What is the Importance of Link Building in 2025? 

Google keeps updating its ranking algorithm to provide the best user experience possible. Especially with the rise of AI-generated content, the importance of link building has only increased, not diminished. 

So if you’re wondering if it’s worth investing the resources into growing your inbound link profile, the answer is a resounding yes. 

Let’s talk a bit more about why that is.

For over two decades, backlinks have formed a cornerstone of Google’s search algorithm, a testament to their enduring importance. 

To understand why, we need to rewind to the internet’s early days.

Initially, search engines relied on simple keyword analysis to determine content relevance. 

This quickly became an easily abused issue with manipulative practices like keyword stuffing.

The Concept of PageRank 

PageRank was basically Google’s way of trying to understand “word-of-mouth” on the internet. 

Instead of people talking, websites were “talking” by linking to each other. These links pass
PageRank, and the more PageRank your website receives, the higher its will show up on search results.

If a website that’s considered a reliable source (like a well-known news site) links to your website, that’s a strong recommendation. 

It’s like a friend telling you, “Hey, this is a good place to get information.”

It’s not just about how many recommendations you get; it’s about who is giving them. 

A high quality link from a respected source carries much more weight than one from a random site with no traffic.

Google’s smart enough to know that not all links are equal. They look at the quality and relevance of those votes.

Internal links also pass PageRank, so you should always optimize your internal linking structure to help boost newer pages. 

Outbound links from your sites to others also pass PageRank, but you don’t “lose” it by linking out. 

And this is how it works to this day – which is why the importance of link building is unlikely to ever diminish. 

It’s important to note that not all backlinks pass PageRank. 

Dofollow links pass link equity (authority) from one website to another, directly influencing its ranking.   

Nofollow links do not pass link equity. They tell search engines not to associate the linking website with the linked website in terms of authority.

While they can still drive traffic, they do not directly improve search engine rankings.

Here’s how you can check if a link is dofollow or nofollow:

  1. Right-click on the link you want to check.
  2. Select “Inspect” or “Inspect Element” (the wording might vary slightly depending on your browser).
  3. This will open the browser’s developer tools, showing you the HTML code of the page.
  4. Look for the <a> tag (the HTML tag for a link).
  5. Within the <a> tag, check for the rel attribute.
  6. If you see rel=”nofollow”, the link is nofollow.
  7. If you see rel=”dofollow”, or no rel attribute at all, the link is generally considered dofollow.
  8. If you see rel=”ugc” or rel=”sponsored”, the link can be considered nofollow as Google as against buying or spamming links to manipulate rankings. 

Improved Rankings on Search Engine Results Pages

Dofollow links from relevant, authoritative sources carry the most weight, since they transfer “link equity,” (aka “link juice”) boosting your site’s authority in the eyes of search engines.

And, of course, links from pages that actually receive traffic are even more valuable. 

The more traffic a page receives, the higher the chance that a user will encounter and interact with your valuable content, or even convert into a customer.

While a link from a page with zero traffic might seem insignificant, it still contributes to your overall link profile and can aid in website discovery. Even a small signal is better than none at all.

It’s also way more important to get links from a wide array of unique websites (referring domains) than to repeatedly get links from the same few sources. 

Each referring domain acts as an independent endorsement and signals to search engines that your website has a more natural and robust backlink profile, ultimately leading to improved search engine rankings.

Highly Targeted Referral Traffic

Referral traffic refers to website visitors who arrive at your site by clicking on a link from another website, rather than directly typing your URL or finding you through a search engine.

While Google traffic is valuable, it can sometimes be broad and less targeted. Referral traffic, on the other hand, can be highly specific.

referral traffic in google analytics

For instance, a link from a niche industry forum can drive highly qualified leads who are already interested in your products or services.

Imagine you sell specialized hiking gear. A quality link on a hiking trail website will drive highly targeted traffic, people who are very likely to be interested in your products. 

This traffic is much more qualified than someone who searched for “hiking” on google, and may or may not be looking to purchase anything.

In addition to the organic traffic of the referring page, a factor that hugely influences how much traffic a link is able to generate is its placement. 

Links closer to the top of the page typically see a much higher CTR (click-through rate) than those further below. 

Examples of effective link placements include:

  • Links within the body of a related blog post on a relevant anchor text.
  • Links on resource pages that cater to your target audience.
  • Links within online forums or communities frequented by your ideal customers.
  • Links placed within the content of a page, rather than in a footer or sidebar, are more likely to be seen and clicked.

Increased Domain Authority

Domain Authority (DA) and Domain Rating (DR), are metrics developed by SEO tools like Moz and Ahrefs, to estimate a website’s overall strength. 

These metrics essentially look at a site’s backlink profile and quantify it with a single, easily digestible score. 

They analyze the link quality and quantity, check aspects like the number of unique referring domains, the authority of those domains, and the overall relevance of the links. 

A robust and diverse backlink profile naturally translates to a higher DA/DR score.

While DA/DR isn’t a direct search engine ranking factor in Google’s algorithm, it’s typically associated with better search engine performance. 

This is because both DA/DR and Google’s ranking system revolve around the strength of a website’s backlink profile. 

It’s important to keep in mind that these scores are predictions, and not guarantees of ranking.

Beyond organic traffic, marketers leverage DA/DR as one of the core metrics for identifying collaboration opportunities. 

Reputable websites with higher DA/DR scores are often prioritized for guest posting, link exchanges, and other partnership initiatives. 

While DA/DR shouldn’t replace in-depth analysis, it serves as a convenient and insightful metric for evaluating a website’s overall strength and potential.

Outrank Your Competition

Even when your content and offerings are on par with your competitors, a stronger backlink profile can be the deciding factor in outranking them in search results.   

Imagine two websites selling identical products. 

One has built tons of links from numerous authoritative industry publications, high-traffic blogs, and relevant directories, while the other has a limited number of backlinks from less reputable sources. 

Who’s going to rank higher? 

You guessed it – the one with more, better links.

Frequently Asked Questions (FAQ)

Yes, absolutely. 

With the ease of content creation through AI, backlinks have become even more critical in verifying credibility and authority. 

They act as signals to search engines that your content is trustworthy and valued by other reputable sources, helping it stand out in a crowded digital landscape.

Focus on creating valuable, shareable high quality content that naturally attracts links. 

Engage in outreach to relevant websites and blogs, and use a variety of link building strategies such as link insertion, guest posting, broken link building, listicles, etc. 

Build genuine relationships with other website owners in your niche, and always prioritize quality over quantity.

Dofollow links pass link equity and influence search rankings, while nofollow links do not. 

Dofollow links are generally more valuable for SEO, but nofollow links can still drive website traffic and increase brand awareness. 

A healthy backlink profile should ideally have a mix of both.

There’s no magic number. 

The quality and relevance of your backlinks matter far more than quantity. 

Focus on acquiring natural links from authoritative websites in your niche. 

A few high quality links are more effective than numerous low-quality ones.

Buying backlinks is strongly discouraged and can lead to penalties from search engines. 

Google’s algorithms are designed to detect manipulative link schemes, and participating in them can harm your website’s reputation and search engine rankings. 

It is always best to build your external link profile organically.
