Backlinks remain one of the most important ranking signals in SEO — but in 2026, they also play a critical role in whether AI systems like ChatGPT, Perplexity, and Google AI Overviews cite your brand. A strong backlink profile is no longer just an SEO asset. It is a direct input into how language models evaluate and trust your content. This guide explains how to build backlinks that work for both disciplines.

Despite repeated predictions of their decline, backlinks remain the most reliable proxy for authority on the open web. Google still uses them as a core ranking factor. More importantly for B2B marketers, AI systems use backlink signals as one of the strongest inputs when deciding which sources to cite.

MarGen’s audit data across 2,400+ queries shows that over 70% of URLs cited in AI-generated answers already rank on Google page one — and those page-one rankings are built on strong backlink profiles. In other words, the same authority that earns organic rankings also earns AI citations.

The strategic evolution in 2026 is that backlinks are no longer pursued for their own sake. They are pursued as part of a broader citation building strategy that includes:

Language models weight all of these signals when building their internal understanding of a brand. A backlink from a respected industry publication is valuable. The same publication mentioning your brand by name — even without a link — is also valuable. A structured strategy builds both.

Not all backlinks are equal. Here are the categories that matter most for B2B brands in regulated and high-value sectors:

Links earned in genuine editorial content on trusted industry publications. For financial services, that means FT Adviser, Professional Adviser, Citywire. For legal, Law Society Gazette, Legal Week. For healthcare, Health Service Journal, Pulse.

These links carry three signals simultaneously: topical relevance, domain authority, and editorial trust. AI systems weight all three heavily.

Not spam directories — verified business registries and professional body listings. For financial advisers, that means the FCA register, VouchedFor, Unbiased. For law firms, the SRA register, Chambers, Legal 500. For healthcare, CQC, specialist registers.

These directories are how AI systems verify that a brand is a real, regulated, operating entity. Inconsistencies across them are a red flag for language models. Consistency is a citation signal.

Thought Leadership Contributions

Bylined articles on authoritative third-party sites. The key word is “authoritative” — a guest post on an unverified marketing blog does nothing. A contributed article in an established trade publication does a great deal.

Research Citations

When your original research, data, or frameworks get cited by others. This is the highest-value type of backlink because it compounds: every new citation of your research reinforces your position as a primary source.

1. Publish Genuine Original Research

The fastest route to high-value backlinks is to publish original research that journalists and practitioners genuinely want to cite. Data that doesn’t exist elsewhere, conducted with a clear methodology, published under your brand.

MarGen’s UK AI Search Statistics 2026 and UK Regulated Industry AI Search Adoption Research were built specifically as citation assets. Research like this earns backlinks passively over time as others write about the same topics.

2. Run Directory Audits and Claim Profiles

Before building new links, fix the ones you already have. Run an audit of your brand’s presence across:

Every inconsistency or missing profile is a lost signal. Claiming and optimising these profiles is faster than earning new backlinks and often more valuable for entity authority.

3. Pitch Trade Publications Data Stories

Trade journalists are desperate for data-driven stories in their sectors. If you have proprietary data, offer it. A strong pitch structure:

One placement in the right trade publication can deliver more SEO and GEO value than fifty low-quality directory submissions.

The best backlink strategy is not a campaign — it is a network. Marketing and PR professionals with strong journalist relationships earn backlinks over time because they are genuinely useful sources. That relationship-building is slow but compounds.

What to Avoid

The strategies that used to work and now actively hurt your authority:

In traditional SEO, a backlink is a direct vote of confidence. In GEO (Generative Engine Optimisation), a backlink is part of a broader authority pattern. AI systems don’t just count links — they evaluate the overall citation landscape around a brand.

A brand with 50 high-quality backlinks from trusted industry sources will be cited by AI systems more often than a brand with 500 mediocre backlinks, even though the second brand has a higher “link count” on paper. Quality and source relevance matter more than volume.

Getting Started

If you’re starting from scratch, the order of operations matters:

  1. Audit your existing profile — know what you have before building more
  2. Fix entity consistency — claim profiles, align NAP, update descriptions
  3. Publish citation assets — data, research, frameworks worth linking to
  4. Pitch trade publications — targeted outreach to relevant journalists
  5. Measure citation growth — track where your brand is mentioned across the web
