Website performance affects how quickly people can access information and interact with a page. For businesses, that makes performance part of the product experience as well as a technical optimization task.
Start with the largest sources of friction
- Oversized or incorrectly served images.
- Unnecessary client-side JavaScript.
- Slow server responses or poorly configured caching.
- Large third-party scripts and widgets.
- Layout shifts caused by missing dimensions or late-loading assets.
Rendering strategy matters
Server rendering and static generation can make important content available quickly while reducing unnecessary browser work. The correct approach depends on how dynamic the page actually needs to be.
Measure before and after
Performance work should be validated with real measurements rather than assumptions. Review page-level metrics, network activity, JavaScript execution and user journeys before deciding which optimization has the highest practical value.
Performance should be maintained
New marketing tags, images, integrations and features can gradually make a site slower. Performance budgets and regular technical reviews help keep improvements from disappearing after launch.
