Code is free now. Trust isn’t.
Stop launching your AI projects on dead-on-arrival domains.
You spend two weeks on a pretty name, then months waiting for Google to notice it. Meanwhile pragmatic builders pick up expired domains of closed projects at registration price, domains that real articles once linked to on the same topic. The extension strains a drop list in seconds, right on the page you are browsing: a verdict for every domain, the editorial sites that linked and what each one is about, and what lived on the domain last. No Ahrefs subscription needed.
Works on ExpiredDomains.net; the Auction plan adds GoDaddy Auctions, NameJet, DropCatch, SnapNames, Dynadot, Sedo and Namecheap Marketplace. Free to start; Pro costs less than one dead domain.
A brand-new domain
No signposts point here yet. Google waits to see whether you are real. Usually months before search sends anyone.
An expired domain with the right past
Years of links from newspapers, universities and real blogs, on one topic. Search already knows this corner. Often faster. Never guaranteed.
An expired domain with the wrong past
Foot traffic, but stolen goods were sold here: spam, casino, pills. Buy it and you inherit the watch too.
Plant many. Keep what grows.
Everyone has the same AI you have. Don't bet a month on one product and its name. Turn one idea into the narrow searches around it, plant a few small free tools, each on an expired domain whose past fits, and let the searches show which ones grow. Don't fall in love with your product.
Collect the long tail by hand: search suggestions, questions people ask, complaints in reviews. Group it by meaning and pick five different jobs a weekend tool can do completely.
Each tool goes on a domain whose old links point at the same kind of job, checked before you buy. It may get seen sooner than a brand-new name. Nobody can promise it.
Watch which searches bring people and who uses the tool. Feed what sprouts, stop feeding the rest, and walk away from a niche where nothing grows. Build real tools: mass-producing pages is spam.
Made for your first launches
Most expired-domain tools are made for professional domainers and link-network builders: they hunt live link power to pass on to another site. DD Backlink Strainer is made for people bringing their first AI-built products to market, and it looks for something else: a strong editorial core in the domain's past, on the topic you will build on. Reopened on that topic, a small free tool has a chance to be found sooner through narrow long-tail searches.
The method behind the tool is a book, free on this site: how to turn an idea into the searches around it, find each one a domain with the right past, plant, watch and kill fast.
A verdict for every domain on the list
Open ExpiredDomains or a domain auction and press Refresh. The side panel checks every domain on the page you are already browsing against a historical link graph of 470 million domains and sorts them, strongest first. No exports, no trips to the archive for every name.
- Strongseveral independent editorial sites linked to it
- Mixedsome real links, some reasons to look closer
- Weaknothing editorial, or a profile made of spam
Each line shows how many strong editorial sites linked, the share of spam, the earliest record and the drop years. Open a domain to see its top editorial donors with what each one is about, and what lived on the domain last, with a warning if it was a parking or spam page. One click copies a prompt with the data and a checking method for ChatGPT, Claude or Gemini. Pro adds the Donor X-Ray: all top 100 donors, and whether the editorial ones agree on one topic. Free plan: 250 domain checks a day.
New or expired: a fair comparison
The full guide| Brand-new domain | Expired domain, clean past | |
|---|---|---|
| First Google traffic | Usually months | Often sooner; no one can promise it |
| Price | Registration, often $10–20 a year | Often the same registration price for names nobody bid on; auctions run higher |
| The past | None. You start clean | All of it: links, drops, old content. Good or bad, it's yours |
| Trademark risk | Low if you invented the name; check anyway | Real: an old brand may still have an owner |
| Penalties | None | Possible, and only Search Console shows them, after you own the name |
| What to check | That the name is free to use | Who linked, the drop years, the archive, Safe Browsing |
Both routes are legitimate. A new domain costs time; an expired one costs a check. What doesn't work is buying an old domain to hang unrelated pages on its links: Google's spam policies call that expired domain abuse.
What a good expired domain looks like
Read the guideA clean past
No spam, pills or casino in the archive. A real site lived here.
The same topic
Its old links point at the subject you'll build on.
Real editorial links
Newspapers, universities, blogs that chose to link. Not directories, platform profiles or auto-generated pages.
A stable history
Dropped once or twice, not six times. Every drop is a chance the old trust reset.
A decent name
Something you can say out loud and build a product on. Not someone else's brand.
A sane price
Good drops often go for the registration price. Paying more is your choice.
Not every bad past is the same
A casino past usually washes out. Adult rarely does. There is no public list of punished domains, so the last check is cheap and direct: the $10 test. Buy the name at registration price, verify it in Search Console, read Manual actions, put one honest page back. If Google takes it, keep it. If not, you lost ten dollars, not six months.

Link observations since 2017 and public records of dropped domains for almost two decades. That shows a domain's past well. Two things it can't show, and nobody outside Google can: whether old links are still live, and whether a domain carries a manual penalty. Anyone who promises a "safe" expired domain is overselling.

Questions
Is an expired domain a shortcut to Google traffic?
It can be a head start, never a guarantee. Google may still treat the domain as new, and only Search Console shows a manual penalty, after you own the name. That is why the cheap last check is the $10 test.
Isn't building on an expired domain spam?
Not when you build the same kind of thing it was known for. Google's spam policies name expired domain abuse: buying an old domain to host unrelated or low-value pages and ride its old links.
Is this Ahrefs data?
No. Verdicts, donors and donor classes come from our own historical link graph (more than 470 million domains, observations since 2017) and public expired-domain records going back to 2006. Domain Rating by Ahrefs is shown only as a reference on a domain's page, through the free Ahrefs API.
Are the old links still live?
Not necessarily: the extension works with link history. Before you buy, check the shortlisted domains in the free Ahrefs backlink checker or in Majestic; the domain page has the buttons.
What does it cost?
The free plan checks 250 domains a day on ExpiredDomains, no card needed. Paid plans add more reports and domain auctions; see pricing.
