If you’ve ever launched a marketing page, published documentation, or maintained a growing blog, you’ve probably felt this pain: everything looks great-until months later, users start landing on broken links, outdated resources, or pages missing essential SEO metadata.
At Bix Tech, we run into this in real life with product teams, marketing teams, and engineering teams that ship fast. So we built something simple and practical-and then we made it public.
We created an open-source GitHub project that checks dead links and SEO tags:

This post explains what the tool does, why it’s important, and how teams can use it to protect user experience and improve search visibility-especially as sites scale.
About Bix Tech (Quick Intro)
Bix Tech is a software and AI agency that provides nearshore talent to US companies. We’ve been building and scaling digital products since 2014, and we operate with two branches in the US and Brazil.
Open-source tools like this reflect how we work: practical engineering, focused on quality, and built to integrate smoothly into real delivery pipelines.
Why Dead Links and Missing SEO Tags Are Bigger Problems Than They Look
Broken links and incomplete metadata aren’t just “small website issues.” They compound over time and quietly hurt performance across multiple dimensions.
Dead links impact:
- User experience: Visitors hit a dead end and lose trust quickly.
- Conversions: Broken links in CTAs, pricing pages, or lead forms can directly reduce revenue.
- Maintenance overhead: Teams end up firefighting issues that could be caught automatically.
Missing or inconsistent SEO tags impact:
- Search visibility: Pages without proper metadata are harder for search engines to understand and rank well.
- Link previews: Social sharing previews can look incomplete or unprofessional.
- Content consistency: Large websites drift over time-especially when multiple authors or squads publish.
In other words: dead links and SEO tag gaps are quality issues that show up as marketing issues and revenue issues later.
Introducing the Dead Link & SEO Checker (Open Source)
We built the Dead Link SEO Checker to automate two recurring checks:
- Dead link validation: identify links that return errors or fail to resolve.
- SEO tag verification: detect missing or incomplete tags that commonly matter for SEO and shareability.
This is especially useful for:
- Marketing websites with lots of landing pages
- Documentation sites that frequently change URLs
- SaaS apps with public knowledge bases
- Content-heavy blogs with years of posts

What the Tool Checks (Conceptually)
Even if your team already runs tests, link and metadata validation often slips through because it’s “not product logic.” This tool focuses on website hygiene.
1) Dead link detection
Typical checks include identifying URLs that:
- Return 4xx errors (like 404 Not Found)
- Return 5xx errors (server-side failures)
- Time out or fail to resolve consistently
This matters because a link can be “valid” when published-but become dead when:
- A partner site reorganizes content
- A blog post is moved without a redirect
- Docs versioning changes old URLs
- A CMS migration breaks slug patterns
2) SEO tag checks
Teams often forget metadata when shipping quickly or templating pages. Commonly validated elements include:
- Page titles and meta descriptions
- Canonical tags (when relevant)
- Indexing directives (noindex/nofollow where applicable)
- Social preview tags (depending on your standard)
The big win here is consistency. It’s not just about having tags-it’s about having them reliably across templates and content types.
Where This Fits in a Modern Workflow (CI/CD-Friendly)
One of the most practical uses of a dead link and SEO tag checker is running it continuously-not “once before launch.”
Recommended places to run it:
- Pull requests: catch broken links before merging content or UI changes
- Nightly builds: detect external link rot over time
- Pre-release checks: validate your public-facing pages before shipping
Typical scenarios we see:
- A marketing team updates navigation links → one route changes → 20 pages now point to a 404
- Documentation reorganized for a new version → old pages still referenced internally
- A “small” landing page added quickly → missing meta description → weak SERP snippet
Automated checks make these issues visible early, when fixes are cheap.
Practical Tips: How to Reduce Broken Links and SEO Gaps (Beyond the Tool)
A checker is powerful-but pairing it with good habits makes it even more effective.
1) Use redirects strategically
When URLs change, add 301 redirects whenever possible. It preserves SEO equity and prevents user frustration.
2) Standardize SEO metadata by template
If you use a CMS, Next.js, or another framework, ensure every page type has defaults for:
- title
- meta description
- canonical (if needed)
- social preview image/title/description
3) Treat external links as “dependencies”
External links will break eventually. Consider:
- linking to stable sources (official docs over random blog posts)
- periodically validating outbound links (great use case for scheduled runs)
4) Track results and fix patterns
If you repeatedly see the same kind of missing tag, that’s a system issue-not a one-off mistake. Fix the template or publishing workflow.
Who This Open-Source Project Is For
This project is ideal if you’re:
- a developer maintaining a public site and want an automated dead link checker
- a marketing team working with engineering and needing SEO hygiene guardrails
- a product team shipping fast and wanting quick, repeatable quality checks
- a CTO or tech lead trying to prevent “website drift” as content scales
It’s also a great fit for distributed teams-which is exactly where nearshore collaboration shines: marketing and engineering can move quickly without sacrificing fundamentals.
Why We Open-Sourced It
We open-sourced this tool because it solves a real, recurring pain-and we know other teams face the same thing.
At Bix Tech, we help US companies scale delivery with nearshore engineers in Brazil while keeping product quality high. Tools like this reflect our mindset:
- build practical automation
- reduce manual QA
- improve reliability and SEO readiness
- keep teams shipping confidently
