How to find expired domains with great backlinks

Backlinks are the one thing on an expired domain that genuinely transfers. The content is gone, the rankings go with it, the traffic was going to pages that no longer resolve. But a link on somebody else's site still points at this domain the morning you take it over, and it keeps pointing there until an editor removes it.

That's the whole reason this market exists. It's also why the filtering matters so much, because "has backlinks" is nearly meaningless on its own. A domain with 40,000 backlinks can be worth less than one with 300. This guide covers how to read a link profile properly, the ratio that separates a real profile from link spam, how to check the links are still alive, and what Google's current policies mean for the plan you have in mind.

Read the ratio, not the total

The first number everyone looks at is total backlinks. It's the least useful one on the page.

What matters is how many distinct domains those links come from. One site that puts your link in its footer across 12,000 pages generates 12,000 backlinks from a single referring domain. That's one editorial decision, from one webmaster, and search engines have discounted sitewide footer links for the better part of two decades. Three hundred links from 280 different domains usually means a lot of independent decisions rather than one. Not always, because a single owner or network can sit behind dozens of domains, which is why the next step is always to open the links. But the second profile is worth far more, and it will show a smaller headline number.

So the ratio to compute is referring domains divided by total backlinks, and you want it high, not low:

The ratio is a sorting tool, not a verdict. A spam network can hand you one link from each of two hundred domains, and a legitimate site can end up with a low ratio from syndication or a navigation template. What the ratio does reliably is tell you which profiles are worth ten minutes of opening pages. It's also worth being precise about, because the advice circulating on this topic has it upside down. You'll read that you should cap referring domains at around ten percent of the backlink count to screen out spam. That rule would reject the best profile in the table above and wave through the worst. Count the sources, and prefer more of them.

Relevance beats authority, and it isn't close

A Trust Flow of 40 on a domain whose links all come from Italian furniture blogs is worth very little to your fitness site. A Trust Flow of 18 where every link comes from cycling and outdoor retail is worth a great deal if you're building in that space.

Majestic's Topical Trust Flow is the fastest way to read this, because it tells you what subject the link profile sits in rather than how strong it is in the abstract. We surface it as a category on every enriched domain, so you can filter for the ones whose links come from your own subject area instead of sorting by raw authority and hoping.

Language is part of the same question and it's easier to get wrong. A domain with excellent metrics built entirely on Russian or Indonesian links is a specific asset for a specific market. If that isn't your market, those links won't do what you want, and the domain is cheap for a reason.

Four checks on the links themselves

Metrics are a filter. They tell you which twenty domains out of ten thousand deserve your attention. Then you open the links, because every metric on the page was computed from a crawl that happened in the past.

Are the linking pages still live?

Take the strongest fifteen or twenty referring pages and open them. A link counted in a database six months ago may sit on a page that's since been deleted, rewritten, or taken down with the whole site. This single check removes more bad buys than any threshold, and it's the one most people skip because it takes ten minutes rather than one click.

Where on the page does the link sit?

In the body of an article, surrounded by relevant text, is the real thing. In a footer, a sidebar blogroll, an author bio repeated across a site, or a comment, it's worth a fraction of that. A sidebar carrying a hundred outbound links is a link directory, whatever the site's metrics say.

What does the anchor text look like?

Natural profiles are messy. Expect the brand name, the bare URL, "click here", the page title, and a scatter of partial phrases. When a profile is dominated by commercial exact-match anchors, especially in a different language or a different vertical from the site itself, somebody was buying links. That history is attached to the domain and it's the clearest signal to walk away.

Do the prestige links do what you think?

This is where expectations need managing. External links on Wikipedia have carried rel="nofollow" since 2007. Developer and startup platforms commonly apply nofollow or user-generated-content attributes to outbound links too, though it varies by platform and by where on the page the link sits, so view the source of the actual linking page rather than assuming. Many newsrooms do the same.

That doesn't make them worthless, it changes what they're good for. A citation on Wikipedia or a mention in a real article is context about what the domain was, a referral audience that still clicks, and often a trail of secondary links from people who found the site through it. Just don't buy one expecting it to pass authority the way a plain link would, and do read the linking page before you bid. A domain cited in a genuine article about the old brand and a domain linked from a user-generated listing look identical in the metrics and are not the same purchase.

How to filter for this on CatchDoms

Across 22 sources we carry referring domains and total backlinks, Trust Flow and Citation Flow, the Majestic topical category, and the archived screenshot. The combination that works is a floor on referring domains plus a floor on Trust Flow, then the spam filter on top.

Those are the three parameters worth starting from: rd_min=50 for a profile built from real breadth, tf_min=15 for link quality, hide_spammy=1 to drop the obvious junk. From there, narrow by subject with the category filter, and add cf_min only if you want volume as well as trust. If your niche is narrow, drop rd_min to 20 before you drop tf_min, because breadth is easier to compromise on than quality.

We also break out the three link sources people specifically hunt for, since they're invisible in an aggregate count: domains with a sampled link from Wikipedia, from a major news outlet, and from GitHub, Hacker News or similar. Each page shows the linking page and the anchor so you can read it before bidding rather than after.

What Google's policies actually say

Two policies apply, and neither says what the nervous version of the internet claims.

In March 2024 Google added expired domain abuse to its spam policies, defined as the case where "an expired domain name is purchased and repurposed primarily to manipulate search rankings by hosting content that provides little to no value to users." The examples are all mismatches: affiliate content on a former government agency domain, commercial medical products on a former medical charity, casino content on a former elementary school.

Separately, the link spam policy covers buying and selling links for ranking purposes.

What follows from both: acquiring a domain because people link to it is not the problem. The problem is acquiring it for its residual reputation and then putting something thin and unrelated on it. A useful habit is to check it from the reader's side. Someone clicks a ten-year-old link expecting the site they remember. Do they land on something that serves them, in roughly the subject area they were expecting? If they land on an unrelated commercial offer, you've built the exact example in Google's documentation. Passing that check isn't a guarantee, because the policy is about the purpose of the whole exercise rather than topical overlap alone, but failing it is a reliable way to end up in scope.

Which has a practical consequence for how you filter. The relevance check isn't a nice-to-have for SEO efficiency. It's also the part of the risk you get to control.

Links decay, so move fast

From the day a site goes down, its links start disappearing. Editors clean up dead links, plugins flag 404s, sites get redesigned and the old resource page vanishes, and whole domains in the profile expire themselves. The decline isn't dramatic in any one month and it compounds.

Two things follow. First, metrics computed before the site died overstate what's there now, which is why opening the linking pages matters. Second, the sooner the domain serves relevant content again, the more you keep. A domain pointed at a holding page for eight months loses links that a domain live in week one would have kept.

What to pay

Auction domains with visible link metrics start around $100 and go up with the bidder count, because everyone is reading the same numbers. Dropped domains cost registration, and the strong ones get taken quickly.

The mispriced domains are the ones whose value isn't in the headline metrics. A moderate Trust Flow with tightly relevant links in a specific industry gets passed over by buyers sorting on authority. A profile whose strength is a handful of genuinely editorial links shows a modest total. Those are the ones worth the ten minutes of opening linking pages, because the metric-sorters never see them.

Before you bid

• Referring domains are a healthy share of total backlinks, not a rounding error
• The strongest linking pages are live and still carry the link in the body
• Anchor text looks messy and brand-led rather than commercial and repetitive
• The topical category and the link languages match the market you want
• The archived screenshot shows a real site, not a doorway or a parking page
• Your plan for the domain fits its history closely enough to pass the reader test
• The name itself is clear of trademarks, per the trademark checklist

FAQ

How many referring domains should I look for?

There's no universal floor, because 30 tightly relevant referring domains can beat 500 unrelated ones. As a starting filter, 50 referring domains with a Trust Flow of 15 or more produces a workable list in most niches. Loosen the referring domains before you loosen the quality threshold.

Can I trust Trust Flow, Citation Flow and Domain Authority?

They're third-party estimates from different crawls, so they disagree with each other and none of them is a Google ranking factor. They're good at ordering ten thousand domains so you know which twenty to inspect. They're not evidence about any individual domain, which is what opening the linking pages is for.

Is one strong backlink better than a hundred weak ones?

Usually, if it's relevant and editorial. But a single link is fragile: one deleted page and the profile is gone. A domain whose value rests on one link is a riskier purchase than the metrics suggest, so check that link personally and factor the risk into what you bid.

Do the backlinks transfer when I buy the domain?

The links keep pointing at the domain, yes. Nothing else transfers, not the content, the rankings, or any relationship with the linking sites. Whether the links keep their value depends on what you put there and how quickly.

Are nofollow links worth anything on an expired domain?

They're worth something different from what people expect. A nofollow citation on Wikipedia or in a real news article gives you referral clicks, context about what the domain was, and a basis for the secondary links that tend to follow. Treat them as audience and provenance rather than a ranking transfer.

How do I know the links won't vanish next month?

Check how long each link has existed and how healthy the linking site looks. A link that's survived five years on a site that still publishes is a good bet. A link from 2013 on a site that hasn't updated since 2016 is one redesign away from gone.

Do Google penalties carry over to the new owner?

Manual actions attach to the site and can persist through a change of ownership, so check Search Console for manual actions as soon as you take over. A domain whose archive shows obvious spam, cloaking or hacked pages is carrying risk you can't fully measure from outside, which is what the spam filter and the archived screenshot are for.

The short version

Count referring domains rather than backlinks, insist the links come from your subject and your language, and open the strongest fifteen linking pages before you bid. Then build something on the domain that the people clicking those old links would actually want. That last step is both the SEO strategy and the compliance strategy, which is convenient, because it means there's only one thing to get right.
