Funnily enough the biggest offender of Cumulative Layout Shift (CLS) metric in my daily life is google search with its "people also search for" feature that causes me to constantly misclick. Lighthouse is great though :)

Curious how HN itself stands now.

It seems Accessibility measurement broke on web.dev/measure (the report mentions lighthouse 8.0.0):

Background and foreground colors have a sufficient contrast ratio - Error!

axe-core Error: Cannot read property 'filter' of undefined

This website had ~80 in accessibility before.

Edit: this issue was known before release: https://github.com/GoogleChrome/lighthouse/issues/11384

This is so exhausting, infuriating and perplexing. Just 1 week after managing to claw our LightHouse score up to 90 - its shot back down 72. The arbitrary nature of their weighting is just tiring - and its compounded by the fact that noone actually knows how much this actually impacts SEO.

Looks to me that you are not. using Lighthouse for the right reasons. Lighthouse isn't there to improve your SEO. It's just a set of heuristics that make you website performance - as perceived by end users - measurable, and thus improvable. They add a quantitative score on a very qualitative process. If you clawed your Lighthouse score to 90, you should have improved your end users experience, and that's what matters…

Google's Web Vitals page tracks things like Cumulative Layout Shift (CLS), First Contentful Paint (FCP), and Largest Contentful Paint (LCP). -- All of those metrics are visible in the Performance tab and are recorded by lighthouse.

From [1]: "The first reason is that cumulative layout shift will become a ranking factor in May 2021."

Well, clearly sites with no images or ads or javascript will score highly!

Why? HN is one of the most bare bones and barely usable sites.

ha, yes, absolutely. That shift of content is beyond frustrating.

Not sure if it's just me, but the Lighthouse CLI is so buggy that I've resorted to setting to up to run in a docker container so that it doesn't crash when trying to load certain sites/configurations. Hope that they work on improving stability at some point. That being said, kudos to the team on the release, I'm sure this is a challenging project to work on!

HN uses JS for the voting buttons.
