign's registry, .uk domains go through Nominet. This covers virtually every TLD worldwide. Some privacy-protected domains and a handful of country-code extensions don't publish registration details publicly, so those may return no data.

What is the 'first spotted online' date?

This is the earliest date the Wayback Machine (Internet Archive) or Common Crawl saved a snapshot of the domain. It's not the same as when the domain first went live — web crawlers don't visit every site immediately after launch, especially smaller ones. The first snapshot can lag months or even years behind the actual launch date. Think of it as 'was definitely live by this date' rather than 'launched on this date.' If Wayback has no record, we also check Common Crawl, an independent web archive, as a fallback.

What do the domain status flags mean?

Status flags are set by registrars and registries to control what can be done with a domain. The most common ones: clientTransferProhibited means it's locked so it can't be moved to another registrar (standard practice for active domains); clientDeleteProhibited means accidental deletion is blocked; redemptionPeriod means the domain has expired and is in a grace period before permanent deletion — this is a warning sign if you're considering buying it.

Why is the registration date different from what WHOIS shows?

Both tools pull from the same official registry data, so they should match. Differences usually mean one of three things: the domain was deleted and re-registered at some point (the date reflects the most recent registration, not the original); the registrar migrated their systems and timestamps got shifted; or the domain uses a country-code extension that stores dates in a non-standard format. If dates differ significantly, check the registry's own WHOIS portal directly as the authoritative source.
