How to Speed Up Your Website

Website speed directly impacts user experience, search engine rankings, and conversion rates. Studies show that a one-second delay in page load time can reduce conversions by 7%. Here’s how to make your site faster.

Measure Your Current Speed

Before optimizing, establish a baseline using these free tools:

Google PageSpeed Insights (pagespeed.web.dev)
GTmetrix (gtmetrix.com)
WebPageTest (webpagetest.org)
Lighthouse (built into Chrome DevTools)

These tools provide specific recommendations tailored to your site.

Optimize Images

Images are often the largest files on a page. Reduce their impact by:

Compressing images before uploading (use TinyPNG, ShortPixel, or Squoosh).
Using modern formats: WebP and AVIF offer better compression than JPEG or PNG.
Implementing lazy loading: Load images only when they enter the viewport.
Serving responsive images: Use the srcset attribute to deliver appropriately sized images for each device.

Enable Caching

Caching stores copies of your pages so they load faster for repeat visitors:

Browser caching: Set Cache-Control and Expires headers to tell browsers to store static assets locally.
Server-side caching: Use tools like Varnish, Redis, or a WordPress caching plugin.
CDN caching: A Content Delivery Network caches your site on servers worldwide.

Minify and Combine Files

Minify CSS, JavaScript, and HTML: Remove unnecessary whitespace, comments, and characters.
Combine files: Reduce the number of HTTP requests by merging CSS and JS files where practical.
Defer non-critical JavaScript: Use the defer or async attribute on script tags.

Server-Side Improvements

Upgrade your hosting plan: If you’re on shared hosting and experiencing slowdowns, consider VPS or dedicated hosting from 10Corp for better performance.
Enable GZIP/Brotli compression: Compress files before sending them to the browser.
Use HTTP/2 or HTTP/3: These protocols handle multiple requests more efficiently.
Optimize your database: Clean up overhead, spam comments, and post revisions regularly.

Additional Quick Wins

Remove unused plugins and themes.
Use a lightweight theme or framework.
Reduce external HTTP requests (fonts, scripts, widgets).
Implement DNS prefetching for third-party resources.
Consider using a static site generator for content that rarely changes.

Aim for a load time under 3 seconds. Re-test after each change to verify improvement.
