Why Page Speed Matters More Than You Think
Every second of load time costs you visitors, conversions, and search rankings. The numbers and what to do about it.
Google's research shows 53% of mobile users abandon sites that take longer than 3 seconds to load. That's not a small deal. More than half your potential visitors gone before they see anything.
The Business Impact
Amazon found every 100ms of latency cost them 1% in sales. Walmart saw 2% more conversions for every 1 second of improvement. Enterprise numbers, sure, but the principle applies everywhere: faster sites convert better.
Page speed is also a direct Google ranking factor. Core Web Vitals (LCP, FID, CLS) are baked into the ranking algorithm. Two identical sites with different performance scores rank differently. Simple as that.
The Usual Culprits
Unoptimized images are the #1 offender. A single 4MB hero image that should be 200KB adds 3+ seconds to load time. Use WebP/AVIF, proper sizing, and lazy loading for below-the-fold images.
Too much JavaScript. Every KB of JS gets downloaded, parsed, and executed. Page builder themes often ship 500KB+ of JS for features you never use. Custom sites typically need a fraction of that.
No caching strategy. Without proper cache headers and CDN setup, every visitor downloads every asset from scratch. A well-configured CDN cuts load times 60-80% for repeat visitors.
Render-blocking resources. CSS and JS files in the document head that block the browser from painting anything until they're fully loaded. Critical CSS inlining and async/defer loading solve this.
What Good Looks Like
We target 90+ on all four Lighthouse categories for every project. Our latest projects consistently hit Performance 95+, Accessibility 100, Best Practices 95+, SEO 100. Not aspirational. That's our baseline.
If your site scores below 70 on any category, there's room to improve. Run a Lighthouse audit (free in Chrome DevTools) and see where you stand.
