Large-Scale Next.js E-commerce SEO

My e-commerce platform serves more than 700,000 products from a MongoDB Atlas cluster through a Next .js 16 front-end, yet Google still indexes only a fraction of what we offer. I want to raise those rankings substantially and I’m ready to tackle every layer of organic SEO to do it—keyword optimisation, stronger on-page content, authoritative backlinks and, critically, deep technical fixes across the codebase.

Here is what I need from you:

• Technical overhaul in Next.js 16: generate clean, crawl-friendly URLs, automated title/meta tags, JSON-LD product schema and a scalable XML sitemap that updates as the catalogue grows.
• Performance tuning: pass Core Web Vitals for every page type; leverage server-side rendering and incremental static regeneration without overloading the database.
• Content & keyword strategy: map high-value keywords to category and product templates, then guide the content team on unique descriptions that avoid duplication at this scale.
• Backlink & authority plan: outline a realistic campaign to secure quality links that amplify trust signals for Google.
• Reporting & monitoring: set up Search Console, log-based crawling diagnostics and clear KPI dashboards so we can see ranking lifts over time.

Acceptance criteria
1. At least 90 % of product URLs discovered and indexed in Google within three months.
2. Core Web Vitals green across LCP, CLS and INP for homepage, category and product templates.
3. Documented workflow (repo commits or pull requests) showing how metadata, schema and sitemaps stay in sync with the MongoDB inventory.
4. Monthly report demonstrating ranking improvements for agreed target keyword clusters.

If you have proven experience scaling SEO on large Next.js or headless commerce builds, let’s talk about your roadmap and timeline for getting this done.
