Dead links leak trust and crawl equity

Nothing says “abandoned site” like a resources page full of 404s. Broken outbound links frustrate readers; broken internal links strand crawlers. Catching them before a redesign or migration ships is cheaper than discovering them in Search Console months later.

Fah Swe Tools offers a Broken Link Checker that scans a public page with a capped, SSRF-safe crawl and timeouts — fair for shared hosting, not a replacement for enterprise crawlers on million-page sites.

What “limited crawl” means (and why that is good)

To protect your server and ours, the checker caps pages and link counts. That makes it ideal for:

For enormous sites, schedule a dedicated crawler — then use Fah Swe for quick verification of fixes.

How to run a broken link check online

1. Open Broken Link Checker. 2. Paste a public page URL. 3. Optionally raise max pages/links within safe caps. 4. Review OK vs broken statuses. 5. Fix URLs, add redirects, or remove dead references. 6. Re-run on the same page and a couple of children.

Localhost and private network targets are blocked.

FAQ

Will it find every broken link on a 50k-page site?

No — caps exist for fairness. Use it for focused audits.

Does it execute JavaScript SPAs deeply?

It follows HTML links within limits; heavy client-only routes may need extra coverage.

Is it free?

Yes on tools.fahswe.com.

Migration war rooms

During domain moves, run the checker on top templates: home, pricing, docs root, and top 10 blog posts. Fix high-traffic 404s first. Keep a spreadsheet of old→new mappings.

User-generated content

Forums and comment sections accumulate rot. Schedule quarterly sweeps on UGC-heavy templates or disable legacy outbound links.

Reporting

Export or copy broken results into tickets with owners. A scan without assignees changes nothing.

Editorial link policies

Prefer linking to pages you control for critical references. When citing external studies, archive important sources and monitor them quarterly with Broken Link Checker on cornerstone articles.

Design system pages

Component libraries and design docs accumulate outdated Figma and Notion links. Include them in monthly hygiene sweeps.

Post-migration acceptance

After cutover, check home, top landing pages, and the XML sitemap samples from XML Sitemap Generator. Fix loops with Redirect Checker. Broken-link QA belongs in the launch exit criteria, not “phase 2.”

Record before/after counts so leadership sees progress.

Deep dive: link hygiene as content debt management

Broken links are debt. Schedule monthly checks on money pages and quarterly checks on the long tail. Use Broken Link Checker for focused passes; escalate to full crawlers when the backlog grows.

Partner and affiliate URLs

Affiliate paths die when programs restructure. Monitor them separately because revenue depends on them.

Soft 404s

Some sites return 200 with “not found” bodies. Status-based checkers may miss those — spot-check suspicious “OK” rows manually.

Ownership

Assign each directory an editor. Unowned content rots fastest.

Field guide: triage severity for dead links

Severity 1: broken CTAs on pricing/signup. Severity 2: broken internal chapter navigation. Severity 3: broken outbound citations. Fix in that order. Track counts on a simple dashboard. Celebrate when Severity 1 stays at zero for a quarter. The Fah Swe Broken Link Checker is perfect for Severity 1 spot checks after each deploy — fast feedback without waiting for a full-site crawl to finish overnight.

Practical operating model for Broken Link Checker

Treat Broken Link Checker as a recurring habit, not a one-off novelty. Teams that win with Fah Swe Tools schedule light, frequent use: a pre-publish check, a weekly hygiene pass, or a release-train gate. The tool lives at /seo/broken-links and on https://tools.fahswe.com/seo/broken-links, which makes it easy to bookmark beside your CMS, IDE, or design suite.

Why Broken Link Checker belongs in your runbook

Scan a page (limited same-host crawl) for broken links — SSRF-safe with timeouts. That promise only compounds when someone owns the checklist item. Write the owner, the trigger (deploy, publish, incident, campaign), and the expected artifact (screenshot, CSV, ZIP, redacted log, framed PNG, or copied slug). Without an artifact, reviews become verbal and regressions return.

Collaboration patterns that scale

Pair specialists with generalists. A senior person demonstrates Broken Link Checker once on a real URL or file; juniors repeat on the next three. Capture the demo as a two-minute Loom or bullet list under your internal wiki. Link outward to related Fah Swe category hubs so people discover adjacent utilities instead of reinventing scripts.

Quality bar and anti-patterns

Anti-patterns include running Broken Link Checker only after customers complain, pasting production secrets into unrelated chats, or changing outputs without re-validating downstream pages. Prefer staging data when risk is high. Prefer smallest useful inputs when exploring. Prefer documenting the before/after so future audits take minutes instead of archaeology.

Thirty-day adoption plan

Week 1: add Broken Link Checker to the relevant checklist. Week 2: train the on-call or editorial pod. Week 3: measure a simple metric (checks run, KB saved, 404s closed, outlines shipped). Week 4: tune defaults and remove friction. By day 30 the tool should feel boring — which is exactly when it starts protecting quality.

Step reminders from the product page

1. Enter a public page URL.

2. Optionally raise max pages/links within safe caps.

3. Review OK vs broken statuses.

FAQ reminders worth repeating

Full site crawl? Capped for fairness (few pages / dozens of links). Use a dedicated crawler for huge sites.

Localhost? Blocked — private network addresses are not fetched.

When you are ready, open Broken Link Checker again on tools.fahswe.com and keep the loop tight: input, run, verify, ship.
