Web Performance Is a Business Decision, Not a Technical One
Every 100ms of load time costs you conversions. Here's how to make the case for performance investment.
The Numbers Nobody Argues With
A 1-second delay in page load reduces conversions by 7%. For a business doing $10M annually online, that’s $700K left on the table. Performance isn’t optimization — it’s revenue.
Speed is a feature. The fastest experience always feels like the best experience, regardless of what else you ship.
Where the Seconds Go
Most performance problems aren’t in the code. They’re in the decisions made before code was written:
- Images without size constraints — the single biggest offender
- Third-party scripts loaded synchronously — analytics, chat widgets, social embeds
- Fonts that block rendering — four weights of a typeface nobody notices
The Fix
Measure first. Core Web Vitals give you three numbers that matter: LCP, FID, and CLS. Improve the worst one first. For most sites, that’s LCP — and the fix is usually simpler than expected.
Ship less. Compress what remains. Cache everything possible. The best performance optimization is the code you never wrote.
