Surgical SEO. Zero Bloat. Born from the high-performance VonCMS ecosystem.

== Description ==

VonSEO isn't just another SEO plugin; it’s a **high-performance publishing engine**. Originally forged within the enterprise-grade **VonCMS** ecosystem, it has been meticulously adapted for WordPress publishers who refuse to compromise on speed, security, and database hygiene.

Stop turning your WordPress dashboard into a heavy SaaS marketing platform. It's time for **Performance-First SEO**.

### Why Choose VonSEO?

Most SEO plugins become increasingly heavy over time, trading performance for oversized dashboards, telemetry, and marketing layers. VonSEO rejects the bloat.

*   **Zero-Waste Architecture**: No custom database tables. We use native WordPress `post_meta` and `wp_options` for maximum speed and compatibility.
*   **Enterprise Heritage**: Built with the same performance DNA as VonCMS.
*   **Privacy as a Feature**: No tracking. No telemetry. No "phoning home." Your data stays on your server.
*   **No Paywalls**: What you see is what you get. No hidden “Pro” tabs or forced upgrades.

### The Professional Toolkit

A clean, focused editorial workflow designed for speed and usability.

*   **Instant Indexing (IndexNow)**: Instantly notify Bing and Yandex when content is updated.
*   **Surgical JSON-LD Schema**: Pure, optimized structured data (Article, FAQ, Video, Review, Breadcrumbs).
*   **SEO Table of Contents (TOC)**: Lightweight, anchor-based TOC with zero external dependencies.

#### 3. Safety & System Health
*   **System Health Monitor**: Real-time technical diagnostics for your PHP environment and permalinks.
