Fix or remove broken external links

Maintaining the integrity of your outbound links is essential for a high-quality user experience and professional site reputation.

Code Example#

<!-- Regular auditing is required -->

    <!-- ✅ Good: Updated link to a live resource -->

    <!-- ❌ Bad: Linking to a known broken or archived resource without context -->

Why It Matters#

• User Experience: Prevents visitors from encountering frustrating "Page Not Found" errors when following your references.
• Site Quality: A high frequency of broken links suggests to search engines that the site is abandoned or not regularly audited.
• SEO Authority: Linking to high-quality, live resources is a positive signal; linking to dead ends is a negative one.
• Security: Expired domains you link to can be bought by malicious actors to serve malware or phishing content.

Exceptions#

• Staging, utility, login, account, or internal search pages may intentionally use different crawl or index signals if they are not meant to rank.
• Temporary migration states can produce noisy intermediate signals; flag the live production URL pattern, not one-off transition artifacts.
• When redirects, canonicals, robots directives, or indexability signals conflict, fix the strongest final signal first instead of reporting every downstream symptom as a separate blocker.

Standards#

• Use these references as the standard for the final search-facing HTML, metadata, and crawl behavior.
• Check the implementation against Google Search Central: Search Essentials before treating the rule as satisfied.
• Check the implementation against Google Search Central documentation before treating the rule as satisfied.

Verification#

Automated Checks#

• Inspect rendered HTML and HTTP headers to confirm the expected metadata or crawlability signal is present.
• Test the affected URL with Google Search Console or equivalent tooling where relevant.
• Re-crawl a representative page set after deployment.

Manual Checks#

• Confirm the change does not create conflicting canonical-url, robots, or structured-data signals.
