Total Blocking Time: how to improve

Total Blocking Time (TBT) is an important metric for measuring the performance of web pages. It refers to the amount of time that a page spends loading and executing scripts before it is fully rendered. A high TBT can result in a poor user experience, which can lead to increased bounce rates, lower conversion rates, and decreased engagement. In this article, we’ll explore some ways to improve TBT and create a better user experience for your website visitors.

Optimize Images to improve Total Blocking Time

Images are one of the most common causes of slow loading times on web pages. To reduce the amount of time it takes for your pages to load, you should optimize your images. This involves reducing their file size without sacrificing quality. You can use online tools like TinyPNG or Compressor.io to compress your images without losing quality.

Minimize CSS and JavaScript Files

CSS and JavaScript files can also slow down your page’s loading speed. To reduce TBT, you should minimize the number of CSS and JavaScript files that your page loads. You can do this by combining multiple files into one or by using a tool like webpack to bundle your files together.

Use a Content Delivery Network (CDN)

A Content Delivery Network (CDN) can help improve TBT by reducing the amount of time it takes for your content to reach users. CDNs work by storing copies of your content on servers located around the world. When a user requests your content, the CDN will deliver it from the server that is closest to them. This can help reduce latency and improve the overall speed of your website.

Reduce the Number of Third-Party Scripts

Third-party scripts can also have a significant impact on your page’s loading speed. These scripts include things like social media buttons, analytics tools, and advertising scripts. To reduce TBT, you should minimize the number of third-party scripts that your page loads. You can do this by removing unnecessary scripts or by using asynchronous loading techniques to delay the loading of non-critical scripts.

Optimize Server Response Time to improve Total Blocking Time

Server response time is the amount of time it takes for your server to respond to a user’s request. A slow server response time can significantly impact your TBT. To improve server response time, you can optimize your server’s configuration, reduce the size of your database queries, and use caching techniques to store frequently accessed data.

Use Lazy Loading to improve Total Blocking Time

Lazy loading is a technique that involves delaying the loading of certain page elements until they are needed. This can help improve TBT by reducing the amount of content that needs to be loaded at once. For example, you can use lazy loading to delay the loading of images that are below the fold or to delay the loading of scripts that are not critical to the initial rendering of the page.

Optimize Above-the-Fold Content

Above-the-fold content refers to the content that is visible on a user’s screen without scrolling. Optimizing above-the-fold content can help improve TBT by reducing the amount of time it takes for your page to become interactive. To optimize above-the-fold content, you should prioritize the loading of critical resources like CSS and JavaScript files, and reduce the size of your HTML, CSS, and JavaScript files.

Conclusion

In conclusion, Total Blocking Time is an important metric for measuring the performance of web pages. A high TBT can result in a poor user experience, which can lead to increased bounce rates, lower conversion rates, and decreased engagement. By optimizing images, minimizing CSS and JavaScript files, using a Content Delivery Network (CDN), reducing the number of third-party scripts, optimizing server response time, using lazy loading, and optimizing above-the-fold content, you can improve your website’s TBT and create a better user experience for your website visitors.
