Link Building Strategies That Survived Google's Purge in 2025

The shortcuts that don't work anymore

Between 2022 and 2024, Google's spam updates systematically devalued or penalised most of the link-building shortcuts that worked in the previous decade. If you're still paying for any of these, stop:

• Private Blog Networks (PBNs): Networks of sites created purely to pass links. Google has become very good at identifying and algorithmically devaluing these at scale.
• Mass guest posting on low-quality sites: Bulk guest posts on sites with thin content and no real audience are now link spam under Google's policies. Volume without quality is worthless.
• Link exchanges: "I'll link to you if you link to me" - explicit reciprocal link schemes. Google's algorithm detects these patterns.
• Paid links that pass PageRank: Buying "sponsored" links without rel="nofollow" or rel="sponsored" attributes violates Google's guidelines and risks manual penalties.

Five tactics still worth your time

1. Digital PR High ROI

Digital PR means creating content that's genuinely newsworthy - original data, compelling studies, expert commentary on trending topics - and pitching it to journalists and publications. When a publication covers your story, you earn a citation and often a link from a high-authority domain.

For Australian businesses: pitch to The Australian Financial Review, SmartCompany, Australian Startups, and your specific industry trade publications. A well-placed story in a niche AU trade pub can be worth more than ten generic guest posts on low-traffic blogs.

2. Original research and data studies High ROI

Publish something no one else can - original survey data, proprietary analysis, industry benchmarks you've collected. Other content creators will cite and link to you because you're the primary source.

The effort is front-loaded (conducting research, cleaning data, designing the presentation) but the links compound over years as the resource continues to be cited. One strong data study can outperform 100 generic guest posts.

3. Expert quote outreach (HARO-style) Medium ROI

Journalists and bloggers constantly need expert quotes. Services like Help a Reporter Out (HARO), Qwoted, and SourceBottle (AU-focused) connect you with writers actively seeking sources. Respond to relevant queries with genuine insight - not promotional copy - and you'll earn links from the resulting articles.

Volume matters here: responding to 20+ queries per week consistently over 3-6 months builds a real backlink stream. Treat it as a system, not a one-off effort.

4. Broken link building Medium ROI

Find broken external links on authoritative pages in your industry. Contact the page owner to let them know, and suggest your relevant content as a replacement. You're doing them a favour; the link is a natural by-product.

Tools like Ahrefs Site Explorer or Semrush's backlink audit can identify broken links on competitor pages or industry resource lists at scale. It's time-intensive but reliable when executed well.

5. Linkable asset creation High ROI

Build resources that are so useful people link to them naturally: comprehensive guides, free tools, calculators, templates, checklists. The key is targeting content that already attracts links in your space (use Ahrefs' "Best by Links" filter on competitor domains to find proven formats) and creating a definitively better version.

Australian-specific link building tactics

The Australian web has specific properties that create link-building opportunities not available globally:

• AU-specificAustralian business directories: Yellow Pages, True Local, Hotfrog, and industry-specific directories still pass meaningful local authority signals. Many are free. Do these first - they're low-effort and add up.
• AU-specificIndustry associations: Australian industry bodies - the ABA, AICD, ACCI, and dozens of industry-specific groups - often link to member websites. Membership fees double as a link-building investment in high-authority .org.au domains.
• AU-specificState and federal government resources: Business.gov.au and state equivalents maintain supplier and service provider directories. A .gov.au link carries significant authority.
• AU-specificAU university partnerships: Research collaborations, guest lectures, and scholarship sponsorships often come with a .edu.au link from the institution's website. These are among the highest-authority links in the Australian web.

The link building win that costs nothing

Before investing heavily in external link building, audit your internal link structure. Internal links pass authority between your own pages - and most sites use them poorly. Common issues:

• Orphaned pages with no internal links pointing to them (Google struggles to discover and prioritise these)
• Navigation-only links to the homepage, with no contextual links in body content
• Generic anchor text ("click here", "read more") rather than descriptive keyword-rich anchors

A solid internal linking audit often improves rankings on existing pages without acquiring a single new external link. It's the quickest win in the link building toolkit.

The one rule that covers everything

Every link-building tactic that still works in 2025 follows the same rule: earn the link by providing genuine value. A link that someone places because your content helped them is safe and sustainable. A link placed because you paid for it, exchanged for it, or manufactured it is at risk.

Google's direction is clear and has been consistent for years: links as a signal will only matter more for sites that earn them legitimately, and matter less (or negatively) for sites that manufacture them.
