Key takeaways
- The biggest wins are usually images, requests and caching, in that order.
- Do the non-technical items first. They need no deploy and often move the number most.
- Re-measure after each change so you learn which ones actually work on your site.
Hey there! So, you’ve got a website and you’ve noticed it’s running slower than a snail on a lazy Sunday? Don’t worry, you’re not alone. Website speed is crucial – it affects everything from user experience to SEO rankings and even your sales. Whether you’re a non-technical business owner or a seasoned software engineer, this guide is here to help you turn your sluggish site into a lightning-fast machine. Let’s dive into 10 easy steps to boost your website speed!
Non-Technical Quick Wins
Optimize Images
First things first, let’s talk about images. They can be a major culprit for slow loading times. Large, unoptimized images take ages to load and can frustrate your visitors. Here’s how you can fix that:
- Compress Images: Use tools like TinyPNG or JPEG-Optimizer to reduce the file size without losing quality.
- Choose the Right Format: Use JPEG for photos and PNG for graphics with fewer colors. WebP is also a great modern format that offers superior compression.
TinyPNG works in the browser: upload the image, download the compressed copy and replace the original file. To serve modern formats with a fallback for older browsers, use a picture element and give the image its dimensions so the layout does not shift:
<picture>
<source srcset="hero.avif" type="image/avif">
<source srcset="hero.webp" type="image/webp">
<img src="hero.jpg" alt="Product photo on a white background" width="1200" height="630">
</picture>Minimize HTTP Requests
Every element on your website – images, scripts, stylesheets – requires an HTTP request to load. The more requests, the slower the site. Here’s how to cut down on these requests:
- Remove what you do not use: Drop unused third-party libraries, plugins and tag scripts. Plugins such as rich text editors can add a lot of markup and scripts to every page, so check what each one loads.
- Combine Files: Merge multiple CSS and JavaScript files into one.
- Use CSS Sprites: Combine multiple images into a single sprite and use CSS to display them.
Combining files and sprites is advice from the HTTP/1.1 era, when each request needed its own connection slot. Over HTTP/2 and HTTP/3, which multiplex many requests on one connection, it matters much less; removing requests you do not need still helps.
Example of combining CSS files:
<link rel="stylesheet" href="styles.css">
<link rel="stylesheet" href="main.css">
<!-- Combine into -->
<link rel="stylesheet" href="combined-styles.css">Enable Browser Caching
Browser caching stores some of your site’s files on your visitors’ browsers, so they don’t have to download everything again on their next visit. This makes your site load much faster for repeat visitors.
To enable caching, add this code to your .htaccess file:
<IfModule mod_expires.c>
ExpiresActive On
ExpiresByType image/jpeg "access plus 1 year"
ExpiresByType image/gif "access plus 1 year"
ExpiresByType image/png "access plus 1 year"
ExpiresByType image/webp "access plus 1 year"
ExpiresByType image/avif "access plus 1 year"
ExpiresByType image/svg+xml "access plus 1 year"
ExpiresByType font/woff2 "access plus 1 year"
ExpiresByType text/css "access plus 1 month"
ExpiresByType text/javascript "access plus 1 month"
ExpiresByType application/javascript "access plus 1 month"
ExpiresByType application/pdf "access plus 1 month"
ExpiresByType image/x-icon "access plus 1 year"
</IfModule>Use a Content Delivery Network (CDN)
A CDN stores copies of your site’s files in various data centers around the world, ensuring that users access the data from the closest server. This can significantly speed up load times.
Popular CDN providers include Cloudflare and Amazon CloudFront.
Intermediate Strategies for Improved Speed
Minify CSS, JavaScript, and HTML
Minification removes unnecessary characters from your code (like spaces and comments) without changing its functionality. This reduces file size and speeds up load times.
Tools for minification:
- CSS: cssminifier.com
- JavaScript: UglifyJS
- HTML: HTML Minifier
Example of minified CSS:
body{margin:0;padding:0;color:#333;font-family:sans-serif;}Implement Lazy Loading
Lazy loading defers the loading of non-essential resources (like images) until they are actually needed, which speeds up the initial page load.
Optimize Web Fonts
Web fonts can be a big drag on your load times. Here’s how to optimize them:
- Limit the Number of Font Families: Use a few essential fonts.
- Use Modern Formats: Prefer WOFF2 format for better compression.
- Use Font Display: Add
font-display: swapin your CSS to avoid FOIT (Flash of Invisible Text).
Example:
@font-face {
font-family: 'Open Sans';
src: url('opensans.woff2') format('woff2');
font-display: swap;

Leverage Asynchronous Loading for CSS and JavaScript
Synchronous loading makes scripts load one after the other, which can slow down your site. Asynchronous loading allows multiple scripts to load simultaneously.
Example of async and defer:
<script src="script.js" async></script>
<script src="another-script.js" defer></script>Reduce Server Response Time
Server response time, or Time to First Byte (TTFB), is crucial for speed. Here’s how to improve it:
- Upgrade Hosting Plans: Move to a faster, more reliable hosting service.
- Optimize Server Software: Use faster web servers like Nginx.
- Database Optimization: Regularly clean and optimize your database.
Optimize Database Performance
A slow database can bottleneck your entire site. Here’s how to keep it speedy:
- Indexing: Ensure your database tables are properly indexed.
- Query Optimization: Refine your SQL queries for better performance.
- Database Caching: Use caching mechanisms like Memcached or Redis; if you run Redis, monitor it once traffic depends on it.
Tools for monitoring and optimizing:
- New Relic
- MySQL Tuner
