Finding expired domains with backlinks that count is harder than finding domains with high link counts. Raw link numbers can be inflated by spam networks, sitewide links, and backlinks from low-authority sources that may count for very little. What matters is referring-domain quality: links from legitimate news sites, universities, and industry leaders carry weight. Understanding the difference lets you identify domains whose backlinks will actually benefit your site.
Referring-domain quality over link count
Most people look at one number: total backlinks. If a domain has 1,000 backlinks, they assume it is strong. In reality, suppose one domain has 500 backlinks from 50 reputable news sites and another has 1,000 backlinks from 30 sites, most of them spam or parked pages. The first is far more valuable.
A better guide than total link count is referring domains: the number of unique domains that link to a site. A link from a respected news site is worth more than many links from auto-generated spam sites.
In your backlink tool, look at the referring domains count, not the raw backlink count. Suppose a domain has 2,000 backlinks but only 80 referring domains: many of those links come from the same few sites or a network, and the profile is much weaker than the headline number suggests. This is why hunter.domains scores referring domains and not raw backlink counts alone.
Which links carry weight: news, universities, industry sites
Not all referring domains are equal. A link from a university, a government agency, an established news organization, an industry-leading publication or a recognized brand is generally a stronger sign than a link from a machine-generated site. Those sites are hard to get links from.
Links from parked pages, auto-generated directories and article spinners tend to be worth little. Links from "SEO blogs" with obviously copied content also signal low quality. When you look at the referring domains in your backlink tool, read the names. Do they look like real organizations? Or do they look like machines generated them?
A domain with 20 links from real news sites is stronger than a domain with 200 links from parking pages. Open the top referring domains in your backlink report and spot-check them: is each a real site or obvious spam?
Checking that the links are still live
Referring links can break if the pages they sit on are removed or the pages they point to go offline. When you find a domain with good referring domains, verify that those links are still live.
Take one of the top referring domains from your backlink tool and visit it. Click the link to see if it actually points to the expired domain you are evaluating. If the link is gone or broken, it will not help you, even if you buy the domain. This is not uncommon: many sites delete old pages or reorganize without maintaining redirects.
A practical approach: check the top referring domains one by one. If most of them still link to the domain and the links are live, the profile is solid. If only a few are still live, the backlinks have decayed more than the numbers suggested.
Filtering out sitewide links and link networks
Sitewide links are links from every page of a domain (usually in the header, footer, or sidebar). They boost link counts dramatically but can be worth less than editorial links because they are not content-earned. Suppose a domain has 500 backlinks but 400 come from sitewide links on 3 different networks: the real authority is much lower.
If your backlink tool lets you filter out sitewide links, do it and check the referring domain count again. Suppose the count drops from 150 to 80: that tells you many of the referring domains were sitewide links.
Link networks (also called PBNs, or private blog networks) are interconnected sites owned by the same person or company for the sole purpose of selling links. Links from PBNs are risky because they fall under Google's link spam policy: "Link spam is the practice of creating links to or from a site primarily for the purpose of manipulating search rankings." No tool catches every network, so check manually: if many referring domains are obviously low-quality, loosely related to your niche, and have similar layouts or publishing patterns, you are probably looking at a network.
If you spot signs of a link network, reduce your bid or pass on the domain. The risk is not worth it.
What the anchor-text spread tells you
Anchor text is the clickable text of a link. If all the backlinks to a domain use the same anchor text (like "weight loss supplements" repeated 400 times), it can look like deliberate manipulation.
Diverse anchor text is a better sign. You want to see a spread: some branded anchors (the domain name), some generic anchors ("click here," "learn more"), some keyword anchors, and many others. In your backlink tool, look at the anchor text report. If one anchor dominates the list, the profile looks unnatural. If the spread is wide, it looks more legitimate.
This is a quick smell test. You do not need exact percentages; just read the anchor-text list and ask yourself: does this look like it was built naturally or deliberately manipulated?
A worked search with filters
Here is how to find quality expired domains with real backlinks:
- Start with a list. Use hunter.domains and its advanced filters (a Pro feature) to filter domains by authority, referring domains and age. Pick thresholds that fit your project; for example, DR 40 or higher, 50 or more referring domains and five or more years of age. You now have a list of older, legitimate-looking domains.
- Open your backlink tool. Pull the backlink profile for your top candidate. Sort by referring domain (not backlinks) and scan the top ones. Are they legitimate?
- Exclude sitewide. If your tool can filter out sitewide links, do it. Does the referring domain count drop significantly? If it does, reassess.
- Check anchor text. Look at the top anchor text. Is it diverse or concentrated? Concentration is a red flag.
- Spot-check links. Visit several of the top referring sites and verify the links are still live. Broken links are normal, but if many are dead, the backlinks have decayed badly.
- Evaluate the niche fit. Do the referring domains make sense for your intended use? A domain with backlinks from tech blogs is valuable for a tech site, but less so if you plan to rebuild it for fitness content.
After this process, you have a clear picture of the backlink quality. A domain that passes all these checks is worth bidding on, and the step-by-step buying guide covers what comes next.
Keeping the links after purchase: same URL structure
Here is the critical part that many people miss: when you buy an expired domain and rebuild it, you need to maintain the same URL structure to keep the backlinks.
If the old domain was example.com/products/widget.html and you rebuild it as example.com/articles/new-article.html, the old backlinks point to a 404 page and are wasted.
To preserve the backlinks, keep the same URL paths. If the old domain was an e-commerce site with /products/, keep that structure. Set up 301 redirects from old URLs to new ones so backlinks still land on real pages. The revival kit in hunter.domains Pro gives you the old URLs and archived content of a domain to work from.
If you plan to completely rebuild the site in a different structure (from /products/ to /blog/), accept that you may lose much of the value of the specific backlinks. This is why respecting the URL structure of the old site matters.
Frequently asked questions
How many backlinks are enough?
There is no magic number. A domain with 20 high-quality backlinks from news and university sites is stronger than a domain with 200 backlinks from spam and parking pages. Focus on referring domains, not total backlinks. What matters most is the quality of the referring sites and whether you plan to keep the URL structure (which preserves link equity).
Do backlinks disappear after a domain drops?
The links themselves do not vanish when a domain expires, but they can break over time. Pages that link to the domain get deleted or moved, and many sites reorganize without maintaining redirects. After a rebuild, links also point at nothing if the old URLs no longer exist. Check that the links are still live before you buy.
Can I check backlinks for free?
Several free tools show a sample of a domain's backlinks, but none shows everything, and their limits change, so check each tool's site. For serious evaluation, a paid backlink tool is worth it if you are buying multiple domains. The free plan of hunter.domains shows core metrics for 5 unlocked domains a day, and much of this analysis is already done for you through the Hunter score and risk flags.
