Link Building in 2026: The Tactics That Still Work (and the Ones That'll Get You Penalised)

Google's link spam updates — particularly the ones rolled out between 2022 and 2025 — have fundamentally changed what link building looks like. Tactics that produced ranking gains three years ago now produce manual penalties or algorithmic suppression. The gap between safe and unsafe link building has never been wider.

Here's an honest, current assessment of what's working, what's risky, and what you should stop immediately.

What still works in 2026

1. Editorial guest posting on genuine publications

Guest posting still works — but the definition of "works" has narrowed significantly. A guest post on a site with genuine organic traffic, real editorial standards, and topical relevance to your industry will move rankings. A guest post on a site that accepts any submission, has no editorial process, and exists primarily to sell links will be discounted or penalise you.

The test we apply before any outreach: does this site appear to have real readers? Are there comments? Is the content genuinely useful? Does it rank for any keywords? Would a real person visit this site to read content? If not, we don't pitch it.

2. Digital PR

Creating genuinely newsworthy content — original research, data studies, surveys, interesting datasets, strong opinion pieces — that journalists and bloggers link to naturally. This produces the highest-authority links available and is completely future-proof because it's exactly what Google wants links to look like.

The investment is higher than other tactics, but a single link from a high-authority publication in your industry can move rankings more than 20 lower-quality links. For businesses with budget for it, digital PR is the highest-ROI link building available.

3. Broken link building

Finding broken external links on high-quality sites in your niche and reaching out to offer your content as a replacement. Clean, white-hat, and welcomed by webmasters because it helps them fix their site. Conversion rates are low but link quality is high when it works.

4. HARO and journalist request platforms

Help A Reporter Out (now Connectively) and similar platforms connect journalists with sources. Responding to relevant requests with genuine expert commentary earns editorial mentions in publications you'd never reach through cold outreach. Requires consistency — most responses don't get used — but the links earned are high-authority and completely natural.

5. Competitor backlink replication

Analysing the backlink profiles of your top-ranking competitors to identify sites linking to them that should also link to you. Systematic, scalable, and produces a clear priority list of outreach targets. Combined with original content creation, this is the backbone of most successful link building campaigns.

What's become risky

Niche edit / link insertion services

Paying to have a link inserted into existing content on third-party sites used to be a reliable tactic. Google's updated guidance explicitly classifies paid link insertions as link schemes. The risk has increased significantly — particularly for sites that have been caught receiving large numbers of these.

We still see some clients with legacy link profiles heavy in niche edits who haven't been penalised. But the risk profile has changed, and we don't build new links this way.

Sponsored content without clear disclosure

Paying for coverage that doesn't include a rel="sponsored" or rel="nofollow" attribute is a violation of Google's guidelines. The links pass less value than they used to, and the pattern of paid placements without disclosure is something Spam Brain can identify at scale.

Stop immediately

Auditing your existing link profile

If you've used an agency in the past that was building links without a clear white-hat methodology, it's worth auditing your profile. Use Ahrefs or SEMrush to export your full backlink list and look for:

• Domains with very high DR but zero organic traffic (classic PBN signal)
• Large volumes of links acquired in a short period
• Links from sites with no topical relevance to your industry
• Identical anchor text across many linking domains
• Links from sites in languages your business doesn't serve

Toxic links should be disavowed via Google's Disavow Tool. The threshold for disavowing has risen — Google now ignores more low-quality links automatically — but a heavily spammy profile still benefits from a clean disavow file.
