The link-building advice of 2015 reads, in 2026, like a manual for a different internet. Guest posts on low-quality blogs, directory submissions, blog comment links — Google has been ignoring or actively penalising most of this for nearly a decade. The principles of how good links are earned have not changed. The execution has.
What still works
Original research
If you publish a number nobody else has, journalists and other operators will link to it. State of X surveys, benchmarks, internal data presented honestly. The link economy hasn't found a substitute for "I measured this and here's what I found."
Useful tools and calculators
A free calculator that does one job well — a colour-contrast checker, a JSON-to-CSV converter, a tax-aware mortgage tool — accumulates links indefinitely because it is genuinely useful and easy to reference. The bar is "would I bookmark this myself."
Definitive guides
The "best resource on the internet for X" page. These take months to write, are kept updated, and earn links the way a textbook earns citations. Most blogs aren't willing to invest in one. The ones that are see compounding returns.
Being interviewed, podcasted, quoted
Other people's audiences. Show up on someone else's show with something worth saying and the link comes free. Difficult to scale; very effective when it lands.
What doesn't work anymore
- Mass guest posting. Most accepting sites are link farms or AI-generated content mills. Google knows.
- Buying links. Detection is reasonable and the penalty cost is real. Even if it appears to work short-term, it digs a hole you have to pay to climb out of.
- Reciprocal link schemes. "I'll link to you if you link to me" — devalued for a decade. Move on.
- HARO-style spam. Help A Reporter Out is now flooded with low-quality pitches. The original signal got buried. Real journalists use other channels.
The new wrinkle: LLM citations
In 2026 a meaningful share of discovery happens inside AI assistants rather than search engines. Whether your content gets cited by a large model when someone asks about your topic is the new "page one of Google" — and the optimisation for it is somewhere between SEO and trust signals.
What we observe:
- Content that is structured, factual, and clearly attributed is more likely to be cited.
- Brand recognition outside the search engine matters more, not less.
- Schema.org markup helps, in the same way it helps Google.
The framing we use with clients
Stop thinking about "link building" as a discrete activity. Think about being worth linking to. If your site is the best resource on a given topic, links will follow without manual outreach. If your site is the fifth-best, no amount of outreach campaigns will change that durably.
The work of building authority and the work of "doing SEO" have converged. That is mostly good news for honest businesses. It is bad news for people whose business model assumed a market for cheap, manipulated authority.
