How to check a domain's history before you register it

A released domain is new to you, but not to the internet. Five free checks and about ten minutes tell you whether it comes with baggage.

1. See what the site used to be

Open the Internet Archive’s Wayback Machine and type in the domain. A calendar shows every day it saved a copy of the site; open a few from different years.

A real business, a blog, a project: a good sign.
A parked page or “this domain is for sale”: harmless.
Adult content, gambling, pills, fake designer goods, pages of gibberish, or a language you did not expect: a warning. The name may carry a bad reputation with search engines and email providers.

Our name pages show the years the Internet Archive recorded a live site, so you can see at a glance which names had one.

2. Check it is not flagged as dangerous

Put the domain into Google’s Safe Browsing site status. It shows whether Google currently flags the site as unsafe — malware, phishing and the like, the warnings browsers show before letting anyone in.

3. Check its email reputation

If you will send email from the name, look it up in Spamhaus’s domain reputation checker. The Spamhaus Domain Blocklist is a list of domains with a poor reputation, and many mail systems use it. A listing expires by itself once a domain stops matching what caused it, and removal requests are free — anyone charging to remove a listing is running a scam.

4. Search for it

Search the name in quotes. Reviews, complaints, news stories and old social accounts tell you what people remember it for.

5. Make sure it is not someone’s trademark

Search the name in the USPTO’s free trademark search (and the trademark office of any country you will sell in). A released name is anyone’s to register, but one that matches another business’s brand can be taken from you under ICANN’s dispute policy if it was registered and is used in bad faith — and is a poor foundation for a brand either way.

What a bad history means

An old parked page means nothing. A Spamhaus listing usually fades. Recent malware or phishing, heavy spam, or a trademark problem are reasons to pick another name — there are about 100,000 more released every day.
