Improve TBT Performance on Blogger
Improve TBT Performance on Blogger
Total Blocking Time (TBT) is a critical performance metric that affects the responsiveness of your Blogger site.
Reducing TBT improves user experience by ensuring that your site responds quickly to user interactions.
Best strategies to optimize TBT
1. Optimize JavaScript
Minimize and defer JavaScript to reduce its impact on TBT.
2. Optimize CSS
Minify and inline critical CSS to reduce render-blocking.
3. Reduce Third-Party Scripts
Minimize or lazy load third-party scripts to improve performance.
4. Improve Rendering
Optimize images and use efficient fonts to enhance page load times.
5. Code Splitting
Split large JavaScript files into smaller chunks.
6. Use Browser Caching
Leverage browser caching to improve load times for repeat visits.
Monitor and Test
Regularly test your site using tools like Google PageSpeed Insights and Lighthouse to identify and address performance issues.

Speed up Loading Time For Blogger website's homepage
To speed up the loading time of a Blogger website's homepage, you can implement various optimization techniques.
Here’s a script that combines several best practices for improving page load performance.
You can insert this script into the `<head>` section of your Blogger template.
Optimizing Homepage Loading Speed
1. Minimize and Defer JavaScript:
- Combine and minify JavaScript files.
- Use `async` or `defer` attributes to load scripts asynchronously.
2. Optimize CSS:
- Minify CSS files.
- Inline critical CSS for faster rendering.
3. Use Efficient Image Handling:
- Implement lazy loading for images.
4. Improve Render-Blocking Resources:
- Inline critical CSS and defer non-essential CSS.

Script to Improve TBT Performance on Blogger
More Explanation:
- Critical CSS: Inline essential CSS in the `<head>` to speed up rendering.
This ensures that critical styles are applied immediately.
- **Fonts:** Use `media="print"` and `onload` attributes to load fonts asynchronously and avoid render-blocking.
- Deferred JavaScript:Load JavaScript files with the `defer` attribute to prevent blocking the rendering of the page.
- Lazy Loading: Implement lazy loading for images to defer loading until they are needed.
This script uses IntersectionObserver for modern browsers and provides a fallback for older ones.
Additional Tips:
- Combine and Minify Resources: Use tools like [Terser](https://terser.org/) for JavaScript and [CSSNano](https://cssnano.co/) for CSS to reduce file sizes.
- Use a Content Delivery Network (CDN): Serve your resources from a CDN to reduce latency.
- Optimize Images: Use modern image formats (e.g., WebP) and compress images to reduce their file sizes.
By following these practices, you can significantly improve the loading speed of your Blogger homepage, leading to a better user experience and potentially improved SEO.
