How to Speed Up Your Website
Published: September 2026Website speed is no longer just a technical detail in the background — it is one of the first impressions visitors get of your brand, and one of the factors Google measures when evaluating page experience and search performance. A website that takes several seconds to load can lose visitors before they even see what you offer.
Below, we go through seven steps we regularly apply when building websites — from image and video optimization to code, fonts, hosting and performance measurement. These are not abstract tips, but practical changes that can make a real difference to loading speed.
If you want us to check how fast your website currently performs and what can be improved, take a look at our website development pricing or contact us directly.
7 Steps to a Faster Website
01
Optimize Images Before Uploading Them
Images are often the single biggest cause of slow loading times. Instead of multi-megabyte JPG or PNG files, use WebP or AVIF, which can deliver similar visual quality at a much smaller file size. Also, an image should never be significantly larger than the space where it is displayed — if the container is 800px wide, there is usually no reason to load a 3000px-wide image.
- WebP/AVIF instead of JPG/PNG
- Correct dimensions for display
- Compression without noticeable quality loss
- Lazy loading for off-screen images
02
Do Not Let Video Content Slow You Down
Video on a homepage or portfolio can look impressive, but if it loads automatically before it is even visible, it may download tens of megabytes before the visitor scrolls. The solution is lazy loading, similar to images — load the video only when the user reaches it, and pause it when it leaves the viewport.
- Lazy-load video with IntersectionObserver
- No autoplay for heavy video files
- Compression and appropriate resolution
- Pause video when it is not visible
03
Minify and Clean Up CSS and JavaScript
Every character in CSS and JavaScript files — spaces, comments and unused code — has to be transferred to the visitor's browser. Minification removes what is not necessary for the code to run, while regularly removing unused styles and scripts prevents files from growing over time for no reason.
- Minified CSS and JavaScript
- Unused code removed
- Files combined where it makes sense
- Deferred loading of non-critical code
04
Choose Hosting That Matches Your Needs
Even the best-optimized website will not perform well on slow or overloaded hosting. Quality hosting with strong infrastructure, server-side caching and a CDN that serves files from a location close to the visitor can often make a bigger difference than any single code optimization.
- Reliable and fast hosting
- Server-side caching
- CDN for static files
- HTTP/2 or HTTP/3 support
05
Use Browser Caching
When a visitor returns to your website, they should not have to download the same files again. Properly configured Cache-Control headers tell the browser how long to store images, styles and scripts locally, making repeat visits significantly faster.
- Cache-Control headers
- Longer caching for static files
- Faster repeat visits
- Less load on the server
06
Load Fonts and Third-Party Scripts Carefully
Google Fonts, analytics tools, chat widgets and other external scripts can quietly slow a website down because they depend on resources loaded from third-party servers. It is usually better to limit fonts to a small number of variants and use font-display: swap, while third-party scripts should be delayed with async or defer until the essential content has loaded.
- font-display: swap
- Limited number of font variants
- Async/defer for external scripts
- Delayed loading of analytics where appropriate
07
Measure Performance Regularly
Website speed is not something you optimize once and then forget. A new image, additional widget or other change can gradually slow the website down over time. Tools such as Google PageSpeed Insights and Lighthouse measure specific performance metrics such as LCP, INP and CLS and can help identify what is currently affecting performance. It is good practice to check the results after every major change.
- Google PageSpeed Insights
- Core Web Vitals: LCP, INP, CLS
- Performance checks after major changes
- Track performance trends over time
