Every 100ms of delay can reduce conversion rates measurably. Performance is not a nice-to-have — it is a competitive advantage, especially on mobile networks in emerging markets.
Focus on LCP, INP, and CLS
- Largest Contentful Paint — optimize hero images and font loading
- Interaction to Next Paint — reduce main-thread blocking JavaScript
- Cumulative Layout Shift — reserve space for ads, images, and embeds
A performance audit before a marketing push often pays for itself within the first campaign. We routinely cut LCP in half with image optimization, code splitting, and smarter caching alone.
