How Fast Should a Business Website Load? Core Web Vitals Benchmark

Google research confirms that as page load times increase from 1 second to 3 seconds, the probability of a mobile bounce increases by 32%. For US businesses investing in paid media or SEO, speed is directly correlated with customer acquisition cost.

Understanding Google Core Web Vitals

  • Largest Contentful Paint (LCP): Measures when the main content of a page is visible. Target: Under 2.5 seconds (EnsignStreet target: Under 1.2s).
  • Interaction to Next Paint (INP): Assesses page responsiveness to user clicks and taps. Target: Under 200 milliseconds.
  • Cumulative Layout Shift (CLS): Measures visual stability during rendering. Target: Score under 0.1.

Engineered for Raw Speed

By using clean vanilla CSS, deferred script execution, and modern responsive image formats, EnsignStreet ensures your website loads virtually instantaneously on both fiber desktop and 4G mobile networks.
