AI-Powered SEO Command Center is a full-stack SaaS platform featuring a two-phase Server-Sent Events (SSE) AI streaming pipeline, a 100-point deterministic SEO scoring engine, Google OAuth 2.0 lifecycle management for GSC and GA4, and multi-versioned public REST APIs.
Built under NDA — client data and source code remain confidential, so details are intentionally limited.
Content teams and SEO professionals lacked a unified platform to audit site health, manage on-page SEO at scale, and generate metadata with AI — while maintaining real-time sync with Google Search Console and Google Analytics 4. Existing solutions were either too generic or required manual workflows across disconnected tools. The challenge was building a single platform to crawl and score 100+ page factors, stream AI-generated SEO optimizations in real time, and connect directly to Google's APIs.
We architected a full-stack SEO Command Center using Next.js 15 (App Router, Zustand, React Query, Recharts) and NestJS (21+ REST endpoints, Mongoose ODM). It includes a two-phase SSE streaming pipeline for AI metadata generation with 4 fallback JSON parsers, a 100-point 9-category client scoring algorithm, Google OAuth 2.0 with auto-token refresh, and a composite MongoDB store with 20+ sub-schemas.
Engineered from scratch with clean code, scalable architecture, and strict attention to performance.
Core phase streams meta titles, descriptions, and keywords, while extended phase generates JSON-LD structured data with credit reservation and 4 JSON extraction fallbacks.
Deterministic scoring algorithm evaluating content across 9 weighted categories (Basic, Content, Open Graph, Technical, Image, Robots, Social, Advanced) with actionable feedback.
Full Google OAuth integration for Search Console and GA4 with auto-token refresh on expiry, site property discovery, and secure token storage.
Mongoose `SeoObject` schema housing Open Graph, Twitter Cards, JSON-LD, local SEO, video SEO, breadcrumbs, redirects, and verification tags.
Public V1/V2 endpoints with field-level merge resolution (item → collection → fallback priority) and programmatic XML/JSON sitemap generation.
Scalable optimization tools allowing content managers to apply bulk metadata templates and automated AI quick-fixes across 100+ pages simultaneously.
The SEO Command Center consolidated auditing, metadata writing, AI streaming, and live Google search performance analytics into a single workspace.
