AI-Powered SEO Command Center
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.
The Challenge
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.
Our Solution
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.
Key Features Delivered
Two-Phase SSE AI Streaming Pipeline
Core phase streams meta titles, descriptions, and keywords, while extended phase generates JSON-LD structured data with credit reservation and 4 JSON extraction fallbacks.
100-Point Category Scoring Engine
Deterministic scoring algorithm evaluating content across 9 weighted categories (Basic, Content, Open Graph, Technical, Image, Robots, Social, Advanced) with actionable feedback.
Google OAuth 2.0 & Live GSC/GA4 Sync
Full Google OAuth integration for Search Console and GA4 with auto-token refresh on expiry, site property discovery, and secure token storage.
Composite 20+ Sub-Schema Data Model
Mongoose `SeoObject` schema housing Open Graph, Twitter Cards, JSON-LD, local SEO, video SEO, breadcrumbs, redirects, and verification tags.
Multi-Versioned REST API
Public V1/V2 endpoints with field-level merge resolution (item → collection → fallback priority) and programmatic XML/JSON sitemap generation.
Bulk Template & Quick-Fix Actions
Scalable optimization tools allowing content managers to apply bulk metadata templates and automated AI quick-fixes across 100+ pages simultaneously.
The Impact
The SEO Command Center consolidated auditing, metadata writing, AI streaming, and live Google search performance analytics into a single workspace.
- Accelerated SEO optimization cycles from hours to seconds via streaming AI metadata generation
- Eliminated context switching by merging on-page auditing, AI copywriting, and GSC/GA4 performance data
- Ensured analytics freshness through automated Google OAuth token lifecycle management
- Scaled page auditing to 100+ URLs via bulk template application and AI-driven quick fixes
