9 Benefits Of Link Building For SEO And AI Search in 2026

Here’s the truth about link building…

It’s hard work, takes time, and requires real skill to be successful. And most SEOs avoid it because doing outreach makes them feel uncomfortable.

But it’s also one of the essential pillars of SEO.

The first result in Google has 3.8x more backlinks than sites ranking in positions 2-10. That's not dumb luck, that's link building at work.

And that’s just the tip of the iceberg.

Backlinks don’t just boost rankings in Google. They also drive relevant referral traffic, build brand signals, and even increase the likelihood that AI search engines like ChatGPT and Perplexity will recommend you.

If you’re still on the fence about link building, you’re missing out on the one thing that separates first-page rankings from the rest.

So I’m going to break down the 9 biggest benefits of link building so you can clearly see why it’s a worthwhile investment.

How Does Link Building Help SEO?

Before we dive into the specifics…

…let’s get something straight.

Think of backlinks like votes from other websites.

Google uses these “votes” as a way to gauge whether your website and content can be trusted. The more high-quality backlinks you have, the more confident Google is in recommending your website to its users.

Put simply – Backlinks are Google’s trust currency.

This was confirmed in the Google search algorithm leak, where we discovered the “SiteAuthority” score. Essentially, a metric baked into Google’s algorithm that measures your website’s overall domain authority.

And it works similarly for AI search engines too.

But here’s the catch…

Not all backlinks are created equal.

Getting a single backlink from a trusted, high-authority, and relevant website can have a significantly greater impact than 10 backlinks from irrelevant, low-authority sites.

Link building is all about quality over quantity. Google and LLMs want to see backlinks from sites they already trust. Those "votes" matter way more than backlinks from small, low-authority sites.

The bottom line is that backlinks create the trust that Google needs to see in order to rank your content. Without them, you’re fighting an uphill battle to reach those first page rankings.

9 Benefits of Building Backlinks

Now you understand how link building works.

Here are the 9 biggest benefits of link building you need to know before you start.

1. Higher Search Rankings

This is the big one…

Backlinks are one of the most important Google ranking factors.

Check out these recent case studies from our link building clients:

And this one:

This client saw massive growth:

Crazy, right?

Backlinko's analysis of 11.8 million search results found that a site's backlink profile had the strongest correlation to high ranking positions in the SERPs.

Quality backlinks = higher rankings.

But the relationship isn’t exactly linear. As I mentioned before, one quality link from an industry-relevant, authoritative publication can outweigh dozens of backlinks from low-authority sites.

The key here is relevance.

A backlink from TechCrunch talking about a SaaS tool makes sense. But a backlink from a small lifestyle blog doesn’t.

Google needs to be able to see the relevance from the linked page to the content on your website.

That relevance is what helps boost rankings for specific target keywords.

Why?

Think about it from the search engine’s perspective…

You can’t just place a link on any website you want because you don’t own them. It’s one of the few parts of SEO that you can’t directly control yourself.

That’s why Google and AI LLMs put so much weight on backlinks as a ranking factor.

Links come from having linkworthy content. If you offer great content, you’ll naturally attract backlinks, and Google can confidently promote your rankings.

If you want to rank higher in the Google search results and get recommended by AI more, you need to build quality links from trusted sites. It’s that simple.

2. Increased Organic Traffic

If you have higher search rankings, you’ll get more organic traffic.

That’s just the simple maths.

But the exact position you rank in significantly determines the amount of organic traffic you get.

Here’s what I mean:

99% of people never click to page 2. If you're not ranking on page 1 of Google, your site is basically invisible.

But the ranking position on page 1 also determines how much organic traffic you get:

As you can see, ranking position 1 gets about 27% of all organic traffic.

If you increase your rankings from position 5 to position 1, you can 4x your organic traffic.

Crazy, right?

And the difference between those two ranking positions is often just a handful of quality backlinks. That’s a big benefit of link building!

3. Referral Traffic

Relevant backlinks don’t just increase your organic traffic…

They also send referral traffic.

What’s referral traffic?

It’s when someone clicks on a link and moves from one site to another site. If you get a backlink from a website, it creates a direct tunnel from that site to yours.

That’s what referral traffic is.

Referral traffic is pre-qualified. You've been endorsed on another site, and the visitor is already interested in the topic. They're reading content that is directly related to your niche and industry.

That usually results in higher engagement rates with your content, lower bounce rates, and even better conversion potential than cold traffic.

Over the last 12 months alone, I’ve received 19,102 visitors from link referral traffic alone:

And over 81% of them were engaged sessions, which placed them at the 5th largest provider of traffic to my website:

Cool, right?

But remember that relevance is important.

If the backlink is from a relevant, high-authority site, the referral traffic will generally be higher quality too. And high-traffic industry blogs can send thousands of targeted visitors to your site every month.

That’s the exact kind of traffic you want!

4. Faster Domain Authority Growth

How do you know what keywords you can target?

The reality is that competitive keywords require more domain authority. Without strong site authority, it’s almost impossible to rank for those high-value keywords that drive real leads and conversions.

Domain authority isn’t a Google metric.

It’s a proxy metric used in the SEO industry that closely correlates to the type and number of keywords your site can rank for.

And different tools have different authority metrics:

Ahrefs - Domain Rating
Moz - Domain Authority
Semrush - Authority Score
Majestic - Trust Flow

The authority metric that I use the most is Domain Rating from Ahrefs. I’ve found it to be the most reliable metric to measure the authority of both my site and client sites.

It’s also considered the best metric for link building. But it doesn’t matter which one you use as long as it’s consistent.

Here’s what you need to keep in mind…

High domain authority means:

– New content ranks faster
– You can target more competitive keywords
– Other websites are more willing to link to you
– Clients, partners, and site visitors view you as more authoritative
– You get referenced more by LLMs and AI search engines

The truth is that authority is more than just a fancy metric that sounds good.

It has a lot of practical value when shaping your overall SEO and link building strategy. And building more quality, high-authority links is the only real way to increase your overall domain authority.

5. Brand Building And Recognition

Link building significantly increases your brand authority with:

• Google
• AI search engines
• LLMs
• Your audience

Let me explain:

When your audience sees your brand mentioned in other industry publications, sites, and blogs, they trust you more.

Think of it like a trust cycle:

Your audience trusts the industry sites
       ↓
The industry sites trust you
       ↓
You build more trust with your audience

The reason this matters is that brand mentions act as social proof. When a respected industry website links to you as an expert or sources your content, it’s a form of recognition that elevates your brand.

And the best part?

It works the same for Google and LLMs.

The more consistently they see your brand mentioned across trusted websites and publications, the more trust they have in you.

That leads to higher rankings, references in Google AI Overviews, and recommendations in AI answers.

You see, link building doesn’t just boost SEO results. It builds the reputation and recognition of your brand across the internet. Even if a reader doesn’t click the link now, they will recognise your brand later.

That should be a primary goal of any serious business!

6. AI Search Visibility

If you didn’t know…

AI search is taking the SEO world by storm. While traditional Google search still has over a 90% market share, AI search engines like ChatGPT and Perplexity are starting to take their slice.

The common complaint at the moment is “AI doesn’t send as much organic traffic as Google does“. And yeah, that’s true.

But don’t listen to the complainers. Because SEO pros can see the huge upside of being mentioned in AI responses.

Let me explain:

57% of consumers now use AI to shop. That's over half!
And it's only going to increase.

But it gets better than that…

AI traffic converts 4.4x better than traditional organic search traffic does. In other words, AI search traffic is up to four times more valuable than Google traffic.

The bottom line is that people trust AI recommendations.

So getting mentioned, sourced, and recommended in AI search engines and LLMs should be an emerging priority for you.

Link building done in the right way is a sure-fire way to build quality brand signals, which is a significant part of being trusted by LLMs like ChatGPT, Perplexity, Claude, and Gemini.

7. Better Indexing And Crawlability

Before your site gets ranked in Google…

…it needs to be crawled and indexed.

And despite what you’ve been told, Google doesn’t crawl all pages equally.

The truth is that it costs money for Google to crawl the web, and by default, they apply what’s called a “crawl budget” to each website.

Crawl budget = the amount of processing power Google is willing to spend to crawl your site. The higher the crawl budget, the more often your site will get crawled.

Now consider that there are over 400+ million maintained websites worldwide with billions of web pages. Google doesn’t have the resources to crawl all websites all the time.

How do they solve this problem?

They prioritise more established websites with higher authority, traffic, and engagement.

This is where backlinks come in:

• They increase your website’s authority, which influences crawl priority
• They help Google discover your pages more regularly through links

Think about it…

Backlinks create more pathways for Googlebot to get to your site while also passing link equity, which increases authority. The result is faster indexing for new pages and more regular crawls from Google.

This is especially important for:

– New websites that are still building authority
– Large sites with thousands of pages
– News publications with time-sensitive information
– Websites where content is regularly updated
– Deep pages that aren’t naturally linked from your homepage

Backlinks force Google to sit up and take notice of your site – leading to higher crawl rates and faster indexing.

Who doesn’t want that, right?

8. Long-Term Compounding Value

Here’s what makes link building so powerful.

Each link compounds over time.

That guest post link you placed 6 months ago is still passing authority and building trust with Google today. A link insert from 1 year ago is still working for you right now.

How many other marketing strategies can make that claim?

And it doesn’t stop there…

The more quality links you build, the stronger your site authority becomes. And as your authority grows, each new link adds even more impact, solidifying your rankings for high-value keywords.

That’s the long-term compounding value of link building.

Now compare this to other traffic sources like paid ads.

Not only do you have to pay for every click, but the moment you stop paying, the traffic stops as well. If that’s your only source, you’re stuck in the pay-to-play game forever.

But links? They compound together to deliver long-term value that continues to work for you, only gaining momentum with each new link you build.

That’s a pretty massive benefit!

9. Competitive Advantage

Here’s the thing most businesses miss about link building…

Link building creates a moat around your business that is not easily replicated by your competitors.

If you’ve spent the last year building 5-10 high-quality links per month, competitors can’t just catch up next month. They essentially need to put in the same time and effort into link building as you did.

That’s why so many businesses and website owners invest in link building.

It creates a competitive advantage that’s not easily taken away. The more quality links you build, the harder it becomes for anyone to get ahead of you in the search results.

And the faster you get started, the faster you’ll create that competitive advantage.

You Need To Understand This About Link Building

Backlinks are like fuel to your SEO engine.
But you still need the engine.

What does that really mean?

Link building works best when you combine it with a strong technical SEO foundation and great content that deserves to rank.

You can build hundreds of quality backlinks, but if your site is slow, has broken pages and your content is thin, the links won’t be as effective.

The good news is that you directly control both the quality of your content and technical SEO, like website load speed. And you can improve them while you build links.

When you do both, that’s when you can see explosive results.

Wrapping It Up

So there you have it.

The 9 primary benefits of link building.

Link building isn’t just about increasing rankings; it’s about driving long-term organic traffic growth and value.

And every link you build compounds together to boost your SEO results and create a competitive advantage that isn’t easily taken away. Plus, you’re positioning your business now to take advantage of AI search as it continues to grow in the future.

That’s a win-win.

Businesses, brands, and websites that invest in link building consistently outperform those that don’t. The results speak for themselves.

But the key is to be consistent.

Frequently Asked Questions

How important are backlinks for SEO in 2026?

Backlinks remain very important for SEO in 2026. They act as votes of trust that build your domain authority and website reputation online.

But the focus has shifted from quantity to quality links. This leads to higher rankings, increased organic traffic, and better visibility in AI search engines.

How many backlinks do I need to rank?

There is no magic number for how many backlinks you need to rank.

It depends on your website authority, competition, and the keyword difficulty.

Low competition keywords might need just 10-30 high-quality links to rank. Higher-competition keywords can require 100+ backlinks. The key is to see how many links your competitors have and then build enough links to compete.

How long does it take to see results from link building?

You can expect to see meaningful results from link building within 3-12 months.

Most LinksThatRank clients see some initial movement within just 2-6 weeks of consistently building links. Google needs time to crawl, index, and evaluate each new backlink before you’ll see changes. That timeline depends on your industry competition, backlink quality, and existing website authority.

Consistent link building is the best way to get steady organic traffic increases, even through algorithm updates.

Do nofollow links have any value?

Yes, nofollow links do have value even though they don’t pass link equity like dofollow links.

Nofollow links increase brand visibility, drive referral traffic, and build authority signals for LLMs like ChatGPT, Perplexity, Claude, and Gemini. Nofollow links from high-authority sites and large publications can also lead to natural dofollow links from other sites over time.

Nofollow links are not the preferred type of link, but they are a natural part of your backlink profile.

What’s more important – link quality or quantity?

Link quality is significantly more important than quantity for SEO.

One high-quality link from an authoritative, relevant site can outperform dozens of low-quality, low-authority links. Low-quality links can even be harmful to your SEO, triggering Google penalties.

Focus on earning and building consistent, high-quality, natural backlinks from trusted sources rather than chasing large volumes of links.
