Link Building in 2025: What Still Works and What’s Spam

ByErwee Coetzee

Link building has long been one of the most debated topics in SEO. For years, marketers chased backlinks as the ultimate ranking signal. But in 2025 — especially after Google’s August Spam Update — the rules of link building have shifted dramatically.

Today, it’s no longer about how many links you can acquire, but about quality, context, and authenticity. For South African businesses, knowing the difference between what works and what Google considers spam is essential to building sustainable rankings.

Why Links Still Matter in 2025

Backlinks remain a critical part of Google’s algorithm because they act as votes of trust. When reputable websites link to yours, it signals authority, relevance, and credibility.

However, not all links are created equal. Links gained through manipulation or automation are now more easily detected — and penalised.

The August 2025 Spam Update: A Turning Point

Google’s August Spam Update, its first since December 2024, reinforced a clear message:

  • Links must be earned, not bought or manufactured.
  • Tactics like link farms, doorway sites, and programmatic guest posting are being targeted.
  • Websites engaging in manipulative linking risk sudden ranking drops or de-indexing.

For South African companies, this means any shortcut link strategies could harm long-term visibility.

What Still Works in 2025

1. Editorial Backlinks from Authority Sites

Links from respected publications, industry blogs, or news outlets carry strong weight. Example: a Cape Town tourism company featured in a Travel & Leisure article.

2. Local Partnerships & Mentions

Collaborations with local chambers of commerce, directories, or event sponsorships create genuine, location-relevant backlinks.

3. Content Worth Linking To

High-quality content such as guides, research, or case studies naturally attract links. For example:

  • A law firm publishing a “Small Business Legal Guide in South Africa.”
  • A jeweller showcasing “The History of Diamonds in Cape Town.”

4. Digital PR & Storytelling

Unique campaigns or brand stories picked up by local or international media earn authoritative links.

5. Resource & Tool Pages

Offering free tools, calculators, or templates encourages organic linking.

What’s Spam in 2025

  • ❌ Paid Links Without Disclosure: Buying links to manipulate rankings remains a violation.
  • ❌ Link Farms & PBNs: Networks built solely to pass link equity are easily detected.
  • ❌ Automated Guest Posts: Large-scale, low-quality posting for backlinks is penalised.
  • ❌ Irrelevant Links: Backlinks from sites unrelated to your industry or region offer little value.
  • ❌ Over-Optimised Anchor Text: Repetitive, keyword-stuffed anchors are a red flag.

The South African Context

For South African businesses, link building should focus on local authority and relevance:

  • Local media outlets (News24, IOL, Bizcommunity).
  • Tourism boards and regional business associations.
  • South African blogs and influencers relevant to your niche.
  • High-quality directories like Yellow Pages or Brabys.

These not only build links but also strengthen brand recognition within local markets.

Action Plan: Sustainable Link Building in 2025

  • ✅ Audit existing backlinks and remove or disavow toxic links.
  • ✅ Prioritise quality over quantity — one link from a trusted source is worth more than 100 spammy links.
  • ✅ Invest in content marketing that naturally attracts backlinks.
  • ✅ Build local partnerships to strengthen regional visibility.
  • ✅ Monitor link growth in Google Search Console to detect suspicious patterns.
