What Is Link Building? A Beginner's Guide

Link building is the practice of getting other websites to link to your site. Each of those links — called a backlink — acts as a signal to search engines that your content is worth referencing, which is why link building remains one of the highest-impact parts of SEO.

Link building meaning, in plain terms

Think of the web as a network of recommendations. When Site A links to Site B, it's effectively vouching for Site B's content. Search engines read this at scale: pages with more (and better) links pointing at them tend to rank higher, all else being equal.

That's the whole concept behind "what is link building" — it's the deliberate, ongoing process of earning those recommendations rather than hoping they happen on their own.

Why link building affects rankings

Search engines use links as one of their strongest ranking signals for two reasons:

• Links are hard to fake at scale. Getting a genuinely relevant site to link to you usually means your content actually earned it.
• Links carry context. The anchor text and the linking page's topic tell search engines what your page is about, reinforcing your own on-page signals.

Main types of link building

Directory and citation submissions

Submitting your site to relevant, vetted directories. Low effort per link, and a solid foundation layer — this is the method our own service specialises in.

Content-driven link building

Creating something genuinely link-worthy — original research, a free tool, a thorough guide — that other sites reference naturally.

Outreach-based link building

Manually contacting site owners to request a link, a guest post, or a mention, usually in exchange for genuinely useful content.

Web directory link building

A subset of directory submission focused specifically on general and niche web directories, historically one of the earliest link building tactics and still effective when done selectively.

Is link building still worth doing?

Yes — but the bar has risen. A decade ago, volume alone worked. Today, relevance, diversity of referring domains, and a natural pace of link acquisition matter far more than raw link count. Read our full backlink strategy guide for how to plan this properly.
