Why this matters for the Core Web Vitals, and where to start fixing it

The CMS decides your defaults: the theme's markup, the plugin economy, how images are sized, what loads in the head. Most sites never change those defaults, so the platform's choices become the platform's vitals.

No platform is doomed and none is safe. The spread inside a platform is bigger than the gap between platforms: a tuned site on a slow-median CMS beats a neglected site on a fast one. The platform pages rank them on real field data.

How does this affect the Core Web Vitals?

CMS correlates with the LCP. With Shopify, 96% of sites pass the LCP. With WordPress, 70% do. The causal link is weak: the choice mostly marks what kind of site made it.
