In 2021, Google officially added Core Web Vitals as ranking signals — making page speed a direct factor in where your website appears in search results. A slow website isn't just a bad user experience; it's an SEO handicap that pushes you down the rankings and into your competitors' arms.

Revenue drop for every 1-second delay in load time

Higher bounce rate for pages loading in 5s vs 1s
Google's Core Web Vitals Explained
LCP (Largest Contentful Paint)
Measures how quickly the main content of a page loads. Google's target: under 2.5 seconds.
FID (First Input Delay)
Measures the time from a user's first interaction to when the browser responds. Target: under 100ms.
CLS (Cumulative Layout Shift)
Measures visual stability — how much page elements shift during loading. Target: under 0.1.
INP (Interaction to Next Paint)
The newest metric, replacing FID — measures overall page responsiveness to all user interactions.
Common Speed Killers on South African Websites
- Unoptimized images (often the single biggest culprit — use WebP format and compress all images)
- Render-blocking JavaScript and CSS that delays page display
- No browser caching — visitors re-download everything on each visit
- Shared hosting with slow server response times (TTFB over 200ms)
- Too many third-party scripts (chat widgets, analytics, ad pixels)
- No Content Delivery Network (CDN) for serving assets quickly across SA
