Referring domains and backlinks get mixed up all the time, and it's not hard to see why. They sound similar, they're related, and most tools show them side by side. But they measure different things, and if you're optimizing for the wrong one, you're sabotaging your ranking potential.
Here's what each metric actually means, how they work, and where to put your energy if you want links that actually do something.
What Are Backlinks?
A backlink is just a link from another website pointing to yours. When a site links to your content, it's vouching for it. Search engines treat that as a trust signal and use it to decide how to rank you.
The catch is that not all backlinks are created equal. Three things determine how much a link is actually worth.
Attribution.
Dofollow links pass SEO value directly to your site. Nofollow links were designed to stop that, but Google no longer treats them as a hard rule, so they can still help in some cases.
Placement.
A link sitting naturally inside an article body carries more weight than one buried in a sidebar or footer. Links that fit the surrounding content feel earned and not like ads, something search engines are pretty good at noticing.
Source quality.
A link from a site Google already trusts is worth a lot. A link from something spammy or irrelevant can actually hurt you.
The best backlinks tick all three boxes: dofollow, embedded in real content, and coming from a source with a decent reputation.
What Are Referring Domains?
A referring domain is any unique website that links to you, regardless of how many times it does so. If one site links to you from twenty different articles, that's twenty backlinks but still just one referring domain.
Think of it like this: imagine you're hiring someone and checking their references. Twenty reviews from the same person don't mean much, but one from twenty different people who all independently vouched for you is a different story.
Two sites can have the exact same number of backlinks but completely different authority profiles depending on where those links come from. A hundred links from one domain versus a hundred links from a hundred different domains are not the same thing, and Google knows it. One looks like a relationship. The other looks like real recognition.
It's also way harder to fake. Getting one site to link to you repeatedly is easy. Earning links from dozens of independent sources means your content actually has to deserve it.
Which One Matters More for SEO?
You need both, but if you're starting somewhere, start with referring domains. A wider range of unique, relevant sites linking to you does more for your authority than getting more links from places that are already linking to you.
More Sources Beat More Links
There's a pretty consistent relationship between referring domain count and ranking potential, and the reason makes sense once you think about it. When multiple independent sites link to you, each one is making its own call that your content is worth citing. That's distributed trust, and it's exactly what search engines are trying to detect.
It's also a lot harder to fake than raw backlink counts. Getting one site to link to you repeatedly is easy. Getting ten different sites to do it means your content actually had to earn it. And when those sites are in your niche, you're building topical authority on top of general credibility. Ten links from ten relevant domains will almost always beat thirty links from one.
But Don't Sleep on Backlinks Either
Referring domains tell you how far your authority spreads. Backlinks determine how deep it goes.
Multiple links pointing to a specific page build that page's authority directly. Contextual links from related content sharpen your topical signals. A varied anchor text profile helps search engines understand what your content is actually about. Referring domains alone can't do any of that.
So What Should You Focus On?
You need both. Referring domains show how widely your content is trusted across the web. Backlinks show how meaningfully. Search engines use both to build a full picture, and leaning too hard on one while ignoring the other always leaves something behind.
The goal is pretty simple: get quality links from relevant sources you don't already have, and make sure the ones you do have are contextual, varied, and actually earned.
How to Get More Referring Domains (and Quality Backlinks)
For a strong, diverse backlink profile, you need strategies that work. Here's a list of proven tactics that can improve both your referring domains and quality backlinks.
Create content worth linking to.
Everything starts here. Original research, useful data, thorough guides, tools that solve real problems: these earn links because they give people an actual reason to reference you. Content that just rehashes what's already out there won't get you anything.
Outreach and guest blogging.
Good content doesn't always find its audience. Reaching out directly, guest posting on relevant sites, getting into expert roundups and HARO responses: these build referring domains while also putting you in front of journalists who are actively looking for credible sources to cite.
Digital PR and brand building.
The best links are the ones you didn't have to ask for. Publish something genuinely worth writing about, original research, a strong point of view, a real finding, and journalists will cover it. Links follow. Building a presence through podcasts, events, and niche publications creates that same pull over time, without you having to pitch every single one.
Competitor backlink analysis.
If sites in your space are linking to competitors but not you, that's a real opportunity. Digging into competitor backlink profiles shows you which content formats earn links in your industry, where the gaps are, and which broken links you could replace with your own content. You're not copying anyone. You're understanding what already works and getting your content in the same room.
Best Practices for Managing Backlinks and Referring Domains
Most people focus so hard on building links that they forget to actually manage what they've built. Here's what to keep in mind.
Don't panic over every weak link.
Do periodic audits, but don't lose sleep over every weak link in your profile. Google filters out most low-quality backlinks on its own. You really only need to get proactive about removal if you've had a manual penalty or a history of shady link building. Otherwise, just stay informed.
Watch your growth patterns.
A sudden spike in backlinks after a long quiet period looks suspicious, even if the links are fine. Slow and steady isn't just a cliche here, it's genuinely what a natural profile looks like.
Relevance beats authority more than you'd think.
A link from a mid-tier site that's squarely in your niche will frequently outperform one from a massive site that has nothing to do with your topic. Most people overweight domain authority. Don't be one of them.
Vary your anchor text.
A profile full of exact-match keyword anchors is a red flag. A natural mix of branded, generic, and keyword-relevant anchors looks organic because it is. That's the whole point.
Frequently Asked Questions
Are backlinks and referring domains the same thing?
Nope. Backlinks are the total number of links pointing to your site. Referring domains are how many unique websites those links come from. One site linking to you ten times equals ten backlinks and one referring domain. The number looks the same. The signal is completely different.
Are referring domains more important than backlinks?
For overall authority, yes. But backlinks build depth at the page level in ways referring domains alone can't. The honest answer is you need both, and anyone telling you to focus on just one is giving you half a strategy.
How do referring domains impact SEO?
They tell Google that multiple independent sites looked at your content and decided it was worth linking to. That's not something you can fake with volume from a handful of sources. The more diverse your referring domains, the harder your authority is to challenge.
What's a good backlinks-to-referring-domains ratio?
There's no magic number, and chasing one is a waste of time. It varies by industry, site type, and content. Get good links from relevant sources and the ratio takes care of itself. Chase the strategy, not the metric.
Conclusion
Backlinks and referring domains aren't competing. They're just measuring different sides of the same thing: how much the web trusts your content and how widely that trust spreads.
Backlinks build authority at the page and topic level. Referring domains show how broadly your content is recognized. You need both. Treating one as enough is just leaving rankings behind.
The sites that hold their positions aren't the ones with the most links. They're the ones with the right links, from the right places, built consistently enough that the profile speaks for itself.
That kind of profile doesn't happen by accident. LinkyJuice helps you build link profiles that reflect real authority: the kind that's earned, relevant, and genuinely hard to compete with. Book a call and let's take an honest look at where yours stands.
