Core Web Vitals (CWV) Optimization Service

This service transforms routine website maintenance into a growth strategy, guaranteeing maximum user retention and compliance with Google’s critical performance standards.

Initial Audit & Deep Diagnostic

The first step in any optimization is establishing a clear baseline of performance.

• Performance Baseline Audit:
  • Initial measurement of LCP, FID, and CLS metrics using PageSpeed Insights and Lighthouse for all critical pages (Homepage, category, and product pages).
  • Analysis of Field Data (CrUX) from Google Search Console to pinpoint pages that fail to meet the "Good" threshold.
• Technical Diagnostic:
  • Review of Server Response Time (TTFB).
  • Resource structure analysis: identifying JavaScript Long Tasks and the total weight of CSS packages.
  • Review of image, font, and third-party embed implementation.

Monthly Optimization Plan (The CWV Strategy)

Maintenance focuses on specific monthly actions to consistently improve each metric.

LCP Focus (Loading)

• Critical Image Optimization: Conversion of key visuals (Hero, main banners) to next-gen formats (WebP or AVIF).
• Cache Management & CDN Tuning: Review and optimization of browser cache headers and fine-tuning of Content Delivery Network (CDN) settings.
• Resource Prioritization: Implementation or improvement of Critical CSS and the use of the <link rel="preload"> tag for important web fonts and essential resources.

FID Focus (Interactivity)

• Code Splitting: Identification and deferral of non-essential JavaScript needed for initial interaction.
• Long Task Reduction: Audit of third-party plugins and scripts that unnecessarily block the main thread.
• Execution Delay: Application of Lazy Loading techniques for all resources located below the fold.

CLS Focus (Visual Stability)

• Dimension Declaration: Ensuring that all images and media elements (videos, maps) have defined width and height attributes or use the CSS aspect-ratio property.
• Ad/Banner Management: Reserving fixed space for dynamic advertisements or pop-ups to prevent layout shifts.
• Font Control: Minimizing Layout Shift caused by the loading of external typography.

Transparency and client education are essential to showcase the value of this service.

• Monthly Performance Report: A clear report showing the previous month's CWV metrics and progress toward the "Good" threshold.
  • Includes screenshots of the PageSpeed Insights dashboard.
• Quarterly Strategy Meeting: Presentation of performance trends and recommendation for additional investments (e.g., upgrading PHP version, migrating to faster server infrastructure) based on hard data.
