- Target Domain: The specific website or webpage that receives a backlink.
- Authority Score (as): A proprietary Semrush metric that measures a website's authoritativeness and quality on a scale of 0 to 100.
- Domain Rating (dr): A proprietary Ahrefs metric representing the strength of a website’s backlink profile.
- Domain Authority (da): A search engine ranking score developed by Moz that predicts how likely a website is to rank.
- Website Popularity Rank (wpr): A metric developed by Tranco that measures domain popularity compared to other sites based on visitors and page views.

- Broken Link Building: An SEO tactic where you find dead links on external sites and suggest your own content as a replacement.
A referring domain, also called a linking domain, is an external website that provides one or more backlinks to your site. While a single website can link to you hundreds of times, it still counts as just one referring domain. Tracking this metric helps you understand the diversity and authority of your link profile.
What is a Referring Domain?
A referring domain is any unique website that "refers" traffic or authority to your site via hyperlinks. If the New York Times links to your homepage five times, you have five backlinks but only one referring domain. If both the New York Times and Forbes link to you, you have two referring domains.
Why Referring Domains Matter
Referring domains are a primary indicator of a website’s quality and trustworthiness in the eyes of search engines like Google. High-quality external endorsements can lead to higher rankings and increased organic traffic.
- Higher Rankings: Studies show that [pages ranking #1 in Google have an average of over 200 referring domains] (Semrush).
- Traffic Generation: There is a direct correlation between unique linking sites and visitors, as [the vast majority of web pages with zero referring domains receive no traffic from Google] (Ahrefs).
- Brand Exposure: Gaining links from multiple unique domains reaches a broader audience than getting multiple links from the same site.
- Authority Building: Search engines use these domains as "votes" of confidence. Links from reputable, high-scoring sites (such as those with a high Authority Score) carry more weight.
How to Check Your Referring Domains
You can monitor your linking domains using both free and paid SEO tools.
Google Search Console
Navigate to the "Links" section and look at the "Top linking sites" report. This shows which domains link to you most often, how many of their pages contain links, and how many of your target pages they link to.
SEO Tools (Ahrefs, Semrush, LinkMiner)
Enter your URL into a backlink analytics tool to see a comprehensive list of referring domains. These tools provide additional data such as: * Authority Metrics: Scores like DR, DA, or AS to estimate site quality. * New vs. Lost Domains: Tracking which sites recently started or stopped linking to you. * Anchor Text: The specific text used for the hyperlinks.
Google Analytics
Check the "Referrals" section under the Acquisition tab. This records "referral visits" from external domains. If a visitor clicks a link on a third-party site to reach you, the domain is recorded here.
Best Practices for Increasing Referring Domains
- Create linkable assets: Publish original research or case studies. Studies indicate that [long-form content earns approximately 80% more referring domains than short posts] (Mangools).
- Fix broken links: Identify dead links on authoritative sites using tools like LinkMiner and suggest your site’s functional content as a replacement.
- Find unlinked mentions: Search for places where your brand is mentioned without a link and ask the author to add one.
- Become a source: Respond to media requests for expert commentary to earn links from news organizations.
- Diversify sources: Seek links from varied sources like resource pages, directories, and guest posts rather than relying on a single type of site.
Common Mistakes
Mistake: Acquiring a massive number of domains in a very short time. Fix: Grow your link profile at an organic pace to avoid being flagged by search engine algorithms.
Mistake: Focusing only on the total number of backlinks. Fix: Monitor the number of unique referring domains, as 100 links from one site is often less valuable than 10 links from 10 different sites.
Mistake: Accepting links from "spammy" or low-quality domains. Fix: Regularly audit your profile and consider disavowing links that violate Google’s spam policies if they are harming your rankings.
Mistake: Forgetting internal URL filters in analytics. Fix: Configure your filters in tools like Adobe Analytics to ensure your own company’s domain does not appear as a "referring domain."

FAQ
What is a "good" number of referring domains? There is no universal benchmark. You should compare your profile to your direct competitors. Ideally, you want to match or exceed the number of high-quality referring domains held by the pages you wish to outrank.
What does it mean if I see "googleusercontent.com" as a referring domain? This typically refers to traffic coming from Google’s cached pages (stored copies of sites) or pages viewed through Google Translate.
What is the "Typed/Bookmarked" category in analytics? In Adobe Analytics, this indicates the visitor arrived without any referrer data, such as by typing the URL directly, using a bookmark, or certain types of redirects.
Can I lose a referring domain? Yes. You lose a referring domain if the external site removes all links to your website or if the linking page is taken down. If the site still has one other link to you elsewhere, you have lost a backlink but not the referring domain.
Should I disavow low-quality referring domains? Google is generally good at ignoring spam. However, if you have been penalized or if a majority of your links are from spammy sites, you should follow official guidelines to disavow them.
