How Website Speedy Helps with Total Blocking Time and First Input Delay

Among the most critical performance metrics are Total Blocking Time (TBT) and First Input Delay (FID). If your site suffers in these areas, users experience lag, frustration, and may bounce before they even see your content.

With Website Speedy, optimizations are implemented automatically to assist you in attaining improved speed and real-world performance.

What Are TBT and FID?
      1. JavaScript Optimization

Large or complex JavaScript can be a major cause of long TBT and FID. Website Speedy:

• Minifies and compresses JS files to reduce size.
• Defers non-critical scripts to load them only after the main content.
• Delays third-party scripts (like analytics and tracking tools) until after interaction.

Result: Reduced main thread blocking, which means that your site will be more responsive to user input.

        2.  Implement Lazy Loading

Website Speedy enables lazy loading effortlessly, ensuring that images and videos only load when the user scrolls down to them.

Result: Shorter load times, reduced TBT, and quicker FID response.

        3. Efficient Resource Loading

Website Speedy focuses on essential resources and employs the following:

• Preloading essential assets
• Async loading of fonts and non-essential styles
• Reducing render-blocking CSS/JS

Result: Faster rendering, reduced load on the main thread, and better interactivity scores

       4. Reducing Main-Thread Work

Generally long tasks contribute highly to TBT. Website Speedy identifies and optimizes them by:

• Breaking large scripts into smaller ones
• Minimizing third-party dependencies
• Reducing DOM size and complexity

Result: Smoother performance and quicker response to user interactions.

       5. Image and Asset Optimization

While images do not impact FID, large unoptimized assets can hinder the loading and execution of key scripts. Website Speedy:

• Converts images to next-gen formats (like WebP)
• Compresses assets without quality loss
• Uses adaptive image loading for mobile and desktop

Result: Lighter pages and less load on the browser thread.
