I wrote about the Backlinko results in November 2019 on LinkedIn, tagging Brian as well. But it looks like Brian already put some effort into the pagespeed of his website. As a result, he is now passing Core Web Vitals.
Mid november, Google announced when and how Core Web Vitals will be part of organic ranking. In May, where pages will have a visual indicator of meeting Core Web Vitals. The first tests of Google were already seen.
As of April 6, 2020, data-vocabulary.org markup will no longer be eligible for Google rich result features. Nothing new here for webdevelopers and SEO specialist out there. However..
If you are a professional Web Performance Optimizer (WPO), or if you are simply someone who cares about online performance and pagespeed, chances are that you are doing these performance optimisations wrong.
