SEO Governance Platform

TypeScript technical SEO governance portfolio project demonstrating metadata QA, canonical enforcement, structured data validation, redirect governance, and publishing-readiness workflows for enterprise websites.

Recruiter takeaway: "This person understands technical SEO as a platform governance problem, not just a content checklist."

Executive Summary

SEO Governance Platform models the kind of internal service enterprise web teams use to keep large sites compliant before new content, product pages, migrations, or redirects go live. Instead of treating SEO as a lightweight checklist, the project frames it as an operational control layer between marketing, content, web engineering, and platform governance.

The API validates metadata quality, canonical integrity, robots directives, structured data, redirect safety, and content depth, then translates those checks into a publishing-readiness score and clear operator actions. That makes the repo feel like a realistic internal platform capability rather than a toy SEO audit script.

Architecture

Content or URL change request
    |
    v
POST /api/validate/*
    |
    +--> Request validation
    +--> Governance rule checks
    +--> Metadata and content scoring
    +--> Schema or redirect safety review
    |
    v
Publishing readiness decision
    |
    +--> publish-ready
    +--> needs-review
    +--> blocked

Governance Workflow

1. Teams submit a page payload, schema payload, or redirect proposal.
2. The service validates request shape with Zod.
3. Governance logic checks metadata, canonicals, robots directives, heading depth, alt-text coverage, schema type allow-lists, and redirect safety.
4. The service returns a score, issues, passed checks, and recommended next action.
5. Operators use /api/dashboard/summary, /api/audits, /api/policies, and /api/redirects for visibility into governance posture.

Validation Model

Page Validation

Page scoring covers:

• title length and uniqueness
• meta description range
• canonical presence and self-reference
• robots directive validity
• heading depth
• image alt-text coverage
• allowed schema type
• thin-content and duplicate-risk indicators

Redirect Validation

Redirect review catches:

• source/target equality
• chain introduction
• loop behavior
• unsupported status code usage

Publishing Readiness

The publishing-check endpoint combines page and schema review into a single operational decision:

• publish-ready
• needs-review
• blocked
