Mobile performance budgets for brochure sites
Short answer: A performance budget caps page weight and script time so marketing cannot stack widgets until the site collapses.
NZ brochure sites should stay lean—customers on mobile data reward fast first screens.
Example budget lines
- Total page weight under an agreed KB for homepage on mobile.
- Limit third-party script count.
- Maximum hero image dimensions encoded in the CMS.
Enforcement
Automated checks in CI or monthly Lighthouse budgets; block launches that regress without ticketed exceptions.
Culture
Treat speed as product quality—not only “dev’s problem”. If you need help building fast sites, NZDH works with NZ businesses on performance-grounded builds.
