What is Total Blocking Time?
Total Blocking Time (TBT) is a measurement of how long a page loads. It measures how long a page’s block takes to load. When there is blocking, it takes longer for a visitor to have options on a website.
This is how TBT works
Total Blocking Time is part of Google Lighthouse; it is one of the Google Core Web Vitals. The loading time of a Web site is one of the most important components of a properly functioning site. The faster a page loads, the better. A slow website may cause visitors to leave your website and therefore not proceed to make a purchase.
Knowing about important things like Total Blocking Time will give you a better understanding of the current status of your website and how to change it. TBT measures what is going on on the website between the First Contentful Paint and the Time to Interactive, so to speak.

Total Blocking Time potentially impacts the SEO of a website or page, especially when you consider other important issues, such as Largest Contentful Paint and Cumulative Layout Shift. The latter two are important ranking factors for Google, so it is smart to include them in the SEO strategy.
Google Lighthouse’s key measurement tools offer great insight and opportunities for a website’s search engine optimization, as well as its usability.
