Broken link building has been around long enough that most SEOs have tried it at least once, usually with mixed results. The tactic itself is sound: find dead links pointing to 404 pages, create or repurpose content that fills the gap, then pitch the linking site with a replacement. Clean logic. But the execution is where most campaigns fall apart, and I’ve watched a lot of agencies abandon it prematurely because their outreach sequences were weak or their prospecting was too narrow.

After auditing hundreds of link profiles and running broken link campaigns across sectors from legal tech to D2C e-commerce, the pattern is consistent. Agencies that treat this as a volume game get poor acceptance rates. Agencies that layer it into a broader link acquisition mix, with proper anchor strategy and velocity control, see compounding returns over time.

This post is aimed at practitioners who are already running link building at scale. We’ll cover the full strategic picture: how to prospect efficiently, how to craft outreach that gets replies, how broken link fits alongside editorial link acquisition, niche edits and digital PR, and how to report on it in a way that actually means something to clients. There’s no padding here. If you want the fundamentals of what a backlink is, this isn’t the piece for you.

Why Broken Link Building Still Earns Its Place in 2025

The Supply Side Has Changed

Web content decays faster than it used to. Sites migrate platforms, rebrand, sunset product lines, and let domains lapse. That creates a constant supply of dead outbound links sitting on otherwise healthy pages. Ahrefs data consistently shows that a significant proportion of pages with external links contain at least one broken outbound URL, and in older, content-heavy niches like finance, health and B2B SaaS, the rate is higher.

The quality of available opportunities has also shifted. Five years ago, broken link prospecting often surfaced low-authority resource pages that weren’t worth the effort. Now, with better filtering in Ahrefs and SEMrush, you can isolate referring pages with genuine DR, organic traffic, and topical alignment. The noise is easier to remove. That changes the ROI calculation meaningfully.

It Earns Editorial-Grade Links Without the Price Tag

One thing I’d push back on is the idea that broken link placements are somehow lower quality than traditional editorial links. If the replacement content is genuinely useful and the host page is editorially maintained, the link signal is functionally the same. The difference is that you initiated the relationship rather than waiting for a journalist to find you. For agencies managing SEO campaigns with limited digital PR budgets, that distinction matters a great deal.

The Strategy Breakdown

Prospecting at Scale Without Burning Quality

The most efficient prospecting workflow I’ve used combines Ahrefs’ broken backlinks report with Content Explorer to identify high-traffic pages in the target niche that contain dead outbound links. Filter by DR 40 and above, exclude forums, wikis and social aggregators, and prioritise pages with organic traffic above 500 monthly sessions. That last filter is one a lot of teams skip. A page with DR 60 but zero organic traffic isn’t delivering referral value or passing much crawl equity in practice.

Export your list, then run it through a deduplicated domain filter before you do anything else. You don’t want three team members pitching the same domain in the same week. BuzzStream and Pitchbox both handle this deduplication well at the campaign level, though Pitchbox’s prospecting automation is stronger if you’re running multiple concurrent campaigns.

For very specific niches, I’d also recommend pulling the Wayback Machine API to check what the dead URL used to host. This tells you exactly what content angle to use in your outreach, and it’s the kind of personalisation that moves acceptance rates from 4% to 12% in my experience.

Anchor Text Strategy Across a Mixed Link Profile

This is where a lot of agencies make errors that take months to surface. Broken link placements often allow some degree of anchor influence, because you’re suggesting replacement content and the webmaster may follow your lead on how they link to it. That’s both an opportunity and a risk.

The standard rule still applies: keep exact-match commercial anchors to a small minority of your total profile. For most client profiles we manage, we’re targeting somewhere between 5% and 15% exact match, with the rest distributed across branded, partial match, naked URLs and topical generics. Where broken link placements give us flexibility, we use partial match and topical anchors deliberately. They read naturally, they align with the surrounding content, and they don’t concentrate risk.

Run your anchor distribution through Majestic’s anchor text report alongside Ahrefs every quarter. The two tools surface data slightly differently, and cross-referencing catches anomalies that either alone might miss.

Link Velocity and Pacing Campaigns Sensibly

Link velocity matters, and it’s consistently underweighted in agency planning. A client with a DR 22 domain acquiring 40 new referring domains in a single month will flag patterns that careful, steady growth avoids entirely. We pace new link acquisition relative to the existing profile size and the natural growth rate for the sector.

For a mid-market B2B SaaS client we worked with last year, we brought domain rating from 24 to 41 over six months by combining broken link outreach with digital PR and selective niche edits. The monthly referring domain growth averaged between 8 and 14 new domains. Nothing dramatic. The gains were sticky because the velocity looked organic and the content supporting the links was legitimately useful.

Toxic Link Removal as a Precondition

Before any broken link campaign goes live, the existing profile needs a clean audit. I won’t build on a compromised foundation. Use Ahrefs or SEMrush to pull the full backlink profile, segment by spam score, and cross-reference with Google Search Console’s manual actions panel. Disavow anything that’s clearly manipulative: footer links from unrelated PBNs, comment spam, bulk directory submissions with no topical fit.

This step is particularly important for clients who’ve inherited profiles from previous agencies. I’ve seen sites where 30% of referring domains were effectively dead weight or actively harmful. Clearing that before building is not optional if you want clean attribution data and sustainable results.

Advanced Tactics Most Agencies Overlook

Combining Broken Link with Niche Edits for Faster Wins

Broken link building has a natural delay built in: you find the opportunity, create or locate the content, pitch, wait for a response, and chase. That cycle can run three to six weeks per placement. For clients who need quicker referring domain growth, pairing broken link outreach with niche edit campaigns running in parallel gives you a dual velocity. The niche edits deliver faster, the broken link placements tend to be slightly higher quality and more defensible long-term.

The two tactics also share prospecting infrastructure. If a site doesn’t have a relevant broken link but does have a strong existing page where a natural link to your client would fit, pivot to a niche edit pitch in the same outreach sequence. BuzzStream lets you tag prospects and switch them between campaign sequences without losing the contact history.

HARO Alternatives and Digital PR Integration

HARO’s decline as a reliable source pipeline has pushed a lot of agencies toward alternatives: Qwoted, ResponseSource, Featured, and Connectively are all viable depending on the client’s sector and the journalist demographics you’re targeting. ResponseSource tends to perform better for UK media, which matters if your client base is predominantly domestic.

Where broken link building and digital PR intersect is in content creation. Assets built for broken link replacement, original data, updated guides, refreshed statistics pages, are often strong enough to fuel a simultaneous PR push. A piece of original research that replaces a dead resource page on one site might also earn coverage from three journalists. You’re building once and distributing across channels. That’s efficient use of content budget, and clients appreciate seeing the overlap clearly explained in reporting.

Editorial Links Through Relationship Sequencing

The best broken link campaigns I’ve run haven’t ended with a single placement. They’ve opened a relationship with a site editor that leads to editorial inclusions in future content. When your outreach is genuinely helpful, when you’re not asking for anything they wouldn’t want to give, webmasters remember. Following up with relevant resources or data three months later converts at a higher rate than cold outreach to a new contact.

Track these relationships in your CRM. Pitchbox does this reasonably well with its relationship tagging. BuzzStream is arguably better for long-term relationship management across a large contact list. Either way, the warm pipeline you build through broken link work feeds your editorial link acquisition over time.

Measuring and Reporting Performance

Metrics That Actually Reflect Campaign Health

Client reporting on link building is an area where I see a lot of agencies over-relying on DR movement as the primary KPI. DR is a lagging indicator and it’s influenced by factors outside your control. More useful signals include: referring domain growth rate month on month, the organic traffic profile of pages linking to the client, anchor diversity trends, and whether target keyword positions are moving in correlation with the link acquisition timeline.

Google Search Console is underused here. Tracking impressions and click data for target pages alongside the link building activity gives you a more honest picture of whether the links are driving crawl and index behaviour. If a cluster of new referring domains coincides with a measurable uptick in impressions for those pages, you’ve got a correlation worth reporting.

Attribution and Setting Realistic Expectations

Links are one factor among many. I’m direct with clients about that. If the on-page optimisation is poor or the site has technical issues that limit crawlability, link acquisition won’t compensate. Attribution in SEO is inherently imprecise, and any agency claiming otherwise is overselling.

What you can do is build a clear before-and-after picture: baseline metrics at campaign start, a documented link acquisition log with placement dates and page-level DR, and a rolling keyword position tracker for target terms. That gives you a credible narrative even when the causality isn’t perfectly clean.

Real-World Application

We ran a broken link campaign for a UK-based legal technology platform entering a competitive SaaS space. Starting DR was 19, with a thin referring domain profile of around 35 domains, most of them low-authority directories from an earlier SEO engagement.

After the initial toxic link audit and disavow pass, we began prospecting using Ahrefs’ broken backlinks report filtered to legal tech, RegTech, and compliance content. We identified 340 viable prospects over eight weeks. Outreach went out through Pitchbox with a three-step sequence: initial pitch, value-add follow-up linking to a relevant secondary resource, and a final courtesy close.

Acceptance rate across the campaign was 9.4%. Over six months, the client gained 47 new referring domains from the broken link work, with an average referring page DR of 44. Niche edits running in parallel added a further 22 domains. Combined with two digital PR placements that landed on UK tech media sites, the domain rating moved from 19 to 38 by month seven. Target keywords in the compliance software cluster moved from outside the top 50 to consistent top 10 positions for three primary terms. No dramatic spikes. Steady, defensible progress.
