Core Web Vitals: Speed is Money
By InoConnect Strategy Team •
The 2.5 Second Rule
Google has drawn a line in the sand. If your page takes longer than 2.5 seconds to load the “Largest Contentful Paint” (LCP), you are failing.
The Metrics Explained
1. LCP (Largest Contentful Paint)
What: How fast the main image/text loads. Fix: Use Next/Image or Astro’s image optimization. Use WebP formats. Preload hero images.
2. INP (Interaction to Next Paint)
What: Responsiveness. When I click “Menu,” does it open instantly or lag? Fix: Reduce main-thread JavaScript blocking.
3. CLS (Cumulative Layout Shift)
What: Visual stability. Does the button jump down when an ad loads? Fix: Reserve space for images/ads with explicit width/height attributes.
The Revenue Impact
Deloitte found that improving mobile site speed by 0.1s increased conversions by 8.4% for retail sites.
Speed isn’t a tech metric. It’s a revenue metric.
