Holographic

Holographic Lightweight SEO provides practical SEO controls for WordPress sites without front-end bloat, tracking scripts, unnecessary scripts or noisy dashboard nags.
It includes per-content SEO fields, XML sitemap support, schema, social metadata, breadcrumb output, SEO reports, conflict detection, metadata imports, redirects manager, 404 monitoring, CSV tools and lightweight admin screens.
