Broken Link Building in 2025: Turn Dead Links into SEO Gold (Free Tools + Scripts)

Hey, SEO sleuths! 🔍 Welcome back to Backlink Haven. Over the past 9 days, we’ve covered guest posting, toxic links, and *link-worthy content*. Today, we’re unlocking a sneaky 2025 hack: broken link building—where you turn other people’s mistakes into your SEO wins.
Imagine this: A blogger links to a dead page about “AI SEO tools.” You swoop in, offer your updated AI tools guide, and BAM—free backlink. 🚀 Let’s learn how to do this without sounding like a vulture.
Why Broken Link Building Still Works in 2025
Broken links are everywhere (and Google hates them)
- 42% of blogs have at least 5 broken links (2025 HubSpot data).
- Fixing them helps your site AND the site owner—it’s a win-win.
2025 twists you need to know
- AI-powered audits: Sites like WordPress now auto-flag broken links… but most webmasters ignore them.
- E-E-A-T boost: Google rewards links from “helpful” content (like yours replacing a dead resource).
Step 1: Find Broken Links (5 Minutes)
Tools to automate the hunt
- Ahrefs 2025: Enter a competitor’s URL → “Backlinks” → Filter by “Broken.”
- Checkbot (Chrome Extension): Crawls sites for broken links while you browse.
- DeadLinkSEO.com: Free broken link checker updated for 2025.
Target sites with
- High DA (40+).
- Resource pages or “best tools” lists (prone to outdated links).
👉 Example: Find a 2023 “Top AI SEO Tools” post with dead links. Your 2025 guide is the perfect fix!

“What If They Ask for Money?”
2025’s unspoken rule
