When it comes to search engine optimization (SEO), there are many factors that affect a website’s visibility and ranking.

Of these, backlinks and referring domains play a major role. However, new marketers often get confused about the difference between backlinks and referring domains and which domains are more important.

In this article, we will break down the differences between backlinks and referring domains. Plus, we will give you practical steps to check the backlinks and referring domains of any website.

What is a backlink?

A backlink is a link that takes users from one webpage to another. When another website links to your website, it counts as a backlink.

You can think of it as an online endorsement or “vote” for your content. The more credible the websites linking to your site, the higher its authority and credibility with search engines.

For example, you write an informative article about medium-sized dog breeds.

Another website, impressed by your content, includes a link to your article in their own blog post about pet care. That link becomes a backlink to your article, increasing its visibility and online reach.

The more high-quality backlinks you acquire, the more “popular” your site appears on search engines like Google, which can improve your ranking in search results.

What is a referring domain?

A referring domain is any unique website that has one or more backlinks pointing to your site. Simply put, it is a website that acts as a source of backlinks to your site.

Unlike backlinks, which count individual links, referring domains focus on the number of unique websites linking to your content.

Going back to our dog breed article example: If a well-known pet magazine links to your article, the pet magazine counts as a referring domain. Even if it only links once, it still counts because it is the source of that backlink.

Search engines evaluate both the quality and quantity of referring domains to gauge the relevance and popularity of your website, which ultimately affects your organic search rankings.

Referring Domains vs. Backlinks: How Do They Affect SEO?

Referring Domains vs. Backlinks: How Do They Affect SEO?

Both backlinks and referring domains play an important role in improving your site’s SEO performance.

Backlinks serve as endorsements for your website and are a core part of effective link building. The more backlinks (endorsements) you get from trusted sources, the higher Google will rank your site.

However, not all backlinks are of equal value. Some links have more authority and have a stronger impact on your SEO.

Several factors influence the strength of a backlink. One major factor is the relevance of the page linking to you. A backlink from a page closely related to your topic is more beneficial than a backlink from an unrelated page.

Another important factor is the anchor text of the link. Search engines use this text to understand the content of your page. Using descriptive anchor text works better than generic phrases like “click here.” Including keywords in anchor text can be very effective, although over-optimization can lead to Google penalties.

The credibility of the site providing the backlink is also important. A link from a well-established site, like The Washington Post, will have a stronger impact than a link from a newly launched site.

Backlinks with lower authority still add value and will not negatively impact your rankings.

Referring domains work in a similar way to endorsements and influence the strength of each backlink. Like backlinks, some referring domains carry more weight than others. Evaluating the quality of a referring domain follows the same criteria as evaluating backlinks.

Referring domains gain more value when they are relevant to your niche and are recognized as trustworthy by search engines.

If you want to check the quality of the referring domain, tools like Ubersuggest can help. Using these tools for backlink monitoring provides the domain authority for each backlink pointing to your site and shows you the page authority of the specific page linking to it.

Why does Google place so much importance on referring domains? 

Think about choosing a movie to watch and asking for recommendations.

If a lot of people recommend the same movie, you might assume it’s worth watching.

Conversely, if only one or two people recommend a movie repeatedly, it may not seem credible.

Google applies the same logic to backlinks.

When multiple referring domains link to your website, it’s a sign that many site owners value your content.

If most of the backlinks come from just a few domains, it doesn’t carry the same weight.

In extreme cases such as getting too many links from a single domain it can violate Google’s guidelines.

Some try to manipulate search rankings by buying or building links from low-quality sites, but Google’s algorithms can quickly detect these tactics.
