Serponado SEO Audit: What 8 Cluster Articles Reveal About Internal Links, Canonicals and Fragments

What this is about

Before we run the Serponado contest over the finish line, we ran a technical SEO check on the 8 cluster articles (4 DE, 4 EN): internal link status, canonicals, hreflang, fragment anchors. Short version below – full report as a download.

Results in detail

1. Frontmatter & canonicals

All 8 articles have slug, language, alternate_slug and modified: 2026-06-25 set. Canonicals rendered per-route via SEOHead (/blog/<slug> and /en/blog/<slug>). hreflang DE ↔ EN paired cleanly.

2. Internal linking

relatedPages on every article points to the three cluster siblings – DE to DE, EN to EN. No cross-locale leaks.

~11 internal links per article on average.

3. Fragment matches

4. Bugs fixed today

1. serponado-strategie.md – "Serponado Diary" anchor pointed to the Pillar instead of the Diary → fixed.
2. serponado-tagebuch-en.md – EN article linked Z.ai EN slug without /en/ prefix → fixed.

5. Open recommendations

• Add FAQPage JSON-LD on the Strategy page too
• Keep pushing backlink outreach (webinar with Felix Grote)
• Sitemap coverage of all 8 slugs verified via vite-plugin-sitemap (priority 0.8) ✅
• Image alt: all screenshots carry descriptive alt text ✅

Conclusion

Cluster is technically consistent and densely cross-linked. No broken links, no locale leaks, all canonicals self-referencing, all fragment anchors match. Ready for the final contest measurement.
