Website speed is a confirmed Google ranking factor. Slow websites rank lower, convert fewer visitors, and provide a worse user experience. Here's how to optimize your website speed for better SEO performance.
Why Speed Matters for SEO
Google's Core Web Vitals are a set of performance metrics that directly impact your search rankings:
- LCP (Largest Contentful Paint) - how long the main content takes to load. Target: under 2.5 seconds
- INP (Interaction to Next Paint) - how quickly the page responds to user input. Target: under 200ms
- CLS (Cumulative Layout Shift) - how stable the page is as it loads. Target: under 0.1
According to Google's Web Vitals documentation, sites that meet these thresholds rank better and provide a better user experience.
Image Optimization
Images are typically the largest files on any web page and the #1 cause of slow load times.
Best Practices
- Use modern formats - WebP and AVIF are 25-50% smaller than JPEG/PNG
- Resize images - serve images at the actual display size, not larger
- Lazy load - only load images when they enter the viewport
- Use responsive images - serve different sizes for different screen widths
- Compress aggressively - most images can be compressed 60-80% without visible quality loss
Minimize JavaScript and CSS
Bloated code is a common speed killer, especially on WordPress sites with many plugins. Each script and stylesheet adds to load time.
- Remove unused plugins - every plugin adds code overhead
- Minify files - strip whitespace and comments from production code
- Defer non-critical scripts - load JavaScript after the main content renders
- Use modern frameworks - Next.js, for example, automatically optimizes JavaScript bundling
Choose Better Hosting
Cheap shared hosting is one of the biggest speed bottlenecks. If your hosting costs $5/month, you're sharing server resources with hundreds of other sites.
- Use a CDN - serve content from servers closest to your visitors
- Choose SSD storage - faster than traditional hard drives
- Consider managed hosting - optimized specifically for your platform
Browser Caching
Browser caching tells returning visitors' browsers to store certain files locally, so they don't need to be downloaded again. This dramatically speeds up repeat visits.
Set cache headers for static assets (images, CSS, JavaScript) with expiration times of at least one month.
Test and Monitor Your Speed
