There seems to be a misconception that the Lighthouse score is linked to the page experience search rank update. Higher Lighthouse scores won't give you better SEO. Only better results from field data (albeit only Chrome field data) will impact your search results [1]. Lighthouse is only intended to be a guide (name checks out) for developers to identify potential opportunities to improve real-user performance. Core Web Vitals is how Google has decided to align lab and field data in a more unified way. Historically, this has been pretty difficult, particularly with interactivity measurements. For example, Total Blocking Time (TBT) is a lab proxy metric for First Input Delay (FID) — they don't measure the same thing. The team at Google has frequently communicated that the only true way to know is from measuring on real users [2]. While the metrics aren't perfect, they are taking in feedback to adjust how metrics are measured and weighted, such as with the windowed CLS update [3]. I for one have found the tools and browser support for measuring performance to have improved significantly, even in the last few years. Kudos to the Web Perf community, who I'm sure would appreciate any feedback.
