Why backlinks matter#
Links were the foundation of Google’s original PageRank algorithm, and they’re still a major signal of authority and trust. A page with relevant links from respected sites is more likely to rank than an equally good page with none.
What makes a backlink valuable#
| Factor | Strong link | Weak link |
|---|---|---|
| Relevance | Site in your industry or topic | Unrelated site |
| Authority | Trusted publication with real traffic | New spam blog or link farm |
| Placement | In the body of an article | Sitewide footer or comment |
| Editorial | Given because your content is useful | Paid or exchanged without disclosure |
| Anchor | Natural, descriptive | Over-optimised exact-match keyword |
Safe ways to earn links#
- Create linkable assets: original data, tools, templates, in-depth guides like this SEO Library.
- Digital PR: pitch journalists with expert commentary or newsworthy findings.
- Guest contributions to respected industry publications (for audience, not just the link).
- Unlinked mentions: ask sites that mention your brand to add a link.
- Broken link building: suggest your resource to replace dead links on relevant pages.
- Local links: associations, events, suppliers and local media.
What to avoid#
Buying links that pass ranking signals, large-scale link exchanges, private blog networks and automated link schemes violate Google’s spam policies. Paid or sponsored links should carry rel="sponsored". See nofollow links and anchor text.
