A batch of posts inserted straight into the database showed up correctly in every query, but the live homepage feed, category listing, and sidebar kept serving the version from before the insert.
Three different features on the same site broke the same way — content injected via innerHTML rendered fine structurally but came out completely unstyled — because of one Astro compile-time detail.
LCP, INP, and CLS each have a specific technical cause rooted in how a CMS renders pages — not vague 'optimization' advice. Here's what each metric actually measures, why CMS architecture determines your realistic ceiling on each, and what to check before choosing a platform.
WordPress, Webflow, Wix, and Squarespace all have independently published Core Web Vitals data worth comparing directly. EmDash doesn't have a third-party benchmark yet — here's the honest architectural comparison instead of a fabricated number.
Headless architecture doesn't make a site fast by branding alone — it removes specific bottlenecks: CDN-served pre-built pages instead of per-request server rendering, more crawl budget spent discovering pages instead of waiting on them, and metadata generated programmatically instead of set by hand.
Webflow sites average 2.3x faster LCP than WordPress, largely because they skip server-side rendering entirely. This guide compares which CMS platforms actually ship fast by default in 2026, and why architecture — not optimization effort — is the real deciding factor.
