Performance & Care

Set a Website Performance Budget Before the Redesign

Define limits for images, fonts, scripts, widgets, requests, and Core Web Vitals before visual concepts create an expensive page to optimize later.

Performance is easier to protect than to rescue

A redesign can add large photography, video, animation, font files, analytics, chat, review widgets, booking tools, and marketing tags before anyone defines a loading target. A performance budget turns speed into a design and engineering constraint from the start.

What to review

Choose representative mobile and desktop page templates.
Set practical limits for transferred bytes, requests, fonts, JavaScript, and third-party work.
Define LCP, INP, CLS, accessibility, and functional acceptance criteria.
Require every new widget or animation to justify its customer value and cost.

A practical implementation plan

Measure the current site
Capture lab and field data, page weight, request count, major assets, and customer-critical paths.
Set template budgets
Give the home, service, article, gallery, and contact flows appropriate constraints.
Automate and review
Add build or release checks and review exceptions with evidence rather than silently raising limits.

What to measure

Track Core Web Vitals, page weight, requests, script time, errors, conversion paths, and device-specific feedback. A fast empty page is not the goal; useful content must remain clear.

Connect the insight to the customer journey

Include the budget in design reviews, content guidance, integration approval, and post-launch maintenance so improvements survive future campaigns.
