Every second your site takes to load can cost you money. This is not a developer's opinion — performance is measurable in user behavior, conversion paths, and search diagnostics.
The Numbers
- 53% of mobile visits are likely to be abandoned if a page takes longer than 3 seconds to load (Google AdSense Help)
- Akamai's online retail performance research linked a 100ms delay with conversion drops of up to 7% (Akamai, State of Online Retail Performance)
- Core Web Vitals measure real user experience across loading, interactivity, and visual stability (web.dev)
Core Web Vitals are not a magic SEO switch. They are part of page quality and user experience. A slow site means a weaker first impression, lower engagement, and fewer chances to turn visitors into leads.
What Makes a Site Slow
Most slow websites share the same problems:
- Unoptimized images — a 4MB JPEG where a 120KB WebP would do
- Render-blocking JavaScript — scripts that prevent the page from showing content
- No caching strategy — downloading the same assets on every visit
- Heavy frameworks loaded eagerly — paying the full bundle cost even for a simple landing page
What We Do Differently
At CoreWeb, performance is not an afterthought. Every site we build:
- Uses AVIF/WebP images via
@nuxt/imagewith responsivesrcset - Ships only the JavaScript needed for each route (Nuxt's automatic code splitting)
- Gets a Lighthouse score above 90 before handoff
- Implements proper cache headers and CDN-ready static output
The Bottom Line
A fast website is a competitive advantage. When your competitor loads in 4 seconds and you load in 0.8s, you've already won the first impression.
If your current site feels slow — let's talk.
