Checking domain age for a whole list at once
Paste up to 20 domains, one per line, and this tool looks up each one's WHOIS registration date and age in a single batch - useful for comparing a list of expired or aged domains, auditing a portfolio, or screening candidates before a purchase. Each lookup takes a moment since it queries the domain's real WHOIS server directly, so larger batches take a little longer.
Why domain age matters when evaluating a purchase
An older, continuously-registered domain can carry an established history - prior backlinks, existing brand recognition, or an existing content footprint - that a freshly registered domain simply doesn't have yet. Domain age itself isn't a direct Google ranking factor, but the things that correlate with an aged domain (accumulated backlinks, existing trust signals) can be genuinely valuable when evaluating a potential acquisition.
Why checking many domains in bulk saves real time
Comparing a shortlist of candidate domains - whether for an expired-domain purchase, a portfolio audit, or screening brandable names - means running the same WHOIS lookup repeatedly. Batching the whole list at once means you only wait through one combined check instead of running each domain through a lookup individually and keeping track of results yourself.
What an error result usually means
A domain showing an error instead of an age typically means it isn't currently registered, uses a less common TLD with a non-standard WHOIS response format, or the registry simply didn't respond in time - re-checking that one domain individually often resolves ambiguous cases that a batch lookup couldn't fully process.
