About bulk domain age checking
When you are vetting expired domains to buy, screening guest-post prospects or reviewing link partners, age is one of the first filters: a genuinely aged domain carries a public history that a domain registered last month simply does not have. Doing that one domain at a time for a list of fifty prospects is painful — this tool runs the whole list for you.
Each lookup reads the official public registry (RDAP, the modern successor to WHOIS), so the registration and expiry dates are the real ones on record. We check domains sequentially with a short delay between requests, which is polite to the registry and keeps every lookup reliable. The service is free and unlimited — run as many batches as you like.
FAQs
How many domains can I check at once?
Up to 10 domains per batch — free, and you can run as many batches as you like. Paste one domain per line; if you paste more than 10, only the first 10 are checked. Need hundreds at once? Unlock Pro with a Pro key.
Is the bulk domain age checker free?
Yes, completely free with no sign-up, and you can run as many batches as you like. The lookups go to the official registry (RDAP) in real time, one at a time, with a short pause between requests so we never hammer the registry.
Where does the bulk data come from?
From RDAP, the official public domain registry protocol that replaced WHOIS. We read each domain's real registration and expiry events directly from the registry, so the dates shown are the ones officially on record.
Why do SEOs check domain age in bulk?
Link builders and SEOs vet dozens of domains at once — expired domains to buy, guest-post prospects, or potential link partners. Checking a whole list in one go shows which domains are genuinely aged and which are brand new, in seconds instead of one by one.
