Core Web Vitals Checklist For Website Redesigns

Performance has to be designed in

A redesign can look stronger while becoming slower if media, fonts, animations, scripts, and layout dimensions are not controlled.

Core Web Vitals work is most useful when it sits beside content hierarchy, mobile layout, conversion paths, and technical SEO rather than being treated as a late-stage audit.

• Largest Contentful Paint risk from oversized hero media
• Interaction delay from unnecessary client-side JavaScript
• Layout shift from images, cards, embeds, or forms without reserved space
• Font loading decisions that change page rhythm after render
• Third-party scripts that do not support the buyer journey

What to check before launch

Priority pages should be checked on mobile and desktop before the new site replaces the old one. The goal is not a perfect lab score in isolation; the goal is a fast, stable, useful page that supports real buyers.

The same review should cover image dimensions, preload priority, page source, metadata, structured data, forms, and navigation.

• Hero image size, priority, alt treatment, and object position
• Reserved card, media, and form dimensions to reduce layout shifts
• Fonts loaded from the app rather than slow external calls
• Only necessary client components and scripts
• Rendered checks for primary conversion routes

How 760 Studios applies it

760 Studios treats performance as part of design quality. A premium site should feel composed, stable, and quick enough that the buyer can focus on the offer.

The practical output is a short fix list tied to priority URLs, not a disconnected report that nobody implements.

Performance-first redesign checklist

• Hero media: confirm size, format, priority, object position, and mobile crop before launch.
• Layout stability: reserve dimensions for cards, images, forms, embeds, and repeated sections.
• JavaScript: keep marketing pages server-rendered unless interaction is genuinely needed.
• Fonts: use app-hosted fonts and avoid late swaps that change visual rhythm.
• QA: check the priority routes in a browser, not only through build output.

Common mistakes to avoid

• Approving a visual concept before checking how the hero image behaves on mobile.
• Adding decorative motion or scripts that do not improve the buyer journey.
• Treating Core Web Vitals as an afterthought after templates are already fixed.

What 760 Studios would review first

• Priority template and media risks
• Layout shift sources
• First technical fixes before launch

Studio note

760 Studios connects brand, content, UX, frontend quality, and search foundations so the recommendation is tied to the commercial job of the site, not a generic checklist.
