From Links to Citations: Link Building in the AI Era

For over two decades, links have been the backbone of Google’s search results. That principle still holds true, but the game has changed significantly with the advent of AI search. Today, link building isn’t just about pushing a page up into the blue links. It’s just as much about building the credibility that makes large language models like ChatGPT, Perplexity, and Google AI Overviews cite your brand specifically rather than your competitors.

The data clearly shows the shift: Quality and authority trump quantity more than ever. A A study by Semrush of 1,000 domains confirms that high-authority domains are mentioned more frequently in AI-generated responses. But it also shows that small, incremental improvements don’t make a difference. It’s only when you break through a certain authority level that you really start to gain visibility in AI responses.

At InboundCPH, we view link building as an integral part of a modern AI-SEO strategy. Whereas traditional SEO sought out every link for the sake of link juice, modern link building focuses on acquiring the citations and mentions, which creates semantic relevance. It’s about matching the media source from which the link originates and strategically directing potential customers to your business by highlighting your USPs and positive press coverage.

What is link building in 2026?

Link building is the discipline within SEO, where you work specifically to get other websites to mention and link to your own. But in 2026, the definition is broader: It’s no longer just the clickable hyperlink that counts. It’s the mention itself, the citation, and the context in which your brand appears that build the semantic relevance AI models are looking for.

A link acts as a digital recommendation. When a credible media outlet, an industry portal, or an awards website mentions you, it signals to search engines and AI models that your content and brand are valuable, relevant, and trustworthy.

Previously (2010–2020)

Quantity and Link Juice

  • Focus exclusively on clickable dofollow links
  • Mass production based on catalogs and irrelevant blogs
  • The goal was solely to manipulate the rankings
  • Anchor Text Optimization Taken to the Limit
Now (2024–2026)

Semantic Relevance and PR

  • Citations and mentions count as trust signals
  • Media Match: The Context Must Align with Your USPs
  • Attracting real customers, not just bots
  • Repurposing Awards and Positive PR

What makes the perfect link?

Not all links are equally valuable. A link from an established Danish media outlet with high authority and topic-related relevance can have a greater impact than a hundred links from unknown sites. We assess the value of a link or a mention based on five dimensions:

01 — SEMANTIC RELEVANCE

Contextual match

A link only has real value if it makes sense in context and aligns with the medium. If you sell B2B software, a link from an IT publication establishes the right semantic relevance. A link from a lifestyle blog is worthless for the AI’s understanding of your expertise.

02 — AUTHORITY

High domain authority

A link from an established media outlet or a recognized industry portal sends a strong signal to both Google and AI models. The harder the link is to obtain, the more credibility it conveys.

03 — CHANNELING

Attracts real customers

The perfect link is placed where your target audience actually is and is worded to highlight your USPs. It drives not just “link juice,” but real, qualified traffic to your business.

04 — DIVERSITY

Natural Link Profile

A strong backlink profile is diverse: it includes dofollow and nofollow links, links to various subpages, varied anchor texts, and plain brand mentions. AI models reward this natural distribution of mentions.

05 — LANGUAGE

Linguistic and Geographical Match

For a Danish website, links from Danish domains and Danish-language pages are more valuable than those from foreign-language sites. This signals local relevance to the search engine.

What's New in 2026

Semrush data shows that nofollow-links Mentions from high-authority sources have an almost identical positive effect on AI visibility as dofollow links (Spearman: 0.509 vs. 0.504). A mention on a major platform counts, regardless of the link attribute. It is the citation itself and the semantic context that build your “entity” in the language models.

Link Building and AI Search: Why They Go Hand in Hand

AI search engines such as ChatGPT, Perplexity, and Google AI Overviews generate answers by synthesizing information from many sources. When selecting which brands and pages to cite, they prioritize many of the same signals as traditional search: authority, trustworthiness, and expertise (E-E-A-T).

But there is one crucial difference. In traditional search, you’re competing for 10 blue links. In AI-generated answers, you’re competing to be cited as a source, and there’s typically only room for 3–5 citations. This makes strategic link building even more important because:

  • Links from authoritative sources signal to LLMs that your brand is trustworthy
  • Mentions of your brand (even without a link) strengthen your “entity” in the AI models’ knowledge base
  • Diversity in sources and mentions increases the likelihood of being cited
  • A strong link profile correlates with a higher AI Share of Voice

An important nuance: Ahrefs’ analysis of 75,000 brands shows that brand mentions correlate more strongly with AI visibility than backlinks alone (0.664 vs. 0.218). This doesn’t mean that links are irrelevant, but rather that link building in 2026 should be approached more broadly. It’s about building a comprehensive online presence where links, mentions, and citations collectively establish your brand as an authority that AI trusts.

Brand mentions correlate about three times more strongly with AI visibility than backlinks alone.

5 Strategies for Getting High-Quality Backlinks and Citations in 2026

Getting the right links requires an effort that goes beyond the SEO department itself. It’s about leveraging the company’s overall PR and marketing efforts to create semantic relevance.

1

Repurpose Awards and Positive PR

Have you won an industry award, received a certification (such as B Corp), or gotten a great review in a trade publication? Use it proactively. Repurpose this positive coverage by reaching out to partners, industry associations, and local media to get them to mention the award—and link to you. This highlights your USPs and creates incredibly strong, trust-building citations.

2

Create link-worthy content using original data

The most effective way to attract natural links is to publish original data, studies, or in-depth analyses. Journalists and bloggers are constantly looking for sources to back up their claims. If you position yourself as that source, the links will follow. Examples: industry studies, benchmark reports, or annual trend analyses. This approach is particularly effective for B2B companies.

3

Channel-Based Media Matching and Outreach

Identify the platforms, media outlets, and partners that share your target audience. Offer expert commentary, guest articles, or participate in co-marketing initiatives. The goal isn’t just a link, but to place your message somewhere where it actively channels potential customers to your business because the context perfectly matches your core offering.

4

Visual Assets and Infographics

Infographics, charts, and data visualizations are often shared and embedded on other sites. Make sure your visual assets are easy to share and clearly attribute the source. Data shows that image links have a stronger correlation with AI visibility than traditional text links (Pearson: 0.415 vs. 0.334) once you’ve established a basic level of authority.

5

Barley Topical Authority with cluster content

When you cover a topic broadly and in depth with cohesive content (pillar + cluster), you naturally attract links from others who reference your expertise. This also strengthens your internal link structure and sends a clear signal of subject-matter authority to both Google and AI models.

Poor Link Building: What to Avoid

Not all link-building methods are equally effective, and some can actually harm your visibility. Over the years, Google has tightened its grip on manipulative linking practices, and in the AI era, the risk is even greater because AI models place a high value on credibility.

MethodRiskWhy It Doesn't Work
PBN links (Private Blog Networks)High — may result in a manual penaltyGoogle identifies the networks algorithmically. The links have no editorial context.
Bulk purchasing of cheap linksHigh — Unnatural Link ProfileLow authority, no relevance, often in foreign languages. This creates a clear pattern.
Excessive link exchangeModerate — devaluationGoogle views reciprocal links as collusion. The effect is minimal to negative.
Comment and Forum SpamLow (nofollow) but a waste of timeAlmost all of them are nofollow. No contextual relevance. Zero effect on rankings.
Automated link-building programsVery high — algorithmic penaltyThis directly violates Google's guidelines. The pattern is easy to spot.

Would you want this link if Google didn't exist? If the answer is no, the link is probably not worth pursuing.

Link-Building Strategy: How to Get Started

An effective link-building strategy doesn't start with blind outreach. It starts with understanding your starting point and defining what you can realistically achieve with the resources you have available.

STEP 1

Analyze your backlink profile

Use Ahrefs, Semrush, or Moz to analyze your current backlinks: number of referring domains, DR distribution, anchor text variation, and any harmful links. Compare these metrics with those of your 3–5 main competitors.

STEP 2

Identify PR Assets

What awards, reviews, news stories, or unique data do you have on hand that can be repurposed? These are your strongest assets for generating credible citations and mentions in relevant media.

STEP 3

Identify media match

Find the platforms and media where your target audience spends time. Focus your resources on the placements that don’t just provide a link, but can actively drive customers to you by highlighting your USPs.

STEP 4

Execute and measure

Establish a consistent rhythm for outreach and PR activities. Track new referring domains, brand mentions, DR trends, and organic visibility on a monthly basis. Adjust your strategy based on data, not gut feelings.

Anchor Text: The Often-Overlooked Detail

Anchor text is the clickable text that makes up the link itself. Google uses anchor text as an indicator of what the linked page is about. A natural link profile has varied anchor texts:

Anchor Text TypeExample of an exampleRecommended proportion
Brand name“InboundCPH,” “at InboundCPH”30-40%
Generic“Read more here,” “this guide”20-30%
URL/naked link“inboundcph.dk/ai-seo/”10-15%
Exact-match keywords“link-building strategy”5-10%
Partial match“Guide to Effective Link Building”15-20%

An overrepresentation of exact-match anchor texts is one of the clearest signs of manipulation. Keep the distribution natural and varied. In practice, this happens naturally when links come from editorial content, where the journalist or blogger chooses the anchor text themselves.

Link building is an investment in brand authority

It’s tempting to look at your competitors’ total number of links and try to match that number. But that’s a fallacy. Ten links and citations from strong, relevant sources that align with your USPs and drive the right customers will always outperform 1,000 links from irrelevant domains. The right approach is to view link building as a long-term investment in your brand’s digital authority—an authority that pays off in both organic traffic and AI citations.

Frequently asked questions

What is the difference between link building for traditional SEO and AI search?

Traditional SEO focused primarily on dofollow links to pass link juice. In AI search, links, citations, and brand mentions serve as trust signals that tell the language model that your brand is an authority in the field. Semantic relevance and context carry incredible weight for AI models.

Can you buy links to improve your search rankings?

Buying links on closed networks or paying for hidden links violates Google’s guidelines and can result in severe penalties. The correct approach is to invest in digital PR, repurpose awards, and conduct outreach that naturally earns coverage and links. Sponsored articles are legal, but must be labeled as sponsored content.

How long does it take for link building to work?

It depends on your starting point, the competition in the market, and the quality of the links you acquire. Typically, you’ll start to see an impact on visibility after 3–6 months of consistent effort, especially when combined with strong content and technical SEO.

What is Domain Rating (DR), and how high should it be?

Domain Rating is a third-party metric from Ahrefs that estimates a domain’s authority on a scale from 0 to 100. It’s not a number that Google uses directly, but it’s a good guideline. In the Danish context, a link from a site with a DR of 20+ is useful, a DR of 40+ is strong, and a DR of 60+ is exceptional.

What is internal link building, and how does it work?

Internal link building involves strategically linking between pages on your own website. It helps Google understand your site structure and distributes link equity from strong pages to pages that need a boost. A good internal link structure significantly enhances the impact of external link building.
