An expired domain is a name somebody let go, with the links and the history the old site earned. That is the whole asset. What you do with it decides whether those links are worth anything.
Here are the four things DomCop members build, in the order we see them, and where each one goes wrong.
1. A private blog network
A PBN is a set of sites you own that link to the site you want to rank. It is still the most common use of expired domains.
It works when two things hold. The domains are relevant to the site they link to, and each site looks like a real site to a human reviewer. It fails on footprints: the same host, the same theme, the same analytics account, the same registrar, sites that link to one money site and nothing else.
Where it goes wrong: treating it as a one-off purchase. A network is a running cost. Hosting, content, renewals and your time, every year. Plan it before you buy the first name.
Our three guides cover the parts: planning the network, choosing the domains and hosting without a footprint. Read the risks of PBNs first. If you do not want to run sites, this is not your route.
2. A 301 redirect
Buy an expired domain in your niche and redirect it to your site. Some of its link value passes to the page it points at. No site to build, no content to write, a few dollars a year.
It works when the old site was about the same thing as yours, and the links to it came from real sites. A redirected domain about cycling helps a cycling shop. It does nothing for a law firm.
Where it goes wrong: redirecting a domain with a spam history. The penalty passes as readily as the links. Check the Wayback history and the spam score before you point anything at your main site. If in doubt, redirect to a page you can afford to lose.
3. A new site on an aged name
Build your next site on a domain that already has links, age and a clean history, instead of a fresh registration. Search engines treat it as a known site from day one. Members tell us such sites rank months sooner.
It works when the old content and the new content are in the same field, and when you keep the old URLs alive. Rebuild the pages the links point at, or redirect them to the closest new page.
Where it goes wrong: a name whose past has nothing to do with the new site. A domain that was a flower shop for ten years does not become a software site by changing the content. The links keep pointing at flowers, and the engines notice the switch.
4. Names to resell
Short names, real words, brandable names and exact-match names for a product or a place. Bought at the drop for the registration fee, or at auction, and sold on to someone who needs that exact name.
It works when you buy names other people will want, not names you like. A name with a buyer is one a business would put on a sign.
Where it goes wrong: paying auction prices for a name only you like, and renewing it for years waiting for a buyer. Set a budget per name and a date to let it go.
What they have in common
- The metrics are a filter, not a verdict. DA, TF and the spam score cut a list of 3 million names to a few hundred. The decision comes from the history: what the site was, who linked to it, and why.
- Relevance beats strength. A DA 20 domain in your niche is worth more than a DA 40 domain in another, for every one of the four uses.
- Check availability the morning after. One in five good dropped names is taken within a day; the rest sit for weeks. Our study of 500,000 drops has the numbers.
Every name on DomCop carries the numbers for the filter and the history for the decision. The expiring list shows what is coming up, the dropped list what is free to register today.
