Referring Domains vs Backlinks – What’s the Difference?

When comparing referring domains vs backlinks, remember this: backlinks are individual links to your website, while referring domains are the distinct domains those links come from. One website can give you hundreds of backlinks but still count as one referring domain. More links don't automatically mean better rankings.

What each number actually counts

A backlink is an incoming link from another website. If a supplier links to your homepage from an article, that's a backlink. If another article on that supplier's website links to your services page, that's another backlink.

The supplier still represents one referring domain. You're counting the source website once, rather than counting every link it sends you.

Here's a hypothetical example for a Cheshire business:

Website linking to your business Backlinks found Referring domains
Local newspaper 8 1
Trade supplier 4 1
Chamber of commerce 1 1
Total 13 3

Those 13 links come from three domains. They don't represent 13 different organisations recommending your business.

Most tools group domains using their own rules, including how they handle subdomains. That can produce differences between reports, but the basic distinction stays the same.

Also, these are external links, not links between pages on your own website. Your navigation menu doesn't add referring domains to your backlink profile.

The simplest way to understand referring domains vs backlinks is to ask two questions: how many links were found, and how many distinct domains provided them?

Imagine a web designer adds a link to your business in the footer of a large website. That footer appears across 600 pages.

A backlink tool might discover hundreds of links, depending on how it crawls and reports repeated links. Your referring-domain count could increase by just one.

That's not automatically suspicious. Repeated links can come from perfectly ordinary website features. A trade association might list its members across several pages. A publication might mention your business in multiple articles over several years.

But it explains why a report saying “we secured 600 backlinks” needs a follow-up question. Did your business appear on hundreds of different websites, or did one website repeat the same link everywhere?

Those are very different outcomes. Neither should be presented as the other.

A large backlink total isn't proof of a large outreach campaign. It might reflect useful ongoing coverage, a site-wide footer link or a technical change that made existing links easier for a tool to discover.

The opposite can happen too. A website redesign might remove hundreds of repeated links while leaving one relevant article linking to you. Your backlink count drops dramatically, but you've not necessarily lost hundreds of separate recommendations.

Don't panic over the size of the change before checking its source.

For understanding how widely your business is linked to, referring domains are usually more informative. They help separate broad coverage from lots of repeated links on a handful of websites.

That doesn't make them a ranking score.

Ten relevant, genuine referring domains can be more useful than hundreds of unrelated domains created to sell links. Even apparently different websites might share an owner or exist within the same link-selling network. A domain count doesn't establish independence or quality.

Individual backlinks still matter because their context and destination matter. A useful article linking directly to your emergency plumbing page isn't equivalent to an obscure directory linking to your homepage.

A second link from an existing referring domain can also be worthwhile. It might reach a different audience, support another service page or send actual visitors. It hasn't become worthless because your domain count stays flat.

Google's link spam policies describe links created primarily to manipulate rankings. A bigger spreadsheet doesn't make those tactics safer.

When assessing referring domains vs backlinks, look beyond quantity to relevance, placement and purpose. Our guide to what makes a good backlink explains those quality checks in more detail.

A report should tell you what changed and why it matters. “Backlinks up 340%” isn't enough, especially when nobody can explain where those links came from.

Start with the reporting scope. Is the figure for your whole domain, one service page or a particular subdomain? Are you seeing currently live links or every link the tool has ever discovered?

Then look for evidence behind the headline:

  • Source domains: Which websites actually linked to you, and are they relevant to your business?
  • Linking pages: Where does each link appear, and can you open that page yourself?
  • Destination pages: Does the link point to the page customers need, or somewhere irrelevant?
  • New and lost links: What appeared or disappeared during the reporting period, rather than across the site's entire history?

Domain Rating and Domain Authority are third-party metrics, not scores issued by Google. They can help with comparisons, but they don't prove that a website is relevant or that a particular link will help you rank.

Treat them as supporting information, not the verdict.

A useful referring domains vs backlinks report explains the sources behind the numbers. If an agency won't show you those sources, a colourful graph isn't much reassurance.

Why different SEO tools show different totals

Google Search Console, Ahrefs, Semrush and other tools don't share one complete, identical database of the web.

Each discovers links through its own systems. Crawl timing, coverage, filters and the treatment of duplicate links all affect the totals you see.

Google's Search Console Links report documentation explains that its report provides a sample of links, not a comprehensive list. It also groups and deduplicates information, so its numbers shouldn't be expected to match another tool exactly.

A link can exist before a commercial tool discovers it. A removed link can remain visible in historical data. Neither situation automatically means your agency is lying or Google has missed your website.

The practical fix is consistency. Compare the same tool, the same scope and the same filters over time. Comparing last month's live-domain report with this month's historical-backlink report tells you very little.

Also check whether you're viewing followed links only or all links. Attributes such as nofollow and sponsored give search engines additional information about the relationship; they aren't a simple useful-versus-useless label for your business.

For referring domains vs backlinks comparisons, consistent measurement is more useful than trying to force every dashboard to agree.

Your competitor has 400 referring domains and you have 35. That's a reason to investigate, not a reason to order 365 links by Friday.

Their domain might be older. They might have national press coverage, several locations or a previous business attached to the same website. Some links could be irrelevant leftovers that contribute little.

Compare the pages competing for the searches you actually want. A rival's popular blog post might attract most of its links while its local service page has very few.

Use the comparison to find realistic opportunities:

  • Relevant sources: Identify publications, associations and suppliers that cover businesses like yours.
  • Linked pages: Check whether links support the competing service page or unrelated parts of the website.
  • Reasons for coverage: Look for useful resources, genuine partnerships or newsworthy business activity.
  • Repeat patterns: Notice whether large backlink totals come from just a few heavily repeated sources.

Don't copy every directory entry or chase every impressive-looking metric. A site that links to your competitor isn't automatically suitable for you.

This is where referring domains vs backlinks becomes a useful business comparison: it helps you distinguish broad, relevant coverage from repeated links that inflate the total without revealing much about the competitor's advantage.

For a local business, useful sources often come from relationships and activity that already exist outside SEO.

A supplier may have an installer directory. A trade body may list genuine members. A local publication may cover a business story because it's relevant to its readers, not because someone emailed asking for “link juice”.

The link needs to make sense in context. A Cheshire electrician doesn't need hundreds of links from unrelated overseas lifestyle blogs just because a seller offers an attractive price per link.

A legitimate source can have a modest third-party authority score and still be useful. It might put you in front of the right customers, establish a real local connection or provide a relevant reference to your services.

Not every mention will include a link. And a genuine link won't necessarily create an immediate ranking change. Both are reasons to avoid promises based on neat monthly quotas.

When reviewing referring domains vs backlinks for a local business, I'd rather understand the relevance of each new source than admire a rising total with no explanation.

Links also sit alongside your Google Business Profile, website content and other local search factors. Our local SEO service addresses that wider picture, rather than treating link building as a substitute for everything else.

You don't need to become an SEO analyst to challenge a report. You need clear questions and answers that don't disappear into jargon.

If an agency says its link campaign is working, ask for evidence you can inspect. A screenshot of an upward line isn't evidence of useful placements, and “our methods are confidential” doesn't explain what your money bought.

These questions separate activity from substance:

  • How many new referring domains appeared? Ask separately from the number of new backlinks.
  • Which linking pages can I inspect? You should be able to see the actual placements.
  • Which pages on my website received links? The destinations should fit your business priorities.
  • How were the links obtained? Ask about editorial coverage, directories, commercial arrangements and any required link attributes.
  • What business progress are we tracking? Relevant search visibility, qualified visits and enquiries provide context for the link work.

Not every placement produces a measurable enquiry, and rankings can't be attributed neatly to one link. An honest agency should say that rather than invent certainty.

If referring domains vs backlinks figures are the only success measures in your report, ask what they're supposed to demonstrate. More activity is not the same thing as more customers.

What to do with the numbers next

If you have lots of backlinks but very few referring domains, check which websites generate the repetition. It could be normal coverage, site-wide links or a poor campaign padded with volume. The count alone can't tell you which.

If you have few backlinks and few referring domains, look for relevant opportunities before assuming you're behind. Your business might need better visibility beyond its own website, but it may also need clearer service pages or basic technical repairs.

And if both totals look healthy while enquiries remain weak, don't automatically buy more links. Check whether you're visible for searches with buying intent and whether visitors can understand your offer and contact you easily.

That's the commercial point of referring domains vs backlinks: use the distinction to diagnose what you've got, not to set an arbitrary target that somebody can sell you.

Our link building service is the relevant place to discuss work on your site's external links. Start with your current profile and business priorities, rather than a promise to deliver a suspiciously tidy number every month.

You want links that have a reason to exist. Not a spreadsheet full of websites nobody would visit voluntarily.

Frequently Asked Questions

Can one referring domain give you thousands of backlinks? Yes. A website can link to you from thousands of pages, particularly through repeated navigation, templates or footers. Depending on the tool's reporting rules, those may appear as many backlinks from one referring domain. The volume doesn't mean thousands of separate businesses have recommended you, or that every link adds equal value.

How many referring domains does a small business need? There's no universal target. Competition, relevance, your website's content and the searches you're targeting all affect what's needed. A local business shouldn't copy the totals of a national retailer. Review relevant competitors and realistic link opportunities, then judge progress alongside search visibility and enquiries rather than an arbitrary domain quota.

Why do Search Console and Ahrefs show different link counts? They use different discovery systems, reporting scopes and methods for grouping links. Search Console's Links report isn't a complete inventory, and Ahrefs reports what its own systems discover. When comparing referring domains vs backlinks over time, use consistent settings within one tool instead of expecting two separate databases to produce identical totals.

Will more referring domains guarantee better rankings or more enquiries? No. Additional domains may be irrelevant, manipulative or simply unrelated to the pages you want to rank. Even worthwhile links don't guarantee customers if your website targets the wrong searches or makes contacting you difficult. Assess the sources, the linked pages and the business results together, rather than treating growth in one metric as proof of success.
