Broken link building is one of the few link acquisition strategies that offers three parties a genuine win simultaneously: the website owner gets a broken link fixed, their visitors get a working resource, and you earn a backlink. No cold pitch pretending to be a compliment. No “I noticed you write about X” opener that fools nobody. Just a straightforward value exchange — you found a problem on their site, you have a solution, and you are offering it. The reason most UK SEO teams either ignore broken link building or run it at a frustratingly small scale is not that the strategy does not work. It is that the manual version — crawling individual competitor pages by hand, checking each link one at a time, logging prospects in a spreadsheet, writing individual outreach emails — is genuinely tedious at low volume and completely unmanageable at high volume. The tool version, combining Screaming Frog’s crawling capabilities with Ahrefs’ link intelligence, changes this equation entirely. What takes a researcher days of manual work can be executed in hours. What produces ten outreach prospects from a morning’s work can produce three hundred. And because the targeting logic is precise — you are reaching out to site owners with a specific, verified problem and a specific, verified solution — conversion rates on broken link outreach consistently outperform generic guest post pitches by a significant margin. This is the complete methodology: how to find broken link opportunities at scale, how to prioritise them intelligently, how to create or repurpose the replacement content, and how to execute outreach that generates genuine, authoritative backlinks for UK businesses. Why Broken Link Building Still Works – and Why Most UK Competitors Are Not Doing It Before the methodology, the strategic case. Link acquisition strategies go through cycles of adoption, saturation, and decline. Guest posting, once a high-signal tactic, became so widely abused that Google’s guidance explicitly discounts guest post links acquired for SEO purposes. Skyscraper campaigns became saturated as every agency adopted the same “I noticed your page links to X, I wrote something better” template. Resource page link building remains viable but is increasingly competitive. Broken link building occupies a different position in this landscape. It is labour-intensive at the research stage — which is precisely why most teams avoid it — but that labour intensity is the moat. The strategy cannot be fully commoditised because the broken link discovery and prospect qualification steps require either genuine tool expertise or substantial manual effort. The agencies and in-house teams that invest in building the tooled workflow described in this guide inherit a competitive advantage that their less-resourced competitors cannot easily replicate. The conversion logic is also structurally different from other outreach strategies. When you email a site owner about a broken link, you are not asking them to do you a favour. You are telling them their site has a problem — a dead link that damages their user experience and wastes their crawl budget — and offering to help fix it. The psychological dynamic is fundamentally different from a cold link request, and it shows in response rates. Well-executed broken link outreach in the UK market consistently achieves response rates of 15 to 25%, compared to 3 to 8% for typical guest post cold pitches. The Two-Track Approach: Competitor Analysis and Niche Crawling Broken link building at scale operates on two parallel tracks, each suited to different research contexts and producing different types of opportunities. Track 1: Competitor backlink analysis via Ahrefs — Identifying broken pages on sites that already link to your competitors, then pitching your content as the replacement. This track targets the highest-authority link opportunities because the donor sites have already demonstrated a willingness to link to content in your niche. Track 2: Niche site crawling via Screaming Frog — Crawling a curated list of authority sites in your target niche to find broken outbound links, then creating or repurposing content that matches the dead resource. This track generates a higher volume of prospects and surfaces opportunities that competitor analysis misses because the linking sites may not be pointing at any of your known competitors. The most effective UK broken link building programmes run both tracks simultaneously and manage the resulting prospect pipeline through a unified qualification and outreach workflow. Let us walk through each track in detail. Track 1: Competitor Broken Backlink Analysis with Ahrefs Step 1: Build your competitor list Begin with three to five direct competitors whose backlink profiles represent the type of links you want to earn. For a UK digital marketing agency, this means agencies of comparable size and service offering ranking for the same commercial keywords — not the large platforms (Moz, Search Engine Land, HubSpot) whose link profiles are too broad to generate actionable niche opportunities. In Ahrefs Site Explorer, enter the first competitor’s domain and navigate to the “Best by Links” report under “Pages.” Sort by “Referring Domains” descending. You are looking at the pages on this competitor’s site that have attracted the most linking root domains — but crucially, you want to filter this list for pages that no longer exist. Step 2: Filter for broken pages with inbound links Still in Site Explorer, navigate to “Best by Links” and apply the HTTP code filter: select “404 not found.” This surfaces pages on your competitor’s domain that are returning 404 errors — dead pages — but that still have external sites linking to them. The referring domains are linking to a broken resource. They are, by definition, open to hearing about a replacement. Export this list. For each broken URL, Ahrefs shows the number of referring domains pointing to it. Sort descending by referring domains and work from the top. A broken page with 15 referring domains pointing to it represents 15 potential outreach prospects from a single dead URL — that is the efficiency multiple that makes this approach viable at scale. Step 3: Evaluate the dead content For each broken URL with
