H&U Performance Nexus

The Ultimate Free Website Performance Audit Tool

Is your website losing traffic due to slow load times? The H&U Performance Nexus is an advanced, free SEO checker designed for developers, agencies, and business owners. Powered by the official Google Lighthouse API, it provides a comprehensive breakdown of your site's health, covering everything from Core Web Vitals to technical SEO errors.

Why Use Our Google PageSpeed Alternative?

While many tools give you a simple score, our auditor digs deeper. We provide a dual-layer analysis:
1. Field Data (CrUX): See exactly how real-world Chrome users experience your site (passing or failing).
2. Lab Data (Lighthouse): A simulated test to debug specific code issues like unminified CSS, large images, and slow server response times (TTFB).

Key Features of the H&U Nexus Tool

• Mobile & Desktop Analysis: Toggle between 4G mobile networks and Fiber desktop connections to ensure your site is responsive everywhere.
• Core Web Vitals Assessment: Instantly check if you pass Google's ranking signals: LCP (Loading), INP (Interactivity), and CLS (Visual Stability).
• Actionable Drill-Downs: Don't just see "Optimize Images." Click to expand and get the exact file URLs that are slowing you down.
• JavaScript & CSS Audit: Identify render-blocking resources and unused code that bloats your page size.

How to Improve Your Core Web Vitals

Improving your score requires a technical approach. Start by optimizing your Critical Rendering Path. Defer non-critical JavaScript, serve images in next-gen formats like WebP or AVIF, and implement aggressive caching policies. Use the diagnostics panel above to identify the "low hanging fruit" that will give you the biggest speed boost with the least effort.
