Core Web Vitals for Marketing Teams

Marketing teams feel performance as bounce rate and conversion. Engineers feel it as LCP, INP, and CLS. The bridge is a short list of high-leverage fixes that protect brand design while making pages feel instant.

Fix LCP first

Hero images are the usual LCP culprit. Serve modern formats (WebP/AVIF), size correctly, and avoid `unoptimized` unless you have a documented reason. Priority-load only the true LCP candidate.

• Compress marketing heroes to roughly 200–400KB where possible
• Use next/image with accurate sizes attributes
• Keep above-the-fold CSS lean — avoid shipping entire feature CSS kits unused

Protect INP with smaller client islands

Heavy client bundles delay interaction. Prefer Server Components for static sections and hydrate only filters, menus, and media players. Measure after shipping — not only in local demos.

Stabilize CLS

Reserve space for images and embeds. Avoid injecting late-loading banners above existing content. Font loading should use a consistent fallback metric strategy so text does not jump.
