The Impact of Link Building on Domain Authority

With the changing times, SEO techniques have upgraded. But link building has remained a critical and highly effective tactic for enhancing a website’s authority and search engine visibility.

As link building is considered one of the most important SEO practices by Google or other search engines to check whether they may put your site higher or lower on search engine results pages, you have to find the high-quality sites you may link to or from.

Now the question is how to understand the quality of a website. This is where link building metrics come into the game. You can easily figure out what websites have the higher domain authority that you may approach to gain backlinks, resulting in increasing your site authority as well. Further, these metrics assist you in measuring the overall success of your link building campaign.

Before we directly jump to the impact of link building on Domain Authority, we would like you to understand a few things first.

1. What is Domain authority?

Domain Authority (shortly known as DA) signifies a website’s possibility of appearing higher on search engine results pages (SERPs). It ranges from 0 to 100 on a logarithmic scale. The higher the DA score is, the better the website authority.

2. What is DA (Domain Authority) and DR (Domain Rating)?

Both DA and DR are similar and considered one of the most crucial link building metrics. While DA or Domain Authority is developed by Moz, on the other hand, DR or Domain Rating is developed by Ahrefs.

These metrics indicate the quality of backlink profiles on a website. It further decides the authority of a website. It is based on a logarithmic scale with scores ranging from 0 to 100. The higher the score of domain rating or domain authority a website has, the better the website gets search engine rankings as well as authority in that niche or industry.

Another essential thing that you should remember is that increasing DA or DR from 0 to 10 is much easier than doing the same from 50 to 60.

Some of the other benefits a high DA score can give your website are –

  • Brand awareness.
  • Increased online visibility.
  • More organic traffic.
  • Search engines make your site a thought leader in your industry or particular niche.
  • Outperforming your competitors in search engine rankings.

3. Connection of DA and PA

As you know what a domain authority is, we will explain the PA.

PA or Page Authority is also a link building metric used by SEO specialists. A page authority defines the quality of backlinks only a single page has. 

So, when we interconnect the DA and PA, in simpler terms it stands for –

PA indicates the strength of a page on your website, while DA indicates the strength of your entire domain. Page authority score also ranges from 0 to 100 on a logarithmic scale like DA. Moreover, it is usually easier to score from 0 to 10 than it is to score from 50 to 60 for PA.

When you need backlinks from a website, audit the DA for the particular website. If it has a DA over 50, it is considered a quality website. Hence, you can approach the website for backlinks.

At the same time, if you find any relevant page that you want to acquire a backlink whose PA is 55, and DA for that website is 20, you can still choose to build links. Even though the DA is low, it won’t affect much due to the high PA for that specific page.

4. What is the significance of Link Spam Score?

A link spam score is a metric developed by Moz that provides a score in percentage for every link. It has three stages – 

  • 1-30% is known as a low spam score.
  • 31-60% is known as a medium spam score.
  • 61-100% is known as a high spam score.

The lower the score is, the better the link. On the other hand, the higher the score is, the more harmful it is for the website from an SEO perspective. Additionally, a higher link spam score terms a link as a low-quality or spammy link. Therefore, stick to building low spam score links that help your website get many SEO benefits.

5. Link Building Strategies to Boost Domain Authority

As you have been familiar with the important link building metrics, we will discuss what link building strategies help increase the domain authority.

High-Quality Content

The cornerstone of every effective link building strategy is creating remarkable content that other people want to link to. Make efforts to produce informational, valuable, and engaging content that fulfills the needs and interests of your audience. As a result, other websites are more likely to link back to your content as a reliable source if it offers value.

When more people start linking to your content, such as blogs, articles, product listings, etc., search engines will treat your site as a good source of information on that niche and enhance your DA.

Guest Blogging

Guest blogging is also a great link building strategy that you might take help to improve the domain authority for your website. But when you approach any website owner to be their guest blogger, remember to address the higher DA websites from your relevant niche or industry.

There is another point we want you to understand when addressing any website owner is that you must focus on what benefits your blog or article can bring to their readers. If your blog is of quality and informational, they will give you a backlink. Hence, this authoritative backlink will improve your domain strength.

Broken Link Building

In this method, you have to find broken links on other websites from your niche and contact the webmasters to recommend replacing such links using relevant content from your website.

Although the broken link building method needs some thorough research skills and outreach efforts, it is worth the shot. It can lead to earning high-quality backlinks. 

So when search engines crawl and index your links profile, they will understand that your website has good information that can be shared online with users in that niche, resulting in improving your DA.

Using Relevant Anchor Text

Anchor text plays a significant role in enhancing your page authority, which ultimately impacts your domain rating or domain authority.

When you build any internal or external links on your website, you probably put a text while linking the web pages. This text is known as anchor text. So, while you create an anchor text for any relevant page, the text should match the landing page’s main content. It helps your users and search engines understand what the page is about.

For example, when you put an anchor text such as “a dog’s tale” on the page you are linking to, your users and search engines will easily get that the linked page is about a dog. 

But if the linked page is about a cat, then the anchor text is wrong and misleading. So, put anchor text with relevant keywords that may impact your overall DA or DR score positively.

Last Words

You can even conduct an analysis of your top competitors’ backlinks profile. It will help you understand what relevant websites they have reached out to to make a robust link profile. 

Once you get the websites, sort the list according to the higher DA score. Reach out to them for building links.

Refrain from acquiring backlinks from spammy or low-quality websites that will affect your DA score badly.

But when you engage yourself to receive backlinks from authoritative sources, Google will increase your site authority, leading to setting up a strong online presence and more organic traffic.


Domain authority matters in link building because it indicates the credibility and influence of a website. Higher domain authority can lead to stronger backlinks, better search engine rankings, and increased online visibility.

Domain authority is influenced by factors like the quantity and quality of backlinks, website age, content relevance, and overall site performance.

Low domain authority can result from having few or poor-quality backlinks, thin or irrelevant content, technical issues, and limited site visibility.

Domain authority and domain rating are both significant, but they are metrics from different providers (Moz and Ahrefs). Both measure site strength, so it’s best to consider both when assessing a website’s credibility.

Quality backlinks from authoritative websites, relevant and valuable content, and consistent SEO efforts can increase a website’s domain rating.

Yes, higher domain authority often correlates with increased organic search traffic due to better search engine rankings and improved online visibility.

High domain authority brings benefits such as better search rankings, more referral traffic from quality backlinks, increased trust from users, and a stronger online presence.

The number of backlinks needed for a specific domain authority can vary widely. It’s not solely about quantity; quality, relevance, and diversity of backlinks play crucial roles.
