Implementing SEO Audit Findings
- Canonical, E-E-A-T, and Schema Fixes

Following an SEO audit of sighted.tkbase.co.jp (SEO Health Score: 68/100), we addressed Critical and High Priority issues. This article documents the improvements made.

Implementation Summary

Critical Fixes (Completed)
  • Canonical tag corrections
  • Privacy policy and terms of service metadata
High Priority (Completed)
  • Author byline and schema additions
  • DefinedTerm schema (glossary)
  • FAQ schema (/aeo page)

1. Canonical Tag Corrections

As flagged in the audit, the /privacy, /terms, /knowledge, /blog, and /glossary pages were all referencing the homepage (https://lp.sighted-aeo.com/) as their canonical URL. This has been corrected.

Changes Made
  • /privacy → canonical:https://lp.sighted-aeo.com/privacy
  • /terms → canonical:https://lp.sighted-aeo.com/terms
  • /knowledge → canonical:https://lp.sighted-aeo.com/knowledge
  • /blog → canonical:https://lp.sighted-aeo.com/blog
  • /glossary → canonical:https://lp.sighted-aeo.com/glossary

With each page now carrying a self-referencing canonical tag, search engines can correctly attribute ranking signals to individual pages.

2. Privacy Policy and Terms of Service Metadata

The /privacy and /terms pages were using the same title and description as the homepage. We added dedicated layout.tsx files for each page with unique metadata.

  • /privacy: Title: "Privacy Policy | Sighted", Description: "Sighted's privacy policy. How we handle personal information."
  • /terms: Title: "Terms of Service | Sighted", Description: "Sighted's terms of service. Conditions for using the service."

3. Author Byline and Article Schema

To strengthen E-E-A-T signals, we added author bylines (Shota Nagafuchi / CEO, Tech Knowledge Base) to blog articles and included the author property in Article schema markup.

Applied to:

  • Content-driven blog articles ([slug] pages)
  • Article JSON-LD with author Person schema

4. DefinedTerm Schema for the Glossary

Added DefinedTerm schema to all 16 glossary entries. Each term is linked via inDefinedTermSet to the "Sighted AEO Glossary" term set, making definitions more accessible to search engines and AI systems.

{
  "@type": "DefinedTerm",
  "name": "AEO",
  "description": "Short for Answer Engine Optimization...",
  "inDefinedTermSet": {
    "@type": "DefinedTermSet",
    "name": "Sighted AEO Glossary"
  }
}

5. FAQ Schema for the /aeo Page

The /aeo page contained FAQ-style content but lacked FAQPage schema markup. We added FAQPage schema covering key Q&As such as "What is AEO?", "How does AEO differ from SEO?", and "What are AEO measurement metrics?".

Future Actions (Medium Priority)

  • Expand glossary entries (target: 600+ words, up from 280)
  • Add social proof to the About page
  • Strengthen contextual linking within blog articles
  • Measure Core Web Vitals via PageSpeed Insights
