What Is a Referring Domain?
A referring domain is a website that links to your website.
It’s the source site behind one or more backlinks.
Example:
If abc.com links to your page, then abc.com counts as 1 referring domain.
Referring Domains vs Backlinks Difference
These two terms are connected, but they measure different things:
- Referring domains = the number of unique websites linking to you
- Backlinks = the number of total links pointing to your site
Quick examples:
- abc.com links once → 1 referring domain, 1 backlink
- abc.com links 10 times → 1 referring domain, 10 backlinks
- 10 websites link once → 10 referring domains, 10 backlinks
This is why most SEO tools track both numbers.
Why Referring Domains Matter for SEO
Referring domains help you understand how strong your website looks online.
In general, links from more unique and relevant sites can support better rankings.
They help you:
- Spot new backlink opportunities
- Compare competitor referring domains
- Track growth and drops over time
- Keep your link profile healthy

What to Do With Referring Domains for SEO
Referring domains don’t just show data—they show where to act.
Find competitor backlink opportunities
Look for websites linking to competitors but not to you.
Those sites are already linked in your niche, so that they can be easier outreach targets.
To speed this up, run a backlink gap analysis and build a focused outreach list.
Focus on quality, not quantity
One strong link from a real, relevant site can be better than many weak links.
Aim for websites that match your topic and have genuine content.
Recover lost links
If you see a domain drop off, check what changed.
A page may have moved, a link may be broken, or content may be updated. Many lost links are recoverable.

Frequently Asked Questions
-
A referring domain is the website linking to you. A backlink is the actual link. One domain can send many backlinks.
-
No. Nofollow links can still send traffic, build trust, and make your link profile look natural.
-
A drop in referring domains usually means that some websites are no longer linking to your site. This can happen when a linking page is deleted, your URL changes, and the old link starts showing a 404 error, or the site owner removes your link during an update. Sometimes the link is still there, but it has changed from dofollow to nofollow. In other cases, the numbers drop because your SEO tool is updating its database or having a temporary crawl issue. It can also happen when search engines or website owners remove spammy or low-quality links.
-
Yes. One referring domain can still help your SEO and bring real traffic, especially when the website is trusted and related to your topic. However, too many links from the same site often add less value over time. For stronger SEO growth, it’s usually better to earn links from many different domains, because link variety is a clear sign that more websites trust your content.
-
There is no fixed “perfect” number of referring domains. It depends on your niche, your competitors, and how strong your website already is. The best approach is to grow steadily by earning relevant, high-quality referring domains over time. Even a small number of strong domains can help more than many weak ones. Track your progress, compare with competitors, and focus on links that come from real websites in your industry.
