AI is rewriting the rules of search. Backlinks were the backbone of any SEO strategy for years, serving as an authority signal that directly influenced a website’s ranking.

But, AI is transforming how people find information, with Google AI Overviews, Perplexity, and ChatGPT consistently growing in popularity.

The question many people are asking is: Do backlinks still matter? The answer is yes. But there are some key changes to be aware of. We’ll explore them in this post.

TL;DR: Backlinks Still Matter

  • Backlinks still matter in the age of AI search. But quality, context, and variety now count more than volume.

  • AI models like Google AI Overviews, Perplexity, and ChatGPT are trained on web data. They learn which sources are trusted and cited, which defines whether they use them for AI-generated answers. A strong backlink profile from high-authority publications can enhance your traditional rankings and AI visibility.

  • AI tools also recognise unlinked brand mentions across podcasts, news coverage, and industry reports — broadening what “link building” really means. A winning link-building strategy combines high-quality backlinks, topical authority, original content, digital PR, and a clean link profile.

The Role of Traditional Link Building

Traditional SEO is heavily reliant on backlinks because they signal a website’s authority and trustworthiness. For example, Google’s PageRank criteria clearly states that when high authority sites link to content, it must be high quality and worth higher ranking positions:

Marketers responded to this by focusing heavily on link-building strategies, including digital PR, guest posts, and utilising broken links. Of course, there were also black hat techniques that Google aimed to address.

Backlinks are still a core ranking factor in any SEO strategy. But the rise of AI search has added new layers of complexity to outreach.

How AI Search Engines Actually Work

AI-powered search tools work differently from traditional search engines. While Google and Bing display a list of relevant results, LLMs provide answers to questions and cite sources.

So, when it comes to creating content for LLMs, you’re not focusing on making sure your pages rank; you’re focusing on ensuring that it becomes one of the cited sources.

We can see the core differences between traditional SEO and AI search for a simple query like “Does my business need SEO?”

How Do High-Quality Backlinks Influence AI Search Visibility?

AI models are trained on vast amounts of data and web content, which directly influences their capabilities and the answers they provide when a user searches.

During training, the LLM learns which sources are frequently referenced and cited, which affects whether it chooses to use your content.

So, if a website has high-quality backlinks from trusted sources, it’s not just more likely to achieve higher rankings; it’s also more likely to appear in AI searches.

Quality Matters More Than Quantity

We all know that high-quality backlinks are worth more than links from low-authority websites. If you have five backlinks from highly respected publications and organisations, both search engines and AI models will view your content as more credible.

It’s also important to remember that AI models are advanced enough to understand context. For example, if a healthcare website has links from peer-reviewed medical journals and the NHS, it’s seen as more trustworthy than a competitor with links from general directories and low authority websites.

However, quality isn’t enough anymore. Variety and context matter for AI search visibility.

Brand Mentions and Unlinked Citations

A high Google ranking often requires a hyperlink, as it passes authority. So, even if your website secured a brand mention from a reputable publication, it was pretty much invisible from an algorithmic standpoint without a hyperlink.

AI visibility doesn’t rely on hyperlinks because the tools process language rather than link graphs. This means that a brand can appear in AI responses through conversational authority.

For example, if your brand is mentioned on a podcast, industry report, through news coverage, or other sources, it can be cited in AI-driven search results without a hyperlink.

However, this doesn’t mean that backlinks aren’t important signals for AI models. This means the definition of outreach now includes mentions and references across platforms and formats.

E-E-A-T

Google’s Experience, Expertise, Authoritativeness, and Trustworthiness (E-E-A-T) signals are integral to how the platforms’ AI Overviews choose sources to feature.

Backlinks play a part in this, as they signal authority and trust. But, content relevance, quality, and the author’s credentials are also part of the equation.

If you have backlinks from high-authority sources, Google naturally views your website as more trustworthy than your competitors’. This directly impacts whether it features you in overviews.

Implementing AI-Related Backlinks into Your SEO Strategy

Backlinks matter for both organic rankings and appearing in AI-generated answers. But it’s not about building more links; it’s about making your content appealing to authoritative publications and focusing on quality.

Here are some tips for implementing backlinks into your AI visibility strategy:

Focus on Topical Authority

It’s tempting to secure backlinks from authoritative domains that aren’t relevant to your niche. However, AI models reward expertise in particular subject matters. Let’s say a financial website wants to increase its authority.

While some publications like BuzzFeed are high-authority, a lower-authority backlink from an industry-relevant publication can be more effective.

AI models are more likely to view you as a valuable source when your website is authoritative within its industry.

Create Quality Content

Links matter, but they’re no substitute for content quality. AI-generated answers look at different sources and are more likely to cite content that offers an original perspective, backs up its claims with data, and is genuinely valuable.

Use Digital PR

Google AI Overviews, ChatGPT, and Perplexity also look at brand mentions. You don’t necessarily need a high raw link volume, because AI tools can find you through citations and references from other websites.

For example, if you sponsor an event within your community, it doesn’t just boost your local SEO strategy; AI models will be able to see local newspapers mentioning your brand, even if they don’t directly link to your website.

Take a Holistic Approach to Visibility

Remember, there are different ways to enhance your AI visibility. Securing mentions in industry-relevant forums, appearing on podcasts, and being cited in academic papers all make you more discoverable for Large Language Models.

Remove Toxic Links

Toxic and spammy links can significantly impact your domain rating. Poor link quality sends negative signals to both search engines and AI models, which limits your ability to appear in AI-generated responses.

Regularly check your backlinks and disavow any low-quality ones.

The Bottom Line

Despite the SEO industry evolving and AI becoming a core factor in any strategy, backlinks still matter. But today it’s more about finding quality links than focusing on quantity. A website with 10 high-authority backlinks will perform better than a site with hundreds of linked pages if those links are spammy.

If you want to succeed in the era of AI, content quality, referring domain diversity, author credibility, and digital PR are key to your brand’s growth.
