In a manner of speaking

Moi: What percentage of websites get perfect scores of 100 in all Lighthouse categories?
Grok: Achieving a perfect score of 100 in all Google Lighthouse categories (Performance, Accessibility, Best Practices, SEO, and Progressive Web App) is extremely rare. According to data from the HTTP Archive, as cited in a 2020 analysis, only about 1% of websites score 99 or higher in the Performance category alone, with even fewer achieving perfect scores across all categories due to the stringent requirements and variability in testing conditions. The complexity of modern websites, including factors like third-party scripts, dynamic content, and accessibility nuances, makes a perfect score in all categories highly challenging. Specific data on the exact percentage of websites achieving a perfect 100 across all categories is not explicitly documented in available sources, but it is likely well below 1% based on the performance metric trends. https://www.tunetheweb.com/blog/what-do-lighthouse-scores-look-like-across-the-web/
Moi: Almost every page on our website, woodcentral.com, is now getting perfect Lighthouse scores and passing the Nu Html Checker with no errors or warnings. The only exceptions are Open Source packages we have integrated into it where we do not have adequate control of the HTML and CSS.
Grok: That's impressive! Achieving perfect Lighthouse scores and passing the Nu Html Checker with no errors or warnings across most pages on woodcentral.com is a significant accomplishment, especially given how rare it is for websites to hit that mark in all categories (Performance, Accessibility, Best Practices, SEO, and PWA). The fact that only your integrated open-source packages are preventing a clean sweep speaks to the strength of your site's optimization.
WoodCentral is now the PERFECT website!
