I am seeking a senior-level Wix Technical SEO and Speed Optimization expert to rescue and rebuild the backend architecture of my e-commerce store. My site has experienced a significant indexing drop (from 5,000+ pages to under 400) due to heavy HTML code bloat (220kb+ document size), poor mobile performance, and broken internal routing.

- Implement dynamic Breadcrumb Navigation.

4. Hidden Code & Advanced Schema
- Restructure the H1–H3 HTML hierarchy in the backend code.

5. Risk Mitigation & Tracking
