Backlinks vs Referring Domains: Key Differences
A site can have 600 backlinks from one referring domain. Here is what both SEO metrics count, why the totals vary and which report to check first.
If a backlink report shows 600 links, it is worth checking the referring-domains number before getting too excited, because if all 600 links come from a single domain, the tool is probably just counting the same website across hundreds of different pages, often because your link sits in a footer, sidebar or some other repeated template. Those links are not necessarily fake or useless, but there is obviously a huge difference between one website linking to you 600 times and 600 independent websites deciding that your page is worth mentioning.
The reverse can be just as misleading, because six hundred referring domains sounds wonderful on paper, but once you start looking through them and realise that most are scraped pages, automated directories or random sites with absolutely nothing to do with your subject, that impressive number suddenly means a lot less. Both metrics are useful for understanding what is pointing at your site, but neither should be treated as a quality score on its own.
Quick Answer
A backlink is one individual link from another webpage to yours, while a referring domain is the unique website responsible for one or more of those links, which means that a site linking from 50 pages creates 50 backlinks but still counts as one referring domain. The backlink total shows how many links the crawler found and the referring-domain total shows how widely those links are spread, but neither number tells you whether the sources are relevant or worth trusting until you open the report and inspect them.
| Metric | What it counts | Simple example | Use it for |
|---|---|---|---|
| Backlinks | Individual external links to your site or page | Ten pages on one newspaper link to you = ten backlinks | Inspecting the source page, destination, anchor text and link attributes |
| Referring domains | Unique websites with at least one link to you | Those same ten links = one referring domain | Seeing how many separate websites are responsible for the links |
This page-to-page versus website-to-website distinction is also how Neil Patel explains the two metrics, while Ahrefs uses the same basic example, where two links from one publication count as two backlinks from one referring domain.
How one domain can create hundreds of backlinks
When a supplier adds your company to a footer that appears on 600 product pages and articles, a backlink crawler can record 600 individual backlinks even though every one comes from the same domain, and the same multiplication can happen with sidebars, author boxes, partner badges, category pages or copied content. The tool has counted correctly, but the number describes repeated placement across one website rather than 600 separate endorsements.
Nothing about that pattern automatically makes the links fake or useless, because a repeated link from a respected supplier can still send visitors or help people find the relevant page, although it would be dishonest to present the total as if hundreds of different website owners had independently recommended you. This is why the referring-domain number gives the backlink total some badly needed context instead of replacing it.
What do the backlink and domain numbers suggest?
A backlink-to-domain ratio can point you towards the part of a profile worth checking, although it cannot decide whether a link is good or bad, so the examples below should be read as possible explanations rather than automatic verdicts.
| Example report | Possible explanation | What to check |
|---|---|---|
| 600 backlinks, 1 domain | A sitewide footer, sidebar or repeated template | Open that domain and inspect several linking pages |
| 600 backlinks, 50 domains | A mixed profile where a few websites may produce most of the links | Sort referring domains by backlink count |
| 600 backlinks, 600 domains | Broad distribution, or an automated campaign spread across many weak sites | Check relevance, ownership patterns and how the links were created |
| 10 backlinks, 10 relevant domains | A small profile with links spread across genuine sources | Check whether the pages and audiences fit your subject |
None of these ratios proves that a website has a strong link profile or that Google has penalised it, because 600 links from one respected industry publication can be more useful than 600 links from unrelated domains that appear to exist mainly for selling SEO packages. If the numbers look strange, they have done their job by showing you where to investigate, but the judgement still depends on who created the links, where they appear and whether anybody would reasonably follow them.
Are referring domains more important than backlinks?
When you need a quick sense of how widely a site’s links are spread, referring domains are usually the more useful starting point, because ten relevant publications choosing to link once tells a very different story from one publication repeating the same link ten times. Neil Patel therefore recommends earning links from new websites instead of collecting endless extra links from the same source, which is sensible planning advice as long as nobody turns it into the childish rule that a bigger domain count must mean better rankings.
“Referring domains” is a reporting metric created by SEO platforms, while Google’s public documentation describes link analysis systems and PageRank, which examine how pages link to each other alongside many other ranking systems and signals. Google does not publish a required referring-domain target, and there is no official formula promising that a site with 101 domains must outrank one with 100.
The source and method matter far more than a clean-looking total, which is why Google’s link-spam policy lists paid ranking links, excessive exchanges, automated link creation, low-quality directories and widely distributed template links among its examples. One hundred genuine websites with relevant audiences and one hundred disposable domains controlled by the same spam network may produce the same number in a dashboard, but treating them as equal would make the dashboard more intelligent than the person reading it.
Why Ahrefs, Semrush and Search Console disagree
When Ahrefs, Semrush, Ubersuggest and Search Console return different totals for the same website, the disagreement usually comes from the fact that they do not share one backlink database, because they crawl the web on different schedules and apply their own rules for duplicates, redirects and domain grouping. One service may discover a link sooner, keep it longer after removal or place several versions of a site under a different domain total, so a mismatch does not automatically mean that any of the tools is broken.
Google Search Console’s Links report combines duplicate links, groups pages by canonical URL and groups linking sites by root domain, which means that www.example.com and shop.example.com appear under example.com instead of becoming two referring sites. Its tables are also limited to 1,000 rows, giving you another reason not to treat the visible list as a complete database that should perfectly match an external SEO service.
Search Console is useful for seeing Google’s report for a site you control, while an external service becomes necessary when you want competitor research, a broader historical view or different filters, and there is no problem with using both as long as you understand that they are measuring through different databases. When tracking growth, compare dates inside the same tool instead of adding several incompatible totals together and producing one impressive number that means very little.
How to check your link profile without fooling yourself
The easiest way to read a link report is to begin with referring domains and look for concentration, because if one domain supplies most of the backlinks, you already know where to investigate before wasting time admiring the total. Open that domain, inspect several linking pages and work out whether the links come from useful articles, a harmless sitewide element, copied pages or something placed purely to influence rankings.
Once you understand the spread, move into the individual backlink report and check the source page, the page on your site receiving the link, the anchor text and any nofollow, sponsored or ugc attribute, while paying particular attention to repeated templates and clusters of unrelated domains. A smaller collection of relevant links placed where real readers may use them is a healthier sign than a huge total whose sources make no sense, even if the smaller number gives you less to brag about in a screenshot.
Final verdict
Backlinks count individual links while referring domains count the websites responsible for them, so checking both tells you whether a large total comes from many independent sources or one website repeating the same placement across hundreds of pages. I would start with referring domains to understand the spread, then open the backlinks and judge the source pages, placement and reason those links exist, because a dashboard can count what it found but it cannot decide whether any of it deserves your trust.
