A Slow Website Is Quietly Costing You Customers (Here's the Fix)

Speed isn't a vanity metric. It's the difference between a visitor who waits and one who's already gone.

Nobody emails to say your site was too slow — they just leave and never come back. Speed is the most expensive problem you can't see.

What Core Web Vitals actually measure

Google grades how fast your main content appears (LCP), how stable the layout is (CLS), and how quickly the page responds to taps (INP). Together they're a proxy for 'does this feel fast and trustworthy?'

Speed is a ranking and conversion lever

Faster sites rank higher and convert better — the effect compounds because Google sends more traffic to a page that already turns more visitors into leads.

The usual culprits are fixable

Oversized images, bloated scripts, and cheap hosting cause most slowdowns. Modern builds fix these by default, which is why a rebuild often pays for itself in conversions.
