Web vitals have very little impact on SEO though. Some of the top ranked sites have awful scores. Google has never said how much impact it has not I'd bet close to 5%.
We've actually seen web vital bugs tank our rankings pretty quickly. And fixing them resolved the ranking almost as fast.
I should specify that we are a timely news site, so there's some different mechanics at play. We mostly rank for content posted within the last 24-48 hours. Google has a slightly different set of rules for that kind of content vs marketing or evergreen.
Our biggest competitor fails in every Core Vital, and their page takes 13 seconds to load. Ours loads in under 2 seconds. They rank higher in every market. They run national ads and have tons of backlinks. Core Vitals aren't that important when compared to other things. If you're in a less marketable industry, your CLS being .01 better than your competitors isn't going to do anything. I can make my core vitals score absolutely perfect, but it could hurt user experience along the way. It's not a perfect metric by any means. Just something people bring up during sales pitches at this point.
