Link building earns links from other sites to yours, the votes of confidence that still drive ranking authority. The links that count are editorial (given, not bought), relevant, and from trusted sites. The best tactics in 2026: digital PR, guest contributions, resource and broken-link outreach. Avoid link schemes, PBNs and paid follow links, they risk a penalty. In AI search, unlinked brand mentions matter too. This is the one-page checklist.
The link types that matter
| Type | What it is | SEO value |
|---|---|---|
| Editorial link | A site links to you because your content earned it | Highest. The links Google trusts most |
| Dofollow | Passes ranking authority (the default) | Full link equity |
| Nofollow / UGC / sponsored | Tagged so they pass little or no equity | Low for ranking, still useful for traffic and brand |
| Built link | You placed it (guest post, directory, profile) | Varies. Fine if relevant and editorial-quality |
The link building tactics, ranked by value
| Tactic | How it works | Effort vs value |
|---|---|---|
| Digital PR | Newsworthy data or stories that earn press coverage and links | High effort, highest value. See the digital PR cheatsheet |
| Guest contributions | Expert articles on relevant, reputable sites | Medium effort, good value when the site is genuinely relevant |
| Resource page outreach | Get listed on curated resource and links pages | Low effort, steady value |
| Broken link building | Find dead links, offer your page as the replacement | Medium effort, good value |
| Unlinked mentions | Find brand mentions with no link, request one | Low effort, quick wins |
What makes a good link
| Factor | Why it matters |
|---|---|
| Relevance | A link from an on-topic site counts far more than an unrelated one |
| Authority | Links from trusted, established domains carry more weight |
| Placement | In-content editorial links beat footer or sidebar links |
| Anchor text | Natural, varied anchors. Over-optimised exact-match anchors look manipulative |
What to avoid
- Paid follow links. Buying links that pass equity breaches Google guidelines and risks a penalty.
- PBNs and link schemes. Private blog networks get detected and devalued or penalised.
- Mass low-quality directories. Irrelevant bulk links add risk, not authority.
- Over-optimised anchors. Exact-match anchor text at scale is a classic spam signal.
In AI search, unlinked brand mentions correlate strongly with citations, so PR that earns mentions pays off twice. See the AI SEO cheatsheet and SEO fundamentals.
Frequently asked questions
What is link building in SEO?
Link building is earning links from other websites to yours. Each editorial link acts as a vote of confidence that helps search engines judge your authority and trust. Relevant links from reputable sites are a core ranking signal.
What is the best link building tactic?
Digital PR: creating newsworthy data, research or stories that journalists want to cover and link to. It earns the most relevant, authoritative, editorial links, the kind Google trusts most, and it doubles as brand mentions for AI search.
Are paid links against Google guidelines?
Paid links that pass ranking authority breach Google guidelines and risk a penalty. Paid links are allowed only when tagged nofollow or sponsored so they do not pass equity. When in doubt, do not buy follow links.
Do backlinks still matter in 2026?
Yes, links remain a core authority signal for Google. For AI search, unlinked brand mentions matter as much or more, so a modern link strategy earns both links and mentions through digital PR.
