Backlinks Importance: Why Backlinks Are Critical for SEO in 2026

The importance of backlinks has only grown as search becomes more competitive.

Today, the average backlink costs more than $300, and brands invest thousands of dollars on them every month. But backlinks are no longer just about rankings – they influence trust, visibility, referral traffic, and even AI search citations.

Understanding backlinks importance means understanding how Google evaluates credibility. Links act as third-party endorsements, helping search engines determine which websites deserve to rank.

In this guide, we’ll break down the real importance of backlinks, from rankings and traffic to revenue impact, and show you how to evaluate link quality in 2026.

Key takeaways

• Backlinks remain one of Google’s strongest ranking signals in 2026. Despite constant algorithm updates, high-quality inbound links continue to correlate with higher rankings and organic traffic.

• Quality outweighs quantity. A few contextual links from relevant, authoritative websites will outperform dozens of low-quality placements.

• Relevance is non-negotiable. Links from websites within your niche carry significantly more weight than generic placements on unrelated domains.

• Backlinks drive more than rankings. They influence referral traffic, brand trust, lead generation, and increasingly, AI search citations.

• Link placement matters. Natural anchor text, contextual integration, and positioning higher in the article increase link value.

• Website metrics are indicators, not guarantees. Domain Rating, Domain Authority, and organic traffic help evaluate quality – but manual review is still essential.

• Bad backlinks can harm performance. Low-quality directories, spammy pages, irrelevant placements, and manipulative links can drain budget and reduce visibility.

• Backlinks are long-term assets. A single high-authority contextual link can drive qualified traffic and revenue for months or even years.

What are backlinks?

Backlinks are links that other websites give to your website. When someone writes about a certain topic and adds a link to your post or home page, this is a backlink. When websites give out links to your web pages, they’re sending a signal of trust. It means that you’re an expert on this topic and that when someone searches for it in search engines, your website should be placed higher.

The more authoritative the website that is giving you a link, the more valuable this backlink is for your digital marketing and sales efforts.

You wouldn’t be wrong to assume that more backlinks means better SEO performance. However, building backlinks is all about quality, rather than quantity. You want to build quality backlinks that move the needle, rather than low-quality ones from spammy websites.

But more on how to identify great backlinks later.

Why are backlinks important for SEO?

Google’s algorithms have been changing for decades now, and they release a new one every other month or so. An algorithm is a set of rules that tells website managers and business owners what they need to do to rank well in search results and get organic traffic from Google. Throughout the years, one of the strongest ranking signals for websites has been backlinks.

Backlinks are a strong ranking signal

Google themselves have stated multiple times throughout the years that having relevant links helps with search engine rankings. If a website has more good backlinks (and quality content, of course), it’s going to perform better in the SERPs compared to websites with similar content but no backlinks.

Independent research by SEO powerhouses such as Backlinko have also confirmed that backlinks are an extremely important vote of confidence that help websites get better rankings.

Over the years, Google has tried to downplay the importance of backlinks for search engine performance, but independent research has shown that a strong backlink profile correlates with higher rankings.

Inbound links correlate with higher traffic

It doesn’t take a rocket scientist to figure out that with higher rankings, you get more clicks. While trustworthiness and better positions in search rankings are nice to have, most site owners care about other things. Higher website traffic means more people coming to your website, and that means potentially more purchases.

This is why almost every SEO strategy puts backlinks at its core – coupled with high quality content, it’s one of the few marketing tactics that brings a solid return on investment.

Backlinks can bring referral traffic

Imagine you run a small marketing app and you get a backlink from a website like Hubspot. Website links like these do not only impact rankings because not all backlinks are created equal.

When you get a high-quality link from a relevant page, you not only get a bump in organic search, but you also get referral traffic. In other words, people head from the website where the link was placed to your website. This makes links from authority websites especially valuable for your marketing and sales metrics.

This illustrates a second layer of backlinks importance – acquisition value. High-authority placements don’t just influence rankings; they can generate sustained referral traffic from audiences already aligned with your product or service.

In many cases, a single contextual link from a trusted publication can drive qualified leads months or even years after it goes live.

How to recognize good backlinks

If you’re just starting with your link building strategy, you may be thinking that just about any backlink to your website is going to make a difference in your performance in search engine results pages. But that couldn’t be further from the truth. Here are a few tips for website owners to help recognize high-quality links.

These links come from relevant websites

Imagine you have a store that sells baby food and you need a certain number of backlinks for your pages to start ranking. You hire an agency, they do some outreach and you see an influx of links… From camping gear websites.

While these may be authoritative websites in their own domain, the truth is that they won’t make much of an impact for you. Google considers links as ranking factors only when they come from relevant websites.

In this case, getting links from mom blogs and lifestyle magazines would be more relevant and would contribute to your SEO success.

And even when you find a website that fits your niche, you want to make sure that it covers the same topics consistently and that there are no random spammy topics around casinos, drugs, adult content and other things that could put you in bad company.

The website metrics are solid

The quality of a website can be measured in several ways. It’s one of the easiest ways to tell if a link is good, but it’s not the definite, end-all answer. However, this is what you should check for each website:

• Domain rating: a metric by the SEO tool Ahrefs, on a range from 0 to 99
• Domain authority: a metric by Moz, on a range from 0 to 99
• Website organic traffic: you should aim to get links from websites with higher search traffic, showing that Google likes those sites enough to send them traffic
• The number of referring domains and backlinks: the website you’re getting links from should have quality backlinks itself

An example of website metrics as seen in Ahrefs

These are excellent starting points, but you should still do a manual check for the quality of the website as well. Sometimes, a website can be a PBN (private blogger network) that has amazing stats but is still not a good target to get links from.

The link placement is natural

For search engine optimization efforts to pay off, the links you build have to look natural and not forced into the content. This means that the link inserted should flow with the surrounding content and not feel like you spilled a can of beans on top of a cake.

For example, this is a natural placement:

As a mom, I’m used to shopping for most of my baby supplies alone. Buying baby food and clothes is something I do either alone or with my friends.

And this is an example of an unnatural placement:

It’s a great feeling to have your household stocked up and my pantry is filled to the brim with canned food and ready-to-eat meals in case of emergencies. Buying baby food is a necessity too.

Both are in the context of food, but only one of them connects the link with the surrounding text. With this in mind, here are some great ways to tell if link placement is natural:

• The anchor text (the text of the link) has to be a natural phrase
• The link should lead to a relevant page on your website with the right content (e.g. a page for buying baby food for our example)
• The link should ideally be dofollow (but nofollow links are acceptable too)
• It should be in a nice place in the article, preferably close to the top and not in the conclusion

With these guidelines, you should hopefully be able to find quality websites and get incoming links that boost your performance despite the ever-changing search engine algorithms.

How to recognize bad backlinks?

Bad links do more harm than good and instead of boosting your performance in Google search results, they drain your marketing budget and may even lower your rankings. Here are some of the tell-tale signs of a bad link.

1. The link comes from a general type of website – e.g. news, lifestyle, magazine websites. The wider the range of topics, the smaller the chances that it’s a valuable link
2. The page with your link has tons of other external links on it – this could be a case that it’s a guest post with lots of links in it. In any case, it’s not ideal to share the real estate on a page with many other websites, as this means the link is not as valuable
3. The link is crammed in the conclusion – someone put it there so it does not affect the rest of the text. These links have less value and probably will not drive many clicks or improve your website’s ranking
4. Directory links – anyone can get directory links and as such, their value is not that great
5. The content is low quality – if the post that you’re getting a link from reads like it was written by a 5-year-old child from rural China, there are no types of backlinks that could be good from that content
6. The domain rating of the website is low – you can check this in a tool such as SEMrush or Ahrefs. You should target websites with higher metrics
7. The link is no-follow – sometimes, the webmaster can give the link a nofollow attribute to tell search engines to “ignore” it. Ideally, you should pursue dofollow links most of the time

Backlinks importance beyond rankings

While rankings are the most visible outcome, backlinks importance extends further.

Strong backlink profiles can:

• Accelerate content indexation

• Strengthen brand authority

• Increase partnership opportunities

• Improve AI search citation likelihood

As search evolves toward entity-based evaluation, links function less like isolated signals and more like trust relationships between brands.

Frequently asked questions

Are backlinks still important for SEO in 2026?

Yes. Backlinks remain one of the strongest ranking factors in Google’s algorithm. While content quality and user experience matter more than ever, links continue to serve as third-party validation of authority and trust.

How many backlinks do I need to rank?

There is no fixed number. What matters is the quality, relevance, and authority of the links compared to your competitors. In many cases, fewer high-quality backlinks outperform a large volume of weak ones.

Do nofollow links have value?

Yes, although they do not directly pass ranking authority in the traditional sense. Nofollow links can still generate referral traffic, build brand awareness, diversify your link profile, and support natural link acquisition.

Can bad backlinks hurt my rankings?

Yes. Spammy, irrelevant, or manipulative backlinks can negatively impact your website’s performance. It’s important to regularly audit your backlink profile and disavow harmful links when necessary.

How do I know if a backlink is high quality?

A strong backlink typically comes from:

• A relevant website within your niche

• A page with solid organic traffic

• A domain with strong authority metrics

• Contextual, natural anchor text

• A well-written, high-quality article

Are backlinks more important than content?

No. Backlinks amplify good content, but they cannot compensate for poor content. The most effective SEO strategies combine authoritative backlinks with genuinely useful, high-quality pages.

Do backlinks help with AI search and generative engines?

Increasingly, yes. As AI-powered search engines rely on trusted sources and entity signals, strong backlink profiles contribute to brand credibility and increase the likelihood of being cited.

Conclusion

Until Google changes their minds (which doesn’t seem likely any time soon), backlinks are one of the strongest signals for a website to rank well in search results. There is a catch though – your links have to be built naturally, from high-quality domains and from relevant pages.
