## 説明

WP Optimizer improves WordPress speed, Core Web Vitals, and technical SEO with a
modular toolkit.
 Enable only what you need: cache, minification, image optimization,
database cleanup, update controls, security hardening, and admin customization. 
All optimizations run on your server.

**WHY USING WP-Optimizer?**

 * **One plugin, full optimization workflow:** performance, maintenance, security,
   and admin cleanup from a single panel.
 * **Modular architecture:** enable only the modules you need to keep resource usage
   low.
 * **Built for real speed gains:** cache, minify, media optimization, cron tuning,
   and browser caching work together to reduce load time.
 * **Safer WordPress defaults:** security and update modules help reduce attack 
   surface and unwanted changes.
 * **Easier site management:** logs, diagnostics, mail logging, and dashboard widgets
   help you monitor and troubleshoot faster.
 * **Background processing:** long operations can run in background to avoid blocking
   admin work.
 * **Multisite support.**
 * **Privacy-friendly:** optimization runs on your server, with optional telemetry
   controls.
