Project details
Is your website losing traffic, ranking poorly, or driving away mobile users? Most performance issues stem from hidden code errors and slow loading times.
As a Senior Frontend Developer, I will conduct a comprehensive technical audit of your website using Google Lighthouse and the W3C Validator to translate raw data into a clear, business-driven optimization roadmap.
What this audit covers:
• Performance & Core Web Vitals (LCP, INP, CLS) for Mobile and Desktop.
• W3C Code Validation to catch structural HTML/CSS syntax errors.
• A prioritized, step-by-step Implementation Roadmap (Action Checklist).
• Competitor benchmark analysis to see why rivals rank higher (Advanced tier).
No technical jargon. You will get a clear, easy-to-read PDF report showcasing exactly what is slowing down your site and a precise blueprint for your developer to fix it.
Note: This project catalog focuses on website performance auditing. No direct file modifications or live code optimizations are included in this service.
