What else to know about these numbers? The Total Blocking Time (TBT) from Lighthouse v8 is the time between First Contentful Paint and Time to Interactive (TTI) during which the main thread was blocked large enough to prevent response.

Remember that in the analysis of laboratory data you can filter the results by clicking on the items that show controls related to FCP, TBT, LCP and CLS. You can also analyze in depth everything you can do to obtain interesting results in terms of performance. A concrete example?
Remove view-blocking resources
The concept is simple: the browser must load the web page but Javascript and CSS can prevent this work because they pretend to load before showing the rest of the resource.
This even when they are useless. This is why it is important to define each step. For an initial optimization you can use different WordPress plugins that serve precisely this purpose. I point out two:
AsyncJavaScript
Hummingbird

How to track data on WordPress?
You don’t want to analyze every single page, it seems clear to me. That’s why there are some solutions to aggregate data. For example, Google Analytics suggests a report of the slowest pages and the Search Console does the same . But one of the most interesting solutions is the Site Kit plugin for WordPress .
Site Kit for WordPress - Google plugin
This tool combines the parameters of the tools to monitor the health of the website . And among the different tools you have Pagespeed Insights by Google. Want to take a look? Here is the page: sitekit.withgoogle.com . Download and install the plugin, log in with the services and enjoy the data in the WordPress dashboard.
Is Pagespeed data accurate?
Google's Pagespeed checks are performed through the Lighthouse diagnostic tool , a suite from Mountain View that analyzes accessibility, SEO elements and UX . And it is Google itself that specifies the possibilities of this suite. Even its tools have concrete limits:
PSI provides both lab and field data about a page. Lab data is useful for debugging performance issues, as it is collected in a controlled environment. However, it may not capture real-world bottlenecks. Field data is useful for capturing true, real-world user experience – but has a more limited set of metrics.

As mentioned, Pagespeed suggests both lab and field-recorded data. The lab data is useful for troubleshooting performance issues but may miss bottlenecks that are holding up the loading of a resource. At the same time, field-recorded data has a limited set of metrics.
For this reason, as is especially the case with the version released on November 15, 2021 , importance is placed on the synergy between field data that keep track of the situation and laboratory data.

Not to mention the possibility of getting different results. John Mueller suggests that the output can change without having made any changes. For this reason, it is useful to compare the data from Google Pagespeed Insights with other tools (such as Gtmetrix , Pingdom or Speed ) to get more information.
Want to reach 100/100 on PSI?
This is one of the points of maximum ambition: to touch 100/100 on Google Page Speed Insights. Therefore optimizing the advice suggested by Mountain View through this tool. But is it possible? And is it useful?
I echo John Mueller: we use this tool not to hit 100 out of 100 but to improve the user experience. Often we work only to satisfy the metric while ignoring what we offer.
This score is often obtained on half-empty pages : if this is your goal, it's fine, but can you remove what characterizes you to reach this point? Never think only in terms of metrics.

What is Pagespeed Really Good For?
Can we perhaps say that PSI data is wrong or superfluous? No, we must read the data for what it is: useful information in the hands of an expert who has the task of reading and interpreting it. To then carry out the necessary activities to obtain the best possible result for the user (and not to please Goo
