SEO Rankings
Speed is a direct Google ranking factor. Faster sites rank higher in search results.
User Experience
53% of mobile users abandon sites that take over 3 seconds to load.
Conversions
A 1-second delay can reduce conversions by 7%. Speed equals revenue.
Core Web Vitals

General Speed Best Practices
Framework-agnostic techniques: caching, compression, CDN, minification, and critical CSS.
Proven Speed Optimization Techniques
JavaScript Optimization
- •Code splitting: Break large bundles into smaller chunks loaded on demand
- •Tree shaking: Remove unused code from production bundles
- •Defer non-critical scripts: Use async/defer attributes to prevent blocking
- •Minify & compress: Reduce file sizes with UglifyJS and Gzip/Brotli
CSS Optimization
- •Critical CSS: Inline above-the-fold styles, defer the rest
- •Remove unused CSS: Use PurgeCSS or similar tools to eliminate dead styles
- •Minify stylesheets: Compress CSS files for faster downloads
- •Avoid @import: Use link tags instead to enable parallel downloads
Caching Strategies
- •Browser caching: Set long cache headers for static assets (1 year+)
- •CDN caching: Serve static content from edge locations globally
- •Server-side caching: Cache HTML with Redis, Varnish, or built-in solutions
- •Service workers: Implement offline-first caching for PWAs
Server & Network
- •Reduce TTFB: Optimize server response time to under 600ms
- •Enable compression: Use Gzip or Brotli for text-based assets
- •Use HTTP/2 or HTTP/3: Enable multiplexing and faster connections
- •Minimize redirects: Each redirect adds 200-500ms latency
Third-Party Scripts
- •Audit dependencies: Remove unnecessary analytics, ads, and widgets
- •Async loading: Load third-party scripts asynchronously
- •Self-host when possible: Reduce DNS lookups and external dependencies
- •Use facades: Load heavy embeds (YouTube, maps) on user interaction
Advanced Techniques
- •Resource hints: Use preload, prefetch, and preconnect for critical resources
- •Server-side rendering: Send pre-rendered HTML for faster initial paint
- •Edge computing: Run compute closer to users with edge functions
- •Database optimization: Index queries, use connection pooling, enable caching
Frequently Asked Questions
What is website speed optimization?
Website speed optimization is the process of improving page load times through techniques like code minification, image compression, caching, CDN usage, and eliminating render-blocking resources. It directly impacts user experience, SEO rankings, and conversion rates.
How does page speed affect SEO?
Page speed is a direct ranking factor for Google since 2010 (desktop) and 2018 (mobile). Core Web Vitals (LCP, INP, CLS) are official ranking signals since 2021. Faster sites rank higher, appear in more searches, and retain users better, creating a positive SEO feedback loop.
What are the biggest causes of slow websites?
The top causes are: (1) Unoptimized images (50-70% of page weight), (2) Large JavaScript bundles blocking rendering, (3) Render-blocking CSS, (4) Too many third-party scripts, (5) Poor server response time, (6) Lack of caching, (7) No CDN usage. Addressing these can improve speed by 50-80%.
What's a good page load time?
Google recommends: LCP under 2.5 seconds, INP under 200ms, CLS under 0.1. For overall load time, aim for under 3 seconds on 3G networks. Pages loading in 1-2 seconds see the best conversion rates. Each additional second can decrease conversions by 7-20%.
How can I measure my website speed?
Use Google PageSpeed Insights for official Core Web Vitals scores, Lighthouse in Chrome DevTools for detailed audits, and real user monitoring (RUM) via Google Search Console. Test on both mobile and desktop, from different locations, and under various network conditions.
Do I need a CDN for speed optimization?
Yes, CDNs dramatically improve speed by serving content from servers geographically closer to users. They reduce latency by 50-80%, handle traffic spikes, provide DDoS protection, and often include automatic optimization features. CDNs are essential for global audiences.
