Public signal checker

Website History Checker

This checker adds archive context to a technical report by showing whether public web archives have seen the domain before.

The check uses public live signals and does not make a security, malware, fraud or legal verdict.

Run a public signal check

  • HTTP
  • DNS
  • TLS
  • RDAP
  • Archive

Paths, query strings and fragments are removed before analysis. Only public http and https hosts are accepted.

What this checker analyzes

  • First known Wayback CDX timestamp where available.
  • Last known Wayback CDX timestamp where available.
  • Comparison with the domain registration date when RDAP exposes it.

Why it matters

  • Archive history can help explain redesigns, inactive periods and ownership changes.
  • It is useful context for agencies taking over unfamiliar domains.

What the results mean

  • First archive signal means a public archive has a trace for the domain around that date.
  • Last archive signal shows recent archive visibility, not current site quality.
  • Unavailable means no usable archive response was returned.

Limits of this check

  • Archives are incomplete and may exclude blocked, removed or uncrawled pages.
  • Archive timestamps are not proof of ownership or legality.
  • SiteTraceKit does not store its own history.
What should also be reviewed manually?

Review notable values in the context of the actual website, its subpages and connected services. A homepage check cannot prove the complete configuration, legal position or security posture.

FAQ

Why can archive history be missing for an active website?

Archives may not have crawled it, may be blocked, or may not expose data for that domain.
