As a website owner or agency, you’re probably seeking ways to improve your site’s rankings and attract more visitors. While some may argue that the importance of backlinks has diminished in recent years, high-quality backlinks still play a significant role in improving your website’s search engine rankings and driving traffic to it. 

This article delves into the importance of referring domains for SEO and provides insight on how to analyze them using various metrics. Whether you’re new to SEO or you’re a seasoned pro, tapping into the potential of referring domains is key to improving your website’s search engine rankings. 

So, let’s hop right in!

What is a referring domain

A referring domain is an external website that links to your website. This can include a variety of sources, such as corporate blogs, news sites, educational and governmental websites, social media platforms, forums, online directories, and other websites in your industry or niche. It’s important to keep in mind that not all referring domains are created equal. Links coming from authoritative and relevant websites hold more value than links from low-quality websites.

Referring domains are an important SEO metric because they signal to search engines that your content is valuable and relevant. The greater the number of high-quality referring domains that link to your site, the more likely it is that search engines will view your site as authoritative and relevant in your niche or industry. For this reason, you’ll want to focus on building a diverse, high-quality backlink profile. This will help to improve your website’s search engine rankings and attract more traffic to your site.

What is the difference between a referring domain and a backlink

The terms “referring domain” and “backlink” are often used interchangeably, but they actually refer to different things. A backlink is simply a link from one website to another, but a single referring domain may contain several links that lead to your website.

When analyzing backlinks, you should closely examine the specific links pointing to your site and their anchor texts. When analyzing referring domains, you should not only consider the overall number but also evaluate the quality of sites linking back to your site. This approach allows you to better understand the diversity and strength of your backlink profile. It’s also useful for identifying areas where you need to improve. By analyzing referring domains, you can identify the high-quality sites that link to your site and focus on building relationships with similar sites in your industry.

Backlinks and referring domains are both important SEO metrics to track. By carefully analyzing each, you can better understand your website’s authority, relevance, and SERP visibility.

Why referring domains are important

Referring domains are important for SEO because they are a major ranking factor for search engines. Whenever your website receives backlinks from authoritative domains, Google considers the content that’s being linked to to be trustworthy. This leads to your site having higher search engine rankings and more organic traffic.

Referring domains are especially important because they indicate the degree of diversity and overall quality of your backlink profile. If your website has lots of referring domains, this indicates to Google that your site has received backlinks from a wide range of sources, which strengthens its authority. Having a diverse range of referring domains also suggests that your website’s content is relevant and useful to a broad audience.

With Google, it works the same way.

Whenever your website gets an endorsement (in the form of a backlink) from a new domain, Google appreciates it. When the same domain endorses you again, Google still appreciates it, but the value of that second show of support pales in comparison to that of a new domain “recommending” your website. So, while getting the tenth link from the same website won’t get you into hot water, it won’t benefit your website as much either.

If your website has a low number of referring domains, it will be seen as less trustworthy and will struggle to rank well in search results. Similarly, if your site receives backlinks from low-quality or spammy domains, this can harm its reputation and can even result in a penalty from search engines.

This is one major reason why you need to pay attention to the referring domain metric, which shows the true value of your backlink profile. Many SEO professionals analyze their referring domains to identify areas for improvement in their backlink profiles. You can use what you learned from your current backlink profile to take the necessary steps in increasing the number of high-quality referring domains to your site. 

Now, let’s look into some ways to analyze referring domains for better SEO results.

How to check referring domains

Many third-party tools, including SE Ranking, help SEO agencies analyze their backlinks and referring domain metrics. Our tool for backlink lookup, for instance, can pull an entire site’s SEO data and display all of it on a single dashboard, enabling you to analyze its referring domains and backlinks side by side. 

SE Ranking’s Backlink Checker assists you in finding:

  • The number of referring domains and backlinks
  • The pace at which the website acquires new backlinks and referring domains
  • The portion of links pointing to the homepage compared to other pages
  • The anchor text for both referring domains and backlinks
  • The geographical distribution map

Let’s take a closer look at each metric in more detail to find out what it means:

  • The number of referring domains and backlinks. By comparing the ratio between referring domains and backlinks, you can quickly determine how diverse your backlink profile is. You can also assess the quality of your backlinks from .edu or .gov domains, as well as the ratio of dofollow and nofollow backlinks. 
  • The rate of acquisition of new referring domains and backlinks. By tracking the growth rate of your backlink profile over time, you can identify any spikes or drops in growth to make informed decisions about your outreach strategy. 
  • The distribution of links pointing to the home page and other pages on your website. A healthy backlink profile should have a mix of links pointing to the home page and other pages on your website. By analyzing this metric, you can ensure that your link structure is well-optimized.
  • Anchor text distribution for both referring domains and backlinks. Anchor text is the clickable text that appears as a hyperlink. By analyzing the anchor text distribution for both referring domains and backlinks, you can ensure that your anchor texts are relevant and diverse. 
  • The geographical distribution map. This metric shows where the majority of your backlinks are coming from. By analyzing this data, you can tailor your outreach efforts to specific regions and identify potential opportunities for growth. 

We highly suggest that you analyze all of these metrics. This will give you a better understanding of your backlink profile and help you make informed decisions that lead to improved SEO results, including higher search engine rankings and increased organic traffic.

How to get more referring domains

Now that you know why referring domains are crucial for SEO, let’s look into some ways to get them. Here are some of the most popular and effective ways to acquire new referring domains:

  • Guest posting: Writing high-quality articles for other websites in exchange for a backlink to your site.
  • Broken link building: Finding broken links on other websites and offering to replace them with a link to your content.
  • Skyscraper technique: Creating high-quality content that outperforms your competitors’ content and reaching out to sites that link to your competitors, asking them to link to your content (which is better) instead.
  • Infographics: Creating informative and visually appealing infographics that other websites may want to share on their site, which will include a link back to your website.
  • Competitor analysis: Analyzing your competitors’ backlink profiles to see which referring domains they have and identifying opportunities to get links from those sites.
